Answer:
There are several benefits farmers and owners of agribusinesses.
It is often said that one cannot manage what they can't measure. Data helps farmers manage with better efficiency their operations. They can make more tailored decisions with respect to their farm’s specific needs if they have more information.When data is obtained and analysed, it generates information. The information obtained can help farmers identify efficiencies that lead to higher productivity and profitability, lower input costs, and optimise use of important farm input such as fertiliser and feed.Data help farmers reduce the risks associated with their operations. One of such risks is Market risks. If a farmer has adequate information about how a particular product is performing in the market with respect to demand and trends, it helps them plan production in such a way that they don't over produce thus creating a surge in supply which can lower prices. This is also beneficial to a farms supply chain relationships or network.Cheers!
Two identical atoms from Area B bond together. What type of bond will they most likely form
A. Electrostatic
B. Metallic
C. Ionic
D. Covalent
Answer:
Covalent Bonding
Explanation:
If atoms have similar electronegativities (the same affinity for electrons), covalent bonds are most likely to occur. Because both atoms have the same affinity for electrons and neither has a tendency to donate them, they share electrons in order to achieve octet configuration and become more stable.
what makes a question able to be answered by science?
_______ is melted rock that does not reach earth's surface; intrusive igneous rocks form as magma slowly cools under the surface.
The blank should be filled with "Magma". Magma is melted rock beneath the Earth's surface. When magma slowly cools underground, it forms intrusive igneous rocks.
Magma is a mixture of molten rock, minerals, and gases that forms beneath the Earth's surface. It originates from the partial melting of rocks in the Earth's mantle or crust due to high temperature and pressure conditions.
When magma rises towards the Earth's surface, it can solidify underground before reaching the surface. This process occurs when the magma cools slowly over a long period of time. As it cools, the minerals within the magma crystallize and solidify to form intrusive igneous rocks. Since this process happens below the surface, intrusive igneous rocks are also known as plutonic rocks.
Intrusive igneous rocks have a coarse-grained texture because the slow cooling allows sufficient time for large mineral crystals to form. Examples of intrusive igneous rocks include granite, diorite, and gabbro. These rocks can be exposed at the Earth's surface through uplift and erosion, revealing the once-buried formations.

how many carbon atoms are in 4.00g of butane
Answer: 1.6221*10^23 atoms
Explanation:
Butane = C4H10
Molar mass = 58g/mol
1 mole of butane has 4 carbon atoms.
% of carbon in 1 mole of C4H10 = 4*12/58 =82.8%
Mass of carbon in 4g of butane = 82.8/100 *4 = 3.312g.
3.312g of carbon is equal to how many moles of carbon?
No.of moles = mass/ molar mass
3.312/12 = 0.276 moles.
Using Avogadro's number,
Number of atoms in any substance = Avogadro's constant * no of moles of that substance
(6.02214*10^23) * 0.276 = 1.6221*10^23 atoms.

What is the average atomic mass of a sample of naturally occurring x, if it is comprised of the following isotopes 47% ^51X, 17% ^52X and 36% ^56X
The average atomic mass of a sample of naturally occurring element X, comprised of isotopes ^51X, ^52X, and ^56X with natural abundances of 47%, 17%, and 36%, is calculated to be 52.97 atomic mass units (amu).
Explanation:The average atomic mass of a sample of naturally occurring X can be calculated by taking into account the natural abundance of its isotopes. To find the average atomic mass of element X, we multiply the mass number of each isotope by its respective natural abundance (converted to a fraction), and then add these values together.
For isotopes ^51X, ^52X, and ^56X with natural abundances of 47%, 17%, and 36%, respectively, we calculate the average atomic mass as follows:
(47%/100) x 51 = 23.97 amu(17%/100) x 52 = 8.84 amu(36%/100) x 56 = 20.16 amuSumming these products gives us:
23.97 amu + 8.84 amu + 20.16 amu = 52.97 amu
Therefore, the average atomic mass of naturally occurring X is 52.97 amu.

how many valence electron do silver have
The number of valence electron in silver is one.
Valence electrons are the electrons that are found in the outermost shell of an atom. They are the electrons that are involved in chemical bonding.
The atomic number of silver is 47, which means that there are 47 protons in the nucleus of a silver atom. The number of electrons in a neutral atom is equal to the number of protons in the nucleus. This means that there are also 47 electrons in a neutral silver atom.
The electron configuration of silver is [Kr] 4d¹⁰ 5s¹. This means that the outermost shell of silver has 1 electron. The 4d¹⁰ electrons are filled, and the 5s¹ electron is the valence electron.
The valence electron of silver is important for its chemical properties. Silver is a good conductor of electricity because the valence electron is easily removed from the atom. This allows silver to form bonds with other atoms and conduct electricity.

what is the eccentricity of earth
The eccentricity of Earth's orbit is a measure of its elliptical shape and is calculated using the distance to the foci and the semi-major axis of the orbit. Earth's orbital eccentricity is approximately 0.0167, indicating it is nearly circular with a slight elongation.
Explanation:The eccentricity of Earth's orbit is a measure of its deviation from a perfect circle. The orbit of Earth is slightly elliptical, with an eccentricity that is generally known to be less than 0.1, which means it is very close to circular. To calculate the eccentricity (e), one can use the formula e = f/a, where f is the distance from the center of an ellipse to one of the foci, and a is half the long axis of the ellipse.
For Earth's orbit, we have an average semi-major axis of approximately 1.496 × 10¹ meters (the average distance from the Earth to the Sun) and specific calculations yield an eccentricity value of approximately 0.0167. This is indeed less than 0.1, confirming that Earth's orbit is nearly circular, but with a slight elongation.
find the density of a substance whose volume is 5 cm^3 and whose mass is 25 g.
You may calculate a substance's density by dividing its mass by its volume. Given a mass of 25 g and a volume of 5 cm^3, the density of the substance would be 5 g/cm^3.
Explanation:The density of a substance is calculated using the formula density = mass/volume. In this case, the mass of the substance is 25 grams and the volume is 5 cm3.
To calculate the density, we would dividing the mass by the volume, thus: density = 25 g / 5 cm3 = 5 g/cm3.
Therefore, the density of the substance is 5 g/cm3.

Which method would be best to separate a mixture of oil and water? separation by density separation by particle size filtration distillation
The most effective method to separate oil and water is by using density differences with a separatory funnel. Distillation is also suitable but more complex. Filtration and separation by particle size are not appropriate for this mixture.
The student asked: Which method would be best to separate a mixture of oil and water?
The best method to separate a mixture of oil and water is separation by density. Since oil and water have different densities, the oil will float on top of the water. Using a separatory funnel, you can pour out the water from the bottom, leaving the oil behind.
Another method that could be used is distillation. Since water and oil have different boiling points, heating the mixture will allow the water to boil and be collected separately from the oil. However, this method is more complex and generally less practical for simple separation tasks.
Filtration and separation by particle size are not effective methods for this type of mixture because both oil and water are liquids and do not have different particle sizes or solid components that can be filtered.

the _________ contains the majority of the mass of the atom but is much ________ than the atom. A) nucleus, smaller B) neutrons, larger C) electron cloud, smaller D) pions and quarks, larger
Answer:
A) nucleus, smaller
Explanation:
The structure of an atom can be explained based on Rutherford's model according to which, most of the mass of an atom is concentrated in its positively charged core called the 'nucleus' whereas the negatively charged electrons move around it in fixed paths called orbits. The radius of the nucleus however is much smaller than that on the atom.
An element is usually represented in terms of its atomic mass (A) and atomic number(Z).
Atomic mass = protons + neutrons
Atomic number = number of protons
Therefore, the __nucleus_______ contains the majority of the mass of the atom but is much _smaller_______ than the atom.
