Answer: this is the explanation
Explanation:
the temperature of a substance is related to the average kinetic energy of the particles of that substance. When a substance is heated, some of the absorbed energy is stored within the particles, while some of the energy increases the motion of the particles
How is agriculture depended on industries
Answer:
The interdependence of agriculture and industry helps the development of both the sectors. The most important aspect of this inter dependence is that the products of one serve as important inputs for the other. Growth of one sector, thus means ample supply of inputs for the other.
Explanation:
Why is methanol more soluble in water than butanol
Answer:
Explanation: The longer the alkyl chain, the less soluble in water is the alcohol. Methanol and ethanol are infinitely miscible in water; propanol and butanol have limited solubility. ... Hydrogen bonding with water thus becomes less viable, and solubility of the long-chain alcohol IN WATER decreases.

Why do we sometimes use roman numerals in naming ionic compounds?
We use roman numerals to indicate the oxidation state of metal atoms when naming compounds especially in the case of coordination compounds. It is a standard system of nomenclature.
What is oxidation state?Oxidation state of a species is the number electrons gained or lost. Oxidation state increases if electrons are lost from the atom and it will be decreased if electrons are gained.
For example, copper is in + 2 oxidation state in CuSO₄, thus it can be indicated as Cu(II). Copper can exists is +3 oxidation too. Thus the representation will be Cu (III).
All the transition metals like copper exhibit various oxidation state. So it is important to indicate in which oxidation state they are in a particular compound. In the compound Fe₂O₃, iron is in + oxidation state whereas in FeSO₄, it can be +2 . Thus it is important to note whether it is Fe (II) or Fe (III).

how many molecules are in 0.89 of silver
Answer:
5.36 × 10²³ molecules
Explanation:
Given data:
Number of moles of silver = 0.89 mol
Number of molecules = ?
Solution:
Avogadro number:
The number 6.022 × 10²³ is called Avogadro number.
It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.
For example,
18 g of water = 1 mole = 6.022 × 10²³ molecules of water
1.008 g of hydrogen = 1 mole = 6.022 × 10²³ atoms of hydrogen
Number of molecules of silver:
1 mole contain 6.022 × 10²³ molecules
0.89 mol × 6.022 × 10²³ molecules /1 mol
5.36 × 10²³ molecules

the electrolyte in automobile lead storage batteries is a 3.75 sulfuric acid solution that has density of 1.230g/mL. calculate the mole fraction.
The mole fraction of sulfuric acid : 0.073
Further explanationGiven
3.75 M sulfuric acid solution that has density of 1.230 g/mL
Required
The mole fraction
Solution
3.75 M = 3.75 mol/L
For 1 L solution :
mass of solution = 1230 g
mass Sulfuric acid : 3.75 mol x 98 g/mol=367.5 g
mass water = 1230-367.5 = 862.5 g
mol water = 862.5 : 18 g/mol= 47.92
mol total = 3.75 + 47.92 = 51.67
mole fraction of sulfuric acid :
= 3.75 : 51.67
= 0.073

How is the chemical bonding within a crystal of gold (Au) different from the
chemical bonding within a crystal of table salt (NaCl)?
Answer:
In the gold crystal, the atoms are bonded by freely moving electrons. In the salt crystal, the atoms are bonded by the attraction of opposite electrical charges.
Explanation:
A.pex
A crystal of Gold (Au) has metallic bonding whereas a crystal of NaCl has ionic bonding.
What is Chemical Bonding?Chemical bonding refers to the formation of a chemical bond between two or more atoms, molecules or ions to give rise to a chemical compound.
Ionic bonding occurs by transfer of electrons from one atom to another and is usually between a metal and a non metal atom. This type of bond is classically described as occurring when atoms interact with one another to either lose or gain electrons.
Metallic bonds are the chemical bonds that hold atoms together in metals.
Therefore, A crystal of Gold (Au) has metallic bonding whereas a crystal of NaCl has ionic bonding.

What will be the mass of 9.95 liters of propane gas (C3H8) at STP?
Answer:
19.5g
Explanation:
Given parameters:
Volume of propane gas = 9.95L
Unknown:
Mass of propane gas = ?
Solution:
To solve this problem, find the number of moles first.
At STP;
22.4L of gas makes up 1 mole
9.95L of gas will have a [tex]\frac{9.95}{22.4}[/tex] = 0.44mole
So;
Mass of propane gas = number of moles x molar mass
Molar mass of propane = 3(12) + 8(1) = 44g/mol
Mass = 0.44 x 44 = 19.5g
