After a rock is rounded how does weathering affect it

Answers

Answer 1

Answer: After a rock is rounded, then also weathering is going to affect it. Although the rocks with rough angles get weathered more quickly, but still a rounded rock will ultimately start weathering and becoming smaller in size. Weathering can not only alter the rock physically, but it can also alter the rounded rock chemically depending on the material by which it is made of. Biological weathering can always weather away a rock without depending on its shape or size. There are other forms of weathering also that can impact the rounded rock.

The rates of the forward and reverse reactions are unequal.
The concentrations of the products and reactants do not change.
The forward reaction stops at 500 K.

Answers

The correct option is this: THE CONCENTRATION OF THE PRODUCTS AND THE REACTANTS DO NOT CHANGE.

A reversible chemical reaction is said to be in equilibrium if the rate of forward reaction is equal to the rate of backward reaction. At this stage, the concentrations of the products and the reactants remain constant, that is, there is no net change in the concentration even though the reacting species are moving between the forward and the backward reaction.

If the reaction is at dynamic equilibrium at 500 K, the statement that applies to the given chemical system is The concentrations of the products and reactants do not change.

methane and hydrogen sulfide form when hydrogen reacts with carbon disulfide. identify the excess reactant and calculate how much remains after 36 L o fH2 reacts with 12 L of CS2 all at STP

Answers

At STP, 1 mol of gas occupies 22.4 L of volume. Using this conversion we the starting amounts of the reactants:
1.6071 mol H2
.5357 mol CS2
The balanced equation is:
4H2 + CS2 -> CH4 + 2H2S
This means that 4 moles of H2 reacts with 1 mole of CS2.
Multiplying this ratio with each of the amounts of the reactants:
required CS2 based on amount of H2 = 0.4018 mol CS2
required H2 based on amount of CS2 = 2.1428 mol H2
Therefore, the excess reactant is CS2. To calculate how much is left, we simply subtract the amount of the reactant CS2 with the required amount based on the amount of H2:
0.5357 mol - 0.4018 mol = 0.1339 mol

A salt is obtained as a reaction between .A. a base and water.
B. a nonmetal and a metal.
C. an acid and oxygen.
D. a base and an acid.

Answers

A salt is obtained as a reaction between a base and an acid which is option D.

A salt is obtained as a reaction between a base and an acid. In this reaction, the base donates a hydroxide ion (OH⁻) and the acid donates a hydrogen ion (H⁺). The hydroxide ion and hydrogen ion combine to form water (H₂O), and the remaining ions from the base and acid combine to form the salt. The salt is typically composed of a metal cation from the base and a non-metal anion from the acid. The formation of salt is a neutralization reaction where the acidic and basic properties of the reactants are neutralized, resulting in the formation of a new compound, the salt.

Hence, the correct option is option d.

At STP, 1.0 liter of helium contains the same total number of atoms as(1) 1.0 L of Ne (3) 0.5 L of Rn
(2) 2.0 L of Kr (4) 1.5 L of Ar

Answers

Answer: (1) 1.0 L of Ne

Explanation: According to Avogadro's law, 1 mole of every gas occupy 22.4 Liters at STP and contains avogadro's number $6.023* 10^(23)$ of particles.

Avogadro's Law: This law states that volume is directly proportional to the number of moles of the gas at constant pressure and temperature.

$V\propto n$ (At constant temperature and pressure)

Thus equal volumes contain equal number of atoms.

Hence, 1.0 liter of helium contains the same total number of atoms as

1.0 L of Ne at STP.

The answer is (1) 1.0 L of Ne. The gases under same condition with same volume have the same molar number. And the question is asking the number of atoms. Because the elements given all have same number of atoms when having same molar number.

How many moles of oxygen (O2) are required to completely react with 27.4 mol of H2?

Answers

This reaction can be written as
H2 + O2 => H2O.
Then, balanced, as
2H2 + O2 = 2H2O

There we see that we need 2 times more mol of H2 than O2. So mol of O2 is 1/2 mol of H2. That is 27.4 mol / 2 = 13.7 mol.

Answer:
