A 10-ft moving truck has a volume capacity of 402 cubic feet, which is equivalent to 1.138 x 10⁷ milliliters. What mass of silve
steposvetlana [31]

Answer:

The mass of silver is 1.19\times 10^{14}\ Mg

Explanation:

Given that,

The volume of the truck is 402 cubic feet or 1.138 x 10⁷ mm.

The density of silver is 10.49 g/mL.

We need to find the mass of silver that will fit in this moving truck. Density equals mass divided by volume. So,

d=\dfrac{m}{V}\\\\\text{where m is mass}\\\\m=d\times V\\\\m=10.49\ g/mL\times 1.138 \times 10^7\ mL\\\\m=119376200\ g

1 gram = 10⁻⁶ Megagram

119376200=1.19\times 10^{14}\ Mg

Hence, the mass of silver is 1.19\times 10^{14}\ Mg

Hypothesis: Explain the relationship between forward and reverse reactions at equilibrium and predict how changing the amount of
postnew [5]

Explanation:

forward reaction

a reaction in which reactent react to form product is known as forward reaction

reverse reaction

a reaction in which product react to form reactent is known as reverse reaction

At equilibrium stage

In a chemical equilibrium, the forward and reverse reactions occur at equal rates, and the concentrations of products and reactants remain constant. A catalyst speeds up the rate of a chemical reaction, but has no effect upon the equilibrium position for that reaction.

changing amount of reactent and product

lechatlier principle

" if you impose any change in concentration ( reactant or product) , temperature or pressure on chemical system, the system response in that way that opposes the change "
