What has more particles: a mole of hydrogen or a mole of uranium?

The correct statements are a denovo anabolism of nucleotides d myosin action during muscle contraction e membrane transport that maintain levels in the cell.

Explanation:

ATP or adenosine tri phosphate is an high energy compound.The hydrolysis of ATP helps to drive many thermo dynamically unfavorable reaction.The processes which are coupled to the de phosphorylation of ATP are given below.

1 De novo synthesis of nucleotides that requires energy in form of ATP.

2 During muscle contraction the sliding of thick filaments or myosin over thin filament or actin requires energy derived from the hydrolysis of ATP.

3 Membrane transport basically active transport helps in the uphill transport of ions that requires free energy in form of ATP.

If 40.0 grams of magnesium is reacted with an excess of nitric acid. 3.3 g of hydrogen gas will be produced.

<h3>What is Stoichiometry ?</h3>

Stoichiometry helps us use the balanced chemical equation to measure quantitative relationships and it is to calculate the amounts of products and reactants that are given in a reaction.

<h3>What is Balanced Chemical Equation ?</h3>

The balanced chemical equation is the equation in which the number of atoms on the reactant side is equal to the number of atoms on the product side in an equation.

Now we have to write the balanced equation

Mg + 2HNO₃ → Mg(NO₃)₂ + H₂

According to Stoichiometry

$40.9\ \text{g Mg} \times \frac{1\ \text{mol Mg}}{24.31\ \text{g Mg}} \times \frac{1\ \text{mol}\ H_2}{1\ \text{mol Mg}} \times \frac{2.02\ g\ H_2}{1\ \text{mol}\ H_2}$

= 3.3 g H₂

Thus from the above conclusion we can say that If 40.0 grams of magnesium is reacted with an excess of nitric acid. 3.3 g of hydrogen gas will be produced.

Which of the following is required to change the state of matter?

nignag [31]

Since there are no given items, I will give a general answer. Energy....or the lack of it. Examples: Heat, electricity, force (when an item is moving and it impacts something, it heats up...friction is an example of this), etc
