Polymerization is most directly responsible in determining which structure of a protein?

d1i1m1o1n [39]

Polymerization is the chemical reaction between monomer molecules. The result of the reaction are polymer chains or three-dimensional networks. A polymer is build from several blocks - monomers. Polymerization is most directly responsible in determining the primary structure of a protein.

In an exothermic reaction, chlorine reacts with 2.0200g of hydrogen to form 72.926g of hydrogen chloride gas. how many grams of

Artemon [7]

Answer : 70.906 grams of chlorine reacted with hydrogen

Explanation :

Step 1 : Write balanced chemical equation.

The balanced chemical equation for the reaction between hydrogen and chlorine gas is given below.

$H_{2} (g) + Cl_{2} (g) \rightarrow 2HCl(g)$

Step 2 : Find moles of H₂ gas.

The moles of H₂ can be found as

$mole = \frac{grams}{MolarMass}$

We have 2.0200 g of H₂ and molar mass of H₂ is 2.02 g/mol.

Let us plug in these values to find moles of H₂.

$mole =\frac{2.0200g}{2.02g/mol} = 1 mol$

We have 1 mol of H₂.

Step 3 : Find moles of Cl₂ using mole ratio.

The mole ratio of H₂ and Cl₂ is 1 : 1.

The moles of Cl₂ can be calculated as

$1 mol H_{2} \times\frac{1 mol Cl_{2}}{1 mol H_{2}} = 1 mol Cl_{2}$

Step 4 : Find grams of Cl₂.

Molar mass of Cl₂ gas is 70.096 g/mol

Mass of Cl₂ = $1 mol Cl_{2} \times\frac{70.906g}{mol} = 70.906 g$

We have 70.906 grams of Cl₂

What is the molar ratio of Li to N2 in the given reaction?<br><br> 6Li + N2 → 2Li3N

givi [52]

Answer:

6moles of Li : 1 mole of N₂

Explanation:

The reaction equation is given as:

6Li + N₂ → 2Li₃N

Mole ratio of Li to N₂;

From the balanced reaction equation:

6 moles of Li will react with 1 mole of N₂;

The mole ratio is:

6moles of Li : 1 mole of N₂
