when chlorine is added to acetylene tetrachloroethane is formed How many grams of tetrachloroethane are ade if 15 liters of chlo
rodikova [14]

35.5 g of tetrachloroethane is added if 15 grams of chlorine is used with excess C_2H_2.

<h3>What is a balanced chemical equation?</h3>

A balanced equation is an equation for a chemical reaction in which the number of atoms for each element in the reaction and the total charge is  the same for both the reactants and the products.

Balanced chemical equation:

2Cl_2 (g) + C_2H_2 (g) → C_2H_2Cl_4(l)

In your case, 2 moles of chlorine gas are needed to produce 1 mole of tetrachloroethane, which implies that there's a 2:1 mole ratio between the two.

Calculating the mass of tetrachloroethane.

mC_2H_2Cl_4(l) = 15 g Cl_2 (g) X \frac{2 mol \;of \;Cl_2}{70 g \;Cl_2} X \frac{1 mol \;of \;C_2H_2Cl_4(l)}{2 mol \;Cl_2} X \frac{167.8 g \;C_2H_2Cl_4(l))}{1 mol \;C_2H_2Cl_4}

C_2H_2Cl_4(l) = 17.75 g

C_2H_2Cl_4(l) = 35.5 g

Hence, 35.5 g of tetrachloroethane is added if 15 gram of chlorine is used with excess C_2H_2

what is the molarity of an HCI solution if 25.0 ml of 0.185 M NaOH is required to neutralize 0.0200 L of HCI?​
butalik [34]

Answer:

Molarity of HCl solution = 0.25 M

Explanation:

Given data:

Volume of NaOH= V₁ = 25.0 mL (25/1000 = 0.025 L)

Molarity of NaOH solution=M₁ = 0.185 M

Volume of HCl solution = V₂ = 0.0200 L

Molarity of HCl solution =  M₂= ?

Solution:

M₁V₁   =  M₂V₂

0.185 M ×0.025 L =  M₂ × 0.0200 L

M₂  = 0.185 M ×0.025 L / 0.0200 L

M₂  = 0.005M.L /0.0200 L

M₂  =  0.25 M

The fluoride rinse in dental offices usually contains sodium fluoride. Sodium fluoride can be prepared from the reaction between
Bad White [126]

The chemical reaction in which number of atoms of each element present in the reactant side is equal to the number of atoms of that element in product side, such reactions are said to be a balanced chemical reaction.

The chemical symbol for sodium is Na.

The chemical symbol for fluorine gas is F_2.

The chemical symbol for sodium fluoride is NaF

The sodium fluoride is prepared from the reaction between sodium metal and fluorine gas can be written as:

Na (s)+F_2(g) \rightarrow NaF(s)

The above reaction is not balanced as the number of fluorine atoms are not same on reactant and product side. So, in order to balance the reaction we will multiply Na with 2 on reactant side and NaF with 2 on product side. Thus, the balanced reaction will be:

2Na (s)+F_2 (g)\rightarrow 2NaF(s)

Thus, the balanced chemical equation is 2Na (s)+F_2 (g)\rightarrow 2NaF(s).
