How many grams of sodium oxide can be synthesized from 17.4 g of sodium? assume that more than enough oxygen is present. the bal

Tatiana [17]

Equation is as follow,

 4 Na (s) + O₂ (g) → 2Na₂O (s)

According to equation,

91.92 g (4 moles) of Na produces = 123.92 g (2 moles) of Na₂O
So,
17.4 g of Na will produce = X g of Na₂O

Solving for X,
X = (17.4 g × 123.92 g) ÷ 91.92 g

X = 23.45 g of Na₂O

What is the concentration of 60 mL of H3PO4 if it is neutralized by 225 mL of 2 M Ba(OH)2?

goldfiish [28.3K]

7.5 M is the concentration of 60 ml of H3PO4 if it is neutralized by 225 ml of 2 M Ba(OH)2.

Explanation:

Data given:

volume of phosphoric acid, Vacid =60 ml

volume of barium hydroxide, Vbase = 225 ml

molarity of barium hydroxide, Mbase = 2M

Molarity of phosphoric acid, Macid =?

the formula for titration is used as:

Macid x Vacid = Mbase x Vbase

rearranging the equation to get Macid

Macid = $\frac{Mbase x Vbase}{Vacid}$

Macid = $\frac{225 X 2}{60}$

Macid = 7.5 M

the concentration of the phosphoric acid is 7.5 M and the volume is 60 ml. Thus 7.5 M solution of phosphoric acid is used to neutralize the barium hydroxide solution of 2M.

Answer: The number to the left of AC should be 6.

Explanation: The balanced chemical reaction is one in which the number of atoms of each element on the reactant side must be equal to the number of atoms on product side.

The given equation $A_2B + DC_3 \rightarrow AC + D_2B_3$ is unbalanced as the atoms on the reactant side are not same as number of atoms on product side. This equation is called as skeletal equation.
