The balanced equation is Mg + 2AgNO₃ ⟶ Mg(NO₃)₂ + 2Ag

Step 1. Write the <em>unbalanced equation </em>

Mg + AgNO₃ ⟶ Mg(NO₃)₂ + Ag

Step 2. Start with the<em> most complicated-looking formula</em> [Mg(NO₃)₂] and balance its atoms.

Mg: Already balanced —1 atom each side.

N: We need 2 N on the left. Put a 2 in front of AgNO₃.

1Mg + 2AgNO₃ ⟶ 1Mg(NO₃)₂ + Ag

O: Already balanced —6 atom6 each side.

Step 3: Balance <em>Ag</em>

We have 2Ag on the left. We need 2Ag on the right.

1Mg + 2AgNO₃ ⟶ 1Mg(NO₃)₂ + 2Ag

The reaction of HCl with NaOH is represented by the equation HCl( aq) + NaOH( aq) ® NaCl( aq) + H 2O( l) What volume of 0.631 M

Darina [25.2K]

8.04 mL.

<h3>Explanation</h3>

How many moles of NaOH?

Note the unit:

$V = 15.8 \; \textbf{mL} = \dfrac{15.8}{1000}\;\textbf{L} = 0.0158 \; \text{L}$ .

$n = c\cdot V = 0.0158 \times0.321 = 0.00507\;\text{mol}$ .

How many moles of HCl?

As seen in the equation, HCl and NaOH reacts at a 1:1 ratio.

$n(\text{HCl}) = n(\text{NaOH}) = 0.00507\;\text{mol}$ .

How many mL of HCl?

$V = \dfrac{n}{c} =\dfrac{0.00507}{0.631} = 0.00804\;\text{L} = 0.00804\times 1000 \;\textbf{mL} = 8.04\;\text{mL}$ .

When an atom _______<br> an electron, it charge is negative .

nikitadnepr [17]

Answer:

Gains

Explanation:

If it gains an electron it causes the atom to become negative since electrons are negative and an overall charge of an atom is neutral. Therefore, it would become negative.

Hope this helps :)
