Explanation: Balance the reaction of KOH + H3PO4 = K3PO4 + H2O using this chemical equation balancer!
Answer:
11.3 g/mL.
Explanation:
- Density is a characteristic property of a substance.
- The density of a substance is the relationship between the mass of the substance and the volume it takes up.
<em>d = m/V,</em>
where, d is the density of the metal,
m is the mass of the metal (m = 12.475 g),
V is the volume that the metal takes up (V = 6.1 mL - 5.0 mL = 1.1 mL).
<em>∴ d = m/V =</em> (12.475 g)/(1.1 mL) = <em>11.34 g/mL ≅ 11.3 g/mL.</em>
<em>The significant figures has its rules in the calculations; the result has a significant figures to the lowest no. of significant figures (1.1 has two significant figures, while 12.475 has 5 significant figures), so the result should have only 2 significant figures.</em>

Answer:
it’s mass was greater than when it started
Explanation:
When a metal is coated with another metal, the plating metal deposits on the plated metal. Usually, the plating metal functions as the anode while the plated metal functions on the cathode. The anode metal is oxidized and reduced at the cathode and become deposited on the cathode material. This increases the mass of the cathode. Hence the mass of the silver/gold product is greater than the mass of silver at the beginning of the electroplating process.
