<h2>Answer:</h2>

Random error

<h2>Explanation:</h2>

If the volume of the sample is determined first then there can be a random error occur. Because volume can change during the process so it should be measured first.

<span>If the volume of a sample is determined first, you would have a 'random error'. The error will still be present, but its magnitude will be such a small fraction of the value that it will not be detected, and cause problems for later calculations.</span>

The table shows the amount of radioactive element remaining in a sample over a period of time.
harkovskaia [24]

1. The half-life of the element is 22 years

2. The time taken for 308 g of the sample to decay to 4.8125 g is 132 years

<h3>Definition of half-life </h3>

Half-life is simply defined as the time taken for half of a material to decay.

<h3>1. How to determine the half-life </h3>
  • Original amount (N₀) = 45 g
  • Half of the original amount = 45 / 2 = 22.5 g

From the diagram, the time for 22.5 g is 22 years.

Thus, the half-life of the element is 22 years

<h3>2. How to determine the time </h3><h3>i. Determination of the number of half-lives </h3>
  • Original amount (N₀) = 308 g
  • Amount remaining (N) = 4.8125 g
  • Number of half-lives (n) =?

2ⁿ = N₀ / N

2ⁿ = 308 / 4.8125

2ⁿ = 64

2ⁿ = 2⁶

n = 6

<h3>ii. Determination of the time </h3>
  • Number of half-lives (n) = 6
  • Half-life (t½) = 22 years
  • Time (t) =?

t = n × t½

t = 6 × 22

t = 132 years

Molecules with ____________ bonds between their components will ____________ (fall apart) in water, releasing charged particles
Musya8 [376]

Molecules with ionic bonds between their components will dissociate (fall apart) in water, releasing charged particles called ions.<span>
<span>When the number of protons and electrons are not equal, ion is formed. There are two types of ions, Cations and anions. Cations are the positively charged ions and when an atom gains electron, Cation is formed. Anions are negatively charged ions and when an atom loses electrons, anion is formed.</span></span>
