Electrolyte solutions are substances that give ions when dissolved in water. <span>These solutions </span>conduct electricity<span> due to the mobility of the positive and negative ions, which are called cations and anions. Hope this answers the question. Have a nice day.</span>
7.) Carbon-14 is a radioactive isotope of carbon. The half-life of carbon-14 is approximately 5,730 years. The short half-life of carbon-14 means it cannot be used to date fossils that are allegedly extremely old, e.g. dinosaurs the evolution alleges lived millions of years ago. Levels of carbon-14 become difficult to measure and compare after about 50,000 years (between 8 and 9 half lives; where 1% of the original carbon-14 would remain undecayed).
8.)

The answer is A, I think.
A. the answer is decrease
Answer:
65.2L
Explanation:
Using the general gas equation;
PV = nRT
Where;
P = pressure (atm)
V = volume (Litres)
n = number of moles (mol)
R = gas law constant (0.0821 Latm/molK)
T = temperature (Kelvin)
According to the information provided in this question,
P = 1.631 atm
V = ?
n = 4.3 moles
T = 28°C = 28 + 273 = 301K
Using PV = nRT
V = nRT/P
V = 4.3 × 0.0821 × 301 ÷ 1.631
V = 106.26 ÷ 1.631
V = 65.15
Volume of the gas = 65.2L
