Answer the correct answer for the question is option a Increase in temperature of water.
Explanation- When the temperature of water is increased the energy of water is increased at molecular level, this increased energy causes vibration between the hot water molecules bit faster than in normal water which also allows the sugar molecules to vibrate and associate with water at molecular level as it gets more space between the molecules.
Hence this action would make sugar more soluble in water.
Answer:
it is just because of the weather because that's how it usually is in Arizona

Answer:
3.5 mol KClO3
Explanation:
Given 3.50 moles of KCl as the target amount in the problem, used the coefficient of the balanced chemical reaction involved to determine the number of moles of potassium perchlorate needed.
x mole of KClO3 = 3.5 mol KCl x [(2 mol KCl)/ (2 mol KClO3)] = 3.5 mol KClO3
x mole of KClO3 = 3.5 mol KClO3
Answer:
See below.
Explanation:
The mass of octane in the sample of gasoline is 0.02851 * 482.6 = 13.759 g of octane.
The balanced equation is:
2C8H18(l) + 25O2(g) ----> 16CO2(g) + 18H2O(g)
From the equation, using atomic masses:
228.29 g of octane forms 704 g of CO2 and 324.3 g of H2O
So the mass of CO2 formed from the combustion of 13.759 g of octane = (704 * 13.759) / 228.29
= 42.43 g of CO2.
Amount of water = 324.3 * 13.759) / 228.29
= 19.55 g of H2O.
