The answer is A! Let me know if I was correct
Gas
Kinetic energy is the energy an object has due to its motion. The faster particles move, the more kinetic energy they have. Solid objects have the least kinetic energy because their particles vibrate in place. Gases have the most kinetic energy because their particles move very quickly.
Answer:
Hydrolysis is any chemical reaction in which a molecule of water ruptures one or more chemical bonds.
Explanation:
Example:
Dissolving a salt of a weak acid or base in water is an example of a hydrolysis.
Answer:
357 g of the transition metal are present in 630 grams of the compound of the transition metal and iodine
Explanation:
In any sample of the compound, the percentage by mass of the transition metal is 56.7%. This means that for a 100 g sample of the compound, 56.7 g is the metal while the remaining mass, 43.3 g is iodine.
Given mass of sample compound = 630 g
Calculating the mass of iodine present involves multiplying the percentage by mass composition of the metal by the mass of the given sample;
56.7 % = 56.7/100 = 0.567
Mass of transition metal = 0.567 * 630 = 357.21 g
Therefore, the mass of the transition metal present in 630 g of the compound is approximately 357 g
