Answer:
The answer you have selected is correct
Explanation:
The ingredient's molecules would be more free and move faster, then the phase would change to liquid from solid.
<u>Explanation</u>:
- This task seeks to examine the knowledge of the kinetic phase and characteristics of matters.
- Here we see the chef described that the ingredient's molecules are moving in place – solid.
- On the advent of causing the ingredient to change phase by transferring energy into it – the ingredient's molecules would be more free and move faster, then the phase would change to liquid from solid.

Answer:
Answer and Explanation: In this reaction ammonium sulfate reacts with potassium hydroxide to give aqueous potassium sulfate, gaseous ammonia, and liquid water as the products. This is essentially an acid-base reaction where the ammonium ion is donating a hydrogen ion to the hydroxide ion from the potassium hydroxide.

Answer:
0.092M
Explanation:
Molarity of glucose solution = number of moles ÷ volume
According to this question, 12.5g of glucose (C6H12O6) is dissolved in enough water to make 750mL of solution.
Molar mass of glucose (C6H12O6) = 12(6) + 1(12) + 16(6)
= 72 + 12 + 96
= 180g/mol
mole = mass/molar mass
mole = 12.5/180
mole = 0.069mol
Volume of solution = 750mL = 750/1000 = 0.750L
Hence, molarity = n/V
Molarity = 0.069 ÷ 0.750
Molarity = 0.092M
