False- water has a high specific heat, so it does not change temperature as easily.
Answer: The correct answer is Option B.
Explanation:
To calculate the number of moles, we use the formula:
Molar mass of iron = 55.8 g/mol
Given mass of iron = 558.8
Putting values in above equation, we get:
For the given chemical equation:
By Stoichiometry,
4 moles of Iron produces 2 moles of Iron(III) oxide
So, 1 mole of Ion will produce = 
= 0.5 mole of Iron (III) oxide.
Hence, the correct answer is Option B.
Answer:
It's a very good subject!
Answer: b- it is always a substance
Explanation: matter can be any liquid, gas, or solid that takes up space so the answer cannot be C or D. For answer number A to be true, you would have to remove the word more, because matter just has mass and takes up space it does not have "more mass"
Answer:B
Explanation: Because you know how the is potential energy and then there is kinetic energy yeah those have to do with movement like a roller coaster
