Answer: C, 146
Explanation:
NaCl has a molar mass of 58.44 g/mol.
To change moles to g, we do:
2.50 moles × 58.44 g/mol = 146.1 g, so C
Answer:
shivering is a natural bodily response, the body is trying to heat itself up by moving around.
71.8 g of iron (III) oxide (Fe₂O₃) were produced from 3 moles of magnesium oxide (MgO).
Explanation:
We have the following chemical reaction:
2 FeCl₃ + 3 MgO → Fe₂O₃ + 3 MgCl₂
We see from the chemical reaction that 3 moles of magnesium oxide (MgO) will produce 1 mole of iron (III) oxide (Fe₂O₃).
number of moles = mass / molar weight
mass = number of moles × molar weight
mass of Fe₂O₃ = 1 × 71.8 = 71.8 g

<h2>The difference between matter, mass, and volume is that:</h2>
<u>Matter</u> is a physical substance which can be touched, seen, smelled, and sometimes heard. It comes in different states: liquid, solid, gas, and plasma.
<u>Mass</u> is the measure of how much <u>matter</u> is in an object.
<u>Volume</u> is the measure of how much space is inside of a 3D object.
