<u>Answer:</u>
<em>4.5 L water we have in litres (L).</em>
<em><u></u></em>
<u>Explanation:</u>
where
= Final T - Initial T
Q is the heat energy in calories
c is the specific heat capacity (for water 1.0 cal/(g℃))
m is the mass of water
Plugging in the values
So,
Volume of water = mass/density
=4.5 L (Answer)
A change in temperature is a sign that a chemical reaction has occurred. This occurs in an endothermic reaction. An endothermic process is any process which requires or absorbs energy from its surroundings, usually in the form of heat. It may be a chemical process, such as dissolving ammonium nitrate in water, or simply the melting of ice cubes.
Hopefully im not too late :/

Compound
Explanation:
-compound is a chemical substance composed of many identical molecules composed of atoms from more than one element held together by chemical bonds.
Answer:
The answer to your question is 1.25 moles of C
Explanation:
Reaction
5C + 2SO₂ ⇒ CS₂ + 4CO
Check that the reaction is balanced
Reactant Element Product
5 C 5
2 S 2
4 O 4
Use proportions to find the moles of C needed.
5 moles of C ----------------- 2 moles of SO₂
x moles of C ---------------- 0.500 moles of SO₂
x = (0.500 x 5) / 2
x = 1.25 moles of C
