Answer:
Both the identity and the properties of a substance change.
Explanation:
During most chemical reactions, both the identity and the properties of substances changes. The chemical and physical properties of a substance often changes during this kind reaction.
A chemical change has the following properties:
- A new kind of substance forms.
- It is always accompanied by energy changes
- Involves a change in mass of the substance
- Considerable amount of energy is involved in this reaction.
- The process is irreversible
Answer:
54g of water
Explanation:
Based on the reaction, 1 mole of methane produce 2 moles of water.
To solve this question we must find the molar mass of methane in order to find the moles of methane added. With the moles of methane and the chemical equation we can find the moles of water produced and its mass:
<em>Molar mass CH₄:</em>
1C = 12g/mol*1
4H = 1g/mol*4
12g/mol + 4g/mol = 16g/mol
<em>Moles methane: </em>
24g CH₄ * (1mol / 16g) = 1.5 moles methane
<em>Moles water:</em>
1.5moles CH₄ * (2mol H₂O / 1mol CH₄) = 3.0moles H₂O
<em>Molar mass water:</em>
2H = 1g/mol*2
1O = 16g/mol*1
2g/mol + 16g/mol = 18g/mol
<em>Mass water:</em>
3.0moles H₂O * (18g / mol) =
<h3>54g of water</h3>
