C is not an example.
explanation: Mass is a physical property as the law of conservation of mass states mass is neither created nor destroyed in a chemical reaction or physical transformation. Chemical reactions are a change in the molecular structure of the product.
Answer:
103.4 moles of hydrogen
Explanation:
Given data:
Moles of C₁₂H₂₂O₁₁ = 4.70 mol
Number of moles of hydrogen present = ?
Solution:
one mole of C₁₂H₂₂O₁₁ contain 22 moles of hydrogen. Thus in order to determine total number of moles in 4.70 moles of C₁₂H₂₂O₁₁ we will multiply the 22 moles of hydrogen with 4.70 moles of C₁₂H₂₂O₁₁.
1 mole of C₁₂H₂₂O₁₁ = 22 moles of Hydrogen
4.70 × 22 moles
103.4 moles of hydrogen

Answer:
Intensive
Explanation:
The electrical conductivity of a wire depends on its composition, not the length of the wire.
Hope this helps! If correct pls mark brainliest :)
Answer:
its endothermic .
because your using a cooling process instead of a heating process if it was a heating process it would be exothermic
