Answer:
m(H₂O) = 97,2 g.n(H₂O) = m(H₂O) ÷ M(H₂O).n(H₂O) = 97,2 g ÷ 18
Explanation:
we have
work done (W)= force(F) × displacemen(s)
or, 80= F× 8
or, F= 10 N
therefore, 10 N force is required to lift the rock.
Explanation:
Matter can be categorized into substances and mixtures.
Matter is anything that has mass and occupies spaces.
Substances are distinct matter with the following properties:
- All parts are the same throughout i.e homogeneous
- Their composition is definite
- They cannot be easily separated or broken down into simpler substances by physical means
- Separation by physical means is not easy
- They have a unique set of physical properties.
Mixtures have the following properties:
- Their composition is indefinite i.e they consist of two or more elements and/or compounds in any proportion by mass
- Their constituents retains their identity
- They can easily be separated by physical means
- They have a broad range of physical properties.

Answer:
your answer will be between 16-17 moles
Explanation:
The combustion of butane is 2 C4H10 + 13 O2 = 8 CO2 + 10 H2O. Every two moles of C4H10 can produce 10 moles of water,
