Question

At STP, a 50.-gram sample of H2O(l) and a 100.-gram sample of H2O(1) have

1. the same chemical properties

2. the same volume

3.different temperatures

4.different empirical formulas

Answer 1

Answer:

The same chemical properties

Explanation:

Different masses of water at the same temp and pressure will have different volumes and the same empirical formulas and the same chemical properties

Answer 2

At STP, a 50.-gram sample of H2O(l) and a 100.-gram sample of H2O(l) have  the same chemical properties.

The temperature, volume and other physical properties of a sample may vary with the mass of substance present.

However, the chemical properties of a substance do not change irrespective of the amount of substance present. Even the smallest mass of water still retains all the chemical properties of water.

Therefore, at STP, a 50.-gram sample of H2O(l) and a 100.-gram sample of H2O(l) have  the same chemical properties.
