1.
2NaCl + Pb(CH3COO)2 → 2NaCH3COO + PbCl2
2.
K2SO4 + SrI2 → KI + SrSO4
3.
Cr(NO3)3 + Na3PO4 →CrPO4 + NaNO3
It becomes charged and is called an ion. Gaining an electron gives it a negative charge.
Traits are determined by alleles.
The volume of the flexible container that holds a sample of hydrogen gas at 153 kPa is 1.51L (option B).
<h3>How to calculate volume?</h3>
The volume of a substance can be calculated using the following formula:
P1V1 = P2V2
Where;
- P1 = initial pressure
- P2 = final pressure
- V1 = initial volume
- V2 = final volume
153 × 3 = 304 × V2
459 = 304V2
V2 = 459/304
V2 = 1.51L
Therefore, the volume of the flexible container that holds a sample of hydrogen gas at 153 kPa is 1.51L.
