Which answer choice correctly describes the gas law and physical changes represented by the image?

skelet666 [1.2K]

Answer:

<h2>A. The image shows Boyle's Law because volume decreases as pressure increases.</h2>

Explanation:

According to Boyle's Law, at constant temperature, pressure and volume have inverse relation that is as pressure would increase, volume would decrease.

According to Charles Law, at constant pressure, the volume is directly proportional to temperature.

According to the given graph and diagram, the temperature is constant and volume and pressure have inverse relation.

Thus, option A is correct.

A 0.100-l sample of an unknown hno3 solution required 32.9 ml of 0.200 m ba(oh)2 for complete neutralization. what was the conce

ddd [48]

The reaction between HNO3 and Ba(OH)2 is given by the equation below;
2HNO3 + Ba(OH)2 = Ba(NO3)2 + 2H2O
Moles of Barium hydroxide used;
= 0.200 × 0.039 l
= 0.0078 Moles
The mole ratio of HNO3 and Ba(OH)2 is 2: 1
Therefore; moles of nitric acid used will be;
= 0.0078 ×2 = 0.0156 moles
But; 0.0156 moles are equal to a volume of 0.10
The concentration of Nitric acid will be;
= (0.0156 × 1)/0.1
= 0.156 M
