Answer:

1. Both

2. Acid

3. Acid

4. Base

5. Acid

6. Neither

7. Neither

8. Base

9. Acid

Explanation:

In Chemistry, a chemical compound can be either a base or an acid.

An acid reacts with metals to produce bubbles of hydrogen gas and it also reacts with carbonates while a base feels slimy to the touch. They both can change the color of a litmus paper.

Base has a sour taste while acids have a bitter taste (please do not use this characteristic to test for an acid in the laboratory)

The density of liquid mercury is 13.6 g/mL. What is its density in units of ? (2.54 cm = 1 in., 2.205 lb = 1 kg)
nalin [4]

Correct question

The density of liquid mercury is 13.6 g/mL. What is its density in units of lb/in​3​? (2.5 cm = 1 in., 2.205 lbs= 1 kg., 1000 g =1 kg, 1 mL = 1 cm³)

Answer:

\rho0.4916\ lb/in^3

Explanation:

Given that;-

The density = 13.6 g/mL

Also, 1 kg = 2.205 lb

1 kg = 1000 g

So, 1000 g = 2.205 lb

1 g = 0.002205 lb

Also,

1 in = 2.54 cm

1 in³ = 16.39 cm³

1 cm³ = 1 mL

So,  1 in³ = 16.39 mL

1 mL = 0.061 in³

The expression for the calculation of density is shown below as:-

\rho=\frac{m}{V}

Thus,

\rho=\frac{13.6\ g}{1\ mL}=\frac{13.6\times 0.002205\ lb}{0.061\ in^3}=0.4916\ lb/in^3
