The answer is covalent bond!
It will sink because water has a density of 1. and 1.1 is greater than 1 which means that the object is denser than the water so it will cause it to sink
The temperature change on a 150g sample of mercury with specific heat of 0.0330 Cag°C, If 480 cal of heat is added to it is 96.9°C.
<h3>How to calculate temperature change?</h3>
The temperature change of a substance can be calculated using the following formula:
Q = m × c × ∆T
Where;
- Q = quantity of heat absorbed or released
- m = mass of substance
- c = specific heat capacity
- ∆T = change in temperature
480 = 150 × 0.033 × ∆T
480 = 4.95∆T
∆T = 96.9°C.
Therefore, the temperature change on a 150g sample of mercury with specific heat of 0.0330 Cag°C, If 480 cal of heat is added to it is 96.9°C.

Carbon monoxide (CO) is the name
<u>Answer:</u> The concentration of acetic acid in the vinegar is
<u>Explanation:</u>
To calculate the pH of the solution, we use the equation:
We are given:
pH = 2.95
Putting values in above equation, we get:
The chemical equation for the ionization of acetic acid follows:
The expression of for above equation follows:
We are given:
Putting values in above expression, we get:
So, the concentration of acetic acid =
Hence, the concentration of acetic acid in the vinegar is
