Explanation:

Given that,

A calorimeter made from a can is used to measure the calories in a peanut.

During the experiment, the measured calories were 35% of the true/accepted value given by references

Suppose, the mass of peanut is 0.4 g and find the

We need to calculate the heat generated per gram of sample in calories

Using formula of heat generated

$q=\dfrac{q_{penut\ calorimeter}}{m_{peanut}}$

Put the value into the formula

$q=\dfrac{0.35}{0.4}$

$q=0.87\ g$

Hence, The heat generated per gram of sample in calories is 0.87 g

Answer: The correct answer is Option B.

Explanation:

There are 3 subatomic orbitals which are present in an atom:

1. Protons: These sub-atomic particles are positively charged and are found in the nucleus.

2. Electrons: These sub-atomic particles are negatively charged and are found in the orbitals around the nucleus.

3. Neutrons: These sub-atomic particles carry no charge and are known as electrically neutral species. These particles are found in the nucleus.

From the above information, the answer to this question is Option B.
