The correct answer that would best complete the given statement above is option B. Heat in a substance is an example of a kinetic energy. Kinetic energy is a kind of energy that is in motion. We can feel the kinetic energy of heat through their temperatures because heat is being transferred.

Answer: Option (B) is the correct answer.

Explanation:

When there will be flow of energy from one substance to another then it is defined as the heat.

Since, heat is responsible for the movement of particles of a substance. This means that more if the heat more will be the kinetic energy as kinetic energy is the energy obtained by particles of a substance due to their motion.

Also, kinetic energy is directly proportional to temperature.

K.E = $\frac{3}{2}kT$

So, more is the temperature of an object more will be heat transferred by it. Therefore, more will be its kinetic energy.

Thus, we can conclude that heat in a substance is an example of kinetic energy.

6. Identify the number of neutrons in one atom of silicon with an isotopic mass number of 28 amu.

Sholpan [36]

Explanation:

The number of neutrons in one atom of silicon with an isotopic mass number of 28amu is 14.

An atom is made up three fundamental sub-atomic particles which are:

Protons, neutron and electrons

Protons are the positively charged particles in an atom

Neutrons do not carry any charges

Electrons are the negatively charged particles.

In the nucleus of an atom, both protons and neutrons can be found. They are the massive particle in an atom.

The mass number of an atom = number of protons + number of neutrons

Number of neutrons = mass number - number of protons.

From the periodic table, we know that silicon has an atomic number of 14.

The atomic number is the number of protons in an atom:

Number of neutrons = 28 - 14 = 14amu

In the atom, we will have 14amu of neutrons in a silicon atom.

96.0 g. of a gas occupies 48.0 L at 700.0 mm Hg and 20.0 °C. What is its molecular weight?

g100num [7]

Answer:

I hope this helps 52.2 g/mol

Explanation:

1) Solve for the moles using PV = nRT:

n = PV / RT

n = [(700.0 mmHg / 760.0 mmHg atm¯1) (48.0 L)] / [(0.08206 L atm mol¯1 K¯1) (293.0 K)]

n = 1.8388 mol

2) Divide the grams given (96.0) by the moles just calculated above:

96.0 g / 1.8388 mol = 52.2 g/mol

Caclulate the pH of a solution with a hydrogen ion concentration of 1X10-7

LUCKY_DIMON [66]

Answer:

The pH of the solution is 7.00 .

Explanation:

The pH gives us an idea of the acidity or basicity of a solution. More precisely, it indicates the concentration of H30 + ions present in said solution. The pH scale ranges from 0 to 14: from 0 to 7 corresponds to acid solutions, 7 neutral solutions and between 7 and 14 basic solutions. It is calculated as:

pH = -log (H30 +)

pH= -log (1x10^-7)
