Answer:

The SMRs can adjust their energy output using coolants and control rods.

Power plants can be built to fit locations with less demand or less space.

Explanation:

I think that it is but I am not sure.

Power plants can be built to fit locations with less demand or less space. The SMRs can adjust their energy output using coolants and control rods. The correct options are B and D.

A wireless communications technology that competes with traditional cellular services. The base station equipment supplier is the transmitter licensee in an SMR system.

Power plants can be built to accommodate locations with low demand or limited space. Coolants and control rods allow SMRs to adjust their energy output.

These advanced reactors, which are expected to range in size from tens to hundreds of megawatts, can be used for power generation, process heat, desalination, or other industrial applications.

Light water or other non-light water coolants, such as a gas, liquid metal, or molten salt, may be used as a coolant in SMR designs.

Thus, B and D are correct options.

detail is given below.

Explanation:

The charged particles of nucleus are protons while neutrons are neutral having no charge.

We know that an atom consist of electrons, protons and neutrons. Neutrons and protons are present inside the nucleus while electrons are present out side the nucleus. Electron has a negative charge and is written as e⁻. The mass of electron is 9.10938356×10⁻³¹ Kg . While mass of proton and neutron is 1.672623×10⁻²⁷Kg and 1.674929×10⁻²⁷ Kg respectively.

Symbol of proton= P⁺  

Symbol of neutron= n⁰  

The number of electron or number of protons are called atomic number while mass number of an atom is sum of protons and neutrons.

one proton contribute 1 amu to the total weight. There are 20 protons and 20 neutrons in Ca thus its atomic mass is 40 amu.

While the atomic number is 20.

Explanation:

Explanation:

Weathering occurs one of three ways: through physical processes such as freezing and thawing, because of live organisms whose roots break rocks or through chemical processes that occur when carbon dioxide in the soil and air and mixes with water and specific minerals in rocks to form a weak acid that reduces rocks into silt, soil and sediment.

Chemical weathering typically increases as temperatures rise and rain falls, which means rocks in hot and wet climates experience faster rates of chemical weathering than do rocks in cold, dry climates.

Answer:

90.4Kg

Explanation:

The energy required= latent heat of vaporization

Latent heat of vaporization of water= 2260 KJ/Kg

Mass of water = 0.04 Kg

Heat required= 0.04Kg× 2260 KJ/Kg

Heat required= 90.4Kg

Answer: The minimum number of kilo Joules needed is 90.4KJ.

Explanation:

The energy required= latent heat of vaporization.

Latent heat of vaporization of water= 2260 KJ/Kg

Mass of water = 0.04 Kg

Heat required= 0.04Kg× 2260 KJ/Kg

Heat required= 90.4KJ.

Answer:

Oxygen.

Explanation:

Oxygen is a chemical element that aides in the burning of materials and it is needed for humans to breathe.

Cellular respiration can be defined as a series of metabolic reactions that typically occur in cells so as to produce energy in the form of adenosine triphosphate (ATP). During cellular respiration, high energy intermediates are created that can then be oxidized to make adenosine triphosphate (ATP). Therefore, the intermediary products are produced at the glycolysis and citric acid cycle stage through the breathing of oxygen used to obtain energy from the food ingested.

Hence, all cells in living organisms require oxygen and glucose to release energy.

Answer: 3.613x10^24

Explanation: Avogadro’s number represents the number of atoms in one mole of substance: 6.022x10^23 atoms/mole. Multiplying the number of moles by this number reveals that, in this sample, 3.613x10^24 atoms of methane are present.

Answer: A

Explanation: When using dimensional analysis, always put similar unit-ed numbers diagnolly from each other so they 'cross out'

For example, If you had 1 mol of gold and you wanted to convert it to grams using gold's molar mass, 196.97 g/mol, it would look like this:

Start with the given number over nothing:

[tex]\frac{1 mol Au}{} *\frac{ }{ }[/tex]

Then add your conversion, in this case the molar mass, with the MOLES on the BOTTOM, so they are diagnol with the 1 mol of Au

[tex]\frac{1 mol Au}{ } *\frac{196.7 g Au}{1 mol}[/tex]

Always have the top right in your dimensional analysis be in the units that you are solving for. In this case, we went from moles to grams, so grams is in the top right.

Hope this helps!

Also, 6.02 x 10²³ is otherwise known as avogadros number- it is used when you are converting something from moles to molecules (or particles). For example, if instead we were going from moles of gold to molecules of gold, our dimensional analysis would look like this:

[tex]\frac{1 mol Au}{ } *\frac{6.02 x 10^2^3 molecules Au}{1 mol}[/tex]

Answer:

0.84 moles of oxygen are required.

Explanation:

Given data:

Mass of CO₂ produced = 37.15 g

Number of moles of oxygen = ?

Solution:

Chemical equation:

C + O₂     →     CO₂

Number of moles of  CO₂:

Number of moles = mass/molar mass

Number of moles = 37.15 g/ 44 g/mol

Number of moles = 0.84 mol

Now we will compare the moles of oxygen and carbon dioxide.

                          CO₂         :       O₂  

                              1           :         1

                            0.84       :       0.84

0.84 moles of oxygen are required.
