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.
What are SMRs?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.

Please, I really need help. I don't know what to do...
Answer:
Explanation:
Firstly, let's define what ground and excited state electronic configuration.
Ground state electronic configuration is when the electrons of the atom are in there lowest possible energy level while excited state electronic configuration is when electron(s) have moved to a higher energy level. Examples of these are provided in the options
a. 1s²2s²2p⁴ - This is a ground state electronic configuration (of oxygen) because the electrons are in there lowest possible energy level.
b. This option is not displaying (it is displaying something like an image that isn't loading)
c. 1s²2s²2p³3s¹ - We can see from this that an electron jumped from 2p energy level to 3s (p energy level ought to be completely filled with 6 electrons before another electron moves to the next energy level) meaning the electron is in it's excited state thus this is an excited state electronic configuration (of oxygen).
d. 1s²2s¹2p² - We can see from this also that an electron jumped from the 2s energy level to the 2p energy level (making it 2p² instead of 2p¹ in the ground state). The 2s energy level should ordinarily have 2 electrons. Thus, this is an excited state electronic configuration (of boron).
e. 1s²2s²sp¹ - This is a ground state electronic configuration (of boron) since all the electrons are in there lowest possible energy level.
f. 1s²2s³ - This configuration is impossible because the s energy level should only contain a maximum of 2 electrons, thus impossible to have 3 electrons in the s energy level
How many atoms are present in 1.4 grams of aluminum?
Answer: 3.2x10^23
Explanation:
Start by finding the molar mass of aluminum.
Then turn grams into moles by dividing grams of substance by molar mass. 1.4g÷26.98g
Then multiply that by 6.022x10^23 atoms. 0.0519x6.022x10^23

law of conservation of matter
Answer:
Matter says that the amount of matter stays the same, even when matter changes form. Sometimes it may seem that matter disappears during a science experiment, but this law tells us that matter cannot magically appear or disappear, it simply changes from one form to another.
Explanation:
brainliest?
Answer: Hope this helps:)
The Law of Conservation of Mass dates from Antoine Lavoisier's 1789 discovery that mass is neither created nor destroyed in chemical reactions. In other words, the mass of any one element at the beginning of a reaction will equal the mass of that element at the end of the reaction. The law of conservation of matter states that in any given system that is closed to the transfer of matter, the amount of matter in the system stays constant. The law of conservation of matter says that in chemical reactions, the total mass of the products must equal the total mass of the reactants. French chemist A. Lavoisier laid the foundation to the scientific investigation of matter by describing that substances react by following certain laws. These laws are called the laws of chemical combination. Matter says that the amount of matter stays the same, even when matter changes form. Sometimes it may seem that matter disappears during a science experiment, but this law tells us that matter cannot magically appear or disappear, it simply changes from one form to another. Matter can change form through physical and chemical changes, but through any of these changes, the matter is conserved. The same amount of matter exists before and after the change—none is created or destroyed. This concept is called the Law of Conservation of Mass.

This table shows the pH values of different solutions. A 2-column table with 4 rows. The first column labeled solution has entries W, X, Y, Z. The second column labeled p H has entries 6, 5, 1, 3. Which ranks the solutions from the strongest to weakest acid? W X Y Z Y W X Z W X Z Y Y Z X W
Answer:
D- Y -Z -X -W
:)
The solution with lowest pH are more acidic and those with higher pH values are basic. The given solutions can be ranked from the strongest to weakest acid as Y Z X W.
What is pH?pH of a solution is the measure of its H+ ion concentration. Mathematically it is the negative logarithm of H+ ion concentration of the solution. The acidic solutions contains more H+ ions.
A pH value of 7 represents a neutral solution. The pH above 7 is basic solution and a solution with pH below 7 is acidic in nature. A pH scale can be used to measure the range.
The pH of 1 and 3 indicates strong acidic solutions and 5 and 6 are weakly acidic . The lowest value of pH indicates highest acidity. Therefore, the correct order is Y Z X W.

Calculate the number of protons and neutrons for ²⁴Mg and 88Sr.
Answer:
12 protons and 12 neutrons are present in Mg and
38 protons and 50 neutrons are present in Sr
Explanation:
Answer:
For ²⁴Mg
1. Proton number = 12
2. Neutron number = 12
For ⁸⁸Sr:
1. Proton number = 38
2. Neutron number = 50
Explanation:
For ²⁴Mg:
1. Determination of the number of proton.
The atomic number of an element is simply defined as the number protons in the atom of the element. The atomic number of ²⁴Mg is 12 since no two elements have the same atomic number.
Atomic number = 12
Proton number = Atomic number
Proton number = 12
2. Determination of the Neutron number.
Mass number = 24
Proton number = 12
Neutron number =?
Mass number = Proton + Neutron
24 = 12 + Neutron
Collect like terms
Neutron = 24 – 12
Neutron number = 12
For ⁸⁸Sr:
1. Determination of the number of proton.
The atomic number of ⁸⁸Sr is 38.
Atomic number = 38
Proton number = Atomic number
Proton number = 38
2. Determination of the Neutron number.
Mass number = 88
Proton number = 38
Neutron number =?
Mass number = Proton + Neutron
88 = 38 + Neutron
Collect like terms
Neutron = 88 – 38
Neutron number = 50

What is the mass of silicon when there are 1.8 x 10^21 atoms of silicon?
Answer:
Mass = 0.084 g
Explanation:
Given data:
Mass of silicon = ?
Number of atoms of silicon = 1.8 × 10²¹ atom
Solution:
Avogadro number:
The given problem will solve by using Avogadro number.
It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance. The number 6.022 × 10²³ is called Avogadro number.
1 mole = 6.022 × 10²³ atoms
1.8 × 10²¹ atom × 1 mole / 6.022 × 10²³ atoms
0.299× 10⁻² mol
0.00299 mol
Mass of silicon:
Mass = number of moles × molar mass
Mass = 0.00299 mol × 28.1 g/mol
