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.
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.

PLZ FASTLEY ANSWER The images show two metamorphic rock samples.
Left: light colored rock with coarse texture. Right: red and white rock with rounded grains and coarse texture.
Which statement accurately describes these rocks?
Both rocks are non-foliated.
Neither rock has randomly arranged grains.
Both rocks formed at Earth’s surface.
Neither rock formed through extreme heat or pressure.
Answer:
a
Explanation:
From the given images, it is clear that both rocks are non-foliated rocks because they don't have distinct repetitive layers. Hence option a is correct.
What are metamorphic rocks?Metamorphic rocks are formed through intense pressure and heating from the sedimentary or igneous rocks. Sometime the change n heat or pressure make the metamorphic rocks gets foliated.
Foliation occurs when pressure forces flat or elongate minerals within a rock to align. These rocks form a platy or sheet-like structure that reflects the pressure direction. There is no platy or sheet-like structure in non-foliated metamorphic rocks.
Non-foliated rocks can be created in a variety of ways. Some rocks, like limestone, are composed of minerals that are not flat or elongate. Therefore, the given rocks are non-foliated.

10.0 grams of a gas occupies 12.5 liters at a pressure of 42.0 mm Hg. What is the volume when the pressure has increased to 75.0 mm Hg? 6.72 L 7.00 L 22.3 L 0.143 L
Answer: 7.00 L
Explanation:
Boyle's Law: This law states that pressure is inversely proportional to the volume of the gas at constant temperature and number of moles.
[tex]P\propto \frac{1}{V}[/tex] (At constant temperature and number of moles)
[tex]P_1V_1=P_2V_2[/tex]
where,
[tex]P_1[/tex] = initial pressure of gas = 42.0 mm Hg
[tex]P_2[/tex] = final pressure of gas = 75.0 mm Hg
[tex]V_1[/tex] = initial volume of gas = 12.5 L
[tex]V_2[/tex] = final volume of gas = ?
[tex]42.0\times 12.5=75.0\times V_2[/tex]
[tex]V_2=7.00L[/tex]
Therefore, the volume when the pressure has increased to 75.0 mm Hg is 7.00 L

What is the mass of hydrogen produced when 8.0 g of sodium
reacts with an excess of water to produce hydrogen and sodium
hydroxide? The equation is given.
2 Na + 2 H2O → 2NaOH + H2
Answer:
Mass = 0.35 g
Explanation:
Given data:
Mass of sodium = 8.0 g
Mass of hydrogen produced = ?
Solution:
Chemical equation:
2Na + 2H₂O → 2NaOH + H₂
Number of moles of sodium:
Number of moles = mass/molar mass
Number of moles = 8.0 g/ 23 g/mol
Number of moles = 0.35 mol
now we will compare the moles of sodium and hydrogen
Na : H₂
2 : 1
0.35 : 1/2×0.35 = 0.175 mol
Mass of hydrogen:
Mass = number of moles × molar mass
Mass = 0.175 mol × 2 g/mol
Mass = 0.35 g

How do the particies in a liquid create surface
tension?
It's been a while since I've taken Chemistry but here's what I know:
There are small, weak bonds that form between water molecules. These bonds make it so liquid molecules (water, in this example) cannot move as freely as a gas, but their bonds aren't nearly as strong as a solid. The bonds are formed when a hydrogen atom is attracted to an oxygen atom (because they have an opposite charge). This bond plus the gas molecules hitting the water causes surface tension.
(Let me know if this is wrong and I hope you have a lovely day!!)
Airplanes typically fly at an altitude of about 10,000 meters. At this altitude the atmospheric pressure is significantly less than it is at sea-level. Because of this, airplane cabins must be pressurized so that the people on board can continue to get enough oxygen. If a typical 747 has a volume of 28,000 m3 and is filled with air at 101.3 kPa on the ground, what is the new volume of air inside when the cabin is pressurized to 75 kPa once it is in flight?
Answer:
37,818.67 m3
Explanation:
The pressure a gas will exert on a container is inversely proportional to the volume of the gas. According to Boyle's law, at a constant temperature, the pressure of a gas is inversely proportional to its volume. The law can be mathematically represented thus:
P1V1 = P2V2
In this case, P1 = 101.3 kPa, V1 = 28,000 m3, P2 = 75 kPa, V2 = ?
V2 = P1V1/P2
= 101.3 x 28,000/75
= 37,818.67 m3
Hence, the new volume of the air inside the cabin after pressurizing would be 37,818.67 m3.
In which material would the particles be closest together?
O Syrup
O Brick
O Air
O Water
Answer:
Brick
Explanation:
The distance between particles is best determined by density. So, to find which material has the most compacted particles, we need to find which material has the highest density. Solids will always have the highest densities, so Brick would have the particles that are closest together.

Using the electronegativity chart below, determine which compound would have the highest polarization
A. Li-O
B. B-F
C. H-CI
D. Be-Br
Answer:
A. Li-O
Explanation:
The highest polarization will occur between the atoms of Li-O because they have the most electronegativity difference between them.
Polarization occurs when there is a separation of charge between the atoms of heteronuclear molecules.
The electronegativity gives the tendency for an atom to attract the electrons within the bond pair to itself.
To know the atom with most polarization, it has to be one with highest electronegativity difference. Li and O have the highest difference. Also, since the bond is between a metal and non-metal, it is obviously the most polarized.
what's the molar mass of Li3p
Answer:
51.79g Li₃P.
Explanation:
Li has a molar mass of 6.94 g (since there are 3, you multiply it 3 times) and P has a molar mass of 30.97 g. 6.94(3) + 30.97 = 51.79g.
