Explanation:
Hey there!
There is 1 mol of Ca atoms in 1 mol of CaSO₄
There is one atom of Ca in each molecule of CaSO₄, so in 6.022 x 10²³ molecules of CaSO⁴ there will be 6.022 x 10²³ atoms of Ca.
Hope this helps!
9.17 milliliters (mL) of the acid are needed to completely neutralize the base in this reaction.
<h3>What is a neutralization reaction</h3>
A neutralization reaction is a reaction between an acid and a base to produce a salt and water only.
The process of reacting given volume of acids or bases to determine the concentration or volume of either the acid or base required for neutralization is known as titration in volumetric analysis.
The formula to determine the volume of the acid required is given below:
where 
is the volume of acid required
Concentration of base, Cb = (3.51/74)/0.75 = 0.063 M
Vb = 50. 0 mL
Ca = 0.229 M
Na = 2
Nb = 3
Va = (0.063 * 50 * 2)/(0.229 * 3)
Va = 9.17 mL
In conclusion, the volume of the acid is determined from the concentration, volume and mole ratio of the reaction.

<u>Answer:</u> The correct answer is heat will flow from the boiling water into the frozen metal.
<u>Explanation:</u>
According to the law of conservation of energy, energy cannot be destroyed nor created but it can be transformed from 1 form to another form.
There are 3 processes of heat transfer:
- <u>Conduction:</u> This type of heat transfer occurs when there is direct contact between the two objects.
- <u>Convection:</u> This type of heat transfer occurs when there is a movement of fluid (liquid or gas) due to the movement of hot layers to the top and cold layers to the bottom which leads to convection currents.
- <u>Radiation:</u> This type of heat transfer occurs when there is a direct transfer of energy through space.
The heat moves from a hot surface to a cold surface to maintain equilibrium.
We are given:
A metal is placed in a freezer (cold object) and another metal is placed in an oven (hot object) and then both the metals are placed in boiling water.
Initially, the heat will flow from the boiling water (hot object) into the frozen metal (cold object) to maintain equilibrium
Hence, the correct answer is heat will flow from the boiling water into the frozen metal.
Answer:
Seafloor spreading
Explanation:
Seafloor spreading is a geologic process in which tectonic plates—large slabs of Earth's lithosphere—split apart from each other.
Seafloor spreading and other tectonic activity processes are the result of mantle convection. Mantle convection is the slow, churning motion of Earth’s mantle. Convection currents carry heat from the lower mantle and core to the lithosphere. Convection currents also “recycle” lithospheric materials back to the mantle.
Seafloor spreading occurs at divergent plate boundaries. As tectonic plates slowly move away from each other, heat from the mantle’s convection currents makes the crust more plastic and less dense. The less-dense material rises, often forming a mountain or elevated area of the seafloor.
Eventually, the crust cracks. Hot magma fueled by mantle convection bubbles up to fill these fractures and spills onto the crust. This bubbled-up magma is cooled by frigid seawater to form igneous rock. This rock (basalt) becomes a new part of Earth’s crust.
