Explanation:

Magma convection is the primary driving mechanism by which geothermal energy is brought to the earth.

Geothermal energy is energy from deep within earth has been brought close to crustal levels.

They are usually sourced from areas in which a body of magma is appreciably close to the surface or where the mantle is close up.

Mantle convection is movement of magma within the region of the earth's mantle.
In this process, hot magma rises up close to the surface and cold ones sinks further deep into the mantle.
As hot magma rises in the mantle, it is brought close to the surface and crustal levels.
Where the crust is thin, the heat from the ensuing magma can be felt more close up
Cracks in the overlying lithosphere can bring these magma up ensuring a continuous supply of this hot mantle materials.

How many grams of sodium acetate are in solution in the third beaker?

Kipish [7]

Answer:

46g of sodium acetate.

Explanation:

The data is: Precipitation from a supersaturated sodium acetate solution. The solution on the left was formed by dissolving 156g of the salt in 100 mL of water at 100°C and then slowly cooling it to 20°C. Because the solubility of sodium acetate in water at 20°C is 46g per 100mL of water, the solution is supersaturated. Addition of a sodium acetate crystal causes the excess solute to crystallize from solution.

The third solution is the result of the equilibrium in the solution at 20°C. As the maximum quantity that water can dissolve of sodium acetate at this temperature is 46g per 100mL and the solution has 100mL there are 46g of sodium acetate in solution. The other sodium acetate precipitate because of decreasing of temperature.

I hope it helps!

Convert 8.50 moles Ca to atoms

Wewaii [24]

8.50 moles is equal to 5.1187×10²⁴ atoms of Ca.

Explanation:

We have to multiply the moles of Ca by the Avogadro's number:

= 6.022×10²³

So the number of atoms:

= 8.5 moles × 6.022×10²³atoms / mol

= 5.1187×10²⁴ atoms

Hence the 8.50 moles is equal to 5.1187×10²⁴ atoms of Ca.

A scientist wants to make a solution of tribasic sodium phosphate, Na3PO4, for a laboratory experiment. How many grams of Na3PO4

Anna71 [15]

Answer:

31.652g of Na3PO4

Explanation:

We'll begin by calculating the molarity of Na3PO4 solution. This can be achieved as shown below:

Na3PO4 will dessicate in solution as follow:

Na3PO4(aq) —> 3Na+(aq) + PO4³¯(aq)

From the balanced equation above,

1 mole of Na3PO4 produce 3 moles of sodium ion, Na+.

Therefore, xM Na3PO4 will produce 1.10M sodium ion, Na+ i.e

xM Na3PO4 = (1.10 x 1)/3

xM Na3PO4 = 0.367M

Therefore, the molarity of Na3PO4 is 0.367M.

Next, we shall determine the number of mole of Na3PO4 in the solution. This is illustrated below:

Molarity of Na3PO4 = 0.367M

Volume = 525mL = 525/1000 = 0.525L

Mole of Na3PO4 =..?

Molarity = mole /Volume

0.367 = mole /0.525

Cross multiply

Mole of Na3PO4 = 0.367 x 0.525

Mole of Na3PO4 = 0.193 mole.

Finally, we shall convert 0.193 mole of Na3PO4 to grams. This is illustrated below:

Molar mass of Na3PO4 = (23x3) + 31 + (16x4) = 164g/mol

Mole of Na3PO4 = 0.193 mole

Mass of Na3PO4 =.?

Mass = mole x molar mass

Mass of Na3PO4 = 0.193 x 164

Mass of Na3PO4 = 31.652g

Therefore, 31.652g of Na3PO4 is needed to prepare the solution.
