What causes earthquakes? Be sure to use the words: Core Mantle Conduction Convection Density

Chemistry
1 answer:
IrinaVladis [17]3 years ago
8 0

Answer:

Explanation:

Earthquakes are normally caused by underground rock breaking along a fault line. The seismic waves that cause the earth to shake are caused by this sudden release of energy. The plates or blocks of rock begin to move during and after the earthquake, and they continue to move until they become trapped again. As fluid near the center heats up, convection currents develop within the Earth's mantle. Particles pass more quickly as the core heats the bottom layer of mantle material, lowering its density and allowing it to rise. The convection current is started by the growing material.

Calculate the density of CO2 at a pressure of 685.0 torr and 41.0°C . <br> R=0.0821 (L*atm)/(mol *K)
Keith_Richards [23]

T=41+273=314 k

M=(12)+(16×2)=44g/mol

d=PM/RT

d=685×44/0.0821×314

d=1169.15 g/L

What is the mass of solute in a 500 mL solution of 0.200 M
Fofino [41]

16.4 grams is the mass of solute in a 500 mL solution of 0.200 M .

sodium phosphate

Explanation:

Given data about sodium phosphate

atomic mass of Na3PO4 = 164 grams/mole

volume of the solution = 500 ml or 0.5 litres

molarity of sodium phosphate solution = 0.200 M

The formula for molarity will be used here to know the mass dissolved in the given volume of the solution:

The formula is

molarity = \frac{number of moles of solute}{volume in litres}

    putting the values in the equation, we get

molarity x volume = number of moles

0.200 X 0.5= number of  moles

number of moles = 0.1 moles

Atomic mass x number of moles = mass

putting the values in the above equation

164 x 0.1 = 16.4 grams

16.4 grams of sodium phosphate is present in 0.5 L of the solution to make a 0.2 M solution.
