how does a substances temperature change when the average kinetic energy of its particles increases and they decrease
alukav5142 [94]
Temperature is a measure of the energy of moving particles, so if the average kinetic energy is increasing, then the temperature would increase as well.

A compound composed of only sulfur and aluminum is analyzed. The mass ratio of aluminum to sulfur is found to be 1.00:1.78.
marta [7]

Answer:

a. Al2S3.

Explanation:

Molar mass of Al =  26.98

Molar mass of S = 32.06.

Ratio of AL:S is 1 : 1.78

Dividing by the moles we get:

0.0371  : 0.0555

= 1 : 1.5

So its Al2S3.

fredd [130]

Answer:

2.5 mole of O2

Explanation:

From the equation we see that we need 5 molecules of oxygen to react with 2 molecules of C2H2.

This means that 5 moles of oxygen molecules are needed to completely react with 2 moles of C2H2, because a mole is a unit of particle count.

From that we can infer that to react with 1 mole of C2H2 we need half of 5 moles of oxygen - so 2.5 mole of oxygen molecules.

In the following experiment, a coffee-cup calorimeter containing 100 g of H2O is used. The initial temperature of the calorimete
AysviL [449]

Answer:

The final temperature of the solution in the calorimeter is 28,7°C

Explanation:

A -ΔH means that when you dissolve CaCl₂ you will produce heat. This heat you produce is:

3,3g CaCl₂×\frac{1 molCaCl_{2}}{110,98g}×82800J/mol = 2462,1 J

The specific heat capacity of solution is:

q = c×m×ΔT

Where q is energy: (2462,1J)

c is heat capacity of the solution (4,18J/g°C)

m is mass of solution (103,3g)

And ΔT is (T-23°C)

Solving for T:

T = 23C+\frac{2462,1J}{4,18J/gC*103,3g}

T = 28,7°C

I hope it helps!
