Why does the heat capacity decreases as atomic mass increases?

Answers

Answer 1

Answer: The general trend for a substance's heat capacity and atomic mass is that they are inversely proportional. This is because denser or larger atoms have particles that are closer to each other. The close proximity of these particles make it easier to transfer heat because of their increased vibration, making the heat capacity required smaller.

How many moles of atoms are in 5.00 g of 13C

Answers

0.384 moles of atoms are in 5.00 g of ¹³C of isotope.

How we calculate moles?

Moles of any substance will be calculate by dividing the given mass of the substance to the molar mass of that substance.

In the question given that:

Given mass of carbon = 5grams (because isotope of carbon is present ¹³C)

Molar mass of carbon = 13g/mol (because isotope of carbon is present ¹³C)

Moles of carbon = 5grams / 13g/mol

Moles = 0.384 moles

Hence, 0.384 moles is the required moles.

___wastes are solid, liquid, or gas wastes that are toxic, flammable, corrosive, reactive, or radioactive.a. solid
b. hazardous
c. domestic

Answers

Answer: Option (b) is the correct answer.

Explanation:

When a substance is used and thrown away which can lead to damage in the environment as it may [produce some toxic or hazardous gases is known as a hazardous waste.

These wastes can be solid, liquid or gaseous.

For example, batteries, kerosene, garden chemicals etc are all hazardous waste.

A domestic waste is a waste thrown by a household which may include paper, vegetable waste, cardboard, yard clippings etc.

Thus, we can conclude that hazardous wastes are solid, liquid, or gas wastes that are toxic, flammable, corrosive, reactive, or radioactive.

It's hazardous m8. :P

If 10.3 g of Mg3N2 is treated with water, what volume of gas would be collected at STP

Answers

Use the ideal gas law: PV=nRtTo find volume, move to V=(nRt)/PN=# of moles (to find, 10.3 g/100.929g)=.102 molesR=ideal gas constant(this value is 0.082056(Liters*atmospheres)/(Kelvin*mol)T= temp which at stp is 273 KelvinP= 1 atmosphereV=((.102 moles)(0.082056 Latm/Kmol)(273 K))/1 atm

Mg3N2 +6H2O → 3Mg(OH)2 +2 NH3
relative weight of Mg3N2 = (3x24)+(2x14) = 100 g/mole
mole of Mg3N2 = 10,3 g/100 g/mole = 0,103 mole
mole of NH3(g) = 2/1 x 0,103 mole = 0,206 mole
volume NH3(g) which collected at STP = mole NH3(g) x 22,4 litre/mole = 0,206 mole x 22,4 litre/mole = 4,6144 litre.
