Do all substances absorb heat the same way?
miv72 [106K]

Since particles are closer together, solids conduct heat better than liquids or gases. Conduction moves heat through a material. It keeps a fire going by spreading the heat through solid material. Radiation is a method of heat transfer that does not require particles to carry the heat energy.

Consider the chemical reaction in equilibrium.
Zarrin [17]
This is an application of Le Chatlier's principle:  What happens when we add a reagent to one side of an equation? The reaction will shift to the other side.  So heat is a reactant and we're adding more of it, the reaction must therefore, shift to the right ( or the products side).

If 3.89 × 1024 atoms of a noble gas is collected and it has a mass of of 848 grams, this element is most likely a. He b. Ne c. A
bearhunter [10]

Answer:

Xenon

Explanation:

Avogadro’s number represent the number of the constituent particles which are present in one mole of the substance. It is named after scientist Amedeo Avogadro and is denoted by N_0.

Avogadro constant:-

N_a=6.023\times 10^{23}

Let the molar mass of the element is x g/mol

So,

6.023\times 10^{23} atoms have a mass of x g

Also,

3.89\times 10^{24} atoms have a mass of \frac{x}{6.023\times 10^{23}}\times 3.89\times 10^{24} g

This mass is equal to 848 g

So,

\frac{x}{6.023\times 10^{23}}\times 3.89\times 10^{24}=848

x= 131.3 g/mol

This mass correspond to xenon.
