Answer:

<u>only sodium chloride compounds</u> MOST LIKELY products of the reaction between sodium metal and chlorine gas.

Correct answer - C

Explanation:

A solid sodium metal reacts with gaseous form of chlorine gas to form  a solid sodium chloride.

This formation of sodium chloride arises due to transfer of one valence electron from sodium to chlorine atom and the both atoms get stable octet electronic configuration.

As a result, an ionic compound solid sodium chloride is formed.

The chemical reaction of formation sodium chloride is as follows.

2Na(s)+Cl_{2}(g) \rightarrow 2NaCl(s)

Therefore, <u>only sodium chloride compounds</u> MOST LIKELY products of the reaction between sodium metal and chlorine gas.

Identify the limiting reactant when 7.81 g of HCl reacts with 5.24 g of NaOH to produce NaCl and H2O
elena55 [62]

Answer:

NaOH is limiting

Explanation:

                                 Hcl   +    NaOH   ------------      Nacl   + H2O  

Given                     7.81g        5.24g

mol weights           1+35.5     23+16+1

                                 36.5            40

No of Moles        7.81/36.5       5.24/40  

                             0.2139              0.131

No of moles = weight/ molecular weight

No of moles of NaOH is  lower so it is limiting as according to equation one mole of Hcl requires mole of NaOH so equal number of moles are required. NaOH is 0.131 which is far lower than 0.2139

A sample of gas occupies 7.80 liters at 425°C? What will be the volume of the gas at 35°C if the pressure does not change?
Ksenya-84 [330]
V₁/T₁=V₂/T₂

T₁=425+273.15=698.15 K
T₂=35+273.15=308.15 K

V₂=V₁T₂/T₁

V₂=7.80*308.15/698.15=3.44 L

3.44 liters

Describe how a mole ratio is correctly expressed when it is used to solve a stoichiometry problem
notka56 [123]
Basically stoichiometry is the measurement of elements, that is, the study of chemical quantities consumed or produced in a chemical reaction. When we are performing it we are using a special chemical counting unit: the mole, a unit of measurement, and one mole of a substance contains 6.022 * 10^23 particles. Now mole ratio is defined as the ratio of moles of one substance to the moles of another substance in a balanced equation. <span>If we are looking for the mole ratio between two substances, we need to look at the balanced equations</span> for the coefficients in front of the substances you are interested in.
This should be your guiding mantra for doing stoichiometry problems!
