Answer:

\huge \boxed{\mathrm{CH_4+ 2O_2 \Rightarrow CO_2 +2 H_2O}}

\rule[225]{225}{2}

Explanation:

\sf CH_4+ O_2 \Rightarrow CO_2 + H_2O

Balancing the Hydrogen atoms on the right side,

\sf CH_4+ O_2 \Rightarrow CO_2 +2 H_2O

Balancing the Oxygen atoms on the left side,

\sf CH_4+ 2O_2 \Rightarrow CO_2 +2 H_2O

\rule[225]{225}{2}

CH4+O2  =  CO2+2H2O

C-1               C-1    

O-2              O-4

H-4               H-4

CH4+<u><em>2 </em></u>O2  =  CO2+2 H2O

C-1               C-1    

O-2-4           O-4

H-4               H-4

You add a 2 in front of the O2 on the reactant side so the Oxygen can balance on the Product side

To make a 2 M solution of calcium chloride (CaCl2), you would place how many grams of CaCl2 into a container and then add how mu
belka [17]

Answer:

For a volume of 1 liter, we have a total mass of 220 grams of CaCl2 ( Option A)

Explanation:

<u>Step 1: </u>Given data

The concentration of the solution we want to make is 2M

2M = 2 moles/ L So the volume = 1L

The molar mass of CaCl2 is = 40 + 2*35 = 110g/mole

<u>Step 2:</u> Calculate number of moles

If we consider the volume = 1 L then for a concentration of 2M, this means the number of moles is 2

<u>Step 3:</u>  Calculate mass

The molar mass of CaCl2 = 110 g/mole

This means 110 grams per 1 mole

for 2 moles the mass is 220 grams

This means that for a volume of 1 liter, we have a total mass of 220 grams of CaCl2
