Answer:

D. All of these.

Explanation:

For an equation to be balanced the number of atoms of each kind in the reactants and the products should be the same.

Then from this equation, CO  is a product.

Last, two carbon atoms undergo reaction with the oxygen molecule for complete reaction to occur. Each atom combines with one oxygen atom.

<u>Answer:</u>

<em>D) All of these</em>

<em></em>

<u>Explanation:</u>

2 C(s) + O_2 (g) > 2 CO(g)

Reactant side (Left side)  Element     Product side (Right side)

2                                                   C                                      2

2                                                   O                                      2

Balanced!!!

Balancing is making the number of atoms of each element same on both the sides  (reactant and product side).

To find the number of atoms of each element we multiply coefficient × subscript  

For example 5 Ca_1 Cl_2 contains  

5 × 1 = 5 ,Ca atoms and

5 × 2 = 10, Cl atoms  

If there is a bracket in the chemical formula

For example 3Ca_3 (P_1 O_4 )_2 we multiply coefficient × subscript × number outside the bracket.......... to find the number of atoms  (Please note: 3 is the coefficient, and if there is no number given then 1 will be the coefficient )

So

3 × 3 = 9 , Ca atoms  

3 × 1 × 2 = 6, P atoms  

3 × 4 × 2 = 24, O atoms are present.

C10H22 &gt; C8H18+C2H4 if only ethane can be sold what is the atom econmy of this process
insens350 [35]

Answer:

The atom economy of ethane in this process is 19.72 %.

What is atom economy?

The conversion efficiency of a chemical reaction in terms of all the atoms involved and the desired products produced is known as atom economy (atom efficiency/percentage).

Explanation:

C₁₀H₂₂ → C₈H₁₈ + C₂H₄

Molecular weight of C₁₀H₂₂ = 142.28

Molecular weight of C₈H₁₈ = 114.228
Molecular weight of C₂H₄ = 28.053

% Atom economy =     \frac {Molecular weight of C2H4} {Molecular weight of C10H22}

                             = \frac{28.053}{142.28}*100

                             = 19.716 %

                             ≈ 19.72 %

Estimate the molar mass of a gas that effuses at 1.6 times the effusion rate of CO2
Vlada [557]
To estimate the molar mass of the gas, we use Graham's law of effusion. This relates the rates of effusion of gases with their molar mass. We calculate as follows:

r1/r2 = √(m2/m1)    

where r1 would be the effusion rate of the gas and r2 is for CO2, M1 is the molar mass of the gas and M2 would be the molar mass of CO2 (44.01 g/mol) 

r1 = 1.6r2

1.6 = √(44.01 / m1)
m1 = 17.19 g/mol

When calcium metal is placed in water, hydrogen gas bubbles out, leaving a highly alkaline (basic) solution. Write the balanced
Blababa [14]

Answer:

Ca (s) + 2H₂O (l) →  Ca(OH)₂ (aq)  +  H₂ (g)

Explanation:

When solid calcium reacts with water, it produces the correspondent hydroxid and hydrogen gas.

The hydroxid which is produced, is the calcium hydroxid which is a strong base, that's why you talk about a highly alkaline solution.

Ca (s) + 2H₂O (l) →  Ca(OH)₂ (aq)  +  H₂ (g)

Calcium hydroxide is a strong base, that dissociates in water, as this:

Ca(OH)₂  →  Ca²⁺ (aq)  + 2OH⁻ (aq)

It's a basic solution,  is providing hydroxyl ions to the medium
