This is a combination reaction, where a hydrocarbon reacts in the presence of oxygen to produce carbon dioxide and water.
A) NaCl = 58.44 g/mol
number of moles : 2.14 / 58.44 = 0.0366 moles
V = n / M => 0.0366 / 0.270 = 0.1355 L
__________________________________________
b) C2H6<span>O = 46.06 g/mol
</span>number of moles : 4.30 / 46.06 = 0.0933 moles
<span>V = n / M => 0.0933 / 1.50 = 0.0622 L
</span>___________________________________________
c) CH3COOH = 60.0 g/mol
number of moles : 0.85 / 60.0= 0.0141 moles
V = n / M => <span> 0.0141 </span>/ 0.30 = 0.047 L

Answer:
The answer to your question is it is not at equilibrium, it will move to the products.
Explanation:
Data
Keq = 2400
Volume = 1 L
moles of NO = 0.024
moles of N₂ = 2
moles of O₂ = 2.6
Process
1.- Determine the concentration of reactants and products
[NO] = 0.024 / 1 = 0.024
[N₂] = 2/1 = 2
[O₂] = 2.6/ 1= 2.6
2.- Balanced chemical reaction
N₂ + O₂ ⇒ 2NO
3.- Write the equation for the equilibrium of this reaction
Keq = [NO]²/[N₂][O₂]
- Substitution
Keq = [0.024]² / [2][2.6]
-Simplification
Keq = 0.000576 / 5.2
-Result
Keq = 1.11 x 10⁻⁴
Conclusion
It is not at equilibrium, it will move to the products because the experimental Keq was lower than the Keq theoretical-
1.11 x 10⁻⁴ < 2400
Answer:
Mice
Explanation:
Small, rodent-like mammals, such as voles and mice, are the primary prey for many owl species. An owl's diet may also include frogs, lizards, snakes, fish, mice, rabbits, birds, squirrels, and other creatures. Occasionally, Great Horned Owls might even find skunks tasty enough to eat.

Answer:
The answer will result in one significant digit.
Explanation:
1. Subtract:
12.1 - 12.004 = 0.096
2. ROund to the correct number of significant digits:
For addition and subtraction we round the sum or the difference to the least number of digits after the decimal point there are in the problem.
For example, SInce 12.1 has one number after the decimal point and 12.004 has three numbers after the decimal point, we round the answer to one number after the decimal point because 12.1 is the number in the problem which has the least amount of digits after the decimal point.
We round 0.096 to 0.1.
0.1 has one significant digit.
