Answer:
2C₄H₁₀(g) + 13O₂(g) —> 8CO₂(g) + 10H₂O(g)
Explanation:
The balanced equation for the reaction between butane and oxygen to produce carbon dioxide and water can be written as follow:
C₄H₁₀ + O₂ —> CO₂ + H₂O
Next, we shall balanced the equation. This is illustrated below:
C₄H₁₀ + O₂ —> CO₂ + H₂O
There are 4 atoms of C on the left side and 1 atom on the right side. It can be balance by writing 4 before CO₂ as shown below:
C₄H₁₀ + O₂ —> 4CO₂ + H₂O
There are 10 atoms of H on the left side and 2 atoms on the right side. It can be balance by writing 5 before H₂O as shown below:
C₄H₁₀ + O₂ —> 4CO₂ + 5H₂O
There are 2 atoms of O on the left side and a total of 13 atoms on the right side. It can be balance by writing 13/2 before O₂ as shown below:
C₄H₁₀ + 13/2O₂ —> 4CO₂ + 5H₂O
Multiply through by 2 to express in whole number ratio.
2C₄H₁₀(g) + 13O₂(g) —> 8CO₂(g) + 10H₂O(g)
Thus, the equation is balanced.
(PLEASE HELP) 500 mL of a gas is collected at 745 mmHg. What will the volume be at 1.8 atm?
Answer:
272.22 mLExplanation:
The new volume can be found by using the formula for Boyle's law which is
[tex]P_1V_1 = P_2V_2[/tex]
where
P1 is the initial pressure
P2 is the final pressure
V1 is the initial volume
V2 is the final volume
Since we're finding the new volume we have
[tex]V_2 = \frac{P_1V_1}{P_2} \\[/tex]
First convert 745 mmHg to atm
760 mmHg = 1 atm
745 mmHg = 745/760 = 0.98 atm
We have
[tex]V_2 = \frac{500 \times 0.98}{1.8} \\ = 272.222...[/tex]
We have the final answer as
272.22 mLHope this helps you

Given the following equation: Na2O + H2O ---> 2 NaOH
How many moles of NaOH are produced from 1.02 moles of Na2O?
Answer:
2.04 moles
Explanation:
Since the ratio of Na2O to NaOH is 1:2, you multiply the number of moles by 2, equaling 2.04 moles.
Which refers to solid ice that condenses and forms on surfaces like grass or windows?
dew
frost
hail
sleet
Frost refers to solid ice that condenses and forms on surfaces like grass or windows.
WHAT IS FROST?Frost refers to a deposit of small white ice crystals formed on solid surfaces when the temperature falls below freezing temperature.
Frost forms when the temperature of the atmosphere is below freezing i.e. < 0°C.
Therefore, frost refers to solid ice that condenses and forms on surfaces like grass or windows.

What is the role of the producer in any food chain?
Question 1 options:
Producers turn light energy into food energy
Producers make the food that consumers eat
Without producers, consumers would starve
All of these answers are correct
Answer:
All of these answers are correct.
Explanation:
They are all correct because producers make their food(energy) through photosynthesis, they provide food to herbivores and therefore the rest of the food chain, and without them, the food chain would collapse and all the consumers would starve.

Answer:
B
Explanation:
A cylinder is filled with 10.0 L of gas and a piston is put into it. The initial pressure of the gas is measured to be 273. kPa.
The piston is now pulled up, expanding the gas, until the gas has a final volume of 50.0 L. Calculate the final pressure of the gas. Be sure your answer has the
correct number of significant digits.
P2 = 54.6 kPa
Explanation:
Given:
V1 = 10.0 L. V2 = 50.0 L
P1 = 273 kPa. P2 = ?
We can use Boyle's law to solve this problem.
P1V1 = P2V2
Solving for P2,
P2 = (V1/V2)P1
= (10.0 L/50.0 L)(273 kPa)
= 54.6 kPa
