Methane gas combusts according to the following
chemical equation:
CH4 (8) + 202(g) → CO2(g) + 2H2O(l)
29.2 L of methane gas is combusted with 63.3 L of
oxygen gas at STP. What volume of carbon dioxide
is produced in the reaction?
___L CO2
Your answer should be rounded to three significant figures. Do
not include units in your answer.
Answers
The volume of Carbon dioxide : 29.12 L
Further explanationGiven
ReactionCH4 (g) + 202(g) → CO2(g) + 2H2O(g)
Oxygen volume = 63.3 L
Methane volume = 29.2 L
RequiredThe volume of Carbon dioxide
Solution
1 mol gas at STP = 22.4 L
mol methane :
[tex]\tt \dfrac{29.2}{22.4}=1.3[/tex]
mol oxygen :
[tex]\tt \dfrac{63.3}{22.4}=2.83[/tex]
limiting reactant : CH₄(smaller ratio:mol/reaction coefficient)
So mol CO₂ based on CH₄
From equation, CO₂ : CH₄ = 1 : 1, so mol CO₂ = 1.3
The volume =
[tex]\tt 1.3\times 22.4=29.12~L[/tex]
The volume of carbon dioxide is produced in the reaction is 29.12 L
The calculation is as follows:We know that
1 mol gas at STP = 22.4 L
So,
The mol methane is
[tex]= 29.2 \div 22.4\\\\= 1.3[/tex]
Now
The mol oxygen is
[tex]= 63.3 \div 22.4\\\\= 2.83[/tex]
Now the volume is
[tex]= 22.4 \times 1.3[/tex]
= 29.12 L

Your mother gives you 250 mg of acetaminophen and a cup containing 500 ml of water. What is the concentration of the solution if you dissolve the Tylenol in the water?
Answers
Answer:
The concentration is 50%
Explanation:
Mass-Volume concentration is molarity (M) times 100% or [tex]\frac{Gsolute}{Lsoln}[/tex] * 100%
For this problem, we need to convert from milligrams to grams and milliliters to liters in order to plug the values into the equation and solve for the concentration.
So, 250 mg = 0.025g (there are 1000 mg in 1 g)
And 500ml = 0.05 L (there are 1000 ml in 1 L)
Now we can solve for the concentration
[tex]\frac{0.025 g}{0.05 L}[/tex] [tex]* 100[/tex] %= 0.5 [tex]* 100[/tex] % = 50% of Tylenol concentration

How much heat will a 45.00 g piece of glass require to change its temperature from 10 to 30 °C. The specific heat capacity is 0.500 J/g°C.
675 J
225 J
450 J
700 J
Answers
Answer:
Q = 450 J
Explanation:
Given that,
Mass of a piece of glass, m = 45 g
The temperature changes from 10°C to 30°C.
The specific heat is 0.5 J/g°C
We need to find heat required to raise the temperature. The formula that is used to find it is given by :
[tex]Q=mc\Delta T\\\\Q=45\times 0.5\times (30-10)\\\\Q=450\ J[/tex]
So, the required heat is 450 J. Hence, the correct option is (c).
