How many grams of carbon is needed to react with hydrogen gas to produce 59.8 grams of acetylene (C2H2)?
Answers
Answer:
[tex]55.1657[/tex] grams/mol of carbon is needed to react with hydrogen gas to produce 59.8 grams of acetylene (C2H2)
Explanation:
The molecular weight of acetylene is 26.04 g/mol
Molecular weight of carbon is equal to 12.011 g/mol
Two carbon atom produces one acetylene molecule.
Thus, 2 * 12.011 g/mol of carbon is used to produce 26.04 g/mol of acetylene,
Amount of carbon required to produce 59.8 grams of acetylene
[tex]\frac{2*12.011}{26.04} * 59.8 \\= 55.1657[/tex]grams/mol

You start with 2.5g of magnesium and add it to 400mL of CO2 at 23 o C and 1atm. How many grams of magnesium oxide will be formed?
Answers
Answer:
0.664 g are formed by the reaction.
Explanation:
First of all, we determine the reaction:
Mg + CO₂ → MgO + CO
We need to determine the moles of the CO₂ by the Ideal Gases Law.
We convert to L, the volume → 400 mL = 0.4L
T° → 23°C + 273 = 296K
P . V = n . R .T
n = P . V / R .T
n = (1 atm . 0.4L) / (0.082 . 296K) → 0.0165 moles
Moles of Mg → 2.5 g . 1mol / 24.3g = 0.103 moles
As ratio is 1:1, CO₂ is the limiting reactant.
For 1 mol of Mg, we need 1 mol of gas
Then, for 0.103 moles of Mg, we need 0.103 moles of gas, but we only have 0.0165 moles.
If we see the product side, ratio is also 1:1
0.0165 moles of CO₂ must produce 0.0165 moles of MgO.
We convert the moles to mass → 0.0165 mol . 40.3 g /1mol = 0.664 g

262.5%
Answers
Answer:
[tex]\boxed {\boxed {\sf A. \ 38.1 \%}}[/tex]
Explanation:
Percent yield is the ratio of the amount actually produced to how much could theoretically be produced. It is found using this formula:
[tex]\% \ yield = \frac{actual \ yield}{theoretical \ yield} *100[/tex]
For this reaction, the theoretical or expected yield is 325.0 grams. The actual yield is 123.8 grams.
[tex]\% \ yield = \frac{ 123.8 \ g }{325.0 \ g }*100[/tex]
Divide.
[tex]\% \ yield = 0.380923077 *100[/tex]
[tex]\% \ yield = 38.0923077[/tex]
Round to the nearest hundredth. The 9 in the hundredth place tells us to round the 0 to a 1 .
[tex]\% \ yield \approx 38.1[/tex]
The percent yield is about 38.1%

A gas in a piston starts out with a volume of 156 mL, a temperature of 28.1° C, and a pressure of 1.12 atm. If it ends with a volume of 312 mL and a temperature of 87.2° C, what is the new pressure?
Answers
Answer:
0.67atm is the new pressure of the gas
Explanation:
To find one condition of a gas when pressure, volume and absolute temperature change we must use combined gas law:
[tex]\frac{P_1V_1}{T_1} =\frac{P_2V_2}{T_2}[/tex]
Where P is pressure, V is volume and T is absolute temperature of 1, initial state and 2, final state of the gas.
Replacing:
P₁ = 1.12atm
V₁ = 156mL
T₁ = 28.1°C + 273.15K = 301.25K
P₂ = ?
V₂ = 312mL
T₂ = 87.2°C + 273.15 = 360.35K
1.12atm*156mL / 301.25K = P₂*312mL / 360.35K
P₂ = 0.67atm is the new pressure of the gas

A) 9.96 grams of K2O
B) 14.5 grams of K2O
C) 28.9 grams of K2O
D) 57.8 grams of K2O
Answers
Answer:14.5 grams of K2O
Explanation:
4K(s) + O2(g) → 2 K2O(s). If a staff member at a laboratory has 12.0 grams of potassium metal, 14.5 grams of K2O is the theoretical yield of potassium oxide that the scientist could potentially produce from the reaction with oxygen gas. Therefore, option B is correct.
What is theoretical yield ?The yield of a reaction is used to represent how much of a product is produced from that reaction. The theoretical yield is the quantity of product that stoichiometry predicts will be produced, whereas the actual yield is the amount that is actually produced.
Divide the ratio by the limiting reactant's molecular weight. The answer is the theoretical yield of the desired product in moles.
It is useful to know how much product will be created with specific reactant amounts before carrying out chemical reactions. The theoretical yield is what is meant by this. This method can be applied to determine the theoretical yield of a chemical reaction.
Thus, option B is correct.

A sample of Oxygen gas is in a cylinder at constant temperature. What would happen to the pressure of the gas if the volume was
smooshed down to half its original size? Decreasing the volume by a factor of 2.
Answers
Answer:
This means that the pressure would become double of it's initial pressure.
Explanation:
Key statements:
- Constant temperature
- What happens to the pressure of the gas if the volume was
smooshed down to half its original size?
Basically the question is asking about the relationship between pressure and volume at constant temperature. This is given by Boyle's law.
Boyle's law states that the volume of a fixed mass of gas is inversely proportional to it's volume at a fixed temperature.
This is given by;
P1V1 = P2V2
Where;
P1 = Initial pressure
P2 = Final pressure
V1 = Initial Volume
V2 = Final Volume
From the question;
V2 = V1/2
Inserting it into the equation;
P1 V1 = P2 V1/2
Divide all through by V1
P1 = P2 /2
P2 = 2 P1
This means that the pressure would become double of it's initial pressure.

A 35g chunk of metal at 130C was dropped in a bucket containing 220g of water at 25C. The final temperature of the mixture
was 300. What is the specific heat capacity of the metal?
(Specific heat for water: 4184 J/g C) Formula (m)(c)(T) = (m) (c)(T)
Answers
Answer: The specific heat capacity of metal is [tex]1.31J/g^0C[/tex]
Explanation:
[tex]Q_{absorbed}=Q_{released}[/tex]
As we know that,
[tex]Q=m\times c\times \Delta T=m\times c\times (T_{final}-T_{initial})[/tex]
[tex]m_1\times c\times (T_{final}-T_1)=-[m_2\times c\times (T_{final}-T_2)][/tex]
where,
[tex]m_1[/tex] = mass of metal = 35 g
[tex]m_2[/tex] = mass of water = 220 g
[tex]T_{final}[/tex] = final temperature = [tex]30^0C[/tex]
[tex]T_1[/tex] = temperature of metal = [tex]130^oC[/tex]
[tex]T_2[/tex] = temperature of water = [tex]25^oC[/tex]
[tex]c_1[/tex] = specific heat of metal = ?
[tex]c_2[/tex] = specific heat of water = [tex]4.184J/g^0C[/tex]
Now put all the given values in equation (1), we get
[tex]m_1\times c_1\times (T_{final}-T_1)=-[m_2\times c_2\times (T_{final}-T_2)][/tex]
[tex]35\times c_1\times (30-130)^0C=-[220g\times 4.184\times (30-25)][/tex]
[tex]c_1=1.31J/g^0C[/tex]
Therefore, the specific heat capacity of metal is [tex]1.31J/g^0C[/tex]

The biggest error in this investigation is the use of inappropriate types of equipment.
The types of equipment used in the given setup are inappropriate. Suggested improvements in the apparatus to increase the accuracy are given below:
1. The use of a polystyrene cup in the laboratory for any reaction is inappropriate. As a slight increase in temperature causes the decomposition of the chemicals in the cup as well.
2. The use of a thermometer stand is a must. Without using the stand, the tip of the thermometer touches the lid of the container, which causes inaccuracies in the result.
