Answer:
c ) 16
Explanation:
C4 H10 O + 6 O2 =====> 4 CO2 + 5 H2O
1 + 6 + 4 + 5 = 16
Answer:
C.) 16
Explanation:
An equation is balanced when there are equal amounts of each element on both sides of the reaction. These values can be modified by adding coefficients.
The unbalanced equation:
C₄H₁₀O + O₂ -----> CO₂ + H₂O
Reactants: 4 carbon, 10 hydrogen, 3 oxygen
Products: 1 carbon, 2 hydrogen, 3 oxygen
The balanced equation:
1 C₄H₁₀O + 6 O₂ -----> 4 CO₂ + 5 H₂O
Reactants: 4 carbon, 10 hydrogen, 13 oxygen
Products: 4 carbon, 10 hydrogen, 13 oxygen
Now, you can add the coefficients:
1 + 6 + 4 + 5 = 16

What is the percent yield when 68. 5 kg of carbon monoxide is reacted with 8. 60 kg of hydrogen gas to produce methanol (ch3oh)? the actual yield of methanol was 3. 57 x 104 g
Answers
Hence the percent yield of methanol is 51.45%
Step 1: Convert Kg into g
68.5 Kg CO = 68500 g CO
8.60 Kg H₂ = 8600 g
Step 2: Find out the Limiting reactant;
The Balance Chemical Equation is as follows;
CO + 2 H₂ → CH₃OH
According to Equation,
28 g (1 mol) CO reacts with = 4 g (2 mol) of H₂
So,
68500 g CO will react with = X g of H₂
Solving for X,
X = (68500 g × 4 g) ÷ 28 g
X = 9785 g of H₂
It shows that 9785 g H₂ is required to react with 68500 g of CO but we are provided with 8600 g of H₂ which is less than required. Therefore, H₂ is provided in less amount hence, it is a Limiting reagent and will control the yield of products.
Step 3: Calculate Theoretical Yield
According to the equation,
4 g (2 mol) H₂ reacts to produce = 32 g (1 mol) Methanol
So,
8600 g H₂ will produce = X g of CH₃OH
Solving for X,
X = (8600 g × 32 g) ÷ 4 g
X = 68800 g of CH₃OH
Step 4: Calculate %age Yield
%age Yield = Actual Yield ÷ Theoretical Yield × 100
Putting Values,
%age Yield = 3.54 × 10⁴ g ÷ 68800 g × 100 = 51.45 %

For the reaction c 2h₂ ---> ch₄, how many moles of hydrogen are required to produce 10 mol of methane, ch₄
Answers
The number of moles of hydrogen required will be 20 moles.
Stoichiometric mole ratioFirst, let us look at the balanced equation of the reaction:
[tex]C + 2H_2 --- > CH_4[/tex]
From the above equation, it is obvious that 1 mole of carbon requires 2 moles of hydrogen in order to produce a mole of methane.
In other words, the mole ratio of hydrogen to methane is 2:1. For every 1 mole of methane produced, 2 moles of hydrogen are consumed.
Now, what we want to produce is 10 moles of methane. The amount, in moles of hydrogen required, is calculated by:
10 moles x 2 = 20 moles.
Thus, 20 moles of hydrogen would be required to produce 10 moles of methane.

If 24. 7 g of barium chloride reacts with excess sodium sulfate, how many grams of sodium chloride will be produced
Answers
6.9 g of sodium chloride will be produced.
Antoine Lavoisier discovered in 1789 that mass is neither created nor destroyed in chemical reactions, which led to the formulation of the Law of Conservation of Mass. That is to say, the mass of any one element at the start of a reaction will be equal to that element's mass at the conclusion of the reaction.
The total mass of the reactants and products are equal under the principle of conservation of mass.
BaCl₂ + Na₂SO₄ => BaSO₄ + 2NaCl
Molecular weight of BaCl₂ = 137 + 35.5 × 2
= 208 g/mole
Molecular weight of NaCl = 22.99 + 35.45
= 58.44 g/mole
208 g/mol BaCl₂ produces 58.44 g/mole NaCl.
1 g/mol BaCl₂ produces (58.44 / 208) g/mole NaCl.
24.7 g BaCl₂ produces (58.44 / 208) × 24.7 g NaCl
= 6.9 g NaCl
Therefore, 6.9g of sodium chloride will be produced.

The bluish color that makes the atmosphere of neptune so beautiful to the human eye is caused by the interaction of sunlight with what gas?
Answers
The bluish color that makes the atmosphere of neptune so beautiful to the human eye is caused by the interaction of sunlight with methane gas.
The compositions of Uranus but also Neptune are fairly similar at high altitudes. The existence of methane in both ice giants' upper atmospheres may be responsible for their blue hue. The majority of the red light that strikes the planets is absorbed by methane, giving the planets their blue appearance.
The blue marble occurrence of the faraway planet is actually a result of methane gas clouds. Methane is a gas that, despite making up a very small fraction of Neptune's atmosphere, absorbing red light's wavelengths while reflecting blue light outward.

Answers
Answer:

Explanation:
Before you can calculate the molarity, you need to convert grams to moles (via molar mass) and convert mL to L.
(Step 1)
Molar Mass (C₈H₅O₄K):
8(12.011 g/mol) + 5(1.008 g/mol) + 4(15.998 g/mol) + 39.098 g/mol
Molar Mass (C₈H₅O₄K): 204.218 g/mol
0.6013 g C₈H₅O₄K 1 mole
------------------------------ x ------------------ = 0.00294 moles C₈H₅O₄K
204.218 g
(Step 2)
1,000 mL = 1 L
32.47 mL 1 L
--------------- x ----------------- = 0.03247 L
1,000 mL
(Step 3)
Molarity (M) = moles / volume (L)
Molarity = 0.00294 moles / 0.03247 L

Answers
the coefficient of performance of this heat pump is 8.61.
What is Heat pump ?
The air source heat pump converts heat from the ambient air into a low-temperature liquid refrigerant. The pump compresses the liquid to raise its temperature using power. To release the heat it had been holding, it then condenses back into a liquid. Your underfloor heating system or radiators get heat.
coefficient of performance -The usable heating or cooling delivered to work (energy) needed ratio, also known as the coefficient of performance, or COP, of a heat pump, refrigerator, or air conditioning system. Higher efficiency, less energy (power) usage, and thus reduced operational costs are all related to higher COPs.
temperature of cold reservoir = -14.0°C
Tc = [ 273+ (-14.0)]K = 259K
temperature of hot reservoir = 20°C
Th = [ 273+ (20)]K = 293K

A gaseous mixture containing 32.00 g n2 and 16.00 g ne is placed into an 4.00 l vessel at 0.00 °C. What is the pressure of the mixture?
Answers
The pressure of the mixture can be found out adding the Partial Pressure of the gas.
Partial pressure of gas is the pressure if it alone occupied the entire volume of original mixture.
Moles = given mass / molar mass
Given,
Mass of Nitrogen = 32g
Molar Mass of Nitrogen = 28g
Mass of Neon = 16g
Molar Mass of Neon = 20g
Volume of gas = 4L
Temperature of vessel = 0°C = 273K
Partial Pressure of nitrogen = P₁
Partial Pressure of neon = P₂
Moles of nitrogen, n₁= 32/28 = 1.14
Moles of neon, n₂= 16/20 = 0.8
Using Ideal gas equation for Nitrogen,
∴ P₁V = n₁RT
⇒ P₁ (1) = 1.14 × 0.082 × 273
⇒ P₁ = 25.52atm
Using Ideal gas equation for Neon,
∴ P₂V = n₂RT
⇒ P₂ (1) = 0.8 × 0.082 × 273
⇒ P₂ = 17.9 atm
Total pressure of the mixture can be found out by adding the partial pressures of both the gases.
Total pressure P = P₁ + P₂
P = 25.52 + 17.9 atm
P = 43.42 atm
Hence, total pressure of the mixture is 43.42atm
