What is the total number of moles of O2(g) that must react completely with 5.00 moles of C4H10(g)?
Answers
Answer:
32.5 moles of O2(g) are necessaries for a complete reaction
Explanation:
Based on the reaction of combustion of C4H10(g):
C4H10(g) + 13/2 O2(g) → 4CO2(g) + 5H2O(g)
1 mole of C4H10 needs 13/2 moles O2 for a complete reaction.
That means, the moles of O2 required for a reaction of 5.00 moles of C4H10 are:
5.00 moles C4H10 * (13/2mol O2 / 1mol C4H10) =
32.5 moles of O2(g) are necessaries for a complete reaction

_HCN+_CUSO4=_CUSO4+_CU(CN)2
Answers
[0]HCN + CuSO4 = CuSO4 + [0]Cu(CN)2
Thus is because the left-hand side contain Hydrogen, whereas the right-hand side does not. To balance an equation, an element cannot be added. And therefore, Hydrogen must be removed completely, along with Carbon and Nitrogen, as they each formed a chemical bond with hydrogen, and the composition would change if so.
Explanation chemically :
HCN + CuSO4 = CuSO4 + Cu(CN)2
Left-hand side :
1 H
1 C
1 N
1 Cu
1 S
4 O
Right-hand side :
0 H
1 Cu
1 S
4 O
1 Cu
2 C
2 N
Comparison between the two sides :
First:
1 H = 0 H (therefore to balance it, times the left hand side by 0 : (0)(1) H = 0 H = 0 H)
Because we're multiplying the left-hand side hydrogen atom by 0, and it is bonded with Carbon and Nitrogen, Carbon and Nitrogen is multiplied by 0 as well.
(0) H x (0) C x (0) N = (0) HCN = 0
Hydrogen is balanced.
Second :
Left-hand side Carbon and Nitrogen is 0 (0HCN).
Therefore, right-hand side Carbon and Nitrogen must also be 0.
Cu(CN)2
0 should be multiplied to the CN bracket to bring them to 0. However, there is a Cu atom in from of the CN molecule. So the 0 would be placed in front of the Cu atom, like this :
(0) Cu(CN)2.
The 0 in front of the Cu atom ensures that all the atoms will be multiplied by 0
(0 Cu(CN)2 = (0) Cu x (0) (CN)2 = 0
Carbon and Nitrogen are balanced.
Third :
CuSO4 is already balanced as both sides have an equal amount of each atom.
Therefore, the answer is [0] HCN + [1] CuSO4 = [1] CuSO4 + [0] Cu(CN)2

A compound is a pure substance that is composed of elements chemically bonded in definite proportions. A compound can be broken down into simpler substances only by chemical reactions, such as electrolysis.
A solution is a homogeneous mixture, meaning that it is the same throughout. A solution is composed of one or more solutes dissolved in a solvent. The proportions of the solute(s) can vary, as the components of a solution are not chemically bonded.

Under the right conditions aluminum will react with chlorine to produce aluminum chloride.
2 Al + 3Cl2 -> 2 AlCl3
How many grams of aluminum chloride can be produced when 157.0g of aluminum react with excess chlorine?
Answer:775.9 g AlCl3
but what the steps pls help
Answers
Answer:
775.9 g
Explanation:
Step 1: Write the balanced equation
2 Al + 3 Cl₂ ⇒ 2 AlCl₃
Step 2: Calculate the mass corresponding to 157.0 g of Al
The molar mass of Al is 26.98 g/mol.
157.0 g × 1 mol/26.98 g = 5.819 mol
Step 3: Calculate the moles of AlCl₃ produced from 5.819 moles of Al
The molar ratio of Al to AlCl₃ is 2:2. The moles of AlCl₃ produced are 2/2 × 5.819 mol = 5.819 mol.
Step 4: Calculate the mass corresponding to 5.819 moles of AlCl₃
The molar mass of AlCl₃ is 133.34 g/mol.
5.819 mol × 133.34 g = 775.9 g

What is the best reason for carbon dioxide existing as a gas at standard temperature and pressure?
A)
Carbon dioxide molecules have the same spin within each of their orbitals.
As a result, the carbon dioxide molecules are less attracted to each other
when compared to the intramolecular bonds.
B)
Coulomb's law shows that the interaction between protons and electrons
within the atoms of each carbon dioxide molecule is significantly stronger
than the proton-electron interaction between each molecule.
C)
The entropy of carbon dioxide is much greater than the entropy of its
surroundings.
D)
Carbon dioxide has too much internal energy that the molecule-molecule
interaction cannot keep the molecules together.

Answers
Answer:
0.5
Explanation:
What is Keq for the reaction N2 + 3H2 = 2NH3 if the equilibrium concentrations are [NH3] = 2 M, [N2] = 1 M, and [H2] = 2 M?
Step 1: Given data
Equilibrium concentrations:
[N₂] = 1 M
[H₂] = 2 M
[NH₃] = 2 M
Step 2: Write the balanced equation
N₂(g) + 3 H₂(g) ⇄ 2 NH₃(g)
Step 3: Calculate the concentration equilibrium constant (Keq)
The concentration equilibrium constant is equal to the product of the concentrations of the products raised to their stoichiometric coefficients divided by the product of the concentrations of the reactants raised to their stoichiometric coefficients.
Keq = [NH₃]² / [N₂] × [H₂]³
Keq = 2² / 1 × 2³ = 0.5

A sample of a diatonic gas is loaded into an evacuated bottle at STP. The 0.25 L bottle contains 1.76 grams of the unidentified gas. Calculate the molar mass of the gas. What is the identity of the diatomic gas?
Answers
Answer:
(a) 157.7 g
(b) 7.04 g/dm³
Explanation:
(a) From the question,
According to Avogadro's Law,
1 mole of every gas at STP occupies a volume of 22.4 dm³
But mass of 1 mole of the diatomic gas = molar mass of the gas.
This Implies that,
The molar mass of the gas at STP occupies a volume of 22.4 dm³
From the question,
If,
0.25 L bottle contain 1.76 g of the gas,
Therefore,
Molar mass of the gas = (1.76×22.4)/0.25
Molar mass of the gas = 157.7 g.
(b) Density of the gas = mass/volume
D = m/v
Given: m = 1.76 g, v = 0.25 L = 0.25 dm³
Therefore,
D = 1.76/0,25
D = 7.04 g/dm³

Calculate the molarity of the two solutions.
The first solution contains 0.200 mol of NaOH in 2.00 L of solution.
The second is 15.5G of NaCl in 671mL of solution
Answers
Answer:
a) 0.100 M
b) 0.395 M
Explanation:
a) Calculate the molarity of a solution that contains 0.200 moles of NaOH (solute) in 2.00 L of solution
We will use the following expression for molarity.
[NaOH] = moles of solute / liters of solution
[NaOH] = 0.200 mol/2.00 L = 0.100 M
b) Calculate the molarity for a solution that contains 15.5 g of NaCl (solute, 58.44 g/mol) in 671 mL of solution
We will use the following expression for molarity.
[NaCl] = mass of solute / molar mass of solute × liters of solution
[NaCl] = 15.5 g / 58.44 g/mol × 0.671 L = 0.395 M

What is the limiting reactant in the following equation? How much Fe2O3 will be produced if 2.1 g of Fe reacts with 2.1 g of O2?
4 Fe + 3O2 —> 2Fe2O3
Answers
Answer:
Fe is limiting reactant and 3.00g of Fe2O3 will be produced
Explanation:
To solve this question we must convert the mass of each reactant to moles and, using the reaction we can find limiting reactant. With moles of limiting reactant we can find moles of Fe2O3 and its mass as follows:
Moles Fe -Molar mass: 55.845g/mol-
2.1g * (1mol / 55.845g) = 0.0376 moles
Moles O2 -Molar mass: 32g/mol-
2.1g * (1mol / 32g) = 0.0656 moles
For a complete reaction of 0.0656 moles of O2 are needed:
0.0656moles O2 * (4mol Fe / 3 mol O2) = 0.0875 moles Fe
As there are just 0.0376 moles,
Fe is limiting reactant
The mass of Fe2O3 is:
Moles:
0.0376 moles Fe* (2mol Fe2O3 / 4mol Fe) = 0.0188 moles Fe2O3
Mass:
0.0188 moles Fe2O3 * (159.69g / mol) =
3.00g of Fe2O3 will be produced
