Explanation:
1. The number of eggs it takes to make 1 cake = 3 eggs
The number of eggs it takes to make 3 × 1 = 3 cake = 3 × 3 = 9 eggs
Therefore, the correct option is;
A. 9 eggs
2. The given reaction is presented as follows;
C₃H₈(g) + 5O₂(g) → 3CO₂(g) + 4H₂O(l)
In the above reaction, we have;
Moles of , O₂, reacted = 5 moles
Moles of , CO₂, produced = 3 moles
The ratio of the of O₂ reacted to moles of CO₂ produced = 5 moles:3 moles
∴ The ratio of the of O₂ reacted to moles of CO₂ produced = 5:3
The correct option is;
B. 5:3
3. The reaction is presented as follows;
O₂ (g) + C(s) → CO₂ (g)
From the reaction, 1 mole (12 g) of carbon produces 1 mole of CO₂
The molar mass of CO₂ = The mass of 1 mole of CO₂ = 44.01 g/mol
Given that the reaction is completed, the mass of CO₂ produced = The mass of 1 mole of CO₂ ≈ 44 g
The correct option is;
C. Exactly 44 g
4. The given reaction is presented as follows;
N₂ + 3 F₂ → 2NF₃
The initial number of atom = 2 + 6 = 8
The final number of atom = 2 × 4 = 8
∴ The initial number of atom = The final number of atom
Therefore, the number of atoms is conserved;
The mass of the reactants ≈ 28 g/mol + 3 × 37.996806 g/mol ≈ 141.993612 g/mol ≈ 142 g/mol
The mass of the product ≈ 2 × 71 g.mol = 142 g/mol
∴ The mass is conserved
Moles of reactants = 1 + 3 = 4
Moles of products = 2
∴ The number of moles is not conserved
The correct option is
C. Mass and atoms only
5. The molar mass of P₄ = 123.895048 g/mol
One mole of P₄ (123.895048 g) produces four moles (4 × 34.00) of PH₃
6.20 g of P₄. will produce (4 × 34.00)/(123.895048) × 6.20 g ≈ 6.80576 g ≈ 6.81 g
The correct option is D. 6.81 g of PH₃
6. The percentage yield = ((The actual yield)/(The ideal yield)) × 100
The actual yield of silver = 38.1 g
The ideal yield of silver = 43.1 g
∴ The percentage yield = ((38.1 g)/(43.1 g)) × 100 = 88.3990719258% ≈ 88.4%
The percentage yield = 88.4%
The correct option is C. 88.4%
7. The given chemical equation is presented as follows;
CS₂ (g) + 3 O₂ (g) → CO₂ (g) + 2 SO₂ (g)
The number of moles in 192 g of O₂ = 192 g/(32 g/mol) = 6 moles
Given that 3 moles of O₂ reacts with 1 mole of CS₂ to produce 1 mole of CO₂ and 2 moles SO₂, therefore 2 × 3 = 6 moles of O₂ will reacts with 2 × 1 = 2 moles of CS₂ to produce 2 moles of CO₂ and 4 moles SO₂
∴ The limiting reactant is;
B. O₂
8. The given chemical equation is presented as follows;
2 C₈H₁₈ (g) + 25 O₂ (g) → 16 CO₂ (g) + 18 H₂O (l)
The number of moles in 10 g of C₈H₁₈, n₁ = (10 g)/(114.26 g/mol)
The number of moles of CO₂ produced, n₂ = (10 g)/(114.26 g/mol) × 16/2 ≈ 0.7 moles
The mass of CO₂ produced, m ≈ 44.01 × n₂ ≈ 44.01 g/mol × 0.7 moles ≈ 30.807 grams ≈ 30.8 grams
The theoretical yield of CO₂ from completely burning 10.0 g of C₈H₁₈ ≈ 30.8 grams of CO₂
The correct option is D. 30.8 g CO₂
9. The correct option is B. The limiting reactants determine the maximum amount of product that can be formed
10. Option B, which has 3 atoms of each element combining to form a product with 1 atom of one element and 2 atoms of the other element
The correct option is B.
11. By the conservation of mass, we have;
The mass of the reactants = The mass of the products
Let 'x' represent the mass of zinc in the products of the reaction
Therefore, we have;
61 g of calcium + 207 g of zinc chloride = 169 g of calcium chloride + x g of Zinc
∴ x g = 61 g + 207 g - 169 g = 99 g
The mass of zinc in the products of the reaction, x g = 99 g
The correct option is;
C. 99 g
12. The quantity that must be used to convert from one chemical substance to another is the mole ratio
The correct option is D. mole ratio
13. The maximum mass of the product that could form in a reaction is called the theoretical yield, which is option C.

3 × 1 = 3.0 moles of O₂ will produce 3 × 2 = 6 moles of H₂O
The correct option is
A. 6.0 mol H₂O
15. 2 mole × 2.02 g/mol = 4.04 g of H₂ (g) produces 32.05 g CH₃OH (l)
∴ 5 g of H₂ (g) will produce 32.05 g × 5/4.04 ≈ 39.6658416 g ≈ 39.7 g of CH₃OH
The correct option is;
D. 39.7 g CH₃OH
16. 2 (2 × 216.59 g = 433.18 g) moles of HgO produces 1 mole of O₂
1.5 mole of O₂ will be produced by 1.5 × 2 = 3 moles (3 × 216.59 g = 649.77 g ≈ 650 g) of HgO
The correct option is A 650 g HgO
17. 3 moles of H₂ produces 2 moles of NH₃
The number of moles of NH₃ in 100 g of NH₃, n = 100 g/(17.04 g/mol) = 5.868544 moles
The number of moles of H₂ that will produce 5.868544 moles of NH₃ = 3/2 × 5.868544 moles = 8.802816 moles ≈ 8.8 moles
Therefore, the correct option is;
D. 8.8 mol H₂
18. The theoretical yield of PbO = (223.2/331.2) × 9.90 g = 6.67173913 g
The percentage yield = (5.51 g)/(6.67173913 g) × 100 ≈ 82.6%
The correct option is option B 82.6%.

D
The distance between the water molecules is the same in the liquid and the vapor.
The distance between the water molecules is the same in the liquid and the vapor.
Answers
Answer: I think the answer is B or C, its kind of hard.
As the number of atoms in the water vapor is equal to the number of atoms in the liquid water. Therefore, the mass of the water remains the same.
What is evaporation?Evaporation is a process that usually happens on the surface of water or liquid and it involves the conversion of the liquid phase into the gaseous phase. This process involves a change in the state of matter of water or liquids.
When the water is completely evaporated into water vapor the density of the water vapor is less than the density of the liquid water as the vapors occupy a large volume in comparison to liquid water.
But the number of atoms in the water vapor is the same as the number of atoms in the liquid water. The mass of the water is due to the mass of the atoms.
Therefore, the mass of the water remains the same during the phase transition from liquid water to water vapors. Therefore, option (C) is correct.

Answer:
Molecules in the water move in a circular motion
Explanation:
Because of its circular motion it causes the waves to look like open circles which makes it easy for people to surf on
Water molecules move up and forward, down and back, in an overall circular motion in the wave. Therefore, option A is correct.
What is circular motion ?Circular motion is defined as the movement of an object while rotating in a circle. Circular motion can be uniform or asymmetric.
The angular rate of rotation and speed are constant in uniform circular motion, but the rate of rotation changes in non-uniform circular motion.
This means that circular motion can occur only if there is a "center seeking" force present; otherwise, things will travel in a straight line.
Within the wave, the water molecules move in a circular motion. Each water particle moves in a complete circle during a single wave period. The circle traced by a water particle on the ocean surface as a wave passes a given point has a diameter equal to the height of the wave.
Thus, option A is correct.

For the reaction between aqueous silver nitrate and aqueous sodium chloride, write each of the following. The products of the reaction are aqueous sodium nitrate and solid silver chloride.
Complete equation
Complete ionic equation
Net ionic equation
Answers
Answer:
A balanced ionic equation shows the reacting ions in a chemical reaction. These equations can be used to represent what happens in precipitation reactions or displacement reactions.
Precipitation reactions
In a typical precipitation reaction, two soluble reactants form an insoluble product and a soluble product.
For example, silver nitrate solution reacts with sodium chloride solution. Insoluble solid silver chloride and sodium nitrate solution form:
AgNO3(aq) + NaCl(aq) → AgCl(s) + NaNO3(aq)
The Na+ ions and NO3- ions remain separate in the sodium nitrate solution and do not form a precipitate. Ions that remain essentially unchanged during a reaction are called spectator ions.This means these can be ignored when writing the ionic equation. Only how the solid silver chloride forms is needed to be shown:
Ag+(aq) + Cl-(aq) → AgCl(s)
In a balanced ionic equation:
the number of positive and negative charges is the same
the numbers of atoms of each element on the left and right are the same
Displacement reactions
Displacement reactions take place when a reactive element displaces a less reactive element from one of its compounds.
A common type of displacement reaction takes place when a reactive metal reacts with the salt of a less reactive metal. For example, copper reacts with silver nitrate solution to produce silver and copper(II) nitrate solution:
2AgNO3(aq) + Cu(s) → 2Ag(s) + Cu(NO3)2(aq)
In this reaction, the NO3- ions remain in the solution and do not react - they are the spectator ions in this reaction. So, they can be removed from the ionic equation:
2Ag+(aq) + Cu(s) → 2Ag(s) + Cu2+(aq)
Question
Explain why this ionic equation is balanced:
Ba2+(aq) + SO42-(aq) → BaSO4(s)
Hide answer
There are the same numbers of atoms of each element on both sides of the equation. The total charge on both sides is also the same (zero).
Question
Balance this ionic equation, which represents the formation of a silver carbonate precipitate:
Ag+(aq) + CO32-(aq) → Ag2CO3(s)

Question
