How does a limiting reagent affect how much product is formed?
O A. The amount of product will be limited by the molar mass of the
limiting reagent
B. The amount of product will be limited by the sum of the reactant
coefficients.
C. The amount of product will be limited by the number of moles of
the limiting reagent.
D. The amount of product will be limited by leftover amounts of other
reactants.
Answer:
C. The amount of product will be limited by the number of moles of
the limiting reagent.
Explanation:
a p e x :)) i just took the quiz
The amount of product will be limited by the number of moles of
the limiting reagent. Hence, option C is correct.
What is a Limiting reagent?The reactant that gets consumed early in the reaction restricts the quantity of product which will be produced in the chemical reaction. Thus, the reactant that gets consumed early in a chemical reaction is a limiting reagent.
Hence, the amount of product will be limited by the number of moles of the limiting reagent.

How do most animals produce offspring
Answer:
Some animals produce offspring through asexual reproduction while other animals produce offspring through sexual reproduction. Both methods have advantages and disadvantages. Asexual reproduction produces offspring that are genetically identical to the parent because the offspring are all clones of the original parent.

A. unexpected change in odor
B. change in state of matter
C. formation of bubbles
D.precipitate was formed
Answer:
A. unexpected change in odor
Explanation: Common physical changes include melting, change of size, volume, color, density, and crystal form. Example the classic baking soda and vinegar reaction provides evidence of a chemical change due to the formation of a gas and a temperature change.
Explain why the pressure of a gas increases when its volume decreases.
HELP
Answer:
The gas pressure is raised by decreasing the volume of a gas. ... The particles can collide more often with the walls of the container because the volume has decreased. They exert force on them each time they collide with the walls. More collisions mean more force, so it will increase the strain.

1) How many moles of water does 6.02 x 1023 molecules
represent?
Answer:
1.00 mol
Explanation:
Step 1: Given data
Molecules of water: 6.02 × 10²³ molecules
Step 2: Calculate the number of moles corresponding to 6.02 × 10²³ molecules of water
In order to convert molecules to moles, we need a conversion factor. In this case, we will use Avogadro's number: there are 6.02 × 10²³ molecules in 1 mole of molecules.
6.02 × 10²³ molecules × 1 mol/6.02 × 10²³ molecules = 1.00 mol (we keep 3 significant figures)

A 18.5 gram sample of metal was added to a graduated cylinder that had
an initial volume of 45.50 mL. The water level raised to 54.10 mL. Using
this information, calculate the density of the metal. *
Answer:
[tex]d=2.15g/mL[/tex]
Explanation:
Hello there!
In this case, since the density of the metal is computed as shown below:
[tex]d=\frac{m}{V}[/tex]
We need to calculate the volume of the solid by subtracting the final volume and the initial volume of water:
[tex]V=54.10mL-45.50mL\\\\V=8.60mL[/tex]
Thus, we obtain:
[tex]d=\frac{18.5g}{8.60mL}\\\\d=2.15g/mL[/tex]

30. The density of an unknown gas at 27°C and 2 atm pressure is equal with density of N2 gas at
52°C and at 5 atm
pressure. Calculate the molar mass of that unknown gas.
pls help guys
Answer:
Molar mass of the unknown gas is 64.6 g/mol
Explanation:
Let's think this excersise with the Ideal Gases Law.
We start from the N₂. At STP conditions we know that 1 mol of anything occupies 22.4L.
We apply: P . V = n . R . T
5 atm . V = 1 mol . 0.082 . 325K
V = (1 mol . 0.082 . 325K) / 5 atm = 5.33 L
It is reasonable to say that, if we have more pressure, we may have less volume.
As this is the volume for 1 mol of N₂, our mass is 28 g. Then, the density of the nitrogen and the unknown gas is 28 g/5.33L = 5.25 g/L
Our unknown gas has, this density at 27°C and 2 atm.
If we star from this, again: 1 mol of any gas occupy 22.4L at STP, we can calculate the volume for 1 mol at those conditions:
P₁ . V₁ / T₁ = P₂ . V₂ / T₂
1 atm . 22,4L / 273K = 2 atm . V₂ / 300K
Remember that the value for T° is Absolute (T°C + 273)
[ (1 atm . 22.4L / 273K) . 300K] / 2 atm = V₂ → 12.3L
This is the volume for 1 mol of the unknown gas at 2 atm and 27°C
We use density to determine the mass: 12.3 L . 5.25 g/L = 64.6 g
That's the molar mass: 64.6 g/mol

What is the concentration of sodium ions in 0.185 M Na2CO3?
Answer:
0.370 M
Explanation:
Step 1: Given data
Molar concentration of the sodium carbonate solution: 0.185 M
Step 2: Write the balanced dissociation equation
Sodium carbonate is a strong electrolyte that dissociates according to the following equation.
Na₂CO₃(aq) ⇒ 2 Na⁺(aq) + CO₃²⁻(aq)
Step 3: Calculate the molar concentration of sodium ions
The molar ratio of Na₂CO₃ to Na⁺ is 1:2.
0.185 mol Na₂CO₃/L × 2 mol Na⁺/1 mol Na₂CO₃ = 0.370 mol Na⁺/L

A compound has a molar absorptivity of 40.9 cm ^ - 1 * M ^ - 1 at 293 nm. If a 1.00 cm cuvette is used, and the absorbance found to be 0.111, what is the concentration of the sample ?
Answer:
0.00271 M
Explanation:
To solve this problem we can use the formula:
A = ε * C * lWhere A is the absorbance, ε is the molar absorptivity, C is the molar concentration and l is the optical path length.
We input the data given by the problem:
0.111 = 40.9 cm⁻¹M⁻¹ * C * 1.00 cmAnd solve for C:
C = 0.00271 MThe study of chemicals is called chemistry.
The correct answer is 0.00271 M
To solve this problem the formula is used as follows:-
A = ε * C * l
The data is given as follows:-
A is the absorbance,ε is the molar absorptivity, C is the molar concentration l is the optical path length.
[tex]0.111 = 40.9 * C * 1.00[/tex]
After solving the equation the value of C is as follows:-
[tex]C = 0.00271 M[/tex]
Hence, the correct answer is 0.00271.
