How can changing the reaction conditions influence the yield of a chemical reaction?
please explain in detail

Answers

I’m not sure if this is what you’re looking for, but if the environmental conditions change, it can be impacted. If it’s humid, for example, the reaction can be subdued and you can have a lower percent yield. (In this situation, a chemical not being stored too well could cause it to react a bit with some water in the air before the experiment)

Answer:

I found this on the web hope this helps.  

Explanation:

Le Châtelier's Principle states that a change in pressure, temperature, or concentration will push the equilibrium to one side of the chemical equation. So, if you manipulate the conditions to favor the product side, you increase the yield and vice versa.

2. Hydrocarbons consist of carbon and hydrogen. 5.7 g of a hydrocarbon contains 4.8 g of carbon.
If the relative molecular mass of the hydrocarbon is 114, determine its molecular formula.​

Answers

Answer:

The molecular formula of the hydrocarbon compound is C₈H₁₈

Explanation:

The type of chemical substance in the question = Hydrocarbon

The mass of the hydrocarbon = 5.7 g

The mass of carbon in the given hydrocarbon (sample) = 4.8 g

The relative molecular mas of the hydrocarbon = 114 g

Therefore, the mass of hydrogen in the sample, H = 5.7 g - 4.8 g = 0.9 g

The ratio of the mass of carbon in the sample = 4.8/5.7

The ratio of the mass of hydrogen in the sample = 0.9/5.7

By the law of constant composition, we have;

The mass of carbon in a mole of the hydrocarbon = (4.8/5.7) × 114 g = 96 g

The molar mass of carbon, C = 12 g/mol

The number of moles of carbon in a mole of the hydrocarbon, 'n₁', is given as follows;

n₁ = 96 g/12 g = 8 moles

The mass of hydrogen in a mole of the hydrocarbon = (0.9/5.7) × 114 g = 18 g

The molar mass of hydrogen, H ≈ 1 g/mol

The number of moles of hydrogen in a mole of the hydrocarbon, 'n₂', is given as follows;

n₂ = 48 g/1 g = 18 moles

Therefore, in each each molecule of the compound, we have have 8 atoms of carbon, 'C', and 18 atoms of hydrogen, 'H'

Therefore, we get;

The molecular formula of the hydrocarbon compound is C₈H₁₈ which is the chemical formula for the hydrocarbon also known as octane

the following punnett square shows a cross between two hybrid flowers. if the flowers show incomplete dominance, what fraction are pure red? I NEED HELP PLZ!

Answers

Answer:

1/4

Explanation:

Incomplete dominance is when the dominant ("R") gene is not completely dominant and cannot fully mask or cover the recessive ("r") gene. This means that it will result in both genes expressing and a mix of traits appearing. In the case of a flower with "R" genes for red and "r" genes for white, the following possibly combinations exist:

RR = all red, no white "r" gene

Rr = pink, as both the "R" and "r" genes are expressed

rr = white, no red "R" gene

The Punnett Square shows that only one of the four phenotypes is RR and red.

I think it’s 1/4!!!!

A 1500 N force gives an object an acceleration of 3 m/s2.

What is the mass of the object?

Answers

Answer:

500kg.

Explanation:

Newton's Second Law relates force, mass and acceleration to one another through the equation:

F = ma

We can rearrange this equation algebraically to solve for mass:

m = F/a

Substituting our known values for the variables, we get:

m = 1500N/3m/s2

So mass of the object is 500kg.

We know it's kg because Newtons (N) are a unit defined as 1 kg/m/s2, so m/s2 cancels out when we divide :)

Nitrogen gas reacts with hydrogen gas to produce ammonia according to the following equation.

N2(g)+3H2(g) → 2NH3(g)
What is the mole of ammonia produced from 7.23 x 10−4 moles of the hydrogen reactant, assuming there is sufficient nitrogen to react?


7.23 x 10−47.23 x 10−4

8.42 x 10−38.42 x 10−3

4.82 x 10−44.82 x 10−4

4.83 x 10−3

Answers

Answer:

4.82 x 10^-4

Explanation:

7.23 x 10^-4 mol H2   l    2 mol NH3

------------------------------------------------------- =  

                                   l    3 mol H2

(7.23 x 10^-4) x 2   /  3 =

4.82 x 10^-4

Hope this helped! ;)

The mole of ammonia produced from 7.23 x 10⁻⁴ moles of the hydrogen reactant when there is sufficient nitrogen to react is 4.82×10⁻⁴.

What is moles?

Moles is a unit which is used to estimate the amount of any substance and it is represented as:
n = W/M , where

W = given mass

M = molar mass

Given chemical reaction is:
N₂(g) + 3H₂(g) → 2NH₃(g)

In the question it is given that sufficient moles of N₂ is present, so the formation of product depends on the moles of H₂. From the stoichiometry of the reaction, it is clear that:

3 moles of H₂ = produce 2 moles of NH₃

7.23×10⁻⁴ moles of H₂ = produce 2/3 × 7.23×10⁻⁴=4.82×10⁻⁴ moles of NH₃

Hence, option (C) is correct i.e. 4.82×10⁻⁴.

How many grams of Sulfur are there in 2.05 x 10^25 molecules of Calcium Sulfate?

Answers

Answer:

1090 grams Sulfur (3 sig-figs)

Explanation:

Given 2.05 x 10²⁵ molecules CaSO₄ => 2.05 x 10²⁵ Sulfur atoms (subscript = 1 mole).

Converting 2.05 x 10²⁵ sulfur atoms to moles, divide by Avogadro's Number

(= 6.023 x 10²³ sulfur atoms / mole sulfur) => 2.05 x 10²⁵ sulfur atoms/6.023 x 10²³ sulfur atoms/mole sulfur atoms = 34.036 moles sulfur atoms.

Converting 34.036 moles sulfur to grams sulfur multiply by formula wt. of sulfur (=32g/mole S)

=> 34.036moles S x 32g/mole S = 1089.158 grams S ≅ 1090 g S (3 sig-figs)
