Balance the following equation: Fe2(SO4)3 + KOH --> K2SO4 + Fe(OH)3

Write the coefficients that you decide to balance the equation like this 3, 4, 3. If you do not add a coefficient in front of an element or compound, use a 1 in your answer. For instance the for this balanced equation: 2H2 + O2 --> 2H2O you would write your answer: 2, 1, 2

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.

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 :)

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 elements found in the human body would be the following:

1. hydrogen,

2. oxygen,

3. carbon

4. nitrogen

They are found throughout your body, mostly as water but also as components of biomolecules such as proteins, fats, DNA, and carbohydrates.

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.

"The five factors are: the latitude zone, the elevation of the land, topography (landforms), ocean currents and winds."

Explanation:

Answer:

The five factors that determine the weather of any land area are: the amount of solar energy received because of latitude; the area's elevation or proximity to mountains; nearness to large bodies of water and relative temperatures of land and water; the number of such storm systems as cyclones, hurricanes, and thunderstorms resulting from air-mass differences; and the distribution of air pressure over the land and nearest oceans, which produces varying wind and air mass patterns.

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.

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.

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)

Answer: 4.12

Explanation:

we know that the given mol is 8.23 mol and they are 2NaI and I2 so we will write the equation like this.

8.23mol NaI x 1mol of I2 ÷ 2molNaI = 4.115≅ 4.12 mol of I2

we placed NaI at the bottom to cancel out with the 8.23 mol of NaI
