Answer: Filtration

Explanation:

Chromatography : It is a type of separation process in which the liquid or gas is separated into components at different rate.

Filtration : It is a type of mechanical separation process in which the solid is separated from the liquid through the filter paper. The beans which are larger in size remain as such and the the coffee passes through the filter.

Fractional distillation is a process by which components in a chemical mixture are separated into different parts called as fractions according to their different boiling points.

Simple Distillation : It is a type of separation process in which the mixture of liquid separated or evaporated at different temperatures.

The table shows a chemical equation and the dimensional analysis used by a student to calculate the number of moles of Ba3N2 req

UNO [17]

This problem is providing the chemical reaction whereby barium nitride reacts with water to produce barium hydroxide and ammonia, so the number of moles of barium nitride are required in order to produce 8.3 moles of ammonia. It asks for us to evaluate the student's setup, so we conclude the answer is C. "1 mol of NH3 should be replaced with 2 mol of NH3", according to:

<h3>Mole ratios:</h3>

In chemistry, stoichiometric calculations are used to figure out the moles or mass of a substance, given information about another one in the reaction. In this case, for the given chemical equation:

$Ba_3N_2 + 6H_2O \rightarrow 3Ba(OH)_2 + 2NH_3$

We evidence a 1:2 mole ratio of barium nitride to ammonia, for that reason, the student's setup:

$8.3 mol NH_3 * \frac{1 mol Ba_3N_2 }{1 mol NH_3}$

Is incorrect, because the ammonia must be accompanied by a 2 rather than the 1 it is given there:

$8.3 mol NH_3 * \frac{1 mol Ba_3N_2 }{2mol NH_3}$

Thereby, the correct answer is C. "1 mol of NH3 should be replaced with 2 mol of NH3"

Solar system question

shtirl [24]

Answer:

yes

Explanation:

is that is the alteration of a planet on its orbit around the sun depends upon the mass of the Sun and the inverse square of the planets distance from the Sun. As a planet moves further away in its orbit around the Sun, the gravitational force exerted by the sun on the planet decreases

What is the final concentration if a 50.0 mL sample of a 15% H2SO4 solution is added to water to give a final volume of 250 mL?

Anna007 [38]

Answer:

The answer to your question is 3% H2SO4 solution

Explanation:

Data

Concentration 2 = C₂ = ?

Concentration 1 = C₁ = 15 %

Volume 1 = V₁ = 50 ml

Volume 2 = V₂ = 250 ml

Formula

C₁V₁ = C₂V₂

Solve for C₂

C₂ = C₁V₁ / V₂

Substitution

C₂ = (15)(50) / 250

Simplification and result

C₂ = 3 %

How the proton H gradient is used to make ATP

sladkih [1.3K]

Answer:

The proton gradient produced by proton pumping during the electron transport chain is used to synthesize ATP. Protons flow down their concentration gradient into the matrix through the membrane protein ATP synthase, causing it to spin (like a water wheel) and catalyze conversion of ADP to ATP.
