What maximum amount of ammonia in kilograms can be synthesized from 5.22 kg of h2 and 31.5 kg of n2?

Fiesta28 [93]

Consider the unbalanced reaction,

H₂ + N₂ ===> NH₃

Balance it to get

3 H₂ + N₂ ===> 2 NH₃

This tells you that for every 3 moles of H₂ and 1 mole of N₂ among the reactants, 2 moles of NH₃ are produced.

Look up the molar masses of each component element:

• H : 1.008 g/mol ===> H₂ : 2.016 g/mol

• N : 14.007 g/mol ===> N₂ : 28.014 g/mol

• NH₃ : 17.031 g/mol

Convert the given mass to moles for each reactant:

• H₂ :

(5.22 kg) × (1000 g/kg) × (1/2.016 mol/g) ≈ 2589.29 mol

• N₂ :

(31.5 kg) × (1000 g/kg) × (1/28.014 mol/g) ≈ 1124.44 mol

Now,

(2589.29 mol H₂) : (1124.44 mol N₂) ≈ (2.30 mol H₂) : (1 mol N₂)

so that the amount of N₂ consumed is

(2589.29 mol H₂) × (1 mol N₂) / (3 mol H₂) ≈ 863.095 mol N₂

leaving an excess of about 261.343 mol N₂, and producing

(2589.29 mol H₂) × (2 mol NH₃) / (3 mol H₂) ≈ 1726.19 mol NH₃

Convert this to a mass :

(1726.19 mol) × (17.031 g/mol) × (1/1000 kg/g) ≈ 29.3987 kg

So, up to 29.4 kg of NH₃ can be synthesized.

After reviewing the results of a math test, the teacher tells the class that those students who completed their review worksheet

Vsevolod [243]

The option that best describes how the teacher likely came to this conclusion is that:

The teacher conducted an observational study by comparing the performance on the test of those who completed their review worksheets to those who did not complete their review worksheets.

<h3>What is observational study?</h3>

An observational study is known to be a kind of study where a researcher do observes the subjects without having any form of interference with them.

Here, the researcher is said to have no control over any of the treatments that is used on the subjects. All the have to do is observe and record their findings.

See options below

A. The teacher conducted an observational study by comparing the performance on the test of those who completed their review worksheets to those who did not complete their review worksheets.

B. The teacher conducted a sample survey by asking students if they completed their review worksheets and if they think they did well on the test.

C. The teacher performed a controlled experiment in which one group of students decided not to complete their review worksheets and the other group decided to complete their review worksheets.

D. The teacher performed a random experiment in which the test scores of one group of students would be higher and the test scores of the other group would be lower.

NISA [10]

what is the formula of gravity ?

_________________________________________

<h3> GRAVITY</h3>

Newton's law of universal gravitation

$\qquad \qquad \qquad \qquad \: F = G \frac{m1 \: m2}{r²}$

F = FORCE

G=GRAVITATIONAL CONSTANT

M1 = MASS OF OBJECT 1

M2=MASS OF OBJECT 2

R = DISTANCE BETWEEN CENTERS OF THE MASSES
