How many grams of MgBr2 are needed to create 3.0L of a 4.5M aqueous solution of magnesium bromide?

Answers

Answer:

2486 g

Explanation:

First we calculate how many moles of MgBr₂ are required to create such a solution, using the definition of molarity and the given volume and concentration:

Molarity = moles / liters4.5 M = moles / 3.0 Lmoles = 4.5 M * 3.0 L = 13.5 mol

Now we convert 13.5 moles of MgBr₂ into grams, using its molar mass:

13.5 mol * 184.113 g/mol = 2486 g

If a gas is cooled from 315K to 231K and the volume is kept constant, what would the final pressure be if the original pressure was 621 mmHg ?

Answers

Answer:

455.4 mmHg

Explanation:

To solve this problem we can use Gay Lussac's Law, which describe the temperature and pressure of a gas, at constant volume and composition:

P₁T₂ =  P₂T₁

In this case:

P₁ = 621 mmHgP₂ = ?T₁ = 315 KT₂ = 231 K

We input the data:

621 mmHg * 231 K = P₂ * 315 K

And solve for P₂:

P₂ = 455.4 mmHg

Answers

A

Because Aluminum atoms tend to lose electrons in order to achieve an insert gas configuration. The aluminum atoms need to lose 3 electrons in order to attain the neon configuration , so it forms a trip of positive action

Answer:

Aluminium & Phosphorus (C & D)

Explanation:

Both these elements need to form positive ions with a +3 charge as they need to lose their 3 electrons to form a stable state in their configuration.

Show work please

Answers

Answer:

we find the mass for each element in one mole by multiplying the number of atoms in one molecule with the atomic mass

mC=8Ac=8*12=96g

mH=10AH=10*1=10g

mN=4AN=4*14=56g

mO=2AO=2*16=32g

by adding the masses together we find the molar mass of the molecule

M=mC+nH+mN+mO=96+10+56+32=194g/mole

we apply the rule of threes to find the percentage of each element

194g..96gC..10gH...56gN....32gO

100g....a...........b...........c.............d

a=(100*96)/194=49.48%C

b=(100*10)/194=5.19%H

c=(100*56)/194=28.85%N

d=(100*32)/194=16.48%O

A 7.0 L sample of gas begins at 2.5 atm and 320. K. What is the new pressure if the temperature is changed to 273 K and the volume remains constant at 7.0 L?

Answers

Answer:

2.1 atm

Explanation:

We are given the following variables to work with:

Initial pressure (P1): 2.5 atm

Initial temperature (T1): 320 K

Final temperature (T2): 273 K

Constant volume: 7.0 L

We are asked to find the final pressure (P2). Since volume is constant, we want to choose a gas law equation that relates initial pressure and temperature to final pressure and temperature. Gay-Lussac's law does this:

[tex]\frac{P_{1}}{T_1} =\frac{P_{2}}{T_2} \\[/tex]

We can rearrange the law algebraically to solve for [tex]P_{2}[/tex].

[tex]{P_{2}} =\frac{(T_2)(P_{1} )}{T_1} \\[/tex]

Substitute your known variables and solve:

[tex]P_2 = \frac{273K(2.5atm)}{320K} = 2.1 atm[/tex]

When 23.15 g of N, and 36.85 g of H2 react, what is the maximum amount of NH3 that can be produced?

Answers

Answer:

28.23 g NH₃

Explanation:

The balanced chemical equation is:

N₂(g) + 3 H₂(g) → 2 NH₃(g)

Thus, 1 mol of N₂ reacts with 2 moles of H₂ to produce 2 moles of NH₃. We convert the moles to mass (in grams) by using the molecular weight (MW) of each compound:

MW(N₂) = 2 x 14 g/mol = 28 g/mol

mass N₂= 1 mol x 28 g/mol = 28 g

MW(H₂) = 2 x 1 g/mol = 2 g/mol

mass H₂ = 3 mol x 2 g/mol = 6 g

MW(NH₃) = 14 g/mol + (3 x 1 g/mol) = 17 g/mol

mass NH₃= 2 moles x 17 g/mol = 34 g

Now, we have to figure out which is the limiting reactant. For this, we know that the stoichiometric ratio is 28 g N₂/6 g H₂. If we have 36.85 g of H₂, we need the following mass of N₂:

36.85 g H₂ x 28 g N₂/6 g H₂ = 171.97 g N₂

We have 23.15 g N₂ and we need 171.97 g. So, we have lesser N₂ than we need. Thus, the limiting reactant is N₂.

Now, we calculate the product (NH₃) by using the stoichiometric ratio 34 g NH₃/28 g N₂, with the mass of N₂ we have:

23.25 g N₂ x 34 g NH₃/28 g N₂ = 28.23 g NH₃

Therefore, the maximum amount of NH₃ that can be produced is 28.23 grams.
