You are given 24.3 grams of Mg and combine it with 32.1 grams of Sulfur, what is the mass of MgS? *
koban [17]

Answer:

ExplanatioFirst let us compute for the molar mass of Mg(OH)2.

molar mass = 24.3 + 2 (16) + 2(1.0)

molar mass = 58.3 g/mol

 

So the mass is then:

mass = 3.2 mol * (58.3 g/mol)

mass = 186.56 gramsn:

How many moles of C3H8 will be produced from 75 moles of CO2?C3H8 + 5 O2 → 3 CO2 + 4 H2O
levacccp [35]

25 moles of C3H8 will be produced from 75 moles of CO2.

<h3>Mole calculation</h3>

To find the value of moles of a product from the number of moles of a reactant, it is necessary to observe the stoichiometric ratio between them:

                             C_3H_8 + 5 O_2 = > 3 CO_2 + 4 H_2O

Analyzing the reaction, it is possible to see that the stoichiometric ratio is 1:3, so we can perform the following expression:

                           

                            C3H8                CO2

                                      \frac{1mol}{xmol} =\frac{3mol}{75mol}

                                         x = 25mol

So, 25 moles of C3H8 will be produced from 75 moles of CO2.

rewona [7]

Answer:

Gravity

Explanation:

All matter exerts a force, which is called , that pulls all other matter towards its center. The strength of the force depends on the mass of the object: the Sun has more gravity than Earth, which in turn has more gravity than an apple. Also, the force weakens with distance. Objects far from the Sun won’t be influenced by its gravity.

What amount of the excess reagent remains when 0.30 mol NH3 reacts with 0.40 mol O2 to produce NO and H2O? 4NH3 +502 + 4NO + 6H2
nirvana33 [79]

Answer: (D) 0.025 mol O_2

Explanation:

The given balanced equation is :

4NH_3+5O_2\rightarrow 4NO+6H_2O

According to stoichiometry :

4 moles of ammonia (NH_3) reacts with = 5 moles of oxygen (O_2)

Thus 0.30 moles of  ammonia  (NH_3)  reacts with = \frac{5}{4}\times 0.30=0.375 moles of oxygen (O_2)

Now as given moles of oxygen are more than the required amount, oxygen is the excess reagent.

moles of oxygen (O_2) left = 0.40 - 0.375 = 0.025

Thus 0.025 mol O_2 excess reagent remains.
