In which reaction do four total molecules of reactants produce two total molecules of products?

Chemistry
1 answer:
Pachacha [2.7K]3 years ago
5 0

Answer:

option D = N₂ + 3H₂   →   2NH₃

Explanation:

The reaction in which the nitrogen and hydrogen are reacted to form the ammonia is true.

  N₂ + 3H₂   →   2NH₃

In this reaction we can see that one molecules of nitrogen react with three molecules of hydrogen and form two molecules of ammonia.

while the other options are in correct because,

2SO₂  +  O₂    →   2SO₃

In this reaction two molecules of SO₂ react with one molecule of oxygen and form two molecules of SO₃.

2H₂S  +  3O₂   →     2SO₂ + 2H₂O

In this reaction two molecules of H₂S react with three molecules of oxygen and produced four molecules of product.

SnO₂ +  2H₂   →  Sn + 2H₂O

This is also incorrect because three molecules of reactant form three molecules of product.

What is the overall charge of the compound frfr
matrenka [14]

Answer:

As any molecular or ionic compound, 0 net charge, as a hypothetical diatomic cation, 2+

Explanation:

The question states that this is a compound, and any molecular or ionic compound would have a net charge of 0.

However, such a compound doesn't exist. Francium generally exists in nature having a 1+ charge in its cation form. Combining two francium ions would result in a Fr_2^{2+} species which is simply a diatomic ion but not a compound.

In the reaction 2K + 2H2O→2KOH + H2 , which compound has an element ratio of 2:1 ?
Katyanochek1 [597]

Answer:

Option O = H₂O

Explanation:

Chemical reaction:

2K + 2H₂O   →     2KOH + H₂

In this balanced chemical equation we can see that water is the only compound that consist of two hydrogen atom and one oxygen atom. H : O

2 : 1 .

In case of KOH two hydroxyl and two potassium atom are present and ration is K:OH  1:1.

Find the number of molecules in .815 mole of O2​
Simora [160]

Answer:

4.9 × 10²³ molecules

Explanation:

Given data:

Number of molecules = ?

Number of moles of oxygen = 0.815 mol

Solution:

The given problem will solve by using Avogadro number.

It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.

The number 6.022 × 10²³ is called Avogadro number.

1 mole = 6.022 × 10²³ molecules

0.815 mol  ×  6.022 × 10²³ molecules  / 1 mol

4.9 × 10²³ molecules

How many moles of water are produced from the reaction of 50. 0g of methane.
Alja [10]

Answer:

Given the balanced equation

CH4 (g) + 2O2 (g) → CO2 (g) + 2H2O (g)

we know that we'll get one mole CO2 for every 1 mole CH4.  So let's calculate how many moles are in 50 g of CH4 by dividing it's mass by it's molar mass (16 g/mole).  I get 3.125 moles.  The equation says we should get the same number of moles of CO2, so set moles CO2 = 3.125 moles.  Then we can find the mass of CO2 by multipying by the molar mass of CO2 (44 g/mole).  We should expect 138 grams of CO2.
