Explanation:

The chemical equation below shows the decomposition of ammonium nitrate (NH4NO3). NH4NO3 Right arrow. N2O 2H2O A chemist who is performing this reaction starts with 160. 1 g of NH4NO3. The molar mass of NH4NO3 is 80. 03 g/mol; the molar mass of water (H2O) is 18. 01 g/mol. What mass, in grams, of H2O is produced? 9. 01 18. 01 36. 03 72. 6.

Answers

The mass of water, H₂O produced from the reaction is 72.06 g

We'll begin by calculating the mass of NH₄NO₃ that reacted and the mass of H₂O produced from the balanced equation.

NH₄NO₃ —> N₂O + 2H₂O

Molar mass of NH₄NO₃ = 80.03 g/mol

Mass of NH₄NO₃ from the balanced equation = 1 × 80.03 = 80.03 g

Molar mass of H₂O = 18.01 g/mol

Mass of H₂O from the balanced equation = 2 × 18.01 = 36.02 g

From the balanced equation above,

80.03 g of NH₄NO₃ reacted to produce 36.02 g of H₂O

Finally, we shall determine the mass of H₂O produced by the reaction of 160.1 g of NH₄NO₃.

From the balanced equation above,

80.03 g of NH₄NO₃ reacted to produce 36.02 g of H₂O.

Therefore,

160.1 g of NH₄NO₃ will react to produce = (160.1 × 36.02) / 80.03 = 72.06 g of H₂O.

Thus, the mass of water, H₂O produced from the reaction is 72.06 g

O B. 1.00 mole of H2SO4
о
C. 1.00 mole of HBr

Answers

Hope this will help
I think it’s B

A 1.00 mole of Sulfuric acid (H₂SO₄) contains the largest number of atoms (7 atoms/molecule). Option B is correct.

To determine which of the given compounds contains the largest number of atoms in 1.00 mole, we need to consider the number of atoms in each compound.

1.00 mole of NH₃ contains:

1 mole of N atoms (1 atom/molecule)

3 moles of H atoms (3 atoms/molecule)

Total atoms = 1 + 3 = 4 atoms/molecule

1.00 mole of H₂SO₄ contains:

2 moles of H atoms (2 atoms/molecule)

1 mole of S atoms (1 atom/molecule)

4 moles of O atoms (4 atoms/molecule)

Total atoms = 2 + 1 + 4 = 7 atoms/molecule

1.00 mole of HBr contains:

1 mole of H atoms (1 atom/molecule)

1 mole of Br atoms (1 atom/molecule)

Total atoms = 1 + 1 = 2 atoms/molecule

Therefore, 1.00 mole of H₂SO₄, contains the largest number of atoms.

Hence, B. is the correct option.

How many grams of barium chloride are produced when 1.25 x 1023 molecules of HCl reacts with barium?

Answers

Considering the reaction stoichiometry and Avogadro's Number, the mass of barium chloride produced is 21.6 grams.

Balanced reaction

The balanced reaction is

2 HCl + Ba → BaCl₂ + H₂

Moles of HCl that react

Avogadro's Number is called the number of particles that make up a substance (usually atoms or molecules) and that can be found in the amount of one mole of said substance. Its value is 6.023×10²³ particles per mole. Avogadro's number applies to any substance.

Then you can apply the following rule of three: if 6.023×10²³ molecules are contained in 1 mole of HCl, then 1.25×10²³ molecules are contained in how many moles of HCl?

amount of moles of HCl= (1.25×10²³ molecules × 1 mole)÷ 6.023×10²³ atoms

amount of moles of HCl= 0.2075 moles

Then, 0.2075 moles of HCl react.

Reaction stoichiometry

By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:

HCl: 2 moles Ba: 1 mole BaCl₂: 1 mole H₂: 1 mole

Mass of barium chloride produced

Then you can apply the following rule of three: if by stoichiometry 2 moles of HCl produce 1 mole of BaCl₂, 0.2075 moles of HCl will produce how many moles of BaCl₂?

[tex]amount of moles of BaCl_{2} =\frac{0.2075 moles of HCl x 1 mole of BaCl_{2} }{ 2moles of HCl}[/tex]

amount of moles of BaCl₂= 0.10375 moles

Being the molar mass of BaCl₂ 208.24 g/mole, then the mass of barium chloride produced is calculated as:

[tex]0.10375 molesx\frac{208.24 grams}{1 mole} =21.6 grams[/tex]

Finally, the mass of barium chloride produced is 21.6 grams.

Problem 57EDraw the Lewis structure for CO with an arrow representing the dipole moment. UseFigure 9.10 to estimate the percent ionic character of the CO bond. Step by step solutionStep 1 of 2Lewis structure of CO:Carbon has four valence electrons and oxygen has six valence electrons. If only one bond wereto be formed between carbon and oxygen atoms, carbon would have five electrons and oxygenwould have seven electrons.The single bond between these two atoms is not sufficient to lead to an octet on each atom . Tocomplete the octet of each atom in CO, we must employ a triple bond .A triple bond is formed bythe six electrons sharing between these two atoms and it is shown as follows.\nThe Lewis structure of CO with an arrow representing the dipole moment.The arrow towards anoxygen atom it represents is a highly electronegative atom.

The formation of molecule can easily be shown by drawing Lewis dot structure. Since atom's Lewis dot structure has three dots. Therefore, in below given ways, we can have Lewis dot structure of CO.

What is Lewis dot structure?

Lewis dot structure is a way to represent the valence electron of an element in the form of dot. These are mainly beneficial in understanding the chemical formula of covalent compound.

Carbon contains four valence electrons, whereas oxygen has six. Carbon has five electrons but oxygen has seven electrons if just one link is established among carbon and oxygen atoms.

The solitary connection formed in between two atoms is insufficient to form an octet on every atom. A triple bond is required to finish the octet of the each atom in CO. The six electrons shared by these two atoms create a triple bond. The dipole moment arrow will point between carbon to oxygen.

Therefore,  in above given ways, we can have Lewis dot structure of CO.
