What is the pressure of nitrogen in atmospheres of a sample that is at 745 mmHg?

Chemistry
1 answer:
Lelu [443]3 years ago
4 0

The correct answer is 0.9803 atm

Given, pressure of nitrogen =  745 mmHg

Conversion factor: 760 mmHg = 1 atm

Converting 745 mmHg to 1 atm

745 mmHg x ( 1 atm / 760 mmHg) = 0.9803 atm

So is the pressure of nitrogen is  0.9803 atm

Hello! Id like if someone could tell me this answer, thank you so much!
DaniilM [7]

Answer:

Option D. ZnCl₂ and H₂

Explanation:

From the question given above, the following equation was obtained:

2HCl + Zn —> ZnCl₂ + H₂

Products =?

In a chemical equation, reactants are located on the left side while products are located on the right side i.e

Reactants —> Products

Now, considering the equation from the question i.e

2HCl + Zn —> ZnCl₂ + H₂

The products are ZnCl₂ and H₂ because from our discussion above, we said that products are only located on the right side of chemical equation.

Thus, option D gives the correct answer to the question.

14. All the following are necessary parts of a neutralization reaction except A. an indicator. B. a salt. C. water. D. an acid.
ValentinkaMS [17]

The correct answer is <em>B. a Salt </em><em>because The reaction of an acid and a base is called a neutralization reaction because the properties of both the acid and base are diminished or neutralized when they react. A neutralization reaction is a reaction of an acid with a base in aqueous solution to produce water and a salt, as shown by the following equation:</em>

<em>acid + base → salt + water</em>

Are ions always smaller than their neutral atoms
Arturiano [62]

Answer:

The negative ion is larger than the original atom. but the same number of positive protons, the size of the ionic radius will increase. When an atom has its electrons attracted to another atom it becomes a positive ion. The positive ion is smaller than the original atom.

What is the identity of the resulting atom
Gre4nikov [31]
Remember that the number of protons in the nucleus determines an element's identity. Chemical changes do not affect the nucleus, so chemical changes cannot change one type of atom into another. The number of protons in a nucleus does change sometimes, however. The identity of the atom, therefore, changes.
