Why don’t all salts make a one-to-one ratio?

Answers

Answer:

because all types of salts are made up of different substrances

All salts do not make a one-to-one ratio because the salts are composed of different ions that combine together in different ratios.

A salt is an ionic substance. Salts are formed by combination of a cation and and anion.

Different salts are comprised of different ions. The ratios in which the ions combine in each salt is not the same.

Hence, all salts do not make a one-to-one ratio because the salts are composed of different ions that combine together in different ratios.

protons

Answers

Protons

Protons are the subatomic particle that determines the identity of an element.

Answer:

Explanation:Protons and neutrons are located in the nucleus of an atom and determine the mass of an atom. Protons have a positive electrical charge and electrons have a negative electrical charge. Atoms that have the same number of protons and electrons do not have an electrical charge.

How much energy is needed to turn 450 g of zinc into liquid metal at its melting point? (Round your answer to the nearest tenth) *

Answers

Answer:

Explanation:

Latent heat of fusion of zinc = 7.322 kJ / mol

molecular weight of zinc = 65 g

450 gram = 450 / 65 = 6.92 mole

Heat required to melt 450 g of zinc = 6.92 x 7.322 kJ

= 50.67 kJ .

= 50.7 kJ .

Problem Page Decide whether these proposed Lewis structures are reasonable. proposed Lewis structure Is the proposed Lewis structure reasonable? Yes. No, it has the wrong number of valence electrons. The correct number is: No, it has the right number of valence electrons but doesn't satisfy the octet rule. The symbols of the problem atoms are:* Yes. No, it has the wrong number of valence electrons. The correct number is: No, it has the right number of valence electrons but doesn't satisfy the octet rule. The symbols of the problem atoms are:*

Answers

The question is incomplete, the complete question is shown in the image attached.

Answer:

1) No, it has the right number of valence electrons but does not satisfy the octet rule.

2) Yes

3) No, it has the wrong number of valence electrons, the correct number is 16

Explanation:

If we look at the first structure in the image(HCN), it easy to see from inspection that nitrogen has three valence electrons as it is normally supposed to have. However, if we count all the electrons around nitrogen, we will notice that they are six instead of eight. Thus nitrogen has not satisfied the octet rule here.

The structure HBr satisfies the octet rule, hence it is a reasonable Lewis structures for the compound shown.

CO2 has 16 valence electrons but the structure shown contains about 20 valence electrons hence it is not a reasonable Lewis structure for the compound.

Yes, in HCO⁺ the proposed lewis structure is reasonable.

No, COCl₂ has the wrong number of valence electrons.

No, OH⁻ has the right valence electron but does not obey the octet rule.

The correct structure for the question can be seen in the image attached below.

In the proposed structure, the number of valence electrons in HCO⁺ is: ( 1 + 4 + (6-1) ) = 10e⁻

Thus, the atoms obey the octet rule and the number of calculated valence electrons corresponds with what we have in the given structure.

Yes, the structure is correct and reasonable.

In COCl₂, the central carbon bonding to the oxygen is supposed to be doubly bonded and not singly bonded.the number of valence electron in COCl₂ is: ( 4 + 6 + (7 × 2)) = 24e⁻

The calculated number of valence electrons is different from the given structure of 26e⁻, so we can say No, it has a wrong number of valence electrons.

In the third structure, oxygen is supposed to have three lone pairs of electrons in order to obey the octet rule.the number of valence electrons in the structure is: (6 + (1+1) = 8e⁻

But both H, as well as, O do not obey the octet rule. Therefore, we say No, it has the right number of valence electron but do not obey the octet rule.

A brick delivery truck parks on a roadside scale that measures 4 m by 6 m. If the brick truck weighs 60 000 N, what pressure does the scale put on the spring below?

Answers

Explanation:

Area = Length × Breadth

A = 4 × 6

A = 24m square/ 24m sq.

Force = Pressure × Area

Force = 60,000 N/ 60,000 Newton

Pressure = Force/ Area

P = 60,000/24

P = 2500 Pa

Which two parts are needed to make a neutral atom of nitrogen A. Electron clouds with a total of 14 electrons B. Electron cloud is a total of seven electrons C. A nucleus with seven protons and seven neutrons D. A nucleus with three protons and four neutrons

Answers

Answer:

B. Electron cloud is a total of seven electrons

C. A nucleus with seven protons and seven neutrons

Explanation:

An atom is consist of three subatomic particles: electron, proton, and neutron. Proton are positively charged particles and neutron have neutral charge, they both are present inside the nucleus in the center of the atom whereas electrons are negatively charged and surround the nucleus in a definite orbit.

Nitrogen is an element with 7 electrons in its outer orbit. As electrons are negatively charged so nitrogen atom will require 7 protons inside the nucleus to form a neutral atom of nitrogen. So, A neutral atom of nitrogen will consist of 7 electrons and 7 protons.

As, neutron has neutral charge so it will not affect the composition of neutral atom of nitrogen.

Hence, the correct options are:

"B. Electron cloud is a total of seven electrons

C. A nucleus with seven protons and seven neutrons ".
