Explain why the sodium ions and chloride are attracted to each other.

Answers

Answer 1

Answer: The reason a bond is formed between chloride ions and sodium ions is because they have opposite charges. TRUE: the opposite charges attract them together, and this force of attraction is the ionic bond.

Find the number of protons, neutrons, and electrons for carbon-12, carbon-13, and carbon-14 respectively.

Answers

Answer:

A neutral atom of Carbon-12 contains six protons, six neutrons, and six electrons; therefore, it has a mass number of 12 (six protons plus six neutrons).

Carbon-13 (13C) is a natural, stable isotope of carbon with a nucleus containing six protons and seven neutrons and six electrons.

Neutral carbon-14 contains six protons, eight neutrons, and six electrons; its mass number is 14 (six protons plus eight neutrons).

Hope this helps! =D

The number of electrons, protons and neutrons in carbon -12 are all 6 and in carbon-13 they are 6, 6, and 7 respectively and in carbon-14 it is 6, 6,and 8 .

What are isotopes ?

Isotopes are atoms of same element with different mass numbers. Isotopes slightly differ in physical and chemical properties also. Most of the element in periodic table have isotopes however, not all of them are stable and abundant.

The number electrons and protons in a neutral atom is equal. Mass number of an atom is the sum of number of protons and neutrons. In carbon -12, the number of electrons and protons and neutrons is 6 and the number of neutrons in carbon -13 is 7.

The number of electrons and protons is 6 and that of carbon- 14 is 7. Therefore, all these isotopes are having same atomic number but differ in neutrons numbers.

D XY

Answers

Answer:

Its formula is B) XY3,also known as ammonia,because X is hydrogen and Y is nitrogen.

So,yeah the answer is B

Pls mark me as brainliest

The electronic structures of atoms X and Y are shown. X and Y form a covalent compound. The formula is XY₃. The correct option is B.

What are covalent bonds?

Covalent bonds are the strongest bonds present between chemical elements. This bond is formed by sharing electrons between the elements.

Two atoms share electrons with each other and form bonds between them. They are the strongest because there is sharing of electrons between them.

There are five electrons present in the outer shell of the Y atom. There are two atoms more needed to complete the orbital of Y. There is one electron present in the X atom.

Those compounds that are formed by the covalent bond are the strongest compounds. So they are not easy to break them.

Thus, the correct option is B. XY₃.

S + 6 HNO3 --> H2SO4 + 6 NO2 + 2 H2O

In the above equation how many moles of water can be made when 75 moles of HNO3 are consumed?

Answers

2moles of H2O made when 6moles of HNO3 are consumed

Let required moles be x

[tex]\\ \sf\longmapsto \dfrac{2}{6}=\dfrac{x}{75}[/tex]

[tex]\\ \sf\longmapsto \dfrac{1}{3}=\dfrac{x}{75}[/tex]

[tex]\\ \sf\longmapsto x=\dfrac{75}{3}[/tex]

[tex]\\ \sf\longmapsto x=25mol[/tex]

2moles of H2O are made when 6moles of HNO3 are consumed

75 mole of HNO3 produces = [tex]\frac{2}{6}[/tex]× 75 ⇒ 25 moles of water

Limiting Reagent Method

The limiting reagent is the reactant that is completely used up in a reaction and thus determines when the reaction stops.

S + 6 HNO3 --> H2SO4 + 6 NO2 + 2 H2O

6 mole of HNO3 produces = 2 moles of H₂O

1 mole of HNO3 produces = [tex]\frac{2}{6}[/tex] mole of H₂O

∴ 75 mole of HNO3 produces = [tex]\frac{2}{6}[/tex]× 75 ⇒ 25 moles of water

if equations are not balanced,what must you do?

Answers

If a chemical equation is not balanced it implies that either mass has been created or destroyed which is a contradiction to law of conversation of mass which states that matter can niether be created nor destroyed.

In order to balance the chemical equation, you need to make sure the number of atoms of each element on the reactant side is equal to the number of atoms of each element on the product side. In order make both sides equal, you will need to multiply the number of atoms in each element until both sides are equal.

Answers

Explanation:

mole = mass/molar mass

mole of Nacl = mass/mm

molar mass of Nacl = Na + Cl = 23+35=58

mole of NaCl = 29/58

mole of NaCl = 0.5mol

H2SO4 + NaCl ====> HCl + Na2SO4

1. 1. 1. 1

since mole of NaCl is 0.2mol then mole of HCl is also 0.2mol since they are all in the same ratio

mole of HCl = Mole of NaCl = 0.5mol

mass of HCl = ?

molar mass of HCl = H + Cl = 1+ 35=36

mole of HCl = mass /molar mass

0.5= mass/36

mass = 0.5×36 = 18 grams

Answers

B.)because they are packet tight

Answer:

Because they are packet tight.

Explanation:

Solids maintain their volume and shape because they are packet tight.

A solid's particles fit closely together. The forces between the particles are so strong that the particles can not move freely; they can only vibrate. This causes a solid to be a stable, non-compressible shape with definite volume.
