Why is lead(II) nitrate: “Pb(NO3)2” and not “Pb3NO2”?

Just a bit confused because it looks a bit funny compared to how I learned how to write compounds.

Answers

Answer 1

Explanation:

this is because the combining capacity, ie valency, of Pb is 2 of which NO3 is 1. So, when they will combine by cross method, the compound become Pb(NO3)2 (lead II nitrate).

hope this helps you.

What is the molarity of a NaOH solution if 48.0 mL of a 0.220 M H2SO4 solution is required to neutralize a 25.0-mL sample of the NaOH solution?

Answers

Answer:

Molarity NaOH = 0.85M (2 sig figs)

Explanation:

48.0ml(0.220M H₂SO₄) + 25ml(Xmolar NaOH)H₂SO₄ + 2NaOH => Na₂SO₄ + 2H₂O

2(molarity x volume) H₂SO₄ = (molarity x volume) NaOH

2(0.220M x 48.0ml) = 25.0ml x Molarity NaOH

Molarity NaOH = 2(0.220M x 48.0ml)/25.0ml = 0.8448M ≅ 0.85M (2 sig figs)

Question 1 (5 points)
(04.01 LC)
Based on the law of conservation of mass, which of the following statements is correct? (5 points)
a
Matter is neither created nor destroyed.
b
Matter can be created but it cannot be destroyed.
The total mass of substances before a reaction is less than the total mass after a reaction.
The total mass of substances before a reaction is greater than the total mass after a reaction.

Answers

A
matter can not be created or destroyed

Matter is neither created nor destroyed. Therefor, option (A) is correct.

What is The Law of Conservation of Mass?

The Law of Conservation of Mass is a fundamental principle in science that states that matter cannot be created or destroyed in a chemical reaction, only transformed from one form to another. This means that the total mass of the reactants in a chemical reaction must be equal to the total mass of the products.

The Law of Conservation of Mass was first introduced by Antoine Lavoisier, a French chemist, in the 18th century. The law has been extensively tested and verified through numerous experiments in the field of chemistry. It is an essential concept for understanding the behavior of matter in chemical reactions and for the development of technologies that depend on chemical reactions, such as energy production, medicine, and materials science.

Answers

The products of the reaction would be NaOH and HF

From the question,

We are to determine the products of the reaction between NaF and water in the same manner as the given reaction.

To determine the other product, we will write the equation for the reaction

The equation for the reaction is

NaF + H₂O → NaOH + HF

Hence, the products of the reaction would be NaOH and HF.

Why is it important that you not breathe on the baking soda test?

Answers

Breath will warm up the test by several degrees and cause the products to decompose. Breath contains water vapor

Baking soda is a salt of sodium and bicarbonate ions. In a soda test, the breath will raise the temperature as it contains water vapor and decomposes the soda.

What is the baking soda test?

The baking soda is also called sodium bicarbonate, and the test uses sodium bicarbonate as a reactant. It is also a leavening agent that is used in the preparation of food.

Breath contains some amount of water vapor that alters the test by diluting it and resulting in the clouding of the test. The water vapor decomposes the baking soda and alters the test results.

Therefore, breath contains water vapor.

(Hope this helps can I pls have brainlist (crown)☺️)

Explanation:

Because the atoms in metals form a matrix through which outside electrons may easily travel, metals are good conductors of electricity and heat. They generate a sea of electrons around the positive nuclei of the interacting metal ions, rather than circling their particular atoms.

The free flow of shared electrons can carry an electric current through a metal. Carbon atoms join with iron atoms to create bonds.
