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

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.

1 silver, 1 nitrogen and 3 oxygen

Subscripts show the number of atoms of each element in a compound

There is no subscript after Ag which shows there is only one silver atom. There is no subscript after N which shows there is only one nitrogen atom. However, there is a 3 in the subscript after O which shows there are 3 oxygen atoms

Answer:

(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.

Explanation:

this is the correct answer

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.

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.

Answer:

In chemistry, the law of conservation of mass states that the mass of the products (the chemical substances created by a chemical reaction) will always equal the mass of the reactants (the substances that make the chemical reaction). Think of it as being similar to balancing an algebraic equation.

Explanation:

(winks and runs off)

Answer:

Mass cannot be created or destroyed.

Explanation:

        Conservation of mass is "a principle stating that mass cannot be created or destroyed" (Oxford Languages).

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)

From the information presented in the question, the number of molecules present of water present is obtained 2.41 × 10^21 molecules.

From the information we have;

Volume of the damp air =  1 L

Pressure of the damp air =  741.0 torr or 0.975 atm

Temperature of the gas = 20 oC + 273 = 293 K

R = 0.082 atm LK-1mol-1

Number of moles = ?

n =PV/RT

n = 0.975 × 1/0.082 ×  293

n = 0.041 moles

Volume of water vapor = 1 L

Temperature of water = -10 oC + 273 = 263 K

Pressure of the gas = 607.1 torr or 0.799 atm

R = 0.082 atm LK-1mol-1

n= PV/RT

n = 0.799 × 1/ 0.082 × 263

n = 0.037 moles

Number of moles of water = 0.041 moles -  0.037 moles = 0.004 moles

If 1 mole = 6.02 × 10^23 molecules

0.004 moles = 0.004 moles × 6.02 × 10^23 molecules/1 mole

= 2.41 × 10^21 molecules

Answer:

Kinetic energy depends on the velocity of the object squared

Explanation:

Kinetic energy depends on the velocity of the object squared. This means that when the velocity of an object doubles, its kinetic energy quadruples. ... Kinetic energy must always be either zero or a positive value. While velocity can have a positive or negative value, velocity squared is always positive.
