Answer:

6.02*1022

Explanation:

I don't know why

Answer:

One mole is equal to 6.02214179×1023 atoms, or other elementary units such as molecules.

Mole measure the number of elementary entities of a given substance that are present in a given sample. Therefore number of atoms in 1.00 moles of Calcium (Ca) are 6.022×10²³ atoms.

The SI unit of amount of substance in chemistry is mole. The mole is used to measure the quantity or amount of substance. We know one mole of any element contains 6.022×10²³ atoms which is also called Avogadro number. Mole is inversely proportional to molar mass.

Mathematically,

mole =given mass ÷ molar mass

Number of atoms = moles ×6.022×10²³ atoms

Substituting the values in above formula we get

Number of atoms = 1 ×6.022×10²³ atoms

Number of atoms 1 mole of calcium = 6.022×10²³ atoms

Therefore, number of atoms in 1.00 moles of Calcium (Ca) are 6.022×10²³ atoms.

Answer:

2NaOH + H₂SO₃ → 2H₂O + Na₂SO₃

Explanation:

When a base as sodium hydroxide (NaOH) reacts with an acid as sulfurous acid (H₂SO₃), the H⁺ of the acid will produce with the OH⁻ of the base H₂O. Te complementary ions will produce the respective salt (Na₂SO₃):

NaOH + H₂SO₃ → H₂O + Na₂SO₃

To balance the sodiums:

2NaOH + H₂SO₃ → H₂O + Na₂SO₃

And the hydrogens:

And this is the complete reaction for this neutralization reaction.

Answer:

pOH = 7.89

Explanation:

As HCl is a strong acid, [H⁺] is equal to the original acid concentration. In other words:

4. Daughter nuclide

5. Fusion

6. Strong nuclear force

Explanation:

4. When an atom of an element decays to a new element, the new element is called the

In a radioactive decay in nuclear physics, the product of the decay which is usually smaller (loss in mass) than its source and may or may not be radioactive is the daughter nuclide. Its source is the parent nuclide

5. Nuclear fusion is the nuclear process that involves the combination of two or more (light) atoms to produce subatomic particles and one or more atomic nucleus accompanied by an emission or absorption of energy due to the difference between the weight of the reactants and the weight of the products

The given reaction, is presented as follows;

³₂He + ¹₁H → ⁴₂He + ⁰₁e

Therefore, given that two atoms, (³₂He and ¹₁H) combine to form one atom (⁴₂He) and a subatomic electron particle (⁰₁e), the reaction is a fusion reaction

6. What keeps a nucleus together

The nucleus is made of neutrons and protons. There is an attractive nuclear force between protons and neutrons and a repulsive electromagnetic force between two or more protons. However, due to the proximity of the of the neutrons and the protons, which are together known as the nucleons, the attractive nuclear force is stronger than the electromagnetic force pushing the protons away from each other and the nucleus is kept together

Therefore, the strong nuclear force keeps the nucleus together.

Answer:

Metamorphic rocks form sedimets

Answer:

A)Trial 1 because the average rate of reaction is lower.

Explanation:

I accidentally gave myself low rating my bad

The statement that best explain which trial has a lower concentration of the reactants is Trial 1, because this reaction lasted for a longer duration than Trial 2.

Chemical reaction refers to reaction that take place between reacting substances in which the chemical substances are transformed to products.

When the concentration of the reactants increases, more molecules tend to interact with each other in order to form new compounds, and the rate of reaction increases. When the concentration of the reactants reduces, there are little of that molecule present, and the rate of reaction decreases

Therefore, The statement that best explain which trial has a lower concentration of the reactants is Trial 1, because this reaction lasted for a longer duration than Trial 2.

Answer: In balancing any chemical equations, the number of atoms of each elements on the reactant side is equals to the number of atoms of the elements on the product side.

Explanation:

Balanced Chemical equations are those equations that has the equal number of atoms of elements on both the reactants and the product sides. To ensure that the chemical equations are correctly balanced the following steps should be observed.

--> identify the elements on the reactant side and on the product side

--> identify the number of atoms of each elements.

--> multiply the number of atoms with the number that will give you a coefficient that will make both the reactant and product sides equal.

--> place the new numbers infront of the elements or compounds.

--> A final check is done to know if the equation is balanced.

From the above steps, the balanced equation of the above questions are listed below:

1.) AlBr3 + 3K ---> 3KBr + Al

2.) FeO + PdF2 --> FeF2 + PdO

3.) P4 + 6Br2 --> 4PBr3

Answer:

.....false

Explanation:

the particles in the air are packed apart whereas the particles in steel are closely packed and sound travel faster in solids than in gasses..

Answer:

False

Explanation:

The speed of sound is quickest in mediums that have their molecules close apart.  The speed of sounds is quickest in solids, followed by liquids, and slowest in gasses.  The close the molecules are together, the quicker sound travels.  The sound would travel faster in the steel than in the air.

This is due to the fact that sound waves are compression waves.  This means that they rely on the way molecules collide with one another and act sort of like a spring.  

Fun fact: In the old days, people used to put their ears to the train tracks to see if a train is coming.  Sound moves so fast in metal that they can sense the vibrations miles before the train arrived.

Explanation:

Wasting household water does not ultimately remove that water from the global water cycle, but it does remove it from the portion of the water cycle that is readily accessible and usable by humans. Also, "wasting" water wastes the energy and resources that were used to process and deliver the water.

Answer:

I feel like there should be more parts to this question but I think it depends on how you got your water. If you waste water after you got it from a local stream yourself, you wasted your body energy but no real electricity of any kind. If the water is processed and filtered and you end up wasting it, I guess it counts as energy being wasted too? Because the sole purpose was to bring you clean water but you didn't utilize it

Promoters are substances that increase the catalytic activity, even though they are not catalysts by themselves.

Inhibitors are sometimes referred to as "negative catalysts" since they decrease the reaction rate.
