Explanation:

A hydrogen atom has an atomic number of 1.

So it's proton number will always be 1.

A neutral hydrogen atom does not have any charge.

So it has the same amount of electrons as protons, which turns out to be also 1.

A neutral hydrogen atom has an atomic mass of ≈1.00794amu≈1amu.

To find the amount of neutrons, we take the proton number and subtract it from the mass number.

1−1=0

So a neutral hydrogen atom has no neutrons.

In summary,

A hydrogen atom has

1 proton

1 electron

0 neutrons

another way of explaining:

The number of protons is the atomic number, and the number of protons plus neutrons is the atomic mass. For hydrogen, the atomic mass is 1 because there is one proton and no neutrons. For helium, it is 4: two protons and two neutrons

Answer:

Oxygen is an element.

Explanation:

Out of the choices listed, oxygen is the only element. The other choices are incorrect because air is a mixture of nitrogen, oxygen, carbon dioxide, water vapors, and some other gases; water is a compound of hydrogen and oxygen; and sodium chloride is a compound of sodium and chloride ions; meanwhile, oxygen is a pure element.

Enzymes are biological catalysts that promote several reactions in the body. The spoilage of food is affected by the enzymes present in food. They act slowly, causing the food to spoil.  

However, there are two way to protect a food from spoilage. These are;

These processes slow down the action of these enzymes that are responsible for the spoilage of food thereby enabling the food to last longer.

Answer:

We assume that there is 100g of the compound (because it makes it easier to calculate) and we turn the percentages into grams.

2% of Hydrogen = 2g of H

32.7% of Sulfur = 32.7g of S

65.3% of Oxygen = 65.3g of O

Now we change the mass of these elements to moles by dividing the mass by the molar mass (which is the value of atomic mass on your periodic table)

2g/1.01g = 1.98 mol

32.7g/32.06g = 1.02 mol

65.3g/16g =4.08 mol

divide all these mol values by the smallest mol value, which is 1.02. (Round the values to whole numbers)

1.98/1.02 = 2 (rounded) of Hydrogen

1.02/1.02 = 1 of Sulfur

4.08/1.02 = 4 of Oxygen

H2SO4 (also known as sulphuric acid) is your empirical formula.

Answer:

Hence, the wavelength of the photon associated is 1282 nm.

Explanation:

The molality of the solution is 1.4 moles per kilogram (molal).

The molality of the solution is equal to the number of moles of sugar (solute) divided by the number of kilograms of water (solvent). Hence, the molality is determined below:

[tex]m = \frac{3.5\,mol}{2.5\,kg}[/tex]

[tex]m = 1.4\,\frac{mol}{kg}[/tex]

The molality of the solution is 1.4 moles per kilogram (molal).

According to the forces of attraction, the most likely state of matter of the substance mentioned is liquid.

Matter in chemistry, is defined as any kind of substance that has mass and occupies space that means it has volume .Matter is composed up of atoms which may or not be of same type.

Atoms are further made up of sub atomic particles which are the protons ,neutrons and the electrons .The matter can exist in various states such as solids, liquids and gases depending on the conditions of temperature and pressure.

The states of matter are inter convertible into each other by changing the parameters of temperature and pressure.According to law of conservation of matter , matter can neither be created nor destroyed only its state changes .

Answer:

Plant cells and animal cells are both eukaryotic cells. They both have a nucleus, Golgi complex, endoplasmic reticulum, ribosomes, mitochondria, cytoskeleton and cell membrane. Only plants cells have a vacuole, cell wall and chloroplast, while animal cells have cilia, centrioles and lysosomes which plant cells don't usually have. Because of their cell walls plant cells are in rigid rectangular shapes while animal cells have looser round shapes. The main difference in their functions is that animals don't produce their own food while plan cells do.

The mass of ferric nitrate, Fe(NO₃)₃ produced from the reaction given the data is 5792.44 g

2Fe + 6HNO₃ –> 2Fe(NO₃)₃ + 3H₂

Molar mass of Fe = 56 g/mole

Mass of Fe from the balanced equation = 2 × 56 = 112 g

Molar mass of Fe(NO₃)₃ = 56 + 3[14 + (16×3)] = 242 g/mole

Mass of Fe(NO₃)₃ from the balanced equation = 2 × 242 = 484 g

SUMMARY

From the balanced equation above,

112 g of Fe reacted to produce 484 g of Fe(NO₃)₃

From the balanced equation above,

112 g of Fe reacted to produce 484 g of Fe(NO₃)₃

Therefore,

1340.4 g of Fe will react to produce = (1340.4 × 484) / 112 = 5792.44 g of Fe(NO₃)₃

Thus, 5792.44 g of Fe(NO₃)₃ were obtained from the reaction
