The only one I know is NaC2HO4.

There is Sodium, Carbon, Hydrogen and Oxygen.

1 atom in sodium, 2 atoms in carbon, 1 atom in hydrogen and 4 atoms in oxygen completeting the total of 8 atoms in this element.

The elements are the simplest chemical forms and they cannot be broken down through chemical reactions. There are many elements in the given formulas.

The elements are defined as those substances whose atoms all have the same number of protons. The elements are considered as the building blocks of matter. Each element has an atomic number and a symbol.

Each atom is regarded as an element. The elements create bonds to form molecules. The isotopes are the elements with the same atomic number but different mass numbers.

NaC₂HO₄  - 'N' , 'C', 'H','O'

H₂F₅BLi - 'H','F','B','Li'

He₂PSO₄ - 'He', 'P','S','O'

He₂O₄PH - 'He', 'O','P','H'

The atomic number of fluorine is 9.

The charge number of an atomic nucleus is known as the atomic number or nuclear charge number of a chemical element. It will be is equal to the proton number of every atom of that element, for ordinary nuclei. Atomic number helps to getting information of elements with the aid of periodic table.

Atomic number = count of proton

It is known that the atomic number of fluorine is 9 . therefore, the answer will be atomic number.

Copper is a metal made up of copper atoms closely packed together. As a result, the electrons can move freely through the metal. For this reason, they are known as free electrons. They are also known as conduction electrons because they help copper be a good conductor of heat and electricity.

Explanation:

Answer:

When the volume decreases, the pressure increases. This shows that the pressure of a gas is inversely proportional to its volume. This is shown by the following equation - which is often called Boyle's law. ... It means that for a gas at a constant temperature, pressure × volume is also constant.

Answer:

When the volume decreases, the pressure increases. This shows that the pressure of a gas is inversely proportional to its volume. ... It means that for a gas at a constant temperature, pressure × volume is also constant.

Explanation:

Answer:

Increase

Less/low number

Lessen

Explanation:

Increase > Increase in temperature cause increase in volume.

Less/low number > As volume increases the number of particles to be adjusted in the same space will be lesser than before.

Lessen> At constant pressure as increase in temperature cause increase in volume so the density will lessen due to increase in volume. Density equation is given below.

Density = mass /volume

If volume increases density will get lowered.

Answer: Iron

Explanation: does not react with water, but hydrochloric acid will dissolve them, displacing the hydrogen from the HCl. Iron reacts with hydrogen chloride to produce iron chloride, FeCl2 — sometimes known as ferrous chloride.

To solve such this we must know the concept of chemical reaction. Iron is the metal, which dissolves in hydrochloric acid to produce hydrogen gas, but does not react with steam.

Chemical reaction is a process in which two or more than two molecules collide in right orientation and energy to form a new chemical compound. The mass of the overall reaction should be conserved. There are so many types of chemical reaction reaction like combination reaction, double displacement reaction.

When metals react with acid the liberation of hydrogen gas take place.  Metal which is at top of reactivity series react with both acid and steam or liquid water. Iron is the only metals which dissolves in hydrochloric acid to produce hydrogen gas, but does not react with steam or liquid water.

Therefore, iron is the metal, which dissolves in hydrochloric acid to produce hydrogen gas, but does not react with steam.
