Answer:- 2,1

Explanations:- Water is H_2O and from it's formula it is clear that the ratio of H to O moles or atoms is 2:1 means two hydrogen atoms for each oxygen atom. No matter what amount of water we have, the ratio of H atoms to O atoms is always same.

Hence, the answer is 2,1.

The ratio of H and O atoms in water is 2: 1

<h3>Further explanation</h3>

In a chemical compound, there is the term atom, element, and compound itself.

  • 1. An atom is the smallest material consisting of a nucleus, which contains protons, neutrons, and electrons,
  • 2. Elements can be atomic or molecular elements. It can be an atom such as Ag (argon), Fe (Iron). When in the form of molecules it is a combination of atoms of the same type, for example, O₂,
  • 3. A molecule is a combination of elemental atoms, can be two.

- If it consists of atoms of the same element called an Element molecule, For example, N₂, Cl₂

- If it consists of atoms of different kinds of elements called molecular Compounds, for example, H₂SO₄, NaOH

There are numbers in the chemical formula of the compound:

  • 1. Numbers indicate the number of atoms written after the element symbol
  • 2. The number after the parenthesis shows the number multiplied by the number of atoms in the parenthesis.
  • 3. The number before the chemical formula shows the number of molecules behind it. Usually used in the reaction equation

Generally, there are 2 formulas used:

  • The empirical formula (RE) is the smallest atomic ratio of the constituent elements.
  • Molecular formula (RM) is a formula that shows the number of atomic elements that make up a compound.

(RE) n = RM

In 1 water molecule that has the H₂O formula, according to the numbers in this molecular formula, it is found that:

there are 2 H atoms and 1 O atom, so the ratio of the atoms is:

H: O = 2: 1

Please help with chemistry question... It would help me tremendously and if you can, please show work :)?
Alexxandr [17]

Answer:

5.06 atm

Explanation:

Step 1:

Data obtained from the question. This includes:

Mass of S2O = 175g

Volume (V) = 16600 mL

Temperature (T) = 195°C

Pressure (P)

Step 2:

Determination of the number of mole of S2O in 175g of S2O.

Mass of S2O = 175g

Molar Mass of S2O = (32x2) + 16 = 64 + 16 = 80g/mol

Number of mole of S2O =.?

Number of mole = Mass/Molar Mass

Number of mole of S2O = 175/80

Number of mole of S2O = 2.1875 moles

Step 3:

Conversion to appropriate units.

It is essential to always express the various variables in the right units of measurement in order to obtain the desired answer in the right units.

For volume:

1000mL = 1L

Therefore, 16600mL = 16600/1000 = 16.6L

For temperature:

Temperature (Kelvin) = temperature (celsius) + 273

Temperature (celsius) = 195°C

Temperature (Kelvin) = 195°C + 273 = 468K

Step 4:

Determination of the pressure.

The pressure can be obtained by the application of the ideal gas equation. This is illustrated below:

Volume (V) = 16.6L

Temperature (T) = 468K

Number of mole (n) = 2.1875 moles

Gas constant (R) = 0.082atm.L/Kmol

Pressure (P) =

PV = nRT

P x 16.6 = 2.1875 x 0.082 x 468

Divide both side by 16.6

P = (2.1875 x 0.082 x 468) /16.6

P = 5.06 atm

Therefore, the pressure is 5.06 atm

if a gas sample in a balloon occupies 1.5 L at atmospheric pressure, what would be the pressure (in mmHg) if the volume was redu
Nata [24]

Answer:

1425 mmHg.

Explanation:

The following data were obtained from the question:

Initial volume (V1) = 1.5 L

Initial pressure (P1) = 1 atm

Final volume (V2) = 0.8 L

Final pressure (P2) =?

Next, we shall determine the final pressure of the gas by using the Boyle's law equation as follow:

P1V1 = P2V2

1 × 1.5 = P2 × 0.8

1.5 = P2 × 0.8

Divide both side by 0.8

P2 = 1.5/0.8

P2 = 1.875 atm

Finally, we shall convert 1.875 atm to mmHg.

This can be obtained as follow:

1 atm = 760 mmHg

Therefore,

1.875 atm = 1.875 × 760 = 1425 mmHg.

Therefore, the new pressure of the gas is 1425 mmHg.
