Answer: Option (D) is the correct answer.

Explanation:

A synthesis reaction is defined as the reaction in which two molecules or atoms combine together to result in the formation of a compound.

For example, Sodium + Chloride \rightarrow \text{Sodium chloride}, is a synthesis reaction.

Decomposition reaction is a reaction in which a reactant or substance breaks into two or more substances.

For example, \text{Sodium chloride} \rightarrow Sodium + Chloride, is a decomposition reaction.

In a single replacement reaction, an element replaces one atom from a compound.

For example, Zn+ CuCl_{2} \rightarrow ZnCl_{2} + Cu

Thus, we can conclude that the chemical equation sodium + chlorine \rightarrow \text{sodium chloride} represent synthesis reaction.

A sample of carbon dioxide at RTP is 0.50 dm3. How many grams of carbon dioxide do we have?
prohojiy [21]

Answer:

0.924 g

Explanation:

The following data were obtained from the question:

Volume of CO2 at RTP = 0.50 dm³

Mass of CO2 =?

Next, we shall determine the number of mole of CO2 that occupied 0.50 dm³ at RTP (room temperature and pressure). This can be obtained as follow:

1 mole of gas = 24 dm³ at RTP

Thus,

1 mole of CO2 occupies 24 dm³ at RTP.

Therefore, Xmol of CO2 will occupy 0.50 dm³ at RTP i.e

Xmol of CO2 = 0.5 /24

Xmol of CO2 = 0.021 mole

Thus, 0.021 mole of CO2 occupied 0.5 dm³ at RTP.

Finally, we shall determine the mass of CO2 as follow:

Mole of CO2 = 0.021 mole

Molar mass of CO2 = 12 + (2×16) = 13 + 32 = 44 g/mol

Mass of CO2 =?

Mole = mass /Molar mass

0.021 = mass of CO2 /44

Cross multiply

Mass of CO2 = 0.021 × 44

Mass of CO2 = 0.924 g.

How many moles are in 48.0g of H2O2?
Tju [1.3M]

Answer:

1.41 moles H2O2(with sig figs)

Explanation:

okay so what is the molar mass of H2O2= (1.008 g/mol)2+(16.00g/mol)2= (2.016+ 32.00) g/ mol

= 34. 02 g/mol

48.0g H2O2* 1 mol H2O2/ 34.02 g H2O2= 1.41 mol H2O2
