Answer: C_2H_6 and CH_4

Explanation:

Molecular formula is the chemical formula which depicts the actual number of atoms of each element present in the compound.  

Empirical formula is the simplest chemical formula which depicts the whole number of atoms of each element present in the compound.

C_2H_6 and C_4H_{12} both have empirical formulas of CH_3

C_3H_6O_3 and C_2H_4O_2 both have empirical formulas of CH_2O  

C_2H_6 and CH_4  have empirical formulas CH_3 and CH_4 respectively.

CH_2O and C_3H_6O_3 both have empirical formulas of CH_2O

Answer: D. To decrease the total moles of gas in the system

Explanation:

Any change in the equilibrium is studied on the basis of Le-Chatelier's principle.

This principle states that if there is any change in the variables of the reaction, the equilibrium will shift in the direction to minimize the effect.

when the pressure is increased, , the volume will decrease according to Boyle's Law. Now, according to the Le-Chatelier's principle, the equilibrium will shift in the direction where decrease in pressure is taking place.

As the pressure is directly proportional to the number of moles of gas molecules. So, the equilibrium will shift in a direction where the total moles of gas are decreasing.

Thus the correct answer is to decrease the total moles of gas in the system.

Drag the tiles to the correct boxes. Not all tiles will be used. The oxidation number of oxygen is -2, and that of chlorine is -
Evgen [1.6K]

<u>Answer:</u>

<em>That oxidation number of chlorine is -1 while that of oxygen is -2</em>

<u>Explanation:</u>

When it comes to manganese chloride to stabilize the chlorine Ion. Two manganese ions shall be required. Hence the formula for the compound becomes M_nCl_2 while the formula for manganese (iv) chloride will be M_nCl_4 similarly.

When oxygen and magnesium oxide is considered the Two ions of Manganese will satisfy to ions of oxygen. Which cancels and becomes M_nO while for manganese (iv) oxide  the formula becomes M_nO_2.

Why is 1/t used as a measure of rate of reaction?​
Tpy6a [65]

Answer:

1/t means that the order of reaction is a first order. Meaning that the rate of reaction is directly proportional to reactant concentration. Scientists work with the standard units, therefore 1/t is 1 divide by 1 second.
