Sodium carbonate (na2co3) is used to neutralize the sulfuric acid spill. how many kilograms of sodium carbonate must be added to

gayaneshka [121]

THe balanced chemical reaction would be:
Na2CO3 + H2SO4 = Na2SO4 + H2O + CO2

We first convert the mass of sulfuric acid solution to moles by the molar mass. Then, we relate H2SO4 with Na2CO3 from the reaction. We do as follows:

6.05×10^3 kg H2SO4 ( 1 kmol / 98.08 kg) ( 1 kmol Na2CO3 / 1 kmol H2SO4 ) ( 105.99 kg / kmol ) = 6537.92 kg Na2CO3 needed

What is the solution to the problem rounded to the correct number of significant figures? 8.01 × 4.1 = ? A. 32.8 B. 32.84 C. 32.

kicyunya [14]

Answer: The correct option is Option D.

Explanation:

Significant figures are defined as the figures that represent the digits of a number which carry an important contribution to the numerical value, starting with the first non-zero digit. For Example: 105.268 has 6 significant figures because every digit carry its own contribution towards the numerical value.

Whenever there is multiplication, the answer will contain the same number of significant figures as there are in the least precise numerical value.

Significant figures in 8.01 are 3 and that in 4.1 are 2.

So, the answer of these two numerical value will contain 2 significant figures.

$8.01\times 4.1=32.841\approx 33$

Hence, the correct option is Option D.
