23.458 g
<h3>Further explanation</h3>
Given
Reaction
H2SO4 + 2NaNO2 → 2HNO2 + Na2SO4
24.14714 g of Na2SO4
Required
mass of NaNO2
Solution
mol Na2SO4 :
= 24.14714 : 142,04 g/mol
= 0.17
From the equation, mol NaNO2 :
= 2/1 x mol Na2SO4
= 2/1 x 0.17
= 0.34
Mass NaNO2 :
= 0.34 x 68,9953 g/mol
= 23.458 g
Answer:
chemical change because a different solid substance is formed.
Answer:
Carbon enters the atmosphere as carbon dioxide from respiration and combustion. Carbon dioxide is absorbed by producers to make glucose in photosynthesis. Animals feed on the plant passing the carbon compounds along the food chain. ... The animals and plants eventually die.
