Answer: 2.7 grams
Explanation:
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.
Given: mass of sodium hydrogen carbonate = 3.4 g
mass of acetic acid = 10.9 g
Mass of reactants = mass of sodium hydrogen carbonate+ mass of acetic acid = 3.4 + 10.9= 14.3 g
Mass of reactants = Mass of products in reaction vessel + mass of carbon dioxide (as it escapes)
Mass of carbon dioxide = 14.3 - 11.6 =2.7 g
Thus the mass of carbon dioxide released during the reaction is 2.7 grams.
<span>The answer to your question is letter A. study how cholesterol is broken down in the body. Biology is a study of life which deals with cells, organelles, and other essential parts of the body or organism. Chemistry is a study about chemicals and how it reacts to natural state. In studying about cholesterol in the body, the presence of biologist and chemists will study how the body reacts with the chemicals and substances that were stored in the cholesterol.</span>
Answer:
The final volume is 1.1 L.
Explanation:
Given data:
Initial pressure of gas = 125 KPa
Final pressure of gas = 375 KPa
Initial volume = 3.3 L
Final volume = ?
Solution:
The given problem will be solved through the Boly's law,
"The volume of given amount of gas is inversely proportional to its pressure by keeping the temperature and number of moles constant"
Mathematical expression:
P₁V₁ = P₂V₂
P₁ = Initial pressure
V₁ = initial volume
P₂ = final pressure
V₂ = final volume
Now we will put the values in formula,
P₁V₁ = P₂V₂
125 Kpa × 3.3 L = 375 Kpa × V₂
V₂ = 412.5 KPa. L/375 Kpa
V₂ = 1.1 L
The volume of gas is reduced to the 1.1 L because of increasing pressure.
