Answer:
Option A
Explanation:
The total heat absorbed during the chemical reaction is the total heat released by the surrounding.
Net change of heat is equal to zero
Hence, the energy liberated from the air or the walls of the containers would be equal to the energy absorbed by the chemical reactions is equal to 100 Kj
Thus, option A is correct
The main constituent of gallstones is cholesterol. Cholesterol may have a role in heart attacks and blood clot formation. Its elemental percentage composition is 83.87% C, 11.99% H, and 4.14% O. It has a molecular weight of 386.64 amu. Empirical formula is C₃H₄O₁ and Molecular formula is 7(C₃H₄O₁).
<h3>What is Empirical Formula ?</h3>
Empirical formula is the simplest whole number ratio of atoms present in given compound.
Element % Atomic mass Relative no. of atoms Simplest whole ratio
C 83.87 12
= 6.98
= 3
H 11.99 1
= 11.09
= 4
O 4.14 16
= 0.25
= 1
Thus the empirical formula is C₃H₄O₁.
<h3>How to find the Molecular formula of compound ?</h3>
Molecular formula = Empirical formula × n
n = 
= 
= 7
Molecular formula = Empirical formula × n
= 7 (C₃H₄O₁)
Thus from the above conclusion we can say that The main constituent of gallstones is cholesterol. Cholesterol may have a role in heart attacks and blood clot formation. Its elemental percentage composition is 83.87% C, 11.99% H, and 4.14% O. It has a molecular weight of 386.64 amu. Empirical formula is C₃H₄O₁ and Molecular formula is 7(C₃H₄O₁).

The chemical reaction that occurs is spontaneous. By the time the battery will recharge the cycle lead sulfate (sulfation) starts to reconvert into sulfuric acid and also with lead. Also, during the reviving procedure as power courses through the water part of the electrolyte and water, (H2O) is changed over into its unique components, hydrogen, and oxygen.
Answer:

Explanation:
Glucose reacts with oxygen do produce carbon dioxide and water:

Given a daily mass of glucose:

Find moles of glucose:

From stoichiometry of this equation, moles of carbon dioxide can be found by multiplying this amount by 6:

Convert this into mass using the molar mass of carbon dioxide:

This is the mass of carbon dioxide per person per day. Multiply by the population and by the number of days to get the total mass:
