<h3><u>Answer and explanation</u>;</h3>
The balanced chemical equation will be;
NaHCO3 + CH3COOH = CH3COONa + H2O + CO2
After balancing the chemical equation the number of atoms of each element is the same on the reactants and on the products side.
Sodium atoms - 1
Hydrogen atoms - 5
Carbon atoms - 3
Oxygen atoms - 5
Mass of substance in grams 60.1
<span>Chemical Energy is energy stored in the bonds of chemical compounds (atoms and molecules). It is released in a chemical reaction, often producing heat as a by-product (exothermic reaction). Batteries, biomass, petroleum, natural gas, and coal are examples of stored chemical energy and NO i didnt get this off google</span>
Answer:
the gravitational force is proportional to the mass of both interacting objects, bigger objects will attract each other with a greater gravitational force. So the mass of either object increases, the force of gravitational attraction between them also increases.
Answer:
1) 18.91 mL
2) 2.35 %
Explanation:
1. The volume of base that was required is equal to the <em>difference between the reading at the end of the titration and the reading at the beginning</em>:
- V = 20.95 mL - 2.04 mL = 18.91 mL
2. The mass percent can be written as:
- Mass Percent = Mass solute / Total mass * 100%
For this problem:
We<u> input the data and calculate the mass percent</u>:
- % mass = 2.28/96.92 * 100% = 2.35 %
