The mass of bismuth fluoride formed is 41909.99 g
Explanation:
According to the law of conservation of mass, the total mass of the reactants in a chemical reaction must be equal to the total mass of the products after the reaction.
In this problem, we have:
We also have:
So, the total mass of the reactants is:
And therefore, the mass of bismuth fluoride formed is also 41909.99 g.

Rock 1000 0.5
Pillow 200 10
Bottle of soda 2000 2
Loaf of bread 100 1
rock and bottle of soda
loaf of bread and rock
loaf of bread and pillow
bottle of soda and loaf of bread
Explanation:
The density of the material is given by,
Density =
Case 1: Rock
Density =
Density =
Density = 2000
Case 2: Pillow
Density =
Density =
Density = 20
Case 3: Bottle of Soda
Density =
Density =
Density = 1000
Case 4: Load of bread
Density =
Density =
Density = 100
Thus, rock and bottle of soda has maximum density.
2.Chemical energy is converted to mechanical energy.
3. Chemical energy is converted to heat energy.
4. Chemical energy is converted to mechanical and kinetic energy.
the correct answer is 1. Chemical energy is converted to mechanical and heat energy.
When the boy eats apple, the chemical energy of the apple first converted in the heat energy in the process of digestion, which maintains our body temperature, than the body of the boy converts the heat energy into mechanical energy.
Therefore the correct option is 1.
Answer:
Chemical energy is converted to mechanical and heat energy.
