Answer:
The answer to your question is 24.325
Explanation:
Data
Magnesium-24 Abundance = 78.70%
Magnesium-25 Abundance = 10.13%
Magnesium-26 Abundance = 11.17%
Process
1.- Convert the abundance to decimals
Magnesium-24 Abundance = 78.70/100 = 0.787
Magnesium-25 Abundance = 10.13/100 = 0.1013
Magnesium-26 Abundance = 11.17/100 = 0.1117
2.- Write an equation
Average atomic mass = (Atomic mass-1 x Abundance 1) + (Atomic mass 2 x
Abundance-2) + (Atomic mass 3 x Abundance 3)
3.- Substitution
Average atomic mass = (24 x 0.787) + (25 x 0.1013) + (26 x 0.1117)
4.- Simplification
Average atomic mass = 18.888 + 2.533 + 2.904
5.- Result
Average atomic mass = 24.325
Answer:
Alcohol will form at more substituted carbon due to carbocation rearrangement so 2-hexanol
Explanation:
Well if it’s acid catalyzed
Answer:
D- beaking bread
Explanation:
The trapped carbon dioxide makes the dough rise, and the alcohol evaporates during the baking process this is an irreversible chemical change.
There are 3 experiments which helps to under water evaporation system.
- Both the temperature of the air surrounding the water and the rate of evaporation increased.
- In the second experiment, we observed an increase in air flow around the water, and this time, the rate of evaporation increased as well.
- In the third and final experiment, we observed an increase in the amount of light in the room, and this time, the rate of evaporation increased as well.
- Because the kinetic energy of a substance can be measured by its temperature, increasing in the temperature or kinetic energy of the air around water will also increase the kinetic energy of the water, which will increase the rate of evaporation.
- It's crucial to have good air flow since it drives water droplets in the air away from you, reducing the amount of humidity in the region. Because there will then be space for the evaporated air or space for the evaporated water to flow into the air, it will then be simpler for the water to really evaporate.
- Water in the presence of sunlight is given extra energy, which increases evaporation.

Explanation:
If the density of the object is more than that of water, it will sink. Otherwise it will float. The density of water is 1 g/mL.
Substance 1,
Mass, m = 450 g, Volume, V = 90 mL
Density = mass/volume
So,
It will sink.
Substance 2,
Mass, m = 35 g, Volume, V = 70 mL
Density = mass/volume
So,
It will float.
Substance 3,
Mass, m = 24 g, Volume, V = 12 mL
Density = mass/volume
So,
It will sink.
