Chemistry

timofeeve [1]2 years ago
5 0

Answer: We may only emit about 4% of total emissions, while the natural environment emits the other 96%. But the thing is the natural environment adds and takes out CO2 from the system in roughly equal amounts (at least in the short and medium term). We only add it. We are adding so much of it that the environment can only absorb about half of it, thus the rapid increase in CO2 levels, thus the rapid increase in temperatures.

Brandon is traveling in France. He weighs himself at a health club because he is concerned that he has eaten too many croissants
anastassius [24]

<u>Answer:</u>

<u>For a:</u> Yes, he has gained weight.

<u>For b:</u> The number of onions required is 1.

<u>Explanation:</u>

  • <u>For a:</u>

We are given:

Weight of Brandon checked earlier = 183 lb

Converting this into kilograms, we use the conversion factor:

1 kg = 2.205 lb

So, 183lb\times \frac{1kg}{2.205lb}=83kg

And, weight of Brandon measured at the health club = 85.0 kg

As, the weight at the health club is more than the previous measured weight. So, Brandon has gained weight.

  • <u>For b:</u>

We are given:

Amount of diced onions a recipe calls = 125 g

Mass of 1 onion = 4 oz

Converting the mass of 1 onion to ounces, we use the conversion factor:

1 oz = 28.35 g

So, 4oz\times \frac{28.35g}{1oz}=113.4g

To calculate the number of onions, we use the equation:

\text{Number of onions}=\frac{\text{Mass of onion a recipe calls}}{\text{Mass of 1 onion}}

\text{Number of onions}=\frac{125g}{113.4g}=1.1\approx 1

Hence, the number of onions required is 1.
