Answer:

205 calories.

Explanation:

According to the USDA, "Carbohydrates provide 4 calories per gram, protein provides 4 calories per gram, and fat provides 9 calories per gram." 9 grams of fat at 9 calories per equals 81 calories + 6 grams of protein at 4 calories per gram which equals 24 calories + 25 grams of carbohydrate at 4 calories per gram which is equal to 100 calories.

Total that all up and you get 81 cal + 24 cal + 100 cal=205 calories.

I don't know what kind of course this is for, but if they are incredibly picky, what we refer to as "calories" are actually kilocalories, which are equal to one thousand "real" calories each. However, I'm very confident that the correct answer is 205 calories.

What is the best way to eliminate poison ivy?
antoniya [11.8K]
What poison ivy looks like:
Each leaf has 3 little leaflets. It tends to grow off-white berries on the leaves in the early fall, and grows yellow-green flowers in the spring. 

Treating poison ivy:
If you have a rash from poison ivy, it is recommended to rinse your skin off with lukewarm water immediately after you notice the rash. 
Make sure to wash your clothing since the oil from the plant can stick to your clothing.
Do not scratch at the rash, as scratching will cause an infection.
If blisters appear on your skin, do not mess with them as it can prevent infection.

How to kill poison ivy:
If you find the plant, do not pull or burn it. Even if you pull it, it will still grow out of the ground since you did not eliminate the roots of it. Burning it can release <span>urushiol into the air which can be harmful.
</span>It is recommended to use a specialized weed killing spray. Always look at the ingredients in the spray and look for: Triclopyr, which fights through the surface of the plant, and also <span>glyphosate, that helps kill the roots of the plant.
</span>Once you use a spray, it will take 1-2 weeks for it to die. It will eventually turn yellowish-brownish.

Important:
 Poison ivy contains urushiol which can cause allergic reaction.
Burning poison ivy releases urushiol into the air which can also cause allergic reaction and can be harmful.

A student increases the temperature of a 200cm3 balloom from 60 degress C to 180 degrees C. What will the new volume of the ball
kkurt [141]

Answer:

The new volume of the balloon is 600cm³

Explanation:

Given parameters:

Initial Volume, which is V₁ = 200cm³

Initial temperature, T₁ = 60°C

Final temperature T₂ = 180°C

Final Volume V₂ =?

To solve this kind of problem, we apply one of the gas laws that shows the relationship between volume and temperature.

This law is the Charles law, it states that " the volume of a fixed mass of a gas is directly proportional to its absolute temperature if pressure is constant".

It is simply expressed as:

V₁/T₁ = V₂/T₂

Since our unknown is V₂, we make it the subject of the expression given above:

V₂ = V₁T₂/T₁

Now input the corresponding values and solve:

V₂ = 200 x 180 / 60

V₂ = 36000/60

V₂ = 600cm³

The new volume of the balloon is 600cm³
