Answer:

16.6dL

Explanation:

First, we need to convert 1.66mL dL this can be achieved by doing the following:

1mL = 0.01dL

1.66mL = 1.66 x 0.01 = 0.0166dL

From the question, we were told that the volume 1 drop of blood = 1.66mL i.e 0.0166dL.

Therefore 1000 drops of blood will be = 0.0166 x 1000 = 16.6dL

Which law states that the volume and absolute temperature of a fixed quantity of gas are directly proportional under constant pr
Delvig [45]
<h2>Hello!</h2>

The answer is: Charle's Law.

<h2>Why?</h2>

The law that states that the volume and absolute temperature of a fixed quantity of gas (ideal gas) are proportional under constant pressure is the Charle's Law, also known as the law of volumes.

The law describes how a gas kept under constant pressure tends to expand when the temperature increases and it's described by the following equation:

\frac{V}{T}=k

Where,

V=Volume\\T=Temperature\\k=constant

Also, to describe the relationship between two differents volumes at different temperatures, we have:

\frac{V_{i}}{T_{i}}=\frac{V_{f}}{T_{f}}

Where,

V_{i}=InitialVolume\\T_{i}=InitialTemperature\\V_{f}=FinalVolume\\T_{f}=FinalTemperature

Have a nice day!

CH3CH2OH + 302 → 2C02 + 3H2O
Colt1911 [192]

Answer:

Oxygen Gas

Explanation:

The balanced equation shows us the reactant ratio of the reaction.

This means that for every one mole of CH3CH2OH, we need 3 moles of O2 to react with it. Because we need more O2, (3x as much) than ethanol and we have the same given amount (1 mole of each), the oxygen will be the limiting reagent. (1 mole of oxygen would only require 1/3 moles of ethanol to react).

Hope this helped!

How many moles of cesium (Cs) atoms are in 675g Cs?
sweet-ann [11.9K]
The atomic mass of Cs is 132.9. So the mole number of 675 g cesium is 675/132.9 = 5.08 mole. Then the answer should be 5.08 mole.

How long will it take a plane to go 800 miles if it’s traveling at an average speed of 650 miles per hour?
Naya [18.7K]

If there is NO wind resistance, just plain math, this is the answer.

To get the answer you would divide 800 by 650.

800/650 = 1.230769231 (exactly)

That would translate to exactly <span>1 hour 13 minutes and 50 seconds </span>
