The correct answer is False

Explanation:

A microscope is an instrument used in many scientific fields including biology and chemistry to magnify the image of an object and therefore study and look at it, which is not possible without a microscope due to the limitations of the human eye. Additionally, a compound microscope is a type of microscope that includes multiple lenses to magnify objects and therefore, allows scientist to observe the same object with different sizes. About this, it is important to mention the range objects can be magnified depends on the type of microscopes but in general terms, this type of microscope include lenses that magnify objects from 10 times to around 400 times, and especial microscopes can magnify objects up to 1000 times. Thus, it is false a compound microscope can magnify something only up to 200 times.

Choose all of the following mole ratios that are correct for the reaction given below. Be sure to choose all that apply.
Dennis_Churaev [7]

Answer:

2 moles NH3 = 1 mole of N2

3 moles of H2 = 1 mole of N2

3 moles of H2 = 2 moles of NH3

Explanation:

The balanced equation for the reaction is given below:

N2 + 3H2 —> 2NH3

From the balanced equation above,

1 mole of N2 reacted with 3 moles of H2 to produce 2 moles of NH3.

Thus, we can say that:

1 mole of N2 = 3 moles of H2

1 mole of N2 = 2 moles of NH3

3 moles of H2 = 2 moles of NH3

Thus, considering the options given above, the right answers to the question are:

2 moles NH3 = 1 mole of N2

3 moles of H2 = 1 mole of N2

3 moles of H2 = 2 moles of NH3

What is the volume of a weather balloon that has 39 grams of helium with a density 0.017 g/mL?
olchik [2.2K]

Answer:

<h3>The answer is 235.29 mL</h3>

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

volume =  \frac{mass}{density}  \\

From the question.

density = 0.017 g/mL

mass = 4 g

We have

volume =  \frac{4}{0.017}  \\  = 235.2941176...

We have the final answer as

<h3>235.29 mL</h3>

Hope this helps you
