Answer:

The balloon will continue to expand and eventually burst.

Explanation:

Simply, the reason for this is because the density of the atmosphere decreases gradually as you increase in altitude closer to space. This means that the air on the outside of the balloon can't provide enough pressure over the surface of the balloon in order to counteract the gas on the inside of the balloon from expanding.

How many moles of N2O5 are needed to produce 7.90 g of NO2 <br><br> 2N2O5 = 4NO2 + O2

Furkat [3]

From the chemical eqn
No of moles of N2O5 = Mass/ molar mass
Molar mass = (14* 2) + (16 *5) = 28 + 90 = 118g.
From the chemical equation 7.9g of NO2 reacts with 7.9 *2 g of N2O5. We have a 1 :2 mole ratio. Hence mass of N2O5 = 14.8g
No of moles = 14.8/ 118 = 0.133 moles.

Under metric prefixes, if a meter were divided into 100 equal-sized subunits, a single unit would be called a

joja [24]

Answer:

In metric prefixes, if a meter were divided into 100 equal-sized subunits, a single unit would be called a centimeter.

Explanation:

Here we asked to divide 1 meter in to 100 equal parts.

Let us find out what is the length of piece when 1 m is divided in to 100 equal parts.

Length

$l = \frac{1}{100} = 0.01m$

That is length of 1 m divided into 100 equal parts is 0.01m.

We know that 0.01 m is 1 centimeter.

So, in metric prefixes, if a meter were divided into 100 equal-sized subunits, a single unit would be called a centimeter.
