the element in each balloon?

Answer:

Oxygen

Explanation:

If two balloons are filled with hydrogen gas and helium gas respectively, then we want to identify what gas is in each balloon, we have to do so by exposing the both balloons to flame in an oxygen atmosphere.

Hydrogen combines with oxygen in the presence of a flame with quite a loud sound and the flame is sustained but when a flame is brought near helium gas in a balloon, the gas will only make a little sound when exposed to the flame and extinguish the flame.

The reason for the explosion of the gas in the hydrogen balloon is that combustion of hydrogen gas is exothermic. The heating up of surrounding air molecules leads to a sudden explosion.

However, the helium balloon makes a little sound when the balloon is ruptured releasing helium gas which extinguishes the flame.

What is the molarity of a 5.00x10^2 mL solution containing 21.1 g of potassium bromide (KBr)? The molar mass of KBr is 119.0 g/m
Dominik [7]
Volume of solution in liters:

5.00 x 10² mL / 1000 => 0.5 L 

number of moles:

mass of solute / molar mass

21.1 / 119.0 => 0.1773 moles

Molarity = number of moles / volume 

M = 0.1773 / 0.5

M = 0.355 mol/L

Answer C

<span>Abiotic factors are non-living things of an ecosystem. Abiotic factors include landscape, climate, pH, salinity and other physical features of the ecosystem. On the other hand, there are b</span>iotic factors. Biotic factors are living things in the ecosystem. Those are plants, animals, and other organisms. Since Algae are living-things, they are biotic factors unlike pH, salinity, and climate which are abiotic factors.
