Explanation:
I really hope this helps have an amazing day, dont forget YOU ARE WORTH IT
Ok well whats the questions
Answer:
It helps microorganisms grow
Explanation:
I think this is the correct answer because I tried searching it up and you sterilise the petri dish before adding the agar, I've used agar in petri dishes a year ago and im pretty sure they don't make cells glow or make bacteria appear larger.
if I had to have a second guess I'd go with the first one but considering the fact that bacteria is usually to small to see with the naked eye the last option seems correct
To determine the volume of chlorine gas that is needed, we need to first know the reaction. It is expressed as follows:
2Na + Cl2 = 2NaCl
Then, from the amount of NaCl to be produced, we calculate the moles of Cl2 needed.
14.2 g NaCl ( 1 mol / 58.44 g ) ( 1 mol Cl2 / 2 NaCl ) = 0.1215 mol Cl2
To determine the volume of the gas, we need an equation that would relate the number of moles to volume. There are a number of equation available but some are complex equations so we assume that it is an ideal gas. We use the equation:
PV = nRT
V = nRT / P
V = 0.1215 mol ( 0.08205 L-atm / mol-K ) (45.3 +273.15 K) / 1.72 atm
V = 1.85 L Cl2 gas
