the oxidation state of each atom
I think the answer is yellow. Sorry if I got it wrong
<u>Answer: </u>
of volume needs to be pipetted out in the test tube.
<u>Explanation:</u>
We are given:
Mass of BSA to be formed = 
(Conversion factor: 
Volume of stock solution = 
(Conversion factor: 
It is also given that for the mass of BSA is 0.5 g, the volume used up is 1 mL
In order to have, 0.005 g, the volume of stock solution needed will be = 
Hence, of volume needs to be pipetted out in the test tube.
Answer:
1:2:1:2
Explanation:
A molecule is made up of aggregates of small particles called atoms.
CH₄ + 2O₂ → CO₂ + 2H₂O
From the reaction above we have: 1 molecule of methane CH₄ reacting with 2 molecules of oxygen gas O₂ to produce 1 molecule of carbon dioxide gas CO₂ and 2 molecules of H₂O:
CH₄ + 2O₂ → CO₂ + 2H₂O
1 : 2 : 1 : 2
