2mm=2,000,000 nm
2,000,000/25=80,000
The answer is 80,000 polio viruses
Answer:
your answer to your question is B
Solid liquid and gas is the answer
Answer:
option C = Reactant: 4NH₃ + 6NO → product: 5N₂ + 6H₂O
Explanation:
Chemical equation:
NH₃ + NO → N₂ + H₂O
Balanced chemical equation:
4NH₃ + 6NO → 5N₂ + 6H₂O
Ammonia is react with nitrogen mono oxide and produced nitrogen and water.
Ammonia and nitrogen monoxide are reactants while water and nitrogen are product.
Four number of moles of ammonia react with six nitrogen monoxide and produced five mole of nitrogen and six mole of water.
Explanation:
According to the law of dilution,
The given data is as follows.
= 0.4782, 
= ?
= 0.025
, 
= 250 mL
Hence, we will calculate the value of as follows.
= 
= 13.07
Thus, we can conclude that we need 13.07 mL 0.4782 M sodium thiosulfate solution using pipette.
