Answer:
The correct option is the third option
Explanation:
Firstly, it must be noted that chemicals/reagents that are sensitive to sunlight are stored in dark/amber container in the laboratory. Hence, the chloroform can only be found in an amber/dark bottle.
Also, reagents/chemicals that release poisonous/offensive gases are handled in the fume cupboard in the laboratory. Thus, If Malik is going to pour the chloroform, he should pour it in a fume cupboard to avoid inhaling it because of the toxicity of it's vapor.
From the above explanation, it can be deduced that <u>Malik should locate the chloroform stored in a dark container in chemical storage and should take it to the fume hood to pour</u>.
Answer:
the answer is d
Explanation:
from F=Q1Q2
r².
then wen both charges are doubled
F=2Q1 ×2Q2
r²
F=4Q1Q2
r²
then 4 has to be the factor multiplied by the other part of the equation for it to balance
4F=4Q1Q2
r²
so theoretically the 4 on the LHS can cancel the 4 on the RHS
Momentum = Mass × Velocity
From the given data, Mass is 1000kg and Velocity is 20m/s
Momentum = 1000 × 20
