Answer: hey nice to see you again, the answer is B. Microscopes allowed scientists to see the cells.
Explanation:
Yes they will need to worry cause the chemicals could spread in the water making it explode and kill animals and it would be very bad
Oxidation reaction
In ---> In³⁺ + 3e ---1)
reduction reaction
Cd²⁺ + 2e ---> Cd ---2)
when balancing the reactions, electrons have to be balanced. to balance the electrons multiple 1st reaction by 2 and 2nd reaction by 3
1) x 2
2) x 3
2In ---> 2In³⁺ + 6e
3Cd²⁺ + 6e ---> 3Cd
add the 2 equations to obtain the overall reaction
2In + 3Cd²⁺ ---> 2In³⁺ + 3Cd
Answer: 368 grams of sodium reacted.
Explanation:
The balanced reaction is :
According to stoichiometry :
2 moles of 
are formed from = 2 moles of 
Thus 16 moles of are formed from=
of
Mass of 
Thus 368 grams of sodium reacted.
