Answer:
The answer is sodium chloride
Explanation:
since Na is more reactive than Ag it displaces the Ag from AgCl
check the reactivity series to prove the point
SI unit- Quantity
second- time
kilogram- mass
kelvin- temperature
ampere- electric current
S.I. Unit of time is second.
S.I. Unit of mass is kilogram.
S.I. Unit of temperature is kelvin.
S.I. Unit of electric current is ampere.
So match will be as follows:
second- time
kilogram- mass
kelvin- temperature
ampere- electric current
Answer : The temperature on the Fahrenheit scale was, 
Explanation :
The conversion used for the temperature from degree centigrade to Fahrenheit is:

where,
= temperature in Fahrenheit
= temperature in centigrade
As we are given the temperature in degree centigrade is, 45
Now we have to determine the temperature in Fahrenheit.


Therefore, the temperature on the Fahrenheit scale was, 
Answer:process of using an electrical current to separate water into hydrogen and oxygen gas
Explanation:
The balanced equation would be (1)BaCl2 + (1)H2SO4 --> (1)BaSO4 + (2)HCl2
Then you should know that the coefficients stand for moles.
The thing is I'm not sure if H2SO4 is 35 ml or .200 m.
Also, is this topic stoichiometry?
