Ba²⁺(aq) + CO₃²⁻(aq) → BaCO₃(s)
Answer:
Independent variable is what you change in a experiment
No because they have their full octet. They are full and don't need to bond with any other atoms. The full atoms that are happy are the noble gases.
---- If you need anymore chemistry help ask me....because im very good at chemistry.
Q must be supplied = 119523.3~J
<h3>Further explanation </h3>
The law of conservation of energy can be applied to heat changes, i.e. the heat received/absorbed is the same as the heat released
Q in = Q out
Heat can be calculated using the formula:
Q = mc∆T
Q = heat, J
m = mass, g
c = specific heat, joules / g ° C
∆T = temperature difference, ° C / K
So from the question :
Q to the system(Q supplied) = Q water + Q steel vessel(Q gained)
