3K2CO3 + 2Fe(NO3)3 > 2K3(NO3)3 + Fe2(CO3)3
Most likely the geometric form of the molecule will be linear.
Explanation:
One possibility is the central atom being an atom with two valance electrons. This will create a liner molecule with no lone pairs of electrons
Another possibility is a central atom being an atom with four valance electrons. If the two atoms each require two bonds like oxygen the result will be a linear molecule with no lone pairs of electrons.
B because if more soot comes then the darker they will get.
I’m not sure but I’m sure it’s b please thank me
The formula you need is: heat= specific heat x mass x ΔT
specific heat= 0.46 j/g-C
mass= 100.0 grams
ΔT= 40.2 - 15.0= 25.2C
heat= (0.46) x (100.0) x (25.2)= 1159.2 joules or 1200 joules (rounded off)
