Molar mass
C₂H₄O₂ = 60.0 g/mol
n = mass / molar mass
3.00 = mass / 60.0
m = 3.00 * 60.0
m = 180 g of <span>C₂H₄O₂

1)Delta H=(Delta H of reactants)-(Delta H of products)
2)And we know CO have 3 bond CO and CO2 have 2 bond that each of them are 2 bond, please see the picture!
so lets answer it:
The direction of heat flow is increased which means blocks temperature is higher and hotter than it was before
It doesn't?
Heat transfers from hot objects to cold objects and for ice to melt it has to increase the temperature.
