How many molecules are there in 123.2g of CO2?

If a reaction has g of -136kj at 110°c, will it be spontaneous at this temperature (110°c)? yes or no

The boiling point of propanoic acid is higher than that of 1-butanol because: propanoic acid has a higher molecular weight than 1-butanol. propanoic acid is more soluble in water than 1-butanol. propanoic acid is a better hydrogen bond donor than 1-butanol. propanoic acid forms hydrogen bonded dimers and 1-butanol does not. 1-butanol forms hydrogen bonded dimers and propanoic acid does not.

Why does his teacher ask him to balance the equation by including the correct coefficient
