The answers that are correct are a, b, and d
Explanation:
The dipoles in CO are in opposite directions so they cancel each other out, although CO₂ has polar bonds, it is a nonpolar molecule. Therefore, the only intermolecular forces are London dispersion forces. Water (H2O) has hydrogen bond present which is a polar bond which has a high intermolecular force.
Water which has high intermolecular force will require more energy that is a higher temperature to overcome these attractions and are pulled together tightly to form a solid at higher temperatures, so their freezing point is higher.
As the temperature of a liquid decreases, the average kinetic energy of the molecules decreases and they move more slowly.
CO with lower intermolecular forces will not solidify until the temperature is lowered further.
Answer:
double replacement occurs
Answer:
false
Explanation:
first of all;-energy lead to an indotermic reaction.
indotermic is a reaction that absorbs energy \
*it has positive enthalpy of reaction
*Heat content of product is greater than that of reactant
*Heat is added to reactant side
example;- CO^2+2H^2+891kj --------- CH4 +2O2
