Answer: The pressure in torr is 461 torr
Explanation:
To calculate the relation of density and molar mass of a compound, we use the ideal gas equation:
PV=nRT
P = pressure
V = Volume
n = number of moles
R = gas constant = 0.0821 Latm/Kmol
T = temperature =
Number of moles (n) can be written as:

where, m = given mass
M = molar mass = 44 g/mol

where,

where d = density = 2.54 g/L
The relation becomes:
PM=dRT


(760torr=1atm)
Thus the pressure in torr is 461 torr
Answer: They are are simular because when the wax cools down its not hot or it cools down it is the same with hot water it cools after along while.
Explanation:
All of the energy from the reactants will be lost to the surroundings.The energy found in the reactants remains in the system, and the reactants also take energy from the
surroundings is true of energy in reactants during endothermic reaction.
<h3>What is Endothermic reaction?</h3>
Endothermic reaction is a reaction in thermochemistry where the reactants absorb heat from the surrounding to form the products.
In an endothermic reaction, the products have more energy than the reactants, that is they absorbed more energy. The reactants have less energy,that is they loss energy . Therefore, the change in enthalpy is positive, heat is absorbed from the surroundings during the reaction.
Therefore, All of the energy from the reactants will be lost to the surroundings.
The energy found in the reactants remains in the system, and the reactants also take energy from the
surroundings is true of energy in reactants during endothermic reaction.
