Answer:

Mass to moles: mass/molar mass=mole

Moles to mass: moles x molar mass = mass

Moles to particles:1mole = 6.022x10^23 particles

Particles to moles: 1 particle =1/(6.022x10^23) mole

Zielflug [23.3K]

Answer:

$Cv_{calorimeter}=18.4kcal/K$

Explanation:

Hello!

In this case, since the combustion of the hamburger released 335.4 kcal of energy and that energy is received by the calorimeter, we can write:

$Q_{hamburguer}=-Q_{calorimeter}$

And the heat of the calorimeter is written in terms of the temperature change and the calorimeter constant:

$Q_{hamburguer}=-Cv_{calorimeter}\Delta T$

Thus, given the released heat by the hamburger due to its combustion and the temperature change, Cv for the calorimeter turns out:

$Cv_{calorimeter}=\frac{-Q_{hamburguer}}{\Delta T} =\frac{-(-335.4kcal)}{18.2K}\\\\Cv_{calorimeter}=18.4kcal/K$

Best regards!

How does the chemical formula for water influence its chemical properties?

OLga [1]

The chemical formula is composed of hydrogen and oxygen where the two atoms are bonded through hydrogen bond type of bonding. In this pair, the oxygen is the more electronegative atom hence the electrons are more directed to it. Because of this, this creates electron polarity which affects the chemical property of water.
