Liquids and solids are left out of the equilibrium constant expression because their concentrations remain constant during react

ions. What is the molarity concentration of liquid water at 25.0 LaTeX: ^\circ ∘C given that its density is 0.997 g/mL at that temperature?
a.23.5 M
b.0.997 M
c.0.180 M
d.0.156 M
e.55.3 M

Answer:

55.3 M

Explanation:

Given temperature = 25°C

Density = 0.997 g/mL

Based on density the mass of water per L = 997 grams

The molar mass of water = 18

The moles of water = \frac{mass}{molarmass}=\frac{997}{18}=55.3

The molarity is defined as the moles of water per litre.

The moles = 55.3

Volume = 1 L

So molarity = 55.3 /1 = 55.3 M

If a pork roast must absorb kJ to fully cook, and if only 10% of the heat produced by the barbecue is actually absorbed by the r
kolezko [41]

Answer:

1,033.56 grams of carbon dioxide was emitted into the atmosphere.

Explanation:

C_3H_8(g)+5O_2(g)\rightarrow 3CO_2(g)+4H_2O(g),\Delta H_{rxn}=-2044 kJ/mol (assuming)

Energy absorbed by pork,E = 1.6\times 10^3 kJ (assuming)

Total energy produced by barbecue = Q

Percentage of energy absorbed by pork = 10%

10\%=\frac{E}{Q}\times 100

Q=\frac{E}{10}\times 100=\frac{1.6\times 10^3 kJ}{10}\times 100=1.6\times 10^4 kJ

Since, it is a energy produced in order to indicate the direction of heat produced we will use negative sign.

Q = -1.6\times 10^4 kJ

Moles of propane burnt to produce Q energy =n

n\times \Delta H_{rxn}=Q

n=\frac{Q}{\Delta H_{rxn}}=\frac{-1.6\times 10^4 kJ}{-2044 kJ/mol}=7.83 mol

According to reaction , 1 mol of propane gives 3 moles of carbon dioxide. then 7.83 moles of will give:

\frac{1}{3}\times 7.83 mol=23.49 mol carbon dioxide gas.

Mass of 23.49 moles of carbon dioxide gas:

23.49 mol × 44 g/mol =1,033.56 g

1,033.56 grams of carbon dioxide was emitted into the atmosphere.

How is energy transferred during convection?
Natalija [7]

The field of energy is wide and interesting due to it can be expressed by differents way.

The thermal energy is associated like internal energy of the atoms or molecules of a substance.  The transfer of thermal energy as heat can take place via convection.

Convection via is the transfer of thermal energy due to the motion of the substance that contains the thermal energy.

4. The picture shows a full moon.
Anuta_ua [19.1K]

Answer:

A full moon occurs when the Moon appears as a complete circle in the sky.

Explanation:

- We see it as a full orb because the whole of the side of the Moon facing the Earth is lit up by the Sun's rays.

- The moon shows no visible light of its own, so we only see the parts of the moon that are lit up by other objects.
