Which of the following elements has the smallest atomic radius
babunello [35]

Answer:

Element with the smallest radius is Carbon.

Explanation:

In a periodic table, atomic radius increases down the group due to addition of a new shell and decreases across the period from left to right due to increasing nuclear charge.

Due to addition of more electrons in same shell and increase of positive charge in nucleus increases attractive forces between electrons and nucleus hence decreasing size.

Carbon and Lithium are present in same period and hence Carbon has smaller size; Potassium and Bromine are present in same period and hence out of the two, Bromine has smaller size.

On comparing Carbon and Bromine, atomic radius increases down the group hence, Carbon has the smallest radius among the four given elements.

For the following reaction, KP = 0.455 at 945°C: At equilibrium, is 1.78 atm. What is the equilibrium partial pressure of CH4 in
Alborosie

Answer:

See explanation below

Explanation:

The question is incomplete. However, here's the missing part of the question:

<em>"For the following reaction, Kp = 0.455 at 945 °C: </em>

<em>C(s) + 2H2(g) <--> CH4(g). </em>

<em>At equilibrium the partial pressure of H2 is 1.78 atm. What is the equilibrium partial pressure of CH4(g)?"</em>

With these question, and knowing the value of equilibrium of this reaction we can calculate the partial pressure of CH4.

The expression of Kp for this reaction is:

Kp = PpCH4 / (PpH2)²

We know the value of Kp and pressure of hydrogen, so, let's solve for CH4:

PpCH4 = Kp * PpH2²

*: You should note that we don't use Carbon here, because it's solid, and solids and liquids do not contribute in the expression of equilibrium, mainly because their concentration is constant and near to 1.

Now solving for PpCH4:

PpCH4 = 0.455 * (1.78)²

<u><em>PpCH4 = 1.44 atm</em></u>

The energy content of food is typically determined using a bomb calorimeter. Consider the combustion of a 0.22-g sample of butte
iren2701 [21]

Answer: The energy of combustion of butter is 31.5 kJ/g

Explanation:

The quantity of heat required to raise the temperature of a substance by one degree Celsius is called the specific heat capacity.

Q=C\times \Delta T

Q = Heat absorbed by calorimeter =?

C = heat capacity of calorimeter = 2.67kJ/^0C

Initial temperature of the calorimeter  = T_i = 23.5^0C

Final temperature of the calorimeter  = T_f  = 26.1^0C

Change in temperature ,\Delta T=T_f-T_i=(26.1-23.5)^0C=2.6^0C

Putting in the values, we get:

Q=2.67kJ/^0C\times 2.6^0C=6.94kJ

As heat absorbed by calorimeter is equal to heat released by combustion of butter

Q=q

Heat released by 0.22 g of butter = 6.94 kJ

Heat released by 1g of butter = \frac{6.94}{0.22}\times 1=31.5kJ

The energy of combustion of butter is 31.5 kJ/g
