The ballon would expand since it is endothermic it absorbs the heat the opposite would happen in the cold simile to how doors swell in there frames in warm weather....in other words it gets bigger
Answer:
0.016 moles of product will obtain.
Explanation:
Given data:
Moles of K = 0.032 mol
Moles of product = ?
Solution:
Chemical equation:
4K + O₂ → 2K₂O
Now we will compare the moles of K with K₂O.
K : K₂O
4 : 2
0.032 : 2/4 ×0.032 = 0.016 mol
0.016 moles of product will obtain.
Answer:
a. 916.95K is final temperature of the gas
b. 3667.8K
Explanation:
a. We can solve the temperature of a gas when the volume is expanded three times using Gay-Lussac's law:
P₁T₂ = P₂T₁
<em>Where P is pressure,</em>
<em>And T is absolute temperature of 1, initial states and 2, final states of the gas.</em>
<em />
Initial pressure is 6.60 atm, initial absolute temperature is 32.5°C + 273.15K = 305.65K. Final pressure is three times initial pressure = 6.60atm*3 = 19.8atm.
Solving for final temperature:
P₁T₂ = P₂T₁
6.60atm*T₂ = 19.8atm*305.65K
T₂ =
916.95K is final temperature of the gas
<em />
b. Charle's law is the gas law that relates changes in volume and temperature of a gas:
V₁T₂ = V₂*T₁
If the volume is quadrupled: V₂/V₁ = 4:
T₂ = 4*916.95K
T₂ = 3667.8K
Explanation:
When there is transfer of electrons between two atoms then it results in the formation of an ionic bond.
Whereas when there is sharing of electrons between two atoms then it results in the formation of covalent bond.
, , and are ionic compounds as there is bond formation between a metal and a non-metal. So, there will be transfer of electrons and as a result, ionic bond is formed.
is a compound which contains non-metals C and S. Therefore, bond formation is due to sharing of electrons thus, there is covalent bond.
has symmetrical structure and will have equal sharing of electrons. Hence, the molecule will have non-polar covalent bond.
