Actual yield/Theoretical yield *100= Percentage yield. So Actual yield = Percentage yield*Theoretical yield.
Therefore actual yield= 90/100 * 1.09g = 0.98g
Actual yield: 0.98 g
Answer:
176984.38J
Explanation:
E = mC∆T
Where E is the energy in joules
M is the mass of water
C is the specific heat capacity of water =4.184J/g°C
It is known that it will take 4.184J of energy to change the temperature of water by one degree Celsius.
∆T = 98.6°c - 5.4°c
= 93.2°c
∆H = 454.3g × 4.18J/g°C × 93.2°c
= 176984.3768
176984.38J
Due to it's electronic configuration w/c is 1s2 2s2 2ps 3s1 considering the last w/c is 3s1, sodium should be in row 3 period a1.
1. Heart
2. Circulatory system
3. The circulatory system delivers oxygen and nutrients to cells and take away water .
4. Your heart is a muscle and it’s job is to pump blood throughout your circulatory system.
Hope this helps :)
Have a great day!
