C7H14 + 10.5 O2 -> 7 CO2 + 7 H2O
Or, if whole numbers must be used:
2 C7H14 + 21 O2 -> 14 CO2 + 7 H2O
Sorry idk. i was trying to figure it out but i cant
Answer:
Selling price of watch A and watch B= Rs. 425
Let cost price of watch A=x
Profit =10%
∴
100
110
x=425
x=386.36
Let cost price of watch B=y
Loss =10%
∴
100
90
y=425
y=472.22
Net cost price =x+y=858.5858
Net selling price =850
Loss%=
858.58
858.5858−850
×100=1%

Answer:
3.45 moles Li contains 2.08 × 10 (to the power of)24 atoms .
Explanation:
The relationship between atoms and moles is:
1 mole atoms =
6.022 × 10 (to the power of)23
atoms
In order to determine how many atoms occupy a given number of moles, multiply the given moles by
6.022 × 10 (to the power of)23
atoms/mole
.
In the case of 3.45 moles lithium (Li):
3.45 mol Li × 6.022 × 10 (to the power of)23 atoms Li/ 1 mol Li =
2.08 × 10 (to the power of)24
atoms Li rounded to three
Answer:
The answer to your question is: V = 60.3 ml
Explanation:
Data
V1 = 500 ml
T1 = 27°C = 300°K
P1 = 75 mmHg = 0.098 atm
V2 = ?
T2 = - 33°C = 240°K
P2 = 0.65 atm
Formula
V2 = 60.3 ml
