Answer:1962kJ
Explanation:
m=2000 kg
h=100m
G=9.81m/s²
GPE=m*G*h
GPE=2000kg*100m*9.81m/s²=1,962,000J=1962 kJ
Answer:
8 moles of CO
Explanation:
To produce carbon monoxide we begin from C and O₂ as this reaction shows:
2C + O₂ → 2CO
Therefore, 2 moles of C can produce 2 moles of CO
If I have 8 moles of C, I must produce 8 moles of CO
Ratio is 1:1
First, 1 foot = 30.48cm (12 inches x 2.54 cm/inch=30.48 cm). So, 8,5 ft = 8.5 x 30.48cc=259.08 cm, 7.5 ft = 7.5 x 30.48=228.6cm and 9.5/12=0.791ft x 30.48 =24.11cm. So, in cc, 259.08 x 228.6 x 24.11 = 1,427,931.3 cc. Since 1 cc of water = 1 gram then we have 1,427,931`grams or 1427. 931 kg x 2.2 lbs/kg = 3141 pounds of water or 1.57 tonnes of water so with this size of waterbed if upstairs the house structure must be able to withstand this stress.
I believe its 10^23 u r saying
then no. of moles= 9.03*10^23/6.02*10^23=1.5mole
Answer:
1.44 L
Explanation:
If the temp does not change
P1V1 = P2V2
1 * 3.6 = 2.5 * V2
V2 = 1.44 L
