Answer:
A. 0.064mol
B. 0.85mol
C. 1500mL
Explanation:
A. Molarity = 0.33M
Volume = 195mL = 195/1000 = 0.195L
Mole =?
Molarity = mole /Volume
Mole = Molarity x Volume
Mole = 0.33 x 0.195
Mole = 0.064mol
B. Molarity = 1.7M
Volume = 500mL = 500/1000 = 0.5L
Mole =?
Molarity = mole /Volume
Mole = Molarity x Volume
Mole = 1.7 x 0.5
Mole = 0.85mol
C. C1 = 12M
V1 = 50mL
C2 = 0.4M
V2 =?
Using the dilution formula C1V1 = C2V2, we find the volume of the diluted solution as follows:
C1V1 = C2V2
12 x 50 = 0.4 x V2
Divide both side by 0.4
V2 = (12 x 50) /0.4
V2 = 1500mL
Where do the hydrogen and oxygen atoms come from that become part of the glucose molecule made during photosynthesis? The oxygen molecules come from carbon dioxide and water. The hydrogen atoms come from water.
Hope this helps.
Answer:Ethanol can be made by a process called fermentation. During fermentation, sugar (glucose) from plant material is converted into ethanol and carbon dioxide. ... 90 per cent of the world's ethanol is made using fermentation.
Explanation:
By increasing the amount of energy produced by friction of the cloth can generate a electrical charge.
