Answer:
3.2M HCl Solution
Explanation:
Molarity = moles of solute / volume of solution expressed in liters
moles of solute = 0.80 moles HCl
volume of solution = 250 ml = 0.250 Liter
Molarity (M) = 0.80 moles HCl / 0.250 Liters = 3.2M HCl Solution
We know power=work done/time taken
power*time= work
100watt=0.1kw
total work in a day= power* time
0.1*5.5=0.55kwh
for 1 year total.energy is 0.55*365=200.75kwh
cost is 200.75*0.13=26.0975dollars
for 25 watt it is 0.025*5.5*365*0.13=6.524375 dollars
Answer:
Three things about our body's systems:
All systems have a method of self-regulation or exogenous regulation by other systems.
All systems have a balance in their functions.
All the systems of our organism are intertwined with each other thus giving general vitality.
Explanation:
Best known systems:
Renal, respiratory, circulatory, cardiac, nervous, immune, blood, muscular systems.
All of them include the participation of one or more organs
The answer to the problem is A because the velocity of the plane changes when she turns it
Answer:
0.653
Explanation:
1)
M1V1 = M2V2
M1 = 5.04 M
V1 = 229 mL ( you take only this volume)
V2 = 921 mL
5.04*229 = M2 * 921
M2 = (5.04*229)/921 Molarity
2)
M1V1 = M2V2
M1 = (5.04*229)/921
V1 = 100 mL
V2= 192 mL
(5.04*229)/921 *100 = M2 * 192
M2 = [(5.04*229)/921 *100]/192 = 0.653 final molarity
