Average speed in km/h:
S = D/T
T = 10/60 hrs
= 0.1667
S = 10 / 0.1667
= 59.988 km/h
Answer:
a) V = 1.542 E11 ft³
b) V = 4367011968 m³
c) V = 1.1535 E12 us gal
Explanation:
Acre surface is defined as 66 by 660 feet at a depth of one foot:
⇒ Vacre-foot = 66ft*660ft*1ft = 43560 ft³
lake:
a) V = 3.54 E6 acre-feet * ( 43560 ft³ / acre-foot ) = 1.542 E11 ft³
b) V = 1.542 E11 ft³ * ( 0.02832m³ / ft³ ) = 4367011968 m³
c) V = 1.542 E11 ft³ * ( 7.48052 us gal/ft³ ) = 1.1535 E12 us gal
<u>Answer:</u> The osmotic pressure is 54307.94 Torr.
<u>Explanation:</u>
To calculate the concentration of solute, we use the equation for osmotic pressure, which is:
where,
= osmotic pressure of the solution = ?
i = Van't hoff factor = 3
C = concentration of solute = 0.958 M
R = Gas constant =
T = temperature of the solution =
Putting values in above equation, we get:
Hence, the osmotic pressure is 54307.94 Torr.
Answer is: <span>chemical change occurred.
Electrolysis reaction: 2H</span>₂O → O₂ + 2H₂.
In thic electrolysis reaction two gases are formed, one is oxygen with boiling point of -183°C and second one is hydrogen with boiling point of -253°C. This is chemical change because from one molecule two molecules are produced and because they have new boiling points, boiling point of water is 100°C.
