Answer:
Gas is sometimes measured in cubic feet at a temperature of 60 degrees Fahrenheit and an atmospheric pressure of 14.7 pounds per square inch. Gas production from wells is discussed in terms of thousands or millions of cubic feet (Mcf and MMcf). Resources and reserves are calculated in trillions of cubic feet (Tcf).
Answer:
A. It is possible not all of the water was evaporated from the sand, causing the recovered mass to be higher
D. While drying the NaCl, the liquid boiled and some splattered out of the evaporating dish, causing the recovered mass to be higher.
Explanation:
Sand absorbs water and stores it. The sunlight causes the water to evaporate but sand can hold some of the water inside it. This results in increase in mass of the sand. The mass of sand before and after the water evaporation can be different.
Hello.
He have that:
[H+][OH-] = 10⁻¹⁴
3.64 x 10⁻⁸ [OH-] = 10⁻¹⁴
[OH-] = 0.27 x 10⁻⁶ mol/L
Answer:
24.9 g H2SO4
Explanation:
1.53 x 10^23 / 6.02x10^23 * 98.079g = 24.9 g
There are 600 hours.
explanation
each day has 24 hours and we want to know how much hours is equivalent to 25 days so we multiply 24 times 25 which is 600.
