Answer:
Assuming no calorie intake from water or minerals, if a 100 gram steak contains 49% water, 15% protein, 0% carbohydrates, and 36% fat, what is the estimated gross energy content of the steak (in kcal)?
To name compounds, usually, they are a combination of a metal and a nonmetal, between nonmetals and between metals. The two elements here are ammonium (NH₄) and sulfur (S). These are both nonmetals. When you name the compound, start by ammonium, followed by sulfur plus a suffix of -ide. The compound is ammonium sulfide.
Answer:
<u>We are given:</u>
v1 = 3.2 L v2 = x L
p1 = 822 torr OR 1.08 atm p2 = 2.33 atm
t1 = t2 = 284 k
<u></u>
<u>From the Ideal gas equation:</u>
PV = nRT
Since the number of moles (n), universal gas constant (R) and Temperature (T) are constant
PV = k (where k is a constant)
it can also be written as:
P1V1 = k --------------------------(1)
Similarly,
P2V2 = k (where k is the same constant as before)----------(2)
<u>Solving for V2:</u>
From (1) and (2):
P1V1 = P2V2
Replacing the variables
1.08 * 3.2 = 2.33 * x
x = (1.08 * 3.2)/2.33
x = 1.5 L (approx)
Therefore, the final volume of the solution will be 1.5L
