Answer:

a. 5.77L

b. 700mmHg

c. 395K

Explanation:

Using PV = nRT we can solve these problems where:

P is pressure of the gas in atm (1atm = 760mmHg)

V is volume in liters

n are moles of the gas

R is gas constant: 0.082atmL/molK

T is asbolute temperature in K

a. PV = nRT

V = nRT/P

P = 773mmHg*(1atm/760mmHg) = 1.017atm

T = 25°C+273 = 298K

V = 0.240mol*0.082atmL/molK*298K / 1.017atm

V = 5.77L

b. PV = nRT

P = nRT/V

P = 0.0947mol*0.082atmL/molK*309K/0.635L

P = 0.9216atm * (760mmHg/1atm) = 700mmHg

c. PV = nRT

PV/nR = T

P = 727mmHg * (1atm / 760mmHg) = 0.9566atm

0.9566atm*13.3L/0.393mol*0.082atmL/molK = T

T = 395K

Which notations represent hydrogen isotopes?
lisabon 2012 [21]

Isotopes are chemical elements with same atomic number (Z), but different mass number (different number of neutrons).

Hydrogen is an element with atomic number 1. It has three isotopes:

1) protium (₁¹H), with mass number 1 (no neutrons).

2) deuterium (₁²H), with mass number 2 (one neutrons, n° = 2 -1, n° = 1).

3) tritium (₁³H), with mass number 3 (two neutrons, n° = 3 -1, n° = 2).

1. Energy in foods is provided by
ELEN [110]

Answer:

Energy in foods is provided by macro-nutrients.

Explanation:

Nutrients are “environmental substances” used for growth, energy, and bodily functions of the  organisms. Those nutrients that are required  in larger amounts are called macro-nutrients.

There are 3 macro-nutrients needed by humans: lipids (fats), carbohydrates (sugar) and proteins. All these macro-nutrients gives energy in  form of “calories”. For example:

  • In carbohydrates, there are '4 calories' of energy per gram.
  • In proteins, there are '4 calories' of energy per gram.
  • And in lipids, there are '9 calories' of energy in one gram.

This means that if you look at a food label and it lists 10 grams of carbohydrates, 0 grams of protein, and 0 grams of fat, that food would contain 40 calories.
