Which of the following shows the conservation of mass during cellular respiration? a. 3 c o2 + 3 h2 o + energy → 3 c6 h12 o6 + 3 o2 b. 6 c o2 + 6 h2 o + energy → c6 h12 o6 + 6 o2 c. c6 h12 o6 + 6 o2 → 6 c o2 + 6 h2 o + energy d. 6 h2 o + c6 h12 o6 → 6 o2 + energy

Unpolarized light falls on two polarizer sheets whose transmission axes are at right angles. a third polarizer is placed between the first two so that its axis makes a 52-degree angle with the axis of the first polarizer. a) what fraction of the incident light intensity is transmitted through the first polaroid? b) what fraction of the incident light intensity is transmitted through the second polaroid? c) what is the angle of polarization of the light that enters the third polaroid? d) what fraction of the incident light intensity is transmitted through the third polaroid. e) what happens if the middle polaroid is removed?

A40.0 l tank of ammonia has a pressure of 12.7 kpa. calculate the. volume of the ammonia if it’s pressure is changed to 8.4 kpa while its temperature remains constant.
