10. nitrous oxide (n2o) can be obtained by the thermal decomposition of ammonium nitrate (nh4no3). (a) write a balanced equation for the reaction. (b) in a certain experiment, a student obtains 0.340 l of the gas at 718 mmhg and 24°c. if the gas weighs 0.580 g, calculate the value of the gas constant.

a) Balanced equation NH4NO3 > N2O + 2H2O b) from equation above; 1 mol of NH4NO3 > 1 mol of N2O thus, 0.46 mol of NH4NO3 > 0.46 mol of N2O mass of N2O = 0.46 x 44 molar mass of N2O = 20.24 gram of N2O AJ · 1 decade ago

Explanation:

Beriberi is a vitamin deficiency disease caused by a deficiency in *THIAMINE* as this isa *THIAMINE*

precursor to the coenzyme which is used in the *PYRUVATE*reactions of the citrate cycle. Brown rice, in which the bran of the rice remains, is considered more nutritious than white rice, in part because this vitamin is not removed. Beriberi can also be caused by consuming foods that contain high levels of *THIAMINASE*, such as uncooked fish and silkworms.

Beriberi is a disease which is also called thiamine deficiency is caused as a result of deficiency in by a vitamin B-1. Beriberi disease can occur in two ways, as wet beriberi or dry beriberi.

Dry beriberi usually attack the nerves and later damage it and which lead to weakening of muscle and eventually paralysis of muscle.

On the other hand, Wet beriberi attack the heart as well as the circulatory system, which can result to heart failure in extreme condition.
