Nitrous oxide (N2O) is used as an anesthetic (laughing gas) and in aerosol cans to produce whipped cream. It is also a potent gr

eenhouse gas. The decomposition of N2O is first order. It decomposes slowly to N2 and O2:
2 N2O(g) --> 2 N2(g) + O2(g)

Answer:

five half lives

Explanation:

Half-life is the time required for a quantity to reduce to half of its initial value.

How many half lives it would take to reach 3.13% form 100% of it's initial concentration:

100% - 50% : First Half life

50% - 25%: Second Half life

25% - 12.5%: Third Half life

12.5% - 6.25%: Fourth Half life

6.25% - 3.125%: Fifth Half life

This means it would take five half lives to get to 3.125% (≈ 3.13%) of it's original concentration.

Answer:

rising pressure and decreasing temperature

Explanation:

Reversible reactions have a bit practical interest, but in some cases the technological benefit or profitability of production requires a shift in the equilibrium of a reversible reaction.

Increasing pressure

With increasing pressure on this system, the concentration of substances increases. In this case, the balance will shift towards smaller volumes. On the left side of the equation, two volumes of nitrogen react with one volume of hydrogen. On the right side of the equation there are two volumes of ammonia, i.e. the number of volumes on the right side of the equilibrium reaction is less than on the left and, therefore, with increasing pressure, the reaction equilibrium will shift to the right.

Decreasing temperature

When the temperature rises, the equilibrium shifts towards the endothermic reaction, and when the temperature decreases, towards the exothermic reaction and the reaction given above is the exothermic.

A solid object has a mass of 104 kg and a volume of 1,278 m3. what is its density?
Sergio [31]
m=104kg\\
V=1,278m^{3}\\\\
d=\frac{m}{V}=\frac{104kg}{1,278m^{3}}\approx81,38\frac{kg}{m^{3}}

Is it true or false?
svet-max [94.6K]
False. It can’t because a glaciers weight combined with its gradual movement can drastically reshape the landscape over hundreds and even thousands of years.
