Xenon forms several compounds with oxygen and fluorine. It is the most reactive non-radioactive noble gas because a. its large r
muminat

Answer:

d. its effective nuclear charge is lower than the other noble gases.

Explanation:

Xenon belongs to group O on the periodic table. Most of the elements here are unreactive.

Due to the large size of Xenon, the outermost electrons have very low effective nuclear charge. Effective nuclear charge is the effect of the positive charges of the nucleus on the electrons in orbits. This effect decreases outward as atomic shell increases.

Xenon has a very large atomic radius and there is weak a nuclear charge on the outermost electrons. The more electronegative elements would be able to attract some of its outermost electrons easily and form chemical bonds with xenon much more readily.

Base your answer on the information below and your knowledge of chemistry. Methanol can be manufactured by a reaction that is re
Rudiy27

Explanation:

For the given reaction:

Rate law says that rate of a reaction is directly proportional to the concentration of the reactants each raised to a stoichiometric coefficient determined experimentally called as order.

CO(g)+2H_2(g)\rightarrow CH_3OH(g)

Rate=k[CO]^x[H_2]^y

where x and y are order wrt to CO and H_2

According to collision theory , the molecules must collide for a reaction to take place. According to collision theory , the rate of a reaction is proportional to rate of collision of reactants.

Thus with an increase in concentration of reactants , the rate of reaction also increases. This is because if the concentration of reactants increases , the chances of collision between molecules also increases and thus more products wil be formed which in turn increases the rate of reaction.

How many Grams would he present if 1 mole sample of sodium were collected?
Zigmanuir [339]
Mass = moles x Mr
So in this case the moles =1
And the Mr equals =11
So you would do - 11x1= 11grams
