Answer:
single replacement reaction
Explanation:
This is a kind of single replacement reaction where you switch either cations or anions. Here you switched Ca for H and produced Cacl2 and H2 gas by itself.
Answer:
127.28 mmHg
Explanation:
The molar fraction of oxygen in dry air at 760 mmHg is 20.9%. This molar fraction is not affected too much by the height, so it may be taken as a constant. The partial pressure of oxygen may be calculated as:
So, if the total pressure is 609 mmHg,
mmHg.
Answer:
5 valence electron
Explanation:
It is because the group number is equal to the valence electron.
The Seafood Watch is among one of the world's in the industry because of its efficient programs in order to administer the different effects of human intervention in various marine and freshwater ecosystems. In addition to that, these programs promotes speciation in its fishing practices.
Answer:
Explanation:
The stoichiometry for this reaction is
The rate for this reaction can be written as
![-r_{NO_2}=-\frac{d\left[NO_2\right]}{dt}=\frac{(0.01-0.008)M}{100s}=2\times{10}^{-5}\frac{M}{s}](https://tex.z-dn.net/?f=-r_%7BNO_2%7D%3D-%5Cfrac%7Bd%5Cleft%5BNO_2%5Cright%5D%7D%7Bdt%7D%3D%5Cfrac%7B%280.01-0.008%29M%7D%7B100s%7D%3D2%5Ctimes%7B10%7D%5E%7B-5%7D%5Cfrac%7BM%7D%7Bs%7D)
This rate of disappearence of 
can be realated to the rate of appearence of 
as follows (the coefficients of each compound are defined by the stoichiometry of the reaction)
