Answer:
The elements in Group 2 (beryllium, magnesium, calcium, strontium, barium, and radium) are called the alkaline earth metals (see Figure below). These elements have two valence electrons, both of which reside in the outermost s sublevel. The general electron configuration of all alkaline earth metals is ns
C - In DNA, each base pairs up with only
one other base.
Pretty confident on this answers :D
40g(1mol NH3/17.04g per mol), N2's molar mass=28.02g
3CuO+2NH3=>3Cu+N2+3H2O
(2.3473mol NH3)(1 mol N2/2 mol NH3)(28.02g/1mol)=32.8873g N2
15.5/32.8873=47.1306% yield
Answer:
The answer to your question is No
Explanation:
I think it is impossible to go a week without causing any chemical reaction. For example, if a drive my car or motorcycle, I am burning fuel and that is a combustion reaction.
Also, I want to cook, all this process involves a lot of chemical reactions among the components of food and maybe water.
If I take a shower or wash my hands, between the soap and the microbes occur are some chemical reactions that help to remove these organisms.
Also, when I wash my clothes something similar happens.
These are some examples of the chemical reactions that happen daily but I think there are a lot more.
