At the right angle. Both molecules have to be going fast enough and at the right angle or else they will just bounce off
Answer:
yeh they are all correct .
Thus, one atom of carbon will combine with two atoms of oxygen to form the molecule CO 2 ( carbon dioxide ). (b) From the chemical formula of the compound aluminium oxide Al 2 O 3 , the valency of aluminium can be determined. ... Hence the valency of aluminium is 3
<u>Answer:</u> D represents 222, E represents 86, F represents 234 and G represents 90.
<u>Explanation:</u>
The two given chemical reactions are a type of alpha decay processes. Alpha decay process is defined as the process, in which a heavier nuclei decays into lighter nuclei emitting alpha particle. The alpha particle released has a charge of +2 units. and is also known as a helium nucleus.
The isotope formed has atomic mass reduced by 4 units and atomic number reduced by 2 units.
So, for the chemical equations:
1.
D represents 222, E represents 86.
2.
F represents 234 and G represents 90.
Explanation:
Chloroform and silver powder react with each other and exchange the ions with each other to form acetylene molecules which are also called ethyne and silver chloride. The molecule C2H2is called acetylene which is a colourless gas with no odour.
