Well, when an atom attains a stable valence electron, it means that the outer electrons are complete and so cannot attain any more electrons. For the first shell, it is complete when it has 2 electrons, the second shell is complete when it has 8 electrons, all the other shells also have a particular number when complete. Anyway, i believe the answer is HYDROGEN because when HYDROGEN combines with another atom of HYDROGEN, the outer shell is completed. This is because HYDROGEN has only 1 electron. If the two HYDROGENS, which both have 1 electron combine, they make the electrons 2, which is complete for the first shell, HYDROGEN ends in the first shell. Since the electrons become 2, the shell is at stable valence. In all the other options, this happens;
NEON- It has 10 electrons, 2 in the first shell and 8 in the second. So the the shells are already complete, so it can't bond with any thing, which is completely against the question.
RADON- Radon has 86 electrons.
HELIUM- Helium has 2 electrons, so the shell is already full, and cannot bond, so it goes against the question. The question says BY BONDING.
So the answer is definitely 4) HYDROGEN
Hope i helped. Have a nice day, by the way, i'm very sure it's hydrogen.
First convert the kg to g ----- 0.03kg = 30g
Then divide the mass by the volume ----- 30g ÷ 25mL = 1.2
The density is 1.2g/mL<span />
Answer:
on the right side, because it is a product
Explanation:
photosynthesis is the chemical reaction with the help of which plants produce chemical energy with the help of light energy.
_______________________________________________
The general standard for writing chemical reaction is that
- The chemical which are input to the process of chemical reaction are written on left hand side . They are known as reactant.
- The output of chemical reaction are written on right side. They are termed as product.
- Transition of reactant to product is shown by arrow.
Chemical reaction for photosynthesis is given by below equation
6CO2 + 12H2O + light ----------------> C6H12O6 + 6O2 + 6H2O
We can see that 6 molecules of light combines with 12 molecules of water to give one molecule of glucose and 6 molecules of both water and oxygen.
As, oxygen is the output of photosynthesis process, it is written on the right-hand side of equation and is product of this reaction.
.
Thus, of the options given below for
In an equation for photosynthesis does oxygen belong
on the right side, because it is a product
Explanation:
three things that you would notice a chemical reaction is the change of color and change in odor and the change in temperature
