Answer: by finding the main solution
Explanation:
Answer:
All the given elements belong to the second period of the periodic table
Explanation:
Let's locate the elements with the given atomic numbers:
- Z = 3, this corresponds to lithium (Li);
- Z = 4, this corresponds to beryllium (Be);
- Z = 5, this corresponds to boron (B);
- Z = 6, this corresponds to carbon (C);
- Z = 7, this corresponds to nitrogen (N);
- Z = 8, this corresponds to oxygen, (O);
- Z = 9, this corresponds to fluorine, (F).
Now notice that each of these 9 elements can be found in the same row of the periodic table. This is period 2. We may then summarize that all of these elements belong to the same period, period number 2.
Answer:
1: 200 g
2: 100 g per liter
3: unsaturated
4: 300
It might be kind of late, but I just completed that assignment and thought I'd help :)
Answer:
A. The equilibrium constant is very large
Explanation:
The equilibrium constant value is the ratio of the concentrations of the products over the reactants. When a chemical reaction goes to completion, that means that all the reactant has turned into products. As the equilibrium constant defines, it is the ratio of the product to the reactant. So at the final stage of the chemical reaction, the equilibrium constant will be very large.
Answer:
So CO2 = 4 + 6(2) = 16. So, total valence electrons are 16. Carbon is the least electronegative that means it stays at the center. So, put the Carbon in the middle and then set the oxygen either side of that!
