Answer:
c and o
Explanation:
Carbon and Oxygen cannot react to form an ionic compound because the two elements are non-metals.
- To form an ionic bond, a metal combines with a non-metal through electrostatic attraction of oppositely charged ions.
- This leads the bond formation.
- Carbon is a non-metal, with oxygen, they will prefer to form a covalent bond where they share their electrons
Answer:
Something defined as hydrophilic is actually attracted to water, while something that is hydrophobic resists water.

Answer:
4.35 * 10^-8 M
Explanation:
Since the concentration of the hydronium ion= 2.3 X 10^-7 M
And we know that;
[H3O^+] [OH^-] = 1 * 10^-14
[H3O^+] = concentration of the hydronium ion
[OH^-] = concentration of the hydroxide ion
So;
[OH^-] =1 * 10^-14/[ H3O^+]
But [H3O^+] = 2.3 X 10^-7 M
[OH^-] = 1 * 10^-14/2.3 X 10^-7
[OH^-] = 4.35 * 10^-8 M
Answer:
A) 3.6 cm
Explanation:
Accuracy comes down to how precisely you can read the length on a given scale. Here since the smallest increment is centimeter, we can go only one decimal beyond to estimate. This is because you can usually estimate to only one decimal place beyond the closest marks on any measuring.
So, the answer should be 3.6 cm.
Here's a document that explains it well: https://www.auburn.wednet.edu/cms/lib03/WA01001938/Centricity/Domain/1360/1_Uncertainty.pdf
Hope that's right!
