On the reactants side, you'll always have some sort of compound of carbon and hydrogen and oxide, while the products will always be CO2 (carbon dioxide) and H2O (water)
The improvement of the microscope allowed for scientist to clearly see cells better than ever before.
Answer:
0.01M = [H⁺]; 1x10⁻¹²M = [OH⁻]; Ratio is: 1x10¹⁰
Explanation:
pH is defined as -log [H⁺]
For a pH of 2 we can solve [H⁺] as follows:
pH = -log [H⁺]
2 = -log [H⁺]
10^-2 = [H⁺]
<h3>0.01M = [H⁺]</h3>
Using Keq of water:
Keq = 1x10⁻¹⁴ = [H⁺] [OH⁻]
1x10⁻¹⁴ / 0.01M = [OH⁻]
<h3>1x10⁻¹²M = [OH⁻]</h3><h3 />
The ratio is:
[H⁺] / [OH⁻] = 0.01 / 1x10⁻¹² =
<h3>1x10¹⁰</h3>
Answer:
B
Explanation:
A. Is wrong
This definition in this option does not fully define what an open system entails. It only gave a one sided definition of the phenomenon on ground
B is correct
In an open system, matter and energy should be free to leave
C is incorrect
This is clearly a one sided definition like A and should not be taken serious
D is incorrect
D is talking essentially about what a closed system is
4km I believe is the answer
