Answer:
Earth's gravitational pull making it stay in orbit
Explanation:
Answer:
D. 1.0 x 10-8.43
Explanation:
The pH is an unit of concentration in chemistry used to determine the acidity -or basicity- of a particular solution. Is used in quality control to determine the security of a product for consumers.
The equation is:
pH = -log [H₃O⁺]
As pH = 8.43:
8.43 = -log [H₃O⁺]
10^-8.43 = [H₃O⁺]
1.0x10 -8.43 = [H₃O⁺]
Right option is:
<h3>D. 1.0 x 10-8.43
</h3>
Decreasing the concentration would decrease the reaction rate (option c)
The aforementioned statement is due to the fact that when a substance's concentration is high, it will quickly perform the chemical reaction as there are more particles reacting with one another. Conversely, if there is less of a concentration, then the reaction rate would decrease as there are little particles reacting with one another.
This says four figures. The 4 figures you should use are 4546 with a peek at 7 to see what effect it will have on the 4 main figures.
45.467 rounds to 45.47
You round the 4th figure up one. You are not concerned about the decimal places in this question.
M1V1 = M2V2
M1 = 3.000 M
V1 = 0.8000 L
M2 = ?
V2 = 2.00 L
M2 = M1V1/V2 = (3.000 M)(0.8000 L)/(2.00 L) = 1.20 M
