B) gets smaller
The concentration of hydrogen atoms is inversley related to its pH.
Answer:
Magnesium has an outer energy level of n=3 with two electrons in in its energy level. Therefor Magnesium has 2 valance electrons.
Explanation:
We first convert 1.32 atm to torr
1.32 atm = 1003.2 torr
Next, we apply Gay-Lussac's Law:
P₁/T₁ = P₂/ T₂
T₂ = (1003.2 x 34.6) / (760)
T₂ = 45.7 °C
Answer: The acceleration is 50.
Explanation: You can actually re-arrange the formula F = ma to F/m = a. 250/50 = 50.
The average atomic mass of the element rhenium (Re) is 186.208 amu
<h3>Data obtained from the question</h3>
Ffrom the question given above, the following data were obtained:
- Mass of isotope A = 184.955 amu
- Mass of isotope B = 186.956 amu
- Abundance of B = 62.60%
- Abundance of A = 100 - 62.60 = 37.4%
- Average atomic mass =?
<h3>How to determine the average atomic mass </h3>
The average atomic mass of the element can be obtained as illustrated below:
Average atomic mass = [(Mass of A × Abundance of A)/100] + [(Mass of B × Abundance of B)/100]
Average atomic mass = [(184.955 × 37.4)/100] + [(186.956 × 62.60)/100]
Average atomic mass = 186.208 amu
Thus, the average atomic mass of the element is 186.208 amu
