Given mass of tungsten, W = 415 g
Molar mass of tungsten, W = 183.85 g/mol
Calculating moles of tungsten from mass and molar mass:
Answer:
Element
Explanation:
Because elements can be made with only one atom the rest of the answers cant be
<h2><u>

In Step 5, you will calculate H+/OH– ratios for more extreme pH solutions. Find the concentration of H+ ions to OH– ions listed in Table B of your Student Guide for a solution at a pH = 2. Then divide the H+ concentration by the OH– concentration. Record these concentrations and ratio in Table C.
What is the concentration of H+ ions at a pH = 2?
<h3>
0.01 mol/L </h3>
What is the concentration of OH– ions at a pH = 2?

What is the ratio of H+ ions to OH– ions at a pH = 2?
<h3>
10,000,000,000 : 1</h3>

Answer:
It is not "strong acids have a low pH"
Explanation:
I feel it should because that is a true statement but for Primavera it is wrong.
Answer:
The correct answer is 2.2 mL.
Explanation:
Given:
Average: 2.9 mL
SD: 0.71 mL
We can define a 1 SD range in which the value of volume (in mL) will be comprised:
Volume (mL) = Average ± SD = (2.9 ± 0.7) mL
Maximum value= Average + SD= 2.9 + 0.7 mL = 3.6 mL
Minimum value= Average - SD = 2.9 - 0.7 mL = 2.2 mL
Thus, the minimum value within a 1 SD range of the average is 2.2 mL
