I would say it is an acidic solution. Anything with a pH between 0 and 7 is considered acidic, 7 is neutral, and 7-14 is basic.

This would be an acidic solution since the pH level would be under 7, which means that the solution would be acidic

List the following elements from increasing electronegativity: boron, magnesium, calcium, chlorine, argon
pishuonlain [190]

Answer:

The list of elements from increasing electronegativity: Calcium <  magnesium < chlorine < argon < boron.

Explanation:

In the periodic table if you move from left to right there would be an increase in the electronegativity of the elements. If you move from the bottom to the top of the groups in the periodic table the electronegativity increases and if u move to the bottom from down its decreases.

Calcium is in the 2nd group below magnesium so calcium is the least electronegative among given elements then magnesium and then chlorine as it is top of magnesium then argon, as it is right to the chlorine, and boron has the most electronegativity as it is above rest of the elements.

What is amu of 99 % H-1, .2% H-1 and .8% H-3
ankoles [38]

The average atomic mass of your mixture is 1.03 u .

The average atomic mass of H is the weighted average of the atomic masses of its isotopes.  

We multiply the atomic mass of each isotope by a number representing its relative importance (i.e., its % abundance).  

Thus,  

0.99    × 1.01 u = 0.998 u

0.002 × 2.01 u = 0.004 u

0.008 × 3.02 u = <u>0.024 u</u>

            TOTAL =  1.03   u
