Answer:
Cells are the basic structural unit of all living organisms.
Explanation:
Hope this helps, but i'm unsure if it would be multiple choice or not.
Answer:
B. the amount of atoms you contain
Percent to mass
Mass to mole
Divide by small
Multiply 'til whole
Assume 100 g of substance, then 82.2 g N and 17.8 g H.
82.2 g N * (1 mol/14.01 g N) = 5.86 mol N
17.8 g H * (1 mol/1.01 g H) = 17.6 mol H
Divide by the smallest mole
17.6 H / 17.6 = 1 H
5.86 N / 17.6 = 1/3 N
Multiply to make whole number ( x3 in this case)
3 x 1 H = 3H
3 x 1/3 N = 1 N
NH3
Answer:
0.1 M weak acid
Explanation:
The term pH simply means power of hydrogen which is basically a log (the exponent to base 10 of the concentration) of the concentration of the hydrogen ions.
Weak acids have a higher pH since their hydrogen concentration is lower than that of strong acids.
