H20 and c20 were brothers and sisters before ch3ch2nh2 even existed
Answer:
it is a gas not a mixture
Since sodium chloride contains both a metal AND a nonmetal, the combination of those would result in an ionic bond.
Spring force is given be kx.
Where k is spring constant and x is the distance moved.
Using this relation,
Answer:
34.59 % Al; 61.54 % O; 3.877 % H
Explanation:
% by mass = mass of element/total mass × 100 %
Let's rewrite the formula of Al(OH)₃ as AlO₃H₃.
Set up a table for easy calculation.
<u>Atom</u> <u> Mass/u </u> <u>Subtotal
</u>
1Al 1 × 26.98 = 26.98 u
3O 3 × 16.00 = 48.00 u
3H 3 × 1.008 = <u> 3.024 u
</u>
Total = 78.004 u
Mass % Al = 26.98/78.004 × 100 % = 34.59 %
Mass % O = 48.00/78.004 × 100 % = 61.54 %
Mass % H = 3.024/78.004 × 100 % = 3.877 %
