Answer:
20 kmp
Explanation:
because if you divide 50 with 2.5 you get the speed per hour
Hello!
(Missing)
<span>A) Put a coefficient of 3 on Al
B) Put a coefficient of 3 on O2
C) Put a coefficient of 2 on O2
D) Put a coefficient of 3 on Al2O3
A good first step to balance this reaction is Put a coefficient of 3 on O</span>₂.
All the other options don't balance an atom but putting a coefficient of 3 on O₂ achieves the goal of starting to balance Oxygen on both sides of the equation. The next step after that would be to put a coefficient of 2 on Al₂O₃ and there would be 6 Oxygen atoms on both sides of the equation.
Have a nice day!
Electrons are negatively charged. If you remove negative particles, the leftover atom is positive and positive is really just another word for "less negative".
The total number of valence electrons is 20.(1 from hydrogen, 5 from nitrogen, and 7 from each fluorine so 14 for both) connect all the atoms with a single bond( each bond counts as 2) so far there is 6 electrons so you need to fill in the rest of the 14 and you get the result in the picture.
Ka and Kb values of weak acids and weak bases are small.
This is because weak acids and weak bases do not dissociate completely, favoring the reactants more than dissociating into the product of H+ or OH-.
