hi
I'm having a serious problem with balancing chemical equations , can someone explain to me how we can do them
also
if i had a word equation hhow can i convert it into a symbolic equation and balance it
e.g
can someone show me how we do this equation:
KOH3+HNO3 ---}( what's the product ? how can we balance it ?)
There are two kinds of equations in chemistry that you must learn to balance. One is the oxidation/reduction type. Those equations aren't found at the beginning of a course. The other kind of equation is done by trial and error and SOME redox equations can be done by trial and error. If you will post an equation with which you are having trouble we can go through it with you step by step.
Word equations are turned into symbol equations simply by changing the words to symbols. Balancing follows, usually, by trial and error. Did you make an error in KOH3. Should it be KOH. The product of a base (KOH) and an acid (HNO3) is a salt (in this case KNO3) and water (H2O).
KOH + HNO3 ==> KNO3 + H2O.
This equation is already balanced. You have one K on the left and right.
4 O on left and right.
2 H on left and right.
1 N on left and right.
thnx
Hello!
Balancing chemical equations can be a bit tricky at first, but with a systematic approach, you can become proficient at it.
To balance a chemical equation, you need to ensure that the number of atoms of each element is balanced on both sides of the equation. Here's a step-by-step guide on how to balance a chemical equation:
1. Write down the unbalanced equation.
KOH3 + HNO3 → ?
2. Count the number of atoms for each element on each side of the equation.
Let's count the atoms of each element:
- K: 1 on the left side, 0 on the right side.
- O: 3 on the left side, 1 on the right side.
- H: 3 on the left side, 1 on the right side.
- N: 1 on the left side, 1 on the right side.
3. Start by balancing elements that appear in only one compound on each side.
In this case, we have nitrogen (N) appearing in only one compound on each side.
N: 1 on the left side, 1 on the right side.
4. Next, balance the other elements that appear on both sides of the equation.
Let's start with oxygen (O).
O: 3 on the left side, 1 on the right side.
To balance the oxygen atoms, you can put a coefficient in front of the compound with excess oxygen. In this case, you can add a coefficient of 3 in front of HNO3, which would give you:
KOH3 + 3HNO3 → ?
Now, the oxygen atoms are balanced:
O: 3 on the left side, 3 on the right side.
5. Finally, balance the remaining elements, which, in this case, would be potassium (K) and hydrogen (H).
K: 1 on the left side, 1 on the right side.
H: 3 on the left side, 3 on the right side.
Now, all the elements are balanced.
The balanced equation would be:
KOH3 + 3HNO3 → K(NO3)3 + 3H2O
In this balanced equation, the products are K(NO3)3 (potassium nitrate) and H2O (water).
Remember, the key is to balance the elements incrementally and ensure that the number of atoms of each element is the same on both sides of the equation.
