Which of the following are true regarding balancing chemical equations?
|
A) It takes practice in the form of trial and error to balance chemical equations |
||
|
B) The law of conservation of matter should be applied by counting the number of atoms of every element on each side of the equation |
||
|
C) Save oxygen and hydrogen for last and balance the chemical formulas by placing coefficients in front of the formulas |
||
|
D) All of the above |
Homework Answers
It's d all of the above because first we should do tiral with some stiochiometry and see whether the equation is balanced or not and in chemical reaction no atom can be destroyed so law of conservation of matter we have to see and oxygen and hydrogen can be balance easily so we have .to balance it last
