What the steps for balancing chemical equations?
Which of the following are steps for balancing chemical equations? Check all that apply. B. Choose coefficients that will balance the equation. And D. Recheck the numbers of each atom on each side of the equation to make sure the sides are equal. Apex
What method do you use to balance a chemical equation?
PARTIAL EQUATION METHOD:----- When equations contain many reactants and products they cannot be balanced by the hit and trial method. They are then balanced by the partial equation method. In this method the overall reaction is assumed to take place through two or more simpler reactions, which can be represented by partial equations. The steps involved are: Steps and problem * The given chemical equation is split into two or more partial equations. * Each partial equation is separately balanced by the hit and trial method. * These balanced partial equations are multiplied with suitable coefficients in order to exactly cancel out those common substances which do not appear in the overall chemical equations. * The balanced partial equations so obtained, are added to arrive at the balanced chemical equation. PROBLEM Balance the equation, NaOH + Cl2---------------------------------> NaCl + NaClO3 + H2O by partial equation method. SOLUTION The given skeleton equation can be split into two partial equations. Partial eq.1 NaOH + Cl2---------------------------------> NaCl + NaClO + H2O Partial eq.2 NaOCl ------------------------------> NaCl + NaClO3 The two partial equations are balanced by hit and trial method. Balanced partial eq.1 2NaOH + Cl2---------------------------------> NaCl + NaClO + H2O Balanced partial eq.2 3NaOCl ---------------------------------> 2NaCl + NaClO3 NaClO does not appear in the overall equation and so to cancel it, the partial balanced equation 1 is multiplied by 3 and the two equations are added to get the overall balanced equation. 2 NaOH + Cl2---------------------------------> NaCl + NaClO + H2O * 3 3NaOCl ---------------------------------> 2NaCl + NaClO3 FINALLY 6NaOH + 3 Cl2---------------------------------> 5NaCl + NaClO3 + 3H2O
After the first steps in writing an equation the eqaution is balanced by?
adjusting coefficients to the smallest whole-number ratio.
What are the steps to prove that a burning of a candle is physical as well as a chemical change?
1. Melting of the candle is a physical change. 2. Burning and thermal decomposition are chemical changes.
How are all chemical cycles similar?
All of the chemical cycles are similar in the fact that they are perform the same type of steps. All of the chemical cycles also serve the same purpose which is to keep the amount of elements on the planet in perfect order.

Are not steps for balancing chemical equations?
(Apex) C. Add all the elements togetherD. Subtract the total amount of elements from the products
Changing subscripts is one of the steps of balancing a chemical equation.?
f fales
What are multi step equations?
They are equations that involve many steps to find the solution.
Can rational equations steps to solving be eliminated or changed in any way?
Simultaneous equations can also be solved by substitution or graphically
What are the steps on solving equations?
The answer will depend very much on the nature of the equation. The steps required for a one-step equation are very different from the steps required for a partial differential equation. For some equations there are no straightforward analytical methods of solution: only numerical methods.
What is the shorthand form for describing chemical reactions?
write down the formula for any substance entering into reaction.place the (+) sign between the formulas as needed and put the yield after the last one.
What are the steps to solving multistep equations?
the contents of parenthesesexponential termsmultiplication and divisionaddition and subtraction
Can any of these steps be eliminated solving rational equations?
would you add any steps to make it easier or to make it easier to understand
What was the name on the writing method and how it was?
There are five steps of the writing process. Prewriting, drafting, revising, proofreading and publishing are all important steps to be successful at the writing process.
What are the three steps in writing?
The three steps in writing typically involve prewriting (planning and brainstorming), drafting (putting your thoughts into writing), and revising/editing (reviewing and refining your work).
What are some steps to physical and chemical change?
Physical and chemical?! Right on!
