Balance each element on at a time by placing coefficients in front of the formulas. No coefficient is written for a 1. It is best to begin by balancing elements that only appear in one formula on each side of the equation. NEVER change the subscripts in a chemical formula – you can on...
1. You have two atoms of Cr on both sides of the oxidation equation - but you have lost 2 on the RHS of the full equation. 2. No idea why do you think it should be 6 INSTEAD of 3. 3 is wrong - your reduction reaction after being multiplied by 3 will give you 6 atoms of Br...
Now, you have a balanced equation for the overall reaction of photosynthesis.

Despite reliability and efficiency being claimed by manufacturers of said machines, small and medium-sized firms continue to hesitate to invest them due cost-related reasons. It describes constant improvement of these machines particularly in speed and quality. Remarks from Rob Goleniowski of Roland ...

If the right coefficient is chosen, we can balance the number of atoms of the elements participating in the reaction. Answer and Explanation: The given chemical equation is: {eq}\rm C_6H_{12}O_6 + O_2 \longrightarrow CO_2 + H_2O {/eq} To b...
These are the comments that you may hear when your students are given the following equation to balance:KClO3 + HCl -> KCl + H2O + Cl2 + ClO2The source of this reaction was M. McMillan in A Demonstration-A-Day (Calhoun Scientific: Battle Creek, MI, 1992). The author suggests that ...
(-), however, must become water, H2O, as a byproduct, and the water cannot form with hydrogen atoms, H(+). Therefore, protons, H(+) must be added to the left side of the equation. The balanced half-reaction now becomes MnO4(-) + 8 H(+) + 5 e → Mn(2+) + 4 H2O, where...
In this example, all of the variables mentioned above represent different cost variables with different values. A consumer may value the shoes at $50/pair; if the company determines its cost value is $75/pair, the company must assess how to rebalance the equation. Alternatively, charging a cu...
