Is H2 O2 h2o balanced? The obtained result indicates that the oxygen atom is not equal on both sides. Thus the reaction is not balanced. The balanced reaction has the number of atoms involved in reaction in reactants as well as the product is equal. What type of reaction is Na h2o? In what way […]
How would you determine if your pipette were pipetting accurately?
How would you determine if your pipette were pipetting accurately? It’s easy to measure your pipetting accuracy – just pipette the same volume of water ten times onto a tared balance, note the weight each time. Then measure the relative standard deviation in the dispensed masses by calculating the standard deviation and expressing it as […]
Why would the amount of bonds change the bond length?
Why would the amount of bonds change the bond length? The higher the bond order, the stronger the pull between the two atoms and the shorter the bond length. Generally, the length of the bond between two atoms is approximately the sum of the covalent radii of the two atoms. Therefore, bond length increases in […]
