- By changing three atom bond angle , we can change molecular polarity. if bond angle is 120° and all atom has same electronegativity, the resultant polarity ( dipole moment ) become zero. we can change bond anngle either less than or greater than 120°, but not exactly 120
- Replacing one or more atom with different atoms having electro negativity values also make molecular poles.
- By placing molecules under external electric field or magnetic field also causes to the molecule.
Answer:
equal to [OH-]
Hydrogen ion concentration is more conveniently expressed as pH, which is the logarithm of the reciprocal of the hydrogen ion concentration in gram moles per liter. Thus, in a neutral solution the hydrogen ion (H+) and the hydroxyl ion (OH−)
Answer: It's element, they can't be broken down to anything other than what they are.
DO NOT PUT YOUR ANSWER AS WHAT THE OTHER PERSON WHO ANSWERED PICKED BECAUSE THEY'RE ANSWER IS WRONG!
Answer:
Moles = Mass / Mr
Moles = Concentration x Volume
Explanation:
Moles can be worked out in several ways depending on the information you are given. Some of the equations containing moles are:
Moles = Mass / Mr
Moles = Concentration x Volume
Synthesis reaction is a reaction in which several reactants combine to form one product. Eg; hydrogen and oxygen combining to make water.
In this reaction , hydrogen and oxygen are the several reactants that combine together to form only one product (water)
Hope this helps;)
