In acidic solition, the coefficient of permanganate ion in the balanced redox equation is 2.
<h3>How can a redox equation be balanced?</h3>
A redox equation showing a reduction and an oxidation reaction occurring simultaneously.
To balance redox equations, the atoms reacting as well as the electrons transferred are balanced.
In the reaction of permanganate ion and bromide ion in acidic solution, the balanced redox equation is given as follows:
- 2 MnO4- + 10Br- + 16 H+ → 2 Mn2+ 5 Br2 + 8 H2O
Therefore, the coefficient of permanganate ion in the balanced redox equation is 2.

According to Graham's law of effusion, the ratio of the rates of effusion of two different molecules is equal to the square root of the reciprocal of the molar masses of the molecules. gas a is faster than B since it is lighter than B. Hence we expect a molar mass less than 17. we have the equation 1/0.68 =
where x is the molar mass of gas A. This is equal to 7.86 grams.
Answer:
(CH3)2N(CH2)
Explanation:
A hydrogen bond occurs in a molecule when hydrogen is covalently bonded to a highly electronegative atom.
That means that if we are looking for a compound in which there is no hydrogen bonding, we are actually looking for the compound in which hydrogen is not directly linked to an electronegative atom.
If we look at the options carefully, the compound that has such characteristic is only (CH3)2N(CH2) which is a tertiary amine. The nitrogen is directly linked to three alkyl groups and no hydrogen atom hence the molecule does not exhibit hydrogen bonding.
