Limiting Reactant

 Limiting Reactant MCQs  for Grade 11

Here is the most important list of mcqs that can be asked from the lesson Limiting Reactant.

 Alcohol ( R-OH)

Alcohol is one of the demanding chemical products in the current world. As it serves the precursor for many other products its production has been incresing. Not only for making other chemical substances, but for making alcoholic beverages also, its use has been increased. 

To make know the students about alcohol, the course has included the topic "ALCOHOL".

Most of the students feel difficulty as they do not know the exact what happens in the chemical reaction.

To simplify the learning here I have prepared the complete note on Alcohol. Enjoy learning.

Here is one of the standard sets of questions that were asked in Buddhabhumi municipality.

This paper is standard one as we can see the last year's compulsory mathematics paper in the standard format. Hope you will absolutely follow this model for your upcoming examination and secure a good GPA.

Enjoy learning.

Common Mistakes made by students in high school mathematics.

 As a mathematics lover as well as a teacher, I have seen many students making simple but recurrent mistakes in school-level mathematics. These silly mistakes make the students score low in their examinations.

for example:

solve x(x-3) = 0

here most of the students solve like this

  x-3 =0

or, x= 3

But it's wrong. The reason behind this is 

when we open the brackets we have x^2 which means it becomes a quadratic equation. And we should know that each quadratic equation has two definite solutions. 

Therefore, x= 0 and 3 will be the true solution.

We can find such mistakes in large numbers in mathematics. this is just due to lack of concept on the topic.

What to do then??

Simple, grab the concept on the topic.

You can find more such recurring mistakes and their remedy in the specially designed video.

 SEE Question papers of 2078 B.S.

Most of the teachers as well as students are struggling to find the question papers, thinking about the problem, we have posted the papers here. So that you all a little bit get relaxed.

Here we have the mathematics question paper that was asked last year ( 2078 B.S.)
