Sanitising is very important in a house hold but most importantly in the kitchen we have to always keep things clean and sanitise for the sake of our health and the people around us
False
Explanation:
Sound waves are longitudinal mechanical waves.
Mechanical waves are waves that requires a medium to propagate them.
- A transverse wave is a wave that is propagated perpendicularly to its source.
- An example is electromagnetic radiation.
- A longitudinal wave is a wave that is directed parallel to their source.
- Sound wave is a longitudinal wave.
- It has series of rarefaction and compression along its travel path.
- Rarefaction are areas of sparse particles.
- Compression are areas with dense particles.

Answer:
Explanation:
The given reaction equation is:
2A + 4B → C + 3D
We know the mass of compound A in the reaction above. We are to find the mass of compound D.
We simply work from the known mass to calculate the mass of the unkown compound D
Using the mole concept, we can find the unknown mass.
Procedures
- We first find the molar mass of the compound A from the atomic units of the constituent elements.
- We then use the molar mass of A to calculate its number of moles using the expression below:
Number of moles of A = 
- Using the known number of moles of A, we can work out the number of moles of D.
From the balanced equation of the reaction, it is shown that:
2 moles of compound A was used up to produced 3 moles of D
Then
x number of moles of A would give the number of moles of D
- Now that we know the number of moles of D, we can find its mass using the expression below:
Mass of D = number of moles of D x molar mass of D
