metal + acid --> hydrogen + saltYes?
It's not unicellular organisms replicate!so, asexual
Question:
What are the products formed when magnesium is dissolved in Hydrochloric acid
so..im guessing hydrogen and magnesium chloride

Compare transverse and longitudinal waves (4 marks)
Transvese waves - particles vibrate up and down
longitudinal waves - particles vibrate back and forth
..thats all i know
RealiseNothing
what is that?It is Cowpea
What is the name given to a substance which, when dissolved in water, has a pH of 13?
Transverse waves: the movement of the particles is perpendicular to the direction of the wave i.e. they vibrate up and down
Longitudinal waves: the movement of the particles is parallel to the direction of the wave, basically vibrating back and forth
Both carry energy from A to B

Mg+2HCl->MgCl2+H2

Compare means similarities and differences!
Similarities are they both are carriers of energy and can undergo reflection/refraction/diffraction and interference
Differences: What you guys said about oscillation, plus only transverse waves can be polarised
That's 4 marks. Please remember young grasshoppers
Question
Contrast electromagnetic and mechanical waves and give an example of each (3 marks)

Mg(s) + 2HCl(aq) = MgCl2(s) + H2(g)

Electromagnetic waves do not require a medium through which to travel whereas mechanical waves do. An example of an electromagnetic wave is light. An example of a mechanical wave is sound.Compare means similarities and differences!

They all travel at the speed of light? Plus they don't need a medium obviously
correct.

Speed = 3 x 10^8 m/s
Do not need a medium to travel
propagation is due to electrical and magnetic field
