Explanation:
3Ca(s) + 2AlCl3(aq) -> 3CaCl2(aq) + 2Al(s)
According to the question, Ca is the limiting reactant.
Therefore, we equate Ca to Aluminium which is the product whose mass we want to find
Molar mass of Ca- 40g/mol
". ". of Al- 27g/mol
3Ca --> 2Al
3×40 --> 2×27
9.2 --> x
x = 9.2×2×27= 496.8÷120=4.14
Magnetic is a physical property.
Explanation:
In the extreme winters , the water inside pipes freeze, on freezing it's(water molecule) density decreases and volume increases and therefore, the ice then expands and pushes the water towards the faucet, causing high pressure buildup in the pipe and after a limit the pipe burst. This is what happened to the family in Ottawa, where winters are chilly.
Answer:
C) Steam condensing on a mirror
Explanation:
This was just a change in the physical state.
Answer:
The pH of a solution with a (H+] = 0.80 M is 
Explanation:
As we know
pH = -[log H+]
Substituting the value of H+ ion concentration in the above equation, we get -
pH = -log [0.80]
pH ![= -[-0.096] = 0.096 = 9.6 e^{-2}](https://tex.z-dn.net/?f=%3D%20-%5B-0.096%5D%20%3D%200.096%20%20%3D%209.6%20e%5E%7B-2%7D)
