The air pressure inside the can is lower compared to that of outside air pressure.

Explanation:

  • In general, the air pressure of an already opened can will be the same as the outside pressure.
  • Since the can is evacuated and remain as vacuum, so there will be no pressure difference in it.
  • If the can opens, air inside the can push the top and escapes to the outside.
  • This is due to high pressure experienced outside the can compare to that of lower pressure inside the can and this may even cause can to collapse itself.

Answer:

Changes in colour of litmus paper.

  • Blue litmus turns red under acidic conditions.
  • Red litmus turns blue under basic conditions.

Noe

PH values:-

  • K=4
  • M=11

K is acidic as pH is <7

Hence K will change the colour of blue litmus paper.

#B

Examples of substances

  • K=Vinegar, Tomatoes.
  • M=Milk of magnesia,Soap

How many moles are in 1.20 times 10^25 atoms of phosphorus
Stels [109]

19.927 moles are in 1.20 times 10^{25} atoms of phosphorus.

<h3>What are moles?</h3>

A mole is defined as 6.02214076 ×10^{23} of some chemical unit, be it atoms, molecules, ions, or others.

1 mole of any substance contain Avogadro's number of molecules so we can calculate the number of moles by dividing the provided number of atoms over Avogadro's number to obtain the number of moles .

Moles= \frac{Atoms}{\;Avogadro's \;number }

Moles=  1.20 X 10^{25} atoms ÷ 6.022 X 10^{23}

= 19.927

Hence, 19.927 moles are in 1.20 times 10^{25} atoms of phosphorus.
