The coorect answer would be A
Answer:
A
Explanation:
the number of molecule won't be twice as fructose has 12 hydrogen molecules and lactose has 22 hydrogen molecules
Answer:
The non metals form anions…
Explaination: Generally non-metals have 4 to 7 electrons in their outermost or valence shell.(Exception Carbon, silicon, etc. they have 4 electrons). Hence to achieve their octet (to have 8 electrons in their valence shell) they accept 1,2 or 3 electrons from other elements accordingly, thereby having -1, -2 or -3 charge on them (turning from neutral atoms to charged anions).
Extra info: non metals react with metals by forming anions and form ionic molecule generally but when non metals react with other non metals they form covalent molecule due to ‘sharing’ of electrons.

A real gas behaves least like an ideal gas under the conditions of low temperature and high pressure.
This is because at low temperature and high pressure molecules of gas will have negligible kinetic energy and strong force of attraction. Thus, real gas will not behave like an ideal gas.
Whereas at high temperature and low pressure a real gas will behave like an ideal gas.
