The correct answer for this question is this one: "<span>In transpiration, because some of its properties change, water undergoes a physical change but keeps its identity. In photosynthesis, because its identity changes, water undergoes a chemical change</span>. "
Hope this helps answer your question and have a nice day ahead.
The correct answer is: False.
_______________________________________________________
Water expands (gets larger/ is less dense in solid form than in liquid form) when it freezes).

Under standard temperature and pressure conditions, it is known that 1 mole of a gas occupies 22.4 liters.
From the periodic table:
molar mass of oxygen = 16 gm
molar mass of hydrogen = 1 gm
Thus, the molar mass of water vapor = 2(1) + 16 = 18 gm
18 gm of water occupies 22.4 liters, therefore:
volume occupied by 32.7 gm = (32.7 x 22.4) / 18 = 40.6933 liters
On the Moon<span>, there is (as on </span>Earth) day and night (though the day is as long as month onEarth<span>) and no spot remains </span>dark<span> for longer (except for the pole caps as on </span>Earth<span>). There is, of course, the far </span>side of the Moon<span>, most of which is invisible from </span>Earth.
Answer:
a correct Lewis diagram for CO2 would look something like this
Explanation:
One C and 2 O. Both O have 4 extra dots and 2 lines/bonds to the C. C has no extra dots.
Hope this helps!
