<em> Hi mate, here is ur answer:</em>
<em />
<em>You can </em><em>dissolve</em><em> more </em><em>salt</em><em> in </em><em>hot water</em><em> because in hot water, </em><em>molecules </em><em>move faster than </em><em>cold water</em><em> because of the </em><em>higher energy</em><em>, as a result the molecules of hot water move fast and </em><em>settles down</em><em>. As they settle fast, it is easy for higher amount of salt to dissolve in hot water. </em>
<em>HOPE THIS HELPS U</em>
<em>:) WISHING U A GREAT DAY AHEAD </em>
Answer:
More energy is required to raise its temperature. Therefore, temperature does not stay the same when heat energy increases.
Matter: radio, car, flashlight, textbook, human
Not matter: everything besides the matter items
It is bases on "Atomic number"
In short, Your Answer would be Option B
Hope this helps!
Answer:
The empirical formula is CH3O2
Explanation:
From The question, number of moles of CO2= 4.89/44=0.111mol
Number of moles of H2O=3/18= 0.1667moles
Since 1mole of CO2 contains 1mole of carbon and 2 moles of O2,
Implies that there 0.111 moles of C and 0.222moles of O2
Similarly also 0.1667moles of water contains 2 moles of H2 hence = 0.333 moles of H2
Dividing by smallest number= 0.111mol
For C = 0.111/0.111= 1
For H = 0.333/ 0.111= 3
For O = 0.222/0.111= 2
Hence the empirical formula= CH3O2
