Answer:
A
Explanation:
The Charles law states that the volume of an ideal gas increases when temperature is increased under constant pressure. The pressure inside the balloon is always equal to the atmospheric pressure. Therefore answer A demonstrate the Charles law.
Answer:
Exothermic
Explanation:
I think it is exothermic because heat is being released
Electric hidro because he has the highest osmolarity
Number 1: (A.)
Number 2: (A.)
Number 3: (B.)
I'm probably wrong but that is what i think
Answer is (1) - N
<em>Explanation:</em>
I think the given chart is electronegativity chart.
Electronegativity is a
value that tells us how an atom can attract electrons towards itself. <span><u>If the electronegativity is
high, then the attraction to the electrons is high unless the attraction to the
electrons is low. </u>
Electronegativity increases from left to right of the periodic table and decreases from up to down.
Hence, highest electronegative atom is F which has 4.0 and lowest electronegative atoms are Cs and Fr (0.7).
The electronegativity values for given atoms are
N - 3.0
Na - 0.9
P - 2.1
Pt - 2.2
