The trend of elemental radius increases from top to bottom and from right to left. This means Rb is greater than K. Incorporating the positive charges, K+ is smaller than K and Rb+ is smaller than Rb. Thus, the trend in increasing order is K+,K,Rb+,Rb.
Answer:
A Chart Of The Chemical Elements That Displays Them In Rows Horizontally In Order Of Increasing Atomic Number And Vertically According To Similarity Of The Chemical Properties Of Their Atoms.
If ion charges <u>decreases</u> then less attraction and energy <u>decreases</u>.
If radii <u>increases</u> then there is more distance , less attraction result of this energy <u>increases </u>
so energy increases as ion charges increases and radii decreases
Answer: Because it is a giant fire ball
Answer:
0.4762 J/g°C.
Explanation:
<em>The amount of heat released to water = Q = m.c.ΔT.</em>
where, m is the mass of water (m = 15.0 g).
c is the specific heat capacity of water = ??? J/g°C.
ΔT is the temperature difference = (final T - initial T = 37.0°C - 30.0°C = 7.0°C).
<em>∴ The specific heat capacity of water = c = Q/m.ΔT</em> = (50.0 J)/(15.0 g)(7.0°C) = <em>0.4762 J/g°C.</em>
