b. atomic radius
as it goes increases when it goes down the periodic table, it decreases when going left to right. all the others decrease while going down the table.
if it helps you to remember, everything here besides atomic radius has an e in it. and if you make a connection with it to electrons, they are negative, which means they would decrease going down the table. so e=decrease while going down
thats what helped me remember it, so i hope this technique could help you too.
<span>3. relate to properties of elements and how they may react.
Periodic trends are specific patterns that are present in the periodic table that include size, electronic properties, melting point, electronegativity and metallic character. The trends exist due to the similar atomic structure of the elements within each group family.</span>
The lines occurring in an emission spectrum are all electromagnetic waves, which means that their speed in a vacuum is
3 x 10⁸ m/s
We can use the equation,
v = fλ
which relates the velocity of a wave to the frequency and wavelength. Substituting values,
3 x 10⁸ = f * 434 x 10⁻⁹
f = 6.91 x 10¹⁴ Hz
The frequency of the wave will be 6.91 x 10¹⁴ oscillations per second.
from ICE table
H2(g) + I2 (g )↔ 2HI(g)
equ 0.958 0.877 0.02 first mix1
0.621 0.621 0.101 sec mix2
Kp1 = P(HI)^2 / p(H2)*p(I2) for mix 1
= 0.02^2 / 0.958*0.877
= 4.8x10^-4
Kp2 = P(HI)^2 / P(H2)* P(I2) for mix 2
= 0.101^2/ 0.621*0.621
= 0.0265
we can see that Kp1< Kp2 that means that the sec mixture is not at equilibrium. It will go left to reduce its products and increase reactant to reduce the Kp value to achieve equilibrium.
and the partial pressure of Hi when mix 2 reach equilibrium is:
4.8x10^-4 = P(Hi)^2 / (0.621*0.621)
∴ P(Hi) at equilibrium = 0.0136 atm
Answer:
B
Explanation:
All the properties listed above is for carbon ii oxide.
It is odorless, colorless and poisonous
It is formed from the incomplete combustion of fossil fuels
And it can actually interfere with the blood’s ability to carry oxygen
