How does gravity affect the rain during a rainstorm?
Advocard [28]

Gravity is the force of attraction between two objects, and Earth's gravity pulls matter downward, toward its center. It pulls precipitation down from clouds and pulls water downhill. Gravity also moves air and ocean water. ... Gravity pulls denser air and water downward, forcing less dense air and water to move upward.

The compound 1,1-difluoroethane decomposes at elevated temperatures to give fluoroethylene and hydrogen fluoride: CH3CHF2(g) → C
Maru [420]

Answer : The final temperature would be, 791.1 K

Explanation :

According to the Arrhenius equation,

K=A\times e^{\frac{-Ea}{RT}}

or,

\log (\frac{K_2}{K_1})=\frac{Ea}{2.303\times R}[\frac{1}{T_1}-\frac{1}{T_2}]

where,

K_1 = rate constant at 460^oC = 5.8\times 10^{-6}s^{-1}

K_2 = rate constant at T_2 = 4\times K_1

Ea = activation energy for the reaction = 265 kJ/mol = 265000 J/mol

R = gas constant = 8.314 J/mole.K

T_1 = initial temperature = 460^oC=273+460=733K

T_2 = final temperature = ?

Now put all the given values in this formula, we get:

\log (\frac{4\times K_1}{K_1})=\frac{265000J/mol}{2.303\times 8.314J/mole.K}[\frac{1}{733K}-\frac{1}{T_2}]

T_2=791.1K

Therefore, the final temperature would be, 791.1 K

Antimony has 2 naturally occurring isotopes. The mass of antimony-121 is 120.904 amu and the mass of antimony-123 is 122.904 amu
Sav [38]
Wow, now this one is a hard one, took me quite a while to figure it out but here it is:
120.904(x)+122.904(1-x)=121.76 \\ 
120.904x-122.904x+122.904=121.76 \\ 
-2x+122.904=121.76 \\ 
-2x=-1.144 \\ 
x=.572  \\ 
1-.572=.428
The abundances of the two isotopes is:
Antimony-121 = 57.2%
Antimony-123 = 42.8%

From the illustration of the potassium atom fill in the periodic table selection
Phoenix [80]

Answer:

2 electrons

8 electrons

8 electrons

1 electron (just count in the rings for these ones)

19 protons (it says "P=19" in the middle. The P stands for Protons)

K (it's from Latin medieval Latin "kalium")

39 (add proton and neutron amounts to get the approximate atomic mass--electrons are negligible)
