38K
-391°F
Explanation:
Given temperature:
Temperature of Triton = -235°C
Unknown:
Surface temperature of Triton in °F and Kelvin
Solution:
Temperature is the degree of hotness or coldness of a body.
It is usually measured using units of kelvin, degree Celsius and degree Fahrenheit.
tK = 273 + t°C from °C to K
t°F = 
t°C + 32
tk = temperature in kelvin
t°C = temperature in Celsius
t°F = temperature in Fahrenheit
tK = 273 + (-235) = 38K
t°F = x (-235) + 32 = -423 + 32 = -391°F

The order of the reaction with respect to X is 2.
The statements given ;
1. As Concentration of X is in the rate law equation , changing X will have an effect on the rate of the equation.
2. Rate is proportional to X^2
So if concentration of X is doubled, then rate proportional to (2X)^2 = 4X^2
Rate therefore quadruples when X is doubled
This statement is correct
3. If we divide X/2 then the effect to the rate is (X/2)^2 = X/4 . This will reduce the rate by quarter not half . This statement is wrong.
4. If we multiply by 3
Then rate proportional to (3X)^2 = 9X^2
Rate increases by 9 times. This statement is wrong
Hey
P has 5 valence electrons
O has 6 valence electrons (each for 4 oxygen)
And finally, for every negative charge, there is an additional valence electron
We should add these all up = 5 + 24 + 3 = 32 valence electrons
With this, we can be guided to illustrate the lewis structure as P as central atom and the 3 oxygen each with a single bond with P and 1 oxygen with a double bond with P. We place the valence electrons until octet rule is satisfied,
we will be left with 12 lone pairs for phosphate ion.
