The relationship between Fahrenheit and Celsius is:
°F = 1.8*°C + 32
If we differentiate the given expression to find the relationship between a unit change of °F and °C, we get:
Δ°F = 1.8*Δ°C
This means that a change in 1 degree Fahrenheit is equivalent to a change of 1.8 degrees Celsius. Moreover, a one degree change in Fahrenheit is the same as a one-degree change on the Rankine scale, so, ranking the scales in order from higher change to lower change:
1) Fahrenheit = Rankine
2) Celsius = Kelvin
Emerald can be described as a transparent, green coloured gem stone made up of mineral beryl together with trace amount of chromium or sometimes vanadium having chemical formula as
.
<h3>
What is the
significant of Emerald ?</h3>
Through time, the emerald has been known as a symbol of truth and love.
In ancient Greece and Rome, emerald was said to be the gemstone of the goddess Venus, purveyor of love and hope.
On the other side of the world, emeralds were revered by the Incas and believed by the Egyptians to be a source of eternal life.

Explanation:
Rate law says that rate of a reaction is directly proportional to the concentration of the reactants each raised to a stoichiometric coefficient determined experimentally called as order.
(1) is second order in B and overall third order.
2A + B → C
Order of the reaction = sum of stoichiometric coefficient
= x + 2 = 3
x = 1
Rate of the reaction =R
![R=k[A]^1[B]^2](https://tex.z-dn.net/?f=R%3Dk%5BA%5D%5E1%5BB%5D%5E2)
(2) is zero order in A and first order in B.
2A + B → C
Rate of the reaction =R
![R=k[A]^0[B]^1=k[B]^1](https://tex.z-dn.net/?f=R%3Dk%5BA%5D%5E0%5BB%5D%5E1%3Dk%5BB%5D%5E1)
Order of the reaction = sum of stoichiometric coefficient
= 0 + 1 = 1
(3) is zero order in both A and B .
2A + B → C
Order of the reaction = sum of stoichiometric coefficient
= 0 + 0 = 0
Rate of the reaction =R
![R=k[A]^0[B]^0=k](https://tex.z-dn.net/?f=R%3Dk%5BA%5D%5E0%5BB%5D%5E0%3Dk)
(4) is first order in A and overall zero order.
2A + B → C
Order of the reaction = sum of stoichiometric coefficient
= 1 + x = 0
x = -1
Rate of the reaction = R
![R=k[A]^1[B]^{-1}](https://tex.z-dn.net/?f=R%3Dk%5BA%5D%5E1%5BB%5D%5E%7B-1%7D)
Answer:
Plastic is better because it doesn't melt in the microwave but aluminum burns in the microwave
Explanation:
Answer:
KBr, FeF3
Explanation:
Potassium ion (K+) + bromide ion (Br-) make the ionic compound KBr
Iron (III) ion (Fe3+) + 3 fluoride ions (F-) make the ionic compound FeF3
NH3 has covalent bonds so it isn't ionic
Mg12 is an elemental compound
