Answer:
Yttrium barium copper oxide (YBCO) is a family of crystalline chemical compounds, famous for displaying high-temperature superconductivity.It includes the first material ever discovered to become superconducting above the boiling point of liquid nitrogen (77 K) at about 92 K.Many YBCO compounds have the general formula Y Ba 2 Cu 3 O 7−x (also known as Y123),

Answer:
put a filter to see if there is any stagering solution
Explanation:
Answer:
r = k × [A] × [B]
Explanation:
To determine the rate law, we simply use the slow step reaction equation. The slow step is the rate determining step in the reaction.
A+B→AB
And as we know, the rate of the reaction is proportional directly to the product of the concentration of the reactants which concentration is changing over the course of the reaction.
r = k × [A] × [B]
Where r = rate of reaction
k = reaction rate constant
[A] = Concentration of molecule A
[B] = Concentration of molecule B
The grams of N2 that are required to produce 100.0 l of NH3 at STP
At stp 1moles = 22.4 l. what about 100.0 L of NH3
= 100 / 22.4 lx1 moles = 4.46 moles of NH3
write the reacting equation
N2+3H2 =2NH3
by use of mole ratio between N2 to NH3 which is 1:2 the moles of N2 =4.46/2 =2.23 moles of N2
mass = moles x molar mass
= 2.23moles x 28 g/mol = 62.4 grams
