if its 10 degrees outside then it must be cold. then 75 mph that is very windy
Answer:
179.4 g of oyxgen will be produced.
Option 2.
Be careful because the units says L instead of g
Explanation:
Decomposition reaction:
2KClO₃ → 2KCl + 3O₂
2 moles of chlorate can decompose to 2 moles of chloride and 3 moles of oxygen.
We convert the mass to moles, and then we make the rule of three:
458 g / 122.55 g/mol =3.74 moles of chlorate
2 moles of chlorate can produce 3 moles of oxygen
Then, 3.74 moles of chlorate may produce (3.74 .3) / 2 = 5.60 moles of O₂
We convert the moles to mass → 5.60 mol . 32 g / 1mol = 179.4 g
s orbitals have a spherical shape along 3 axes. Fun fact: s orbitals form sigma binds xD
Answer:
a) fraction of carbon−14 in a piece of charcoal remains after 14.0 years.
b) fraction of carbon−14 in a piece of charcoal remains after
c) fraction of carbon−14 in a piece of charcoal remains after .
Explanation:
The fraction of a radioactive isotope remaining at time t is given by:
Taking log both sides:
[A] = fraction at given time t
= half life of the carbon−14 =5,730 years
a)When , t = 14 years
b)When , t =
c)When , t =
Answer:
o- bromo toluene and p- bromo toluene
Explanation:
The two major organic products of the monobromination of toluene are o- bromo toluene and p- bromo toluene.
The reaction is an electrophilic aromatic substitution reaction with bromine acting as the electrophile.
The ortho and para positions of the ring are most activated towards electrophilic aromatic substitution hence the major products.
