900J
Explanation:
Well, kinetic energy is expressed through the equation:
KE
=
1
2
m
v
2
m
is the mass of the object in kilograms
v
is the velocity of the object in meters per second
So, we plug in the values, which are
m
=
0.02
kg
v
=
300
m/s
And we get,
KE
=
1
2
⋅
0.02
kg

(
300

This is kind of a pretty easy question:
- In order to get the number of atoms/entities of Neon, you will have to turn that 1009g of Neon into moles
-And then you have to use the moles and calculate it using Avogadro's Number which is 6.02 x 10^23
number of moles = mass/molar mass of element/compound
n = 1009g/20.18g/mol
n = 50 mol
Number of atoms/entities = 50 x (6.02 x 10^23)
Number of atoms in 1009g of neon is 3.01 x 10^25 (scientific notation because its a really long number)
Answer:
The answer to your question is letter A. 65.9%
Explanation:
Data
actual yield = 1.20 g
theoretical yield = 1.82 g
Formula
percentage yield =
Substitution
percentage yield =
Simplification and result
percentage yield = 0.6593 x 100
percentage yield = 65.9 %
