7.64 X 10^19 oxygen atoms
I personally try to balance the equation without looking at the given coefficients in the unbalanced reaction and this is my result:
2 C2H14+11 O2--> 4 CO2+14 H2O
I think none of the given answers are correct, and the answer is obviously 11.
Hope this will help :))
Answer: D)The distance from Earth and mass of ISS exert negligible gravitational force on the astronaut.
Explanation:
The distance from Earth and mass of ISS exert negligible gravitational force on the astronaut. Gravity is a very weak force and varies with mass and the inverse square of distance. The astronaut's distance from Earth and the relative small mass of ISS result in gravitational force near zero.
Answer:
D.When the boiling points of the components are different
Explanation:
I believe the formal name for this procedure is actually distillation.
Answer:
See explanation
Explanation:
The major difference between distance and displacement is that distance is a scalar quantity while displacement is a vector quantity. Scalar quantities have magnitude without direction while vector quantities have both magnitude and direction.
The distance covered by Benjamina in both cases just refer to the difference in her position at each time without reference to the direction in which she changed her position.
Her displacement will clearly mention the direction in which she moved both when she walked to the front door of her apartment and when she walked to a friend's apartment.
