A chemist needs to know the concentration of some NaOH that is in the laboratory. To find this out, she titrates a 50.0 mL sampl
RoseWind [281]

Answer: 2.4 M

Explanation:

According to the neutralization law,

n_1M_1V_1=n_2M_2V_2

where,

M_1 = molarity of Hl solution = 3.5 M

V_1 = volume of HCl solution = 34.3 ml

M_2 = molarity of NaOH solution = ?

V_2 = volume of NaOH solution = 50 ml

n_1 = valency of HCl = 1

n_2 = valency of NaOH = 1

1\times 3.5M\times 34.3=1\times M_2\times 50

M_2=2.4

Therefore, the concentration of NaOH solution is 2.4 M.

Which element is least likely to undergo a chemical reaction
Maksim231197 [3]

Answer:

Neon is the least likely to undergo chemical reaction.

Explanation:

The other elements given in the option do not have 8 electrons in their outermost shell, so they will be quite willing to undergo chemical reactions in order to become stable.

The orbital period of planet Venus is 0.62 years. What is its distance from the sun?
Vikki [24]

Kepler's third law shows the relationship between the orbital period of an object and the distance between the object and the object it orbits.

The simplified version of this law is: P^2 = a^3

Where,

P = period of the orbit in years = 0.62 years

a = average distance from the object to the object it orbits in AU. The astronomical unit AU is a unit of length which is roughly equivalent to the distance from Earth to the Sun.

Therefore calculating for a:

0.62 ^ 2 = a ^ 3

a = 0.62 ^ (2/3)

a = 0.727 AU = 0.72 AU

Therefore we can interpret this as: The distance from Venus to the Sun is about 72% of the distance from Earth to Sun.

<span>Answer: B. 0.72 AU</span>
