neptune has an average distance to the sun of 30.06 au in two or more complete sentences explain how to calculate the orbital period of neptune ​

Answers

Answer:

As per Kepler's law we know that

\frac{T_1^2}{T_2^2} = \frac{R_1^3}{R_2^3}T22T12=R23R13

as we know that for earth the time period is 1 year and its distance is 1 AUnow from above formula we can saylet the time period of Neptune is T and its distance is given as R = 30.06 AUnow we will have\frac{1^2}{T^2} = \frac{1^3}{30.06^3}T212=30.06313by rearranging the above equation we haveT^2 = (30.06)^3T2=(30.06)3T = 164.8 yearsT=164.8years

so it will have time period of 164.8 years

Melting and Boiling Point Determination

The physical properties of a substance can be used to establish its purity. These properties include the melting point and boiling point. Different substances tend to have different melting and boiling points, and any pure substance will have a specific melting and boiling point.

How many particles are in 4g of NaCl? (1mol of NaCl = 58g) – 2 step conversion

Answers

Answer:

4.16 * 10²⁴ particles

Explanation:

1. We convert from grams to moles

4 g NaCl / 58 g of NaCl = 0.0689655172 moles

-> 0.0690 moles

2. Now we will convert from moles to particles by multiplying by avogadro's number..

0.0690 * 6.022 *10²³ = 4.15518 * 10²⁴ particles or 4.16 * 10²⁴ particles
