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

Chemistry
1 answer:
oksian1 [2.3K]3 years ago
4 0

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

As energy moves out from the sun’s core toward its surface, it first travels by __________, then by __________, and then by ____
Lyrx [107]

Energy leaves the Sun's core and goes by radiation, convection, and radiation on its way to the surface.

Energy leaves the sun's core and initially travels towards the radiation zone. In the radiation zone, the gas is tightly compressed. Here, electromagnetic waves are absorbed and reradiated to transfer energy. Energy can take more than 100,000 years to get through this area because it is so dense.

Thus, energy radiates out initially from the core before being delivered by convection to the outer layers.

What is the main exception in the atomic radius? Explain.
yarga [219]

Answer:

The atomic radius of atoms generally decreases from left to right across a period. There are some small exceptions, such as the oxygen radius being slightly greater than the nitrogen radius. Within a period, protons are added to the nucleus as electrons are being added to the same principal energy level.

hope this helps!
