Answer:
A. The NaCl dissociates into Na+ and Cl- ions, which are able to carry the charge.
Explanation:
This is because when dissolved in water (in aqueous form) ions can move freely and thus they can conduct electricity well. Water by itself is a poor conductor of electricity because it is neutral and therefore does not have the negative and positive charged required to conduct electricity.
109.5 degrees should be the answer you are looking for :D
If the electromagnetic radiation is travelling in vacuum, the velocity of the wave should be 3×10^8 m/s
Using the wave formula,
Velocity=wavelength×frequency,
frequency=(3×10^8)/(0.0107)
Answer:
10.4376 g
Explanation:
First we <u>calculate the sum of the weighings</u>:
- 10.4375 g + 10.4381 g + 10.4373 g + 10.4376 g = 41.7505 g
Then we <u>divide the sum by the number of weighings to calculate the average:</u>
- Average = Sum of weighings / Number of weighings
- 41.7505 g / 4 = 10.4376 g
