One mole of NaCl weighs 58.44 grams
Therefore 1L of one mole of NaCl contains 58.44 grams
1L of 0.2m NaCl contains 58.44x0.2 = 11.69grams
300mL of 0.2m NaCl contains 11.69x0.3 = 3.51 grams
A. transmitting light and displaying colorful imaged.
4 ounces can be evaporated. you need the increase the value by 50% so decrease the water by 50%.
Energy transformations are the processes by which one form of energy is converted to another form.
<h3>What are energy transformations?</h3>
Energy transformations refers to the various ways in which different forms of energy are interconverted.
The given energy transformations are as follows:
- Microwaving popcorn: electromagnetic energy to thermal energy
- Water flowing over a waterfall: potential energy to kinetic energy
- Eating an apple: chemical energy to mechanical energy
- Using an iron: electrical energy to heat energy
- Turning on a car: chemical energy to mechanical energy
- Using a flashlight: chemical energy to light energy
- Fireworks on the 4th of July: chemical energy to light energy
- Turning on the light: electrical energy to light energy
- Playing the drum: mechanical energy to sound energy
- Eating a snack before a run: chemical energy to potential energy
- Making toast in the toaster: electrical energy to heat energy
- Turning on a car radio: electrical energy to sound
- The Sun: nuclear energy to light
- Plant photosynthesis: Light energy tp chemical energy
Therefore, energy transformations are the processes by which one form of energy is converted to another form.

4x = -12
First, divide both sides by 4. / Your problem should look like:
Second, since 4 goes into 3 to get 12, simplify it by 3. / Your problem should look like:
Answer:
x = -3
