Alkali Metals (Group 1) elements experience an increase in the vigour of their reaction in water as they go down the group (as the atomic number increase). As such the most reactive Alkali Metal would be
FRANCIUM, which is at the base of Group One.
Quite frankly, you do not want Francium to react with water- that's a huge explosion on your hand.

Explanation:
The negative effects of video games include:
1. Social disconnection- One negative effect of video games is that it brings about social disconnection. Video games are typically addictive and this leads to the individual playing the game gradually disconnecting from the social life.

3. Wrong values - Some video games instill wrong values in children. Such values include violence, aggression and vengeance.
4. Negative academic achievement - Students who play video games a lot tend to have a negative academic achievement as the time they could have used in reading or studying is used for playing games and thus tends to have an effect on the performance in school.
5. Health hazards- Video games may lead to health hazards- such as nerve compression, obesity, and video-induced seizures.
The positive effect of video games are:
1. Problem solving - Video games train ones brain to be creative and also come up with solution to challenges.
2. Quick thinking - Video games help one to think quickly in order to solve challenges and overcome obstacles.
3. Create positive emotions - Easy games can bring about positive emotions and uplift ones mood, and help in promoting relaxation.
4. Stimulate learning - Playing video games can help an individual to learn new skills.
Molar mass of LiBr (mm )= 86.845 g/mol
Molarity ( M ) = 4 M
Mass of solute ( m ) = 100 g
Volume ( V ) = in liters ?
V = m / mm * M
V = 100 / 86.845 * 4
V = 100 / 347.38
V = 0.2875 L

Answer:
Waves transfer energy from one place to another without transferring matter. Wave motion (the movement of waves) can be shown by the vibrations of a spring or by water waves.

The density can be calculated using the following rule:
density = mass/volume
therefore,
volume = mass/density
we have the mass=22 mg=0.022 grams and density=0.754g/cm^3
substituting in the above equation, we can calculate the volume as follows:
volume = 0.022/0.754 = 0.0291 cm^3
