What happened to the hot water with food coloring as it drops in the cold water Brainly?
The food coloring you add to the water is pushed around by the water molecules. Since the molecules in warm water move around faster, the food coloring spreads out quicker in the warm water than in the cold water.
Why do things react faster in hot water?
When water is heated, the molecules gain energy and, thus, move faster. As they move faster, they come into contact with the sugar more often, causing it to dissolve faster.
Does be react with hot water?
Beryllium (Be) is the only alkaline earth metal that does not react with water or steam, even if metal is heated to red heat. Additionally, beryllium has a resistant outer oxide layer that lowers its reactivity at lower temperatures.
Is cold water or hot water more reactive?
You’re misreading the activity series chart. The most active metals will react with cold water, hot water, steam and acid. As you move to lower reactivity, reaction with cold water goes away, then hot water, then steam, then acid.
Does CA react with hot water?
The reaction of calcium with water is less violent. The heat evolved is not sufficient for the hydrogen to catch fire. Calcium starts floating because the bubbles of hydrogen gas formed stick to the surface of the metal. Magnesium does not react with cold water.
What reacts with water?
Water reactive chemicals are chemicals that react vigorously with moisture. The most common water sensitive chemicals include sodium, potassium, lithium metals and aluminum alkyls.
Which glow stick will be brighter once it is bent?
Which glow stick will be brighter once it is bent? Explain your answer. The glow stick that was in the cup of hot water will be brighter once it is bent. The production of more light is evidence that the chemical reaction in the glow stick is happening faster.
What happens if you microwave a glow stick?
Microwaves excite the hydrogen peroxide in the glow sticks and make the glow sticks react faster (brighter). They will still last for hours though when they start to die, they die for good. DON”T DO IT FOR MORE THAN 10 Seconds.
Can you touch the liquid inside of a glow stick?
The contents can irritate the skin, eyes and mouth, the experts warn. Some glow products contain a chemical called dibutyl phthalate (DBP). If the liquid gets on the skin, wash it off immediately to prevent the child from rubbing the chemical in the eyes. If it gets in the eyes, it will cause redness and burning.
How long does a glow stick last?
Typically, the smaller the glow stick, the shorter the glow duration due to the amount of chemical glow used inside the glow stick. Industrial Quality 6 Inch Glow Sticks can last up to 12 hours and Long Lasting Glow Sticks that use a special powder based formula can glow for over 24 hours.
