What happens when a strip of red litmus is immersed in a beaker containing 10% sodium hydroxide?
fica molhado
What else can I help you with?
What happens if you added soduim hydroxide solution to some hydrochloric acid in a beaker?
When sodium hydroxide solution is added to hydrochloric acid in a beaker, a chemical reaction occurs, resulting in the formation of water and sodium chloride salt. This reaction is exothermic, meaning it releases heat energy. The pH of the resulting solution will increase due to the presence of sodium hydroxide, which is a strong base.
What happens to the concentration of sodium hydroxide solution when it is left in beaker?
If left in an open beaker, the concentration of sodium hydroxide solution may decrease due to evaporation of water. If left in a closed beaker, the concentration should remain constant unless there is some chemical reaction occurring.
What happens when an object is dropped into a beaker containing a liquid and then the object drops to the bottom of the beaker?
The density of the object is at least equal to, and possibly greater than, the density of the liquid in the beaker.
What you use a beaker for in science?
Containing liquids that are possibly harmful.
What would happen if a glowing splint is held at the mouth of a beaker containing a piece of potassium and water And what is the gas evolved?
If a glowing splint is held at the mouth of a beaker containing potassium and water, the potassium will react violently with the water, producing potassium hydroxide and hydrogen gas. The hydrogen gas is highly flammable, and as it is released, it can ignite from the heat of the reaction, resulting in a small explosion or fire. The gas evolved during this reaction is hydrogen.
What laboratory tools are used to containing liquids and substances?
A Flask or Beaker.
What happens when a piece of magnesium is dropped into a beaker of hot water?
The magnesium reacts with the water to produce magnesium hydroxide and hydrogen gas. This reaction is exothermic, meaning it releases heat. The hydrogen gas can be collected and tested by igniting it to see its flammability.
Explain Why a beaker containing sand and water is mixture although sand itself is a pure substance?
Because you mixed sand and water together in the beaker.
Which of the two quantities upthrust or weight will change when an immersed body is slightly raised from the bottom of a beaker with a string?
The upthrust will decrease when an immersed body is slightly raised from the bottom of a beaker with a string, as the body is displacing less fluid and therefore experiencing less buoyant force. The weight of the body remains constant because it depends on the mass of the body, which does not change in this scenario.
What is buognant force?
The force applied by the liquid on the solid immersed in it is called bouyant force .one can experience this force by pushing a cork into a beaker of water.
If a beaker contains glucose and is permeable to glucose what will happen to the glucose?
If a beaker containing glucose is permeable to glucose, then the glucose will go through the beaker.
What happens to the thermal energy in a beaker as it cools down?
As the beaker cools down, the thermal energy within it decreases. This results in a transfer of heat from the beaker to its surroundings, causing the temperature of the beaker to drop.
