What else can I help you with?
What is it called when a liquid reacts with a solid the temperature dropped and a gas is released?
An endothermic reaction usually exhibits a drop in temperature.
What evidence of a chemical reaction when you drop an Alka-Seltzer tablet into a glass of water?
When an Alka-Seltzer tablet is dropped into water, it undergoes a chemical reaction that produces carbon dioxide gas, as evidenced by the rapid formation of bubbles and fizzing. This reaction occurs as the tablet dissolves, releasing citric acid and sodium bicarbonate, which react to create the gas. Additionally, there may be a slight temperature change in the water, indicating an endothermic reaction. These observable changes confirm that a chemical reaction is taking place.
What happens when a dilute acid is dropped onto carbonates?
When a dilute acid is dropped onto carbonates, a chemical reaction occurs where the acid reacts with the carbonate to produce carbon dioxide gas, water, and a salt. For example, when hydrochloric acid is dropped onto calcium carbonate, the reaction produces carbon dioxide gas, water, and calcium chloride.
What chemically happens when alka seltzer tablets are dropped into water?
When an Alka-Seltzer tablet is dropped into water, the citric acid and sodium bicarbonate in the tablet react to form carbon dioxide gas, which creates bubbles. This reaction is what causes the fizzing and bubbling that you see when the tablet is dropped into water.
How will changing the waters mass affect how much the waters temperature increases when the cylinder is dropped?
Changing the water's mass will affect how much the water's temperature increases when a cylinder is dropped due to the principle of heat capacity. A larger mass of water has a greater capacity to absorb heat, meaning that the temperature increase will be smaller for a given amount of heat transferred from the cylinder. Conversely, a smaller mass of water will experience a greater temperature increase because it has less mass to absorb the same amount of heat. Therefore, the relationship between water mass and temperature change is inversely proportional.
What happens when sodium metal dropped in water write in chemical equation?
2Na(s) + 2H2O ===> 2NaOH + H2(g). What happens is a vigorous reaction, so stand back.
Why does velocity increase immediately after an object is dropped?
A continuous force(Gravitational Pull) is always there, but at a still object, there is a reaction force over it... But when dropping, there is on such force other than the reaction of wind etc so the velocity increases.... But the increasing of velocity also has a maximum limit.... !! Mostly depending on the object and the surrounding....
The temperature dropped from - 2 degrees to - 11 degrees How many degrees was the drop?
-9
What element is easy to shape but when dropped in water it can rust?
Iron. Iron is a malleable metal that is easy to shape, but when exposed to water it can rust due to a chemical reaction with oxygen in the air and moisture.
When a small piece of potassium metal is dropped into a breaker of water the potassium moves about rapidly and then ignites within seconds the metal is gone and all activity ceases this is and example?
It is an example of a chemical reaction
What is product in a chemical reaction?
what substance you get when you're done with the chemical change.ex: match+lighter=reactants. when you mix those a certain way, you get a light!
How does temperature affect the height of a dropped ball?
As temperature increases, air density decreases, resulting in less air resistance on the ball as it falls. This reduced air resistance allows the ball to travel slightly higher before gravity pulls it back down. Conversely, in colder temperatures, higher air density increases air resistance, causing the ball to reach a slightly lower height when dropped.
