What type of substance will react exothermically wit oxygen?
Hydrogen will, thus forming water. But there are probably more substances
What will you observe when burning calcium induced in a jar of oxygen?
It burns with a brick red flame and a white ash of calcium oxide reacts exothermically with water to form basic calcium hydroxide.
How is calcium chloride bad for the environment?
Calcium chloride can act as an irritant by desiccating moist skin. Solid calcium chloride dissolves exothermically, and burns can result in the mouth and esophagus if it is ingested. Ingestion of concentrated solutions or solid products may cause gastrointestinal irritation or ulceration
What happens if you mix hydogen with air?
Hydrogen is already a element in the air. So in other words, nothing will happen. +++ That is Not Correct on both counts. Think about it: hydrogen is extremely flammable. Hydrogen is an element, yes, but not a component of the atmosphere, except perhaps in vanishingly tiny quantities. Besides, the question posits a deliberate mixing. Hydrogen burns in air, i.e. combines exothermically with oxygen that IS in the atmosphere, producing water.
What would happen if a sodium atom and a chlorine atom came into contact?
They combine to make sodium chloride, commonly known as table salt.
Which compound forms exothermically?
An example of a compound that forms exothermically is hydrogen fluoride. It can exist as a colorless gas or as a fuming liquid, and can also be dissolved in water.
What will happen to aluminum foil if soaked on Cupric Chloride?
It exothermically reacts and dissolves
What type of substance will react exothermically wit oxygen?
Hydrogen will, thus forming water. But there are probably more substances
Why is calcium oxide described as a base?
It reacts with acids, it dissolves exothermically in water to produce a basic solution.
What type of energy does a fire use?
Chemical potential energy. Fire is a chemical reaction caused by heat Fuel and oxygen (usually) The fuel is combusted exothermically (ie giving off heat) with oxygen which is a chemical reaction. This causes surrounding fuel to heat up a react exothermically with the oxygen, propagating the fire.
What will you observe when burning calcium induced in a jar of oxygen?
It burns with a brick red flame and a white ash of calcium oxide reacts exothermically with water to form basic calcium hydroxide.
Does sugar decrease the temperature of hot boiling water?
yes. sugar doesn't react exothermically with water (it doesn't give out heat when you put it in water). It will usually absorb some of the heat from the water for thermal equilibrium to occur.
Disadvantages of fluorine?
Fluorine is extremely reactive. It will react with many substances at room temperature and can spontaneously set fire to organic material. It will react exothermically with substances normally used to extinguish fires such as water and carbon dioxide. When it reacts it can form toxic compounds such as hydrogen fluoride.
How is calcium chloride bad for the environment?
Calcium chloride can act as an irritant by desiccating moist skin. Solid calcium chloride dissolves exothermically, and burns can result in the mouth and esophagus if it is ingested. Ingestion of concentrated solutions or solid products may cause gastrointestinal irritation or ulceration
Which chemical is called plaster pf paries?
CaSO4 1/2 H2O. Calcium sulfate hemihydrate. This reacts exothermically, i.e gives off heat, when it reacts with water to form CaSO4 2 H2O, Calcium sulfate dihyrate also known as gypum, a white solid.
Why are fireworks so loud I love fireworks but why are they so loud?
Fireworks are made of chemicals that, when heated, react violently and exothermically (i.e. produce more heat than is put into initiating the reaction), and there's a lot of extra heat. This sudden burst of heat causes the air to move rapidly, producing a short, loud burst.
What dissolves exothermically?
Dissolution overall can be either endothermic or exothermic, depending on whether more energy was used to break the bonds, or more energy was released when new bonds were formed. If more energy is released in making bonds than is used in breaking bonds, the process is exothermic. If more energy is used than is released, the process is endothermic.
