What else can I help you with?
What things can be done to change how fast a chemical reaction occurs?
You can add a catalyst, or raise the temperature, or change the pressure, these are some of the things done to speed up a chemical reaction.
What kind of reaction is photosynthesis?
Photosynthesis is a chemical reaction that converts carbon dioxide and water into glucose and oxygen using sunlight as an energy source. It is a complex process that occurs in plants, algae, and some bacteria.
Different ways that pure metals are recovered from the ore?
depends on which metal, and which ore. Most are crushed- then some are roasted (heated) some are separated by weight, physical characteristics, etc. In some cases, metals are recovered by chemical reaction, using a chemical that dissolves the metal, which removes it from the waste material.
Can a chemical change be undone?
Some chemical changes are reversible, others are not.
What are some common reaction?
Metals rusting, wood or fuel burning, yeast fermenting sugar, and cellular respiration are common chemical reactions.
What chemical reaction occurs when an airbag is inflated?
When an airbag is inflated, a chemical reaction involving the rapid decomposition of sodium azide (NaN3) occurs. This reaction produces nitrogen gas (N2) which rapidly fills the airbag, causing it to inflate quickly to protect the occupants of the vehicle in the event of a collision.
What are amphoteric metals?
Amphoteric is a chemical entity (ion or molecule) which can react as an acid but also as a base. Compounds of beryllium, tin, aluminium, lead, zinc have amphoteric hydroxides and oxides.
Explain why the reaction of an acid with some metals can be dangerous?
The reaction of an acid with some metals can be dangerous because it produces flammable hydrogen gas. If the reaction occurs in a closed environment, the build-up of hydrogen gas can lead to an explosion. Additionally, the release of toxic fumes during the reaction can pose health hazards.
Reacts with certain metals acid or base?
When certain metals come into contact with acids, they undergo a chemical reaction where hydrogen gas is produced. With bases, some metals may react to form hydrogen gas and a metal salt. The reactivity of the metal and the type of acid or base will determine the specific reaction that takes place.
Which chemical family contains multivalent metals?
Some of the transition state metals are multivalent.
What are some differences between physical and chemical properties?
A chemical property is when you mix two substances together and a change occurs, a chemical reaction. A physical property is when you literally do something to it, like burning paper, braking wood with an axe, etc.
Does a chemical change make a new substance?
some chemical reaction can.
