Is cutting up a pear a chemical reaction?
No it isn't, however, the oxidation of the organic material that occurs after the Pear has been cut, is a chemical reaction, it is called Redox.
Why is the total mass of the products of a chemical reaction is equal to the total mas of the reactants?
This isn't true. The mass of reactants will equal mass of products in a closed system where gasses cannot enter or escape, but the mass can decrease if a gas is formed that escapes into the atmosphere (for example, hydrogen from your reactants is transformed into hydrogen or oxygen gas which escape into the room) or even INCREASE of the reaction draws in gas from the atmosphere which is incorporated into the product. There might even be an increase in mass if water vapor from the air ends up entering into the reaction. The equation for the reaction will always balance because of conservation of mass, but where that mass ends up can mean that the final weights to NOT remain the same. A closed system doesn't allow for entry or exit of additional mass, but an open system might.
Which layer makes up 2-3 of the earth's mass?
The layer of earth that makes up about two-thirds of earths mass is the inner-mantle..
Which compositional zone of earth makes up almost two thirds of the planet's mass?
The Mantle makes up almost two-thirds of the planet's mass.
What speeds up rates of chemical reaction and weathering in rocks and soils?
== == Heat and water.
Does vinegar and baking soda create a big chemical reaction?
it makes a chemical reaction but not a big one. it just bubbles up and then stops.
What states that the mass of what you end up with after a chemical reaction is the same you start with?
Physical property
What does the law of conservation of mass state that cannot be created or destroyed during a chemical reaction?
The law of conservation of mass (or matter) states that mass (or matter) cannot be created or destroyed during a chemical reaction. *Matter is anything that has mass and takes up space, so a lot of scientists call this the law of conservation of matter.
Is a catalyst a compound that makes up a living organism?
A catalyst is something that speeds up a chemical reaction
What can a chemical reaction be speeded up by?
A catalyst can speed up a chemical reaction.
What can speed up a chemical reaction by decreasing?
chemical reaction
What is chemical reaction in an enzyme?
to speed up a chemical reaction
What is lavoisier's law of conservation of metter?
Antoine Lavoisier's Law of Conservation of Matter states that the total mass of the products of a chemical reaction is always the same as the total mass of the starting materials used up in the reaction.
What is lowered to speed up a chemical reaction?
Activation energy is lowered to speed up a chemical reaction.
What function catalyst perform in chemical reaction?
Catalysts speed up the chemical reaction.
What makes chemical reaction to go faster?
cofee or nos or an energy drink would speed up a chemical reaction..
What is a chemical reaction that happens when a hot air balloon flies?
A chemical reaction in a hot air balloon can be when the propane is heated up. That is a chemical reaction because something has heated up.
