The three products of cellular respiration are carbon dioxide (CO2), water (H2O), and energy (usually in the form of ATP).
An independent variable is something that will occur without something else happening. An example of an independent variable is when your income depends on the number of sales. In this situation, your income depends on how many sales you make, so therefore, the number of sales you make is the independent variable.
Rock cycle - a process in which a rock forms, changes from one type of rock to another, forms again by processes on and in the Earth.
Metamorphic Rock - Rocks changed by intense heat or extreme pressure.
Sedimentary Rock - A rock that forms when sediments are compacted and cemented together.
Igneous Rock - A rock that forms when molten rock cools and hardens.
The answer is; C
Conservation of matter in a reaction means that the mass of matter in the products is equal to the mass of the reactants. Energy/matter cannot be created or destroyed but converted from one form to another.
An expanding balloon with the increased evolution of gas is a good visible practical sign in the experiment on the conservation of matter in the reaction. As the magnesium disappears with an increased input of hydrochloric acid, the balloon gets bigger showing that more hydrogen is evolved from the reaction;
2HCL + Mg MgCl2 + H2
A cation is an atom or group of atoms that have a positive charge.
