Chemical reactions and lightning

Front

What is a chemical reaction?

Back

A process in which substances (reactants) are transformed into different substances (products) through the breaking and forming of chemical bonds.

Front

What is a double replacement reaction?

Back

A type of chemical reaction where two compounds exchange ions or bonds to form two new compounds.

Front

What are the products of the reaction Co₂(SO₄)₃ + NaOH?

Back

Co(OH)₃ + Na₂SO₄.

Front

What is the product of the synthesis reaction Ca + N₂?

Back

Ca₃N₂.

Front

What role does lightning play in atmospheric chemistry?

Back

It facilitates the fixation of atmospheric nitrogen.

Front

What is the general equation for a double replacement reaction?

Back

AB + CD → AD + CB, where A and C are cations and B and D are anions.

Front

What is the significance of balancing chemical equations?

Back

Balancing chemical equations ensures that the law of conservation of mass is obeyed, meaning the number of atoms of each element is the same on both sides of the equation.

Front

What is a synthesis reaction?

Back

A type of chemical reaction where two or more simple substances combine to form a more complex product.

Front

What is the product of the double replacement reaction AgNO₃ + KCl?

Back

AgCl + KNO₃.

Front

What is the difference between a single replacement and a double replacement reaction?

Back

In a single replacement reaction, one element replaces another in a compound, while in a double replacement reaction, two compounds exchange components.
