predicting products of chemical reactions

Front

What is a double replacement (DR) reaction?

Back

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

Front

How do you balance a chemical equation?

Back

To balance a chemical equation, ensure that the number of atoms of each element is the same on both sides of the equation by adjusting coefficients.

Front

What is the general form of a combustion reaction?

Back

The general form of a combustion reaction is: fuel + oxygen → water + carbon dioxide.

Front

What is a single replacement (SR) reaction?

Back

A single replacement reaction is a type of chemical reaction where one element replaces another element in a compound.

Front

What is the product of the reaction between magnesium (Mg) and copper(II) chloride (CuCl2)?

Back

The products are magnesium chloride (MgCl2) and copper (Cu).

Front

What is the product of the reaction between zinc (Zn) and sulfuric acid (H2SO4)?

Back

The products are zinc sulfate (ZnSO4) and hydrogen gas (H2).

Front

What does NR stand for in chemical reactions?

Back

NR stands for 'No Reaction', indicating that no chemical change occurs.

Front

What is the role of a catalyst in a chemical reaction?

Back

A catalyst speeds up a chemical reaction without being consumed in the process.

Front

What is the significance of the law of conservation of mass in chemical reactions?

Back

The law of conservation of mass states that mass is neither created nor destroyed in a chemical reaction; the total mass of reactants equals the total mass of products.

Front

What is an ionic compound?

Back

An ionic compound is formed when atoms transfer electrons, resulting in the formation of positively and negatively charged ions.
