How is stoichiometry used

Stoichiometry is used to find the molar ratios between the reactants of a chemical reaction.

How is stoichiometry used to calculate amount of product from amount of reactant

The coefficients give the ratio of moles reactant to moles product.

How are models affected by new evidence

Models are changed if they don't fit new data.

How do atoms show both unity and diversity

There are relatively few atoms, but they make many molecules.

How would you make a 2 M solution of a compound

By dissolving 2.0 moles of the compound in water and then, after complete dissolution, fill it up to a total volume 1.0 L with water.

Which element is the reducing agent in a redox reaction

The reactant that has the atom that gets oxidized

How many ounces is 68 g

2.4 oz

Which of the following best describes a galvanic cell

A battery containing a spontaneous redox reaction

Similar scientific themes are seen in what areas of science

In all areas of science

Which the following is a necessary product of a combustion reaction

heat

In which step of the four stroke engine cycle does the heat from the combustion reaction cause the pistons to move

combustion and expansion

Hydrogen-powered cars create less pollution than gasoline-powered cars when driven. What might be a challenge to using hydrogen as a fuel

Challenges to hydrogen as fuel include no distribution network, ie gas stations, and fear that the car co u l d explode like the Hindenburg.

In the reaction mgcl2 plus 2koh mgoh2 mgoh2 plus 2kcl if 3 moles mgcl2 are added to 4 moles koh what determined how much mgoh2 is made

The amount of Koh

In the reaction MgCl2 plus 2KOH and 65532 Mg(OH)2 plus 2KCl how many moles of KOH react with 1 mole of MgCl2

From the balanced equation it can be seen that it takes 2 moles KOH to react with each 1 mole of MgCl2. So, the answer is 2.
