2. If you add water to dilute a solution, what happens to the molarity of the compound in the

1 answer:

4 0

Each solution has a molaritu, which is equal to the number of moles of a solvent per liter of solutions. When you add water to a solution, the number of moles of the solvent stays the same while the volume increases. Therefore, the molarity decreases; the solution is diluted.

2 C2H2 + 5 O2 2 H2O + 4 CO2 what reaction type

Alexxx [7]

Answer:

Combustion reaction

General Formulas and Concepts:

Chemistry

Synthesis Reactions: A + B → AB

Decomposition Reactions: AB → A + B

Single-Replacement Reactions: A + BC → AB + C

Double-Replacement Reactions: AB + CD → AD + BC

Explanation:

Step 1: Define

2C₂H₂ + 5O₂ → 2H₂O + 4CO₂

Step 2: Identify

Any organic molecule reacting with oxygen to produce water and carbon dioxide is a combustion reaction.

We also see from the RxN that is is a double replacement reaction.

Which sample contains the greatest number of atoms? which sample contains the greatest number of atoms? 14 gc 102 gag 49 gcr 202

Mashcka [7]

The answer to this question would be: 14g of Carbon
In this question, you are given the weight of the element. Then, to find the number of atoms you need to divide the weight with the molecular mass of the each element.

14 g c /(12 g/mole)= 1.167 mole
102 g ag /(107 g/mole)= 0.95 mole
49 g cr /(52 g/mole)= 0.94 mole
202 g pb /(207 g/mole)= 0.975 mole
