Answer:

Part A: (on left side)

Hydrogen= 511
Carbon=7
Oxygen= 3
Sodium= 1

Part B: (on the right side)

Hydrogen= 511
Carbon=7
Oxygen= 3
Sodium= 1

Here is the thing, for a chemical equation, both sides have same number of atoms, even though the compounds are different

b. 80.06 g/mol

c. 133.33 g/mol

General Formulas and Concepts:

Chemistry - Atomic Structure

Reading a Periodic Table
Molar Mass - 1 mol per x grams substance

Explanation:

Step 1: Define

a. NH₄Cl

b. NH₄NO₃

c. AlCl₃

Step 2: Find masses

Molar Mass of N - 14.01 g/mol

Molar Mass of H - 1.01 g/mol

Molar Mass of O - 16.00 g/mol

Molar Mass of Al - 26.98 g/mol

Molar Mass of Cl - 35.45 g/mol

Step 3: Calculate compound masses

Molar Mass of NH₄Cl - 14.01 g/mol + 4(1.01 g/mol) + 35.45 g/mol = 53.5 g/mol

Molar Mass of NH₄NO₃ - 2(14.01 g/mol) + 4(1.01 g/mol) + 3(16.00 g/mol) = 80.06 g/mol

Molar Mass of AlCl₃ - 26.98 g/mol + 3(35.45 g/mol) = 133.33 g/mol

What happens to the potential energy of an object when it falling from a high place?

Juliette [100K]

Answer:

The higher up an object is the greater its gravitational potential energy. ... As most of this GPE gets changed into kinetic energy, the higher up the object starts from the faster it will be falling when it hits the ground. So a change in gravitational potential energy depends on the height an object moves through.
