1. Solid
2. Have crystalline structure
3. Naturally occurring
4. Inorganic
5. Has defined homogeneous chemical composition
Thermal energy is defined as the total kinetic energy of all particles in an object. Even though the cup of water has a higher temperature, the bathtub has more thermal energy because it contains much more mass of water compared to the cup.
Answer:
The answer is <u>C. As2O3</u>
Explanation:
0.600 gr of Arsenic and Oxygen.
0.454 gr of Arsenic
So, 0.146 gr of Oxygen will be in the compound.
- First: The grams of each element must be divided by its atomic weight:
- 0.454 gr As / 74.92u As = 0.00606
- 0.146 gr O / 16u O = 0.009125
- Both results must be divided by the lowest number found:
- 0.009125 / 0.00606 = 1.5 O
- As one of the values is not an integer then both results are multiplied until both give an integer:
- Then the answer is given:
Answer:
FeCl₃
Explanation:
4FeCl₃ + 3O₂ => 2Fe₂O₃+ 6Cl₂
Given => 7moles 9moles
A simple way to determine which reagent is the limiting reactant is to convert all given data to moles then divide by the respective coefficients of the balanced equation. The smaller value will be the limiting reactant.
4FeCl₃ + 3O₂ => 2Fe₂O₃+ 6Cl₂
Given => 7/4 = 1.75* 9/3 = 3
*Smaller value => FeCl₃ is limiting reactant.
NOTE: However, when working problems, one must use original mole values given.
