Answer:
AuCl
Explanation:
Given parameters:
Mass of Gold = 2.6444g
Mass of Chlorine = 0.476g
Unknown:
Empirical formula = ?
Solution:
Empirical formula is the simplest formula of a compound. Here is the way of determining this formula.
Elements Au Cl
Mass 2.6444 0.476
Molar mass 197 35.5
Number of moles 2.6444/197 0.476/35.5
0.013 0.013
Divide by the
smallest 0.013/0.013 0.013/0.013
1 1
The empirical formula of the compound is AuCl
Answer:
C
Explanation:
The ball is undergoing a gravitational potential to kinetic energy transformation. When the ball is at the top of the slope, it has the potential to be moved down by gravity, hence the name. When it's rolling down the slope, it turns to kinetic energy, which is when something moves.
Hello!
The pressure of an 18 L container which holds 16,00 grams of oxygen gas (O₂) at 45 °C is
0,725 atmTo solve this problem we first need to set up the data in the appropriate units to input it in the
Ideal Gas Law.
a) 16 g of Oxygen gas to moles of oxygen gas:
b) 45 °C to K
Now, we clear the Ideal Gas Equation for P, and solve it:
