Answer:
3.23 atm
Explanation:
Use the equation P₁V₁=P₂V₂. P₁ and V₁ are initial pressure and volume. P₂ and V₂ are final pressure and volume. Solve for P₂.
(1.88 L)(3.81 atm) = (2.22 L)(P₂)
7.1628 L*atm = (2.22 L)(P₂)
P₂ = 3.226 atm
Answer:
124 g (3 sig figs)
or
124.011 g (6 sig figs
Explanation:
Step 1: Calculate g/mol for AgNO₃
Ag - 107.868 g/mol
N - 14.01 g/mol
O - 16.00 g/mol
107.868 + 14.01 + 16.00(3) = 169.878 g/mol
Step 2: Multiply 0.73 moles by molar mass
0.73 mol (169.979 g/mol)
124 grams of AgNO₃
Answer:
A metal cooking pot
(Many cooking pots are made up of alloys which are combinations of more than one metal)
Answer:
If you mix equal amounts of a strong acid and a strong base, the two chemicals essentially cancel each other out and produce a salt and water. Mixing equal amounts of a strong acid with a strong base also produces a neutral pH (pH = 7) solution.
Answer: there is a buildup of cold water of the west coast of South America.
