Answer:
A little boy is playing with a plastic water bottle. He blows air into the bottle to make a whistling sound. Then, he wedges a plastic ball into the bottle to make a rattle. But the ball is too big—it gets stuck in the mouth of the bottle! The little boy panics and runs to his big brother for help.
Luckily, his older brother just studied the principle of Boyle's law. Based on what he learned, how will he get the ball out of the bottle?
by placing the bottle in the freezer to decrease the mass of the air inside the bottle
by pushing down on the bottle to decrease the temperature of the air in the bottle
by placing the bottle in the freezer to increase the air pressure inside the bottle
by pushing down on the bottle to increase the air pressure inside the bottle?
Explanation:
You will need to heat the bottom of the bottle to make gas build up than the ball will pop out.
The crust is the outside layer and also the thinnest.
Answer:
The same number of proteins in their nucleus.
Answer:
0.147 mol
Explanation:
Step 1: Calculate the volumetric concentration (Cv)
We will use the following expression.
Cv = Cg × ρ
Cv = 98.0 g%g × 1.84 g/mL = 180 g%mL
Step 2: Calculate the molarity of sulfuric acid
We will use the following expression.
M = mass solute / molar mass solute × liters of solution
M = 180 g / 98.08 g/mol × 0.100 L = 18.4 M
Step 3: Calculate the moles of solute in 8.00 mL of solution
8.00 × 10⁻³ L × 18.4 mol/L = 0.147 mol
