Is there a chemical reaction between the water in salt that will allow the egg float?

1 answer:

7 0

No. While the salt added to the water creates a solution with a higher density than the egg it's self which allows it to float, there was no actual chemical reaction. Because both the salt and water can eventually be separated, that makes it a physical change rather than chemical.

Question 23 (3 points)

Mice21 [21]

Answer:

<h2>The answer is 3.0 mL</h2>

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

$volume = \frac{mass}{density} \\$

From the question

mass of aluminum = 8.1 g

density = 2.7 g/mL

It's volume is

$volume = \frac{8.1}{2.7} \\$

We have the final answer as

0.500 mile of potassium oxide is dissolved in enough water to make 2.00 L of solution. Calculate the molarity of this solution (

SCORPION-xisa [38]

The correct question is as follows: 0.500 moles of potassium oxide is dissolved in enough water to make 2.00 L of solution. Calculate the molarity of this solution (plz help!)

Answer: The molarity of this solution is 0.25 M.

Explanation:

Molarity is the number of moles of a substance divided by volume in liter.

As it is given that there are 0.5 moles of potassium oxide in 2.00 L of water so, the molarity of this solution is calculated as follows.

$Molarity = \frac{moles}{volume(in L)}\\= \frac{0.5 moles}{2.00 L}\\= 0.25 M$

Thus, we can conclude that molarity of this solution is 0.25 M.
