Answer:
Molarity is halved when the volume of solvent is doubled.
Explanation:
Using the dilution equation (volume 1)(molarity 1)=(volume 2)(molarity 2), we can demonstrate the effects of doubling volume.
Suppose the starting volume is 1 L and the starting molarity is 1 M, and doubling the volume would make the final volume 2 L.
Plugging these numbers into the equation, we can figure out the final molarity.
(1 L)(1 M)=(2 L)(X M)
X M= (1 L x 1 M)/(2 L)
X M= 1/2 M
This shows that the molarity is halved when the volume of solvent is doubled.
First read the introduction.
Seconds look at the pictures how to build it.
Answer: B:
Explanation:
This is the most reasonable answer
A and d is physical, b and c is chemical
<span>If the the level of water in a container is compared before and after the fusion, it can be realized that the ice has a higher level than that of liquid water: solid and liquid water does not have the same volume.
</span><span>We can generalize:
A state change always causes a change in volume.
Comment:
Water is an exception, volume increases during a melting for most of substances.</span>
