True!! they can be measured without changing chemical identity.
For the second one it is physical
If your using Plato the correct answer is (A. It accepts protons)
Explanation:
#2.
A centigram is 1/100 of a gram, so that means a gram equals 100 centigrams.
Therefore you multiply 72.4 grams by 100/1 (or just 100), and get 7240 cg.
You did that one right but put the wrong unit in the answer. It is is cg ( centigrams).
#3.
1 liter is equal to 1000 milliliters, and I kiloliter is equal to 1000 liters. So one kiloliter is 1000*1000 milliliters or 1,000,000 milliliters.
The conversion factor would be
1/1000000
#4.
1 gigabyte is equal to 10^9 bytes.
I byte is equal to 10^9 bytes.
So 1 gigabyte is 10^9 * 10^9 nanobytes, or 10^18.
The conversion factor would be (1*10^18)/1.
CH₃CH₂OCH₂ is more soluble in water because it has shorter hydrocarbon chain.
<h3>What is hydrocarbon?</h3>
Hydrocarbon is defined as the compound which contain hydrocarbon and carbon atoms.
The carbon atom attached to each other to form framework and hydrogen atom attach to them in different ways to give different configuration. One of the most popular hydrocarbon compound is diamond.
<h3>Solubility of hydrocarbon in water</h3>
Hydrocarbon is non polar compound whereas water is polar compound. So, hydrocarbon is in soluble in water. But as they have weak intermolecular interactions known as London dispersion forces i.e. Instantaneous dipole-induced dipole interactions.
make them less soluble in water.
Greater the hydrocarbon chain lesser will be the solubility of ketone in water. On the other hand, lesser the hydrocarbon chain greater will be the solubility of ketone in water.
Thus, we concluded that the CH₃CH₂OCH₂ is more soluble in water because it has shorter hydrocarbon chain.
