Answer:
In a chemical reaction, there is a change in the composition of the substances in question; in a physical change there is a difference in the appearance, smell, or simple display of a sample of matter without a change in composition. Although we call them physical "reactions," no reaction is actually occurring.
To make a supersaturated solution<span>, make a saturated </span>solution<span> of sugar by adding 360 grams of sugar to 100 mL of water at 80 degrees Celsius. When the water cools back down to 25 degrees, that 360 grams of sugar will still be dissolved even though the water </span>should<span> only dissolve 210 grams of sugar.</span>
Cadium
Down a period, atomic radii decrease from left to right due to the increase in the number of protons and electrons across a period.
A base and an Acid always react to form a salt and water
So, HCl + NaOH —> NaCl + HOH
Answer:
Explanation:
Hello,
In this case, the first step is to compute the difference in the electronegativity for the formed bond between gallium and phosphorous by:
Thus, we can compute the percentage of ionic character by:
So the fraction is just:
Which has sense since gallium phosphide is a non-polar compound.
Regards.
