Answer:
Explanation:
Hello,
In this case, the undergone chemical reaction is:
In such a way, the acidic redox balance turns out:
Which leads to the total balanced equation as follows:
Thus, as the mass of oxalic acid is not given, one could suppose a value of 1 g (which you can modify based on the actual statement) in order to compute the oxalic acid moles as shwon below:
Whereby the molality results:
Remember you can modify the oxalic acid mass as you desire.
Best regards.
Answer:
The correct answer is B) both are made up of monomers that are linked by covalent bonds
Explanation:
The polymers consist of a set of monomers by covalent bonds. There are those that are natural (DNA formed by nucleotide units, proteins by amino acids, starch by glucose) and synthetics made by human hands (polyethylene formed by ethylene monomers).
Answer:
Elements in the same group in a periodic table have similar chemical properties.
A. Variables, this is because you can choose what you're testing
Answer:
There are two chloride ions for each calcium ion
Explanation:
The compound has to have an overall neutral charge. Meaning that the positive charges from calcium have to be canceled out by the negative charges of chlorine.
If there are two chloride ions for each calcium ion, the charges would cancel themselves out (2 * -1 would cancel out with +2).
