Answer:
copper
Explanation:
These are usually copper wires with no insulation. They make the path through which the electricity flows. One piece of the wire connects the current from the power source (cell) to the load
Answer:
65,000 g/mol, 43,000g/mol and 22,000 g/mol.
Explanation:
The explanation can be found in the attachment
The choices for this question are N2, O2 and H2O. I believe the closest correct answer would be N2. H2O would have the strongest one as it is capable of hydrogen bonding which is one strong intermolecular force. To compare oxygen and nitrogen, we look at properties of both substances. Oxygen would have a higher boiling point than nitrogen which means oxygen would require more energy to allow phase transition so it should have a stronger force than nitrogen. Thus, nitrogen would have the weakest intermolecular force.
Answer:
Benzoic acid
Explanation:
In this case we have a Grignard reaction in which we go from a formula of C6H5Br to C7H6O2. In other words, we add 1 carbon to the molecule. The only way to add one carbon to this molecule is using as a reagent. When this compound is used as electrophile a carboxylic acid is produced.
Respect to the NMR info, we have a <u>downfield singlet signal</u> at 12.1 ppm which is characteristic of the <u>acid hydrogens</u> in the carboxylic acids (see figure 1). When a carboxylic group is added to the benzene we will obtain the <u>benzoic acid</u> which fits with the formula and the NMR info given.
