Answer:
Any material that exerts magnetic force is considered a magnet.
The given statement is True.
Explanation:
Material that exerts magnetic force is a magnet.
- Whatever material exerts magnetic force, that is supposed to call a magnet.
- Alike all distinct forces, a magnetic force implies a gravitational force.
- The area within the poles of a magnet has the most powerful effect and the magnets attract wood and materials that contain iron.

Answer:
5.46 M
Explanation:
First, we need to know the molar mass of the citric acid, the molar masses of the elements are:
H = 1 g/mol
C = 12 g/mol
O = 16 g/mol
So the molar mass of the acid is: 8x1 + 6x12 + 7x16 = 192 g/mol
The mass of the acid is the number of moles multiplied by the molar mass, so:
m = 0.688x192 = 132.096 g
Then, the volume is the mass divided by the concentration:
V = 132.096/1.049 = 125.926 mL = 0.1259 L
So, the molar concentration is the number of moles divided by the volume in liters:
M = 0.688/0.1259
M = 5.46 M
The balanced reaction between Zn and HCl is as follows:
Zn(s) + 2HCl(aq) -> ZnCl2(aq) + H2(g)
This means that HCl would be the limiting reactant.
