The answer is dissolved salts
Explanation:
Mole ratio of Zn to HCl = 1 : 2.
If we use all 2.0mol of Zn, we would need 2.0 * 2 = 4.0mol of HCl. However we only have 3.0mol of HCl.
Therefore HCl is limiting.
By convention, the symbol Z is assigned to the number of protons in the nucleus, or simply, the atomic number of an element. This is actually used when you want to determine the effective nuclear charge of a specific electron of an element. The equation is:
Z* = Z - S
where
Z* is the effective nuclear charge
Z is the atomic number
S is the number of electrons between the electron in question and the nucleus
There is due to a phenomenon called the shielding effect. This effect states that the farther the electron is from the nucleus, the lesser is its pull of force to the nucleus. That is the reason why the valence electrons (outermost electrons) are the ones always involved in chemicals reactions. Because they are not that strongly bonded to the nucleus of an atom.
Answer:
D
Explanation:
Sparking can be caused by defective cooktop elements, loose connectors, a wire with frayed insulation or a broken wire arcing over to the appliance metal frame, says Appliance Repair. If the cause of the sparking is a broken wire or a wire with frayed insulation, do not attempt to splice the wire; you must replace it. Repair Clinic suggests checking the spark ignition switches, as they might be defective and in need of replacing.
