IONIC OCCURS BETWEEN METALS AND NON METALS
Answer:
false should be the correct response.
the coefficients are equal is NOT a sign that a double displacement reaction has occurred
<u>Explanation:</u>
Usually during solutions of two ionic compounds are combined a precipitate (solid) is created. The mix may become cloudy, or may also separate, with the solids falling at the seat of the receptacle. Infrequently, the mix may bubble as a gas or water is produced.
A precipitation reaction is at two aqueous ionic compounds that make a unique ionic compound that is not soluble in water. The insoluble product compound is called the precipitate. The reaction, in this case, is not balanced, which are evaluated by summing coefficients.
B. chemical bonds, the lines stand for the bond between the compounds.
Answer:
R = 12 ohms
Explanation:
It is given that,
Supply voltage is 12 V
Current in the circuit is 1 A
We need to find the resistance of the circuit. Ohm's law gives the relationship between current, voltage and resistance as follows :
V = IR

So, the resistance of the circuit R is 12 ohms.
