1.12 miles of MgCl2 will be produced from the 32.0 of Mg(OH)2
Answer: As altitude rises, air pressure drops.
Explanation: As altitude increases, the amount of gas molecules in the air decreases—the air becomes less dense than air nearer to sea level.
Answer:
The correct option is: provide a source of counterions to prevent the build-up of charge at both the cathode to the anode.
Explanation:
A salt bridge is a U-shaped glass tube that is used in a voltaic cell or galvanic cell to connect the oxidation and reduction half-cells and complete the electric circuit.
<em>It allows the ions to pass through it, thus preventing the accumulation of charge on the anode and cathode as the chemical reaction proceeds.</em>
<u />
Therefore, the correct option is: <u>provide a source of counterions to prevent the build-up of charge at both the cathode to the anode.</u>
Answer: Option (3) is the correct answer.
Explanation:
When a linear chain of carbon and hydrogen atoms is attached by single bonds only then it is known as alkane.
When a linear chain of carbon and hydrogen atoms contains a double bond then it is known as alkene.
When a linear chain of carbon and hydrogen atoms contains a triple bond then it is known as alkyne.
Therefore, in the given description there is a double bond between third and fourth carbon. Hence, the IUPAC name of given compound is 3-heptene.
A solid that has a high to very high melting point, great hardness, and poor electrical conduction is an : E. Ionic solid
Ionic solid consist of oppositely charge ions. One of the example of Ionic solid is salt (NaCl)
