Answer:
113 kJ or 113,000J
Explanation:
Since we are condensing it, a physical change in the state of matter is occurring. 113 kJ or 113,000J because of the following equation: Q = 2260 times 50. 2260 is the Heat of Vaporization constant.
Answer: A balloon is charged by a process of frictional charging and the object is getting charged by the process of induction.
Explanation:
When two bodies are rubbed against each other, charging by friction or rubbing occurs. The electropositive object loses electrons to electronegative object. Thus, when balloon is rubbed on a wall, it becomes charged.
The charged balloon is able to attract an uncharged object by inducing charge on it without the two objects touching each other. Electrostatic force acts between two charged objects. Charged balloon causes electrons to move at one end thereby inducing opposite charge in the object and thus, charged balloon is able to attract uncharged object.
When two liquids are completely soluble in each other in all proportions, they are said to be miscible<span>. For example, ethanol and water are </span>miscible<span>. If the liquids do not mix, they are said to be </span>immiscible<span>.</span>
Answer:
a strong electrolyte
Explanation:
Let's look at the meaning of the following terms so we can obtain the right answer by means of elimination.
- Strong Electrolyte : A strong electrolyte is a solution/solute that completely, or almost completely, ionizes or dissociates in a solution. These ions are good conductors of electric current in the solution.
- Weak Electrolyte : A weak electrolyte is an electrolyte that does not completely dissociate in aqueous solution. The solution will contain both ions and molecules of the electrolyte. Weak electrolytes only partially ionize in water (usually 1% to 10%)
- Strong ion : Strong ions are cations and anions that exist as charged particles dissociated from their partner ions at physiologic pH. Thus, these ions are “strong” because their ionization state is independent of pH.
Strong Electrolye fits the condition and hence is the correct option.
Answer:
Explanation:
They are the molecules that are formed when four atoms chemically bond together.
