The answer is B milliliter
Answer:
True: Sodium Chloride Solution will conduct Electricity.
Explanation:
When Sodium Chloride is in solid form it fails to conduct current, But when it is dissolved in water it dissociates to produce a Na⁺ and Cl⁻ ions which are current conducting between two electrodes.
NaCl ₍s₎ + H₂O → Na⁺ ₍aq₎ + Cl⁻₍aq₎
Answer:
Filtration method
Explanation:
Filtration is a separation method used to separate out pure substances in mixtures comprised of particles some of which are large enough in size to be captured with a porous material. Particle size can vary considerably, given the type of mixture. For instance, a mixture of boiled pasta and water.
Explanation:
The number of vacancies per cubic meter are calculated as follows.
= 
Putting the given values into the above formula as follows.
= 
= 
= 
= 4.706 
Thus, we can conclude that number of vacancies per cubic meter for some metal, M, is 4.706 .
Hi!
Magnets attract with opposite poles. The reason is the North pole of a magnet's magnetic lines (if that makes any sense) generally flow inwards, making it pulling in, and the South pole's magnetic lines flow outwards, pushing out. If you align two magnets with the same poles together, they will always repel, because they will be flowing in different directions.
However, if you align a north and a south pole together, they will work together, and attract.
Therefore, if you place two magnets randomly, and they're close enough, they'll align so that the north pole of one magnet faces the south pole of the other magnet, or choice A.
