Magnetic energy from the magnet applies a force to the compass needle causing it to move
Answer:
They are directly proportional
Explanation:
when the kelvin temperature increases, the average kinetic energy of particles increases and they move faster and vice versa.
The two salts would be <span>Silver Iodide & Silver Bromide</span>
Answer: 19 grams
Explanation:
percent by mass = (mass of part)/(mass of whole) * 100
this means that in this question, 12 = x/160 * 100, where x is the amount of NaCl.
this means 12/100 = x/160, and thus x = (160)(12/100)=19.2 grams
The closest option is B.
Answer:
How would you confirm that a colourless liquid given to you is pure water? A very easy solution is to take a sample of the colourless liquid and put it on the stove if it starts boiling exactly at 100 ºC then it is pure water. Any other colourless liquid such as vinegar always has a different boiling point.
