Answer:
A: element B
B: element A
C: element B
D: element A
Explanation:
decrease in size leads increase in electronegativity because the smaller the size, the closer the shell is to the nucleus. Also, atomic radius decreases to the right and up on the periodic table. Atomic radius increases to the left and down a period. I hope this helps!
acidic salt is made up of strong acid and weak base whereas normal salt is made up of strong acid and strong base or weak acid and weak base. acidic salt ionises into form H+ions more than OH- ions in water solution but normal salt ionises to form equal number if H+ ions and OH- ions in water solution.
Answer:
A compound
Explanation:
The water is best classified as a compound. When a substance is broken down into elemental composition or units, they are said to be a compound.
- An element is a distinct substance that cannot be split up into simpler substances.
- Compound are substances composed of two or more kinds of atoms joined together in a definite grouping.
- The properties of compounds are distinct and different from those of the individual elements that are combined in its make - up.
- So, the water when broken down to elements is a compound.
Here is your answer:
Remember that potential energy is the energy a object has when it's NOT moving, and kinetic energy is when a object has energy when it IS moving. So examples of this kid of transformation would be kicking a soccer ball at first the soccer ball has potential energy because it's not moving but it has potential to move then when someone kicks the soccer ball it has kinetic energy because the ball is not moving.
Example one: when the video first begin "the ball had potential energy and when the ball swung and hit it that potential energy turned into kinetic energy."
Example two: As the video moves on and the two pillars crashed down it caused another ball to move, at first the "ball had potential energy because it was not moving then when the ramp went down it caused the ball to gain kinetic energy."
Example three: At the end of the video the ball push down a row of wooden blocks then lead to it hitting a "bowling ball across the finish line even though the ball moved slowly and not far it still came from potential energy into kinetic energy."
Hope this helps!
Answer:
B
Explanation:
Chemistry is the study of matter, its composition and the changes it undergoes.
