...."heavier". *The definition of radioactive decay shall do its explanation.
Answer:
A and E.
Explanation:
When water evaporates, it leaves the salt. When rain falls, the salt is diluted. The sun causes the evaporation. The also the sunlight is the energy source, the greatest force propelling the water cycle is gravity. Gravity is the force of attraction between two objects, and Earth’s gravity pulls matter downward, toward its center. It pulls precipitation down from clouds and pulls water downhill. Gravity also moves air and ocean water. Also Water travels in a continuous path through Earth called the water cycle. The journey starts in the Earth's oceans. As the Sun heats the ocean, the water evaporates into a gas. The gas meets cooler air, and the gas changes into droplets of tiny water molecules. This process is called condensation. Little droplets of water fall back down to Earth again as precipitation. The precipitation fills up the rivers and various other things and the cycle begins all over again. Now with this being said, there is much more than just this!
Good luck!
Answer:
C. Deductive reasoning
Explanation:
Deductive reasoning is a reasoning or logical process whereby a conclusion is drawn based on the belief of multiple premises that are generally assumed to be true. It is a logical process in which one or multiple statements reaches a logical conclusion.
In the question, the statement assumed to be true is that <em>noble gases are unreactive because of their electronic structures.</em>
The conclusion thus drawn from the premise is that <em>if other elements could be made to achieve noble gases electronic structures (</em><u><em>this is the reason why they are unreactive - the fact)</em></u><em> they would be more stable.</em>
<em />
Therefore, deductive reasoning moves from a wilder reasoning to a specific (narrower) reasoning.
Answer:
density/volume
Explanation:
Divide the object’s weight by the acceleration of gravity to find the mass.
C: 0,75M
V: 500mL = 0,5L
...........
C = n/V
n = C×V
n = 0,75×0,5
n = 0,375 mol
...........
mNaCl: 23+35,5 = 58,5 g/mol
58,5g ----- 1 mol
Xg ---------- 0,375 mol
X = 58,5×0,375
X = 21,9375g NaCl
