Answer:
Explained below:
Explanation:
The global temperature means the fluctuations in the temperature of the atmosphere and the oceans (existing in the earth surface).
Is the Earth’s global temperature is maintained or not depends on how much sunlight hits Earth versus and how much is returned, it also depends on the atmospheric level of carbon dioxide which prevents the earth from extreme cooling during the night.
Noble gasses I think I could be wrong tho
Given :
Initial mass , a = 150 gm .
Half time ,
.
Final mass , x = 18.75 gm .
To Find :
The time taken to decay 18.75 gm .
Solution :
We know , time taken is given by :
Here , k is a constant given by :
Putting all given value in above equation :
We get :
Therefore , time taken is 6.94 hours .
Hence , this is the required solution .
Mass is always conserved in a physical change. Energy may be released or absorbed when a substance changes from one physical state to another. In a chemical change, a chemical reaction yields a completely new substance. A substance's particles are changed during a chemical reaction.
The consumption of antacid affect urine pH by increasing the pH of urine. Sodium bicarbonate or antacid neutralizes the acidity in the stomach. It is expelled in the body through the urine by alkalizing it. Hope this answers the question.
