There are 30 inches in 2.5 just know that a foot is 12 inches so 12 times 2.5 is 30
I added a screenshot because I recently answered the same question. I hope this helps you!! :)
The answer to this item depends entirely to the chemical reaction. If the compound, NH4Cl, is in the left hand side of the reaction, when it is added, the reaction will shift to the left. In the same manner, when the compound is in the right-hand side of the reaction, the reaction will shift to the right.
This happens because initially the reaction is in equilibrium and adding another compound to it will most likely lead to the shifting of the reaction.
Answer:
B. C, A, B
Explanation:
We can measure the age of an artifact by comparison of the activities a living sample with that of the artifact. This is so because the activity of the living sample represents the original activity of the artifact.
So, the steps involved in determining the age of an artifact is to measure the ratio of the parent and daughter nuclei. Then we use the half life of carbon to find out how many half lives have passed. Using this number of half lives that has passed, we can compute the age of the object.
Answer:
C
Explanation:
cause it looks right and I also studied but wait til someone gives another answer
