Poison ivy is an invasive plant species that will invade an environment and take up the nutrients in the soil and rapidly multiply.
Many times the mocking jay will invade the territory of other birds and use its mimicry to lure in birds and make them leave the area, mocking birds are extremely territorial and will use other birds nests
<span>If all chemical reactions that release free energy tend to occur spontaneously,why haven't all such reactions already occurred? One reason is that most reactions require an input of energy to get started.Before it is possible to form new chemical bonds,even bonds that contain less energy,it is first necessary to break the existing bonds,and that takes energy.The extra energy required to destabilize existing chemical bonds and initiate a chemical reaction is called activation energy.</span>
Answer:
109.0
Explanation:
When adding or subtracting values, you must round your answer to the same "place" as the measurement with its last significant figure <em>furthest to the left</em>.
That is, you round off to the same number of decimal places as the measurement with the <em>fewest decimal places</em>.
43.<u>0
</u>
50.<u>0</u>
<u>+16.0
</u>
109.<u>0</u>
In each measurement, the “0” is the significant figure furthest to the left, so you round off the number to the “tenths" place. That's the last column that the measurements share.
109.0 → 109.0 (rounded to the “tenths” place)
In other words, you do not round off, and the sum has four significant figures.
Answer:
2NaCl + H2SO4 ----> Na2SO4 + 2HCl
Explanation:
Answer : The answer is, 
Explanation :
Scientific notation : It is defined as the way or representation of expressing the number that are too big or too small that is written in the decimal form. That means always written in the power of 10 form.
For example : 8000 is written as, 
in this notation, the significant figure is, 1 but 
in this notation, the significant figures are, 2
The given problem are :
According to the divide and multiplication rules of scientific figures, the final answer is only as precise as the value with the least number of significant figures.
Hence, the answer is,
