mercury
Answer:
When the Zebra arrived they ate all the food so the Unionid mussels declined as they died from the lack of food. Causing the Zebra Zebra numbers to increase and Unionid numbers to decline.
Answer:
Which one goes in the absolute dating column, relative column, and both.
Lesson 4.07: Relative and Absolute Dating DIRECTIONS: Use the facts below to complete the chart for Relative and Absolute Dating.
1. The Law of Superposition – the age of an object may be determined by the depth at which it is found, the deeper the object is in the Earth, the older it is.
2. Gives scientist an exact age of a rock fossil.
3. Scientist use their knowledge of the half-life of carbon and uranium isotopes to measure the age of the rock or fossil .
4. Used to determine the age of an object, when there is no record of a living thing.
5. Gives the approximate age of a fossil or artifact.
6. Used by scientist to determine the age of a fossil or artifact.
7. Estimates the order of geological or prehistoric events, but cannot be used to determine when these events have occurred.
8. Measures the decay of a rock or fossil to measure the age.
Answer:
0.0432 M H2SO4
Explanation:
First, we want to find the moles of MNaOH used. We know that Molarity x Liters = moles. 0.160M x 0.0210L = 0.00336 moles MNaOH
to find the moles of H2SO4, we can use a mol ratio.
0.00336mol MNaOH x (1Mol H2SO4 /2mol MNaOH)
= 0. 00168 mol H2SO4
I found the mol ratio by looking at the coefficients in front of the molecules I knew(MNaOH) and the molecule I needed to find(H2SO4)
then, to find Molarity, we do mol/Liters
0.00168 mol/ 0.0388L =. 0.0432 M H2SO4
You can convert mL to L by dividing by 1000
the significant figures of this problem is 3, so my final answer will also have 3 sig figs.
I am going to say it is false.
