Answer:
COARSE ADJUSTMENT KNOB — A rapid control which allows for quick focusing by moving the objective lens or stage up and down. ... FINE ADJUSTMENT KNOB — A slow but precise control used to fine focus the image when viewing at the higher magnifications. 6.
Coarse adjustment, using the coarse adjustment knobs, raises and lowers the stage more rapidly. Fine adjustment knobs are the smaller knobs and are also used to raise and lower the stage but more slowly and in a more controlled manner under higher magnifications.
Answer:
Zinc reacts with dilute sulphuric acid to produce hydrogen gas (H2) and zinc sulphate. This is an example of displacement reaction of a non-metal by a metal. ... ZnSO4 is different in chemical composition and chemical properties than Zn and H2SO4 so it is a chemical change.
The moles of B that will be needed to convert 2 moles of A into as many moles of C as possible is 6 moles
Explanation
3A +9B → 5C
The moles of B are calculated using the mole ratio.
That is; from the equation above the mole ratio of A:B is 3:9
If the moles of A required is 2 moles therefore the moles of B
= 2 x9/3= 6 moles
Answer:
Not exactly But you can take the slope of the curved portion and the slope of the flatline.
It wont do you much good since your working for absorbance but if you ever see something like a temperature change you can use the slope(s) to find freezing points/melting
Explanation:
If you need to submit a slope you could use a best fit which is just point to point or you could break it up like i mentioned
