Answer:
A bird's feathers are supposed to keep the bird warm and help them fly. A tree's bark is supposed to protect the inside of the tree.
Explanation:
If a tree has no bark, the inside of it is exposed. If a bird has no feathers, the bird is cold and cant fly.
Attached is a word document that contains a picture of the drawing as well as the explanation. Let me know if the picture is not showing up or if my hand writing is too hard to read so that I can type the explanation in the comments for this answer.
the major points for the answer was that the Sn²⁺ is reduced while the Cr is oxidized and that the Sn electrode is the cathode while the Cr electrode is the anode. The electrons travel from the anode to the cathode while the anions travel from the cathode to the anode.
I hope this helps. Let me know if anything is unclear or if you want me to explain anything further.
Answer:
True True False
Explanation:
Valves are in most veins (to prevent backflow). Also valves in the chart and an in an combustion engine.
So the first statement is True.
Valves control the flow rate and direction of fluid within a closed system. So the second statement is True.
1 Pa = 1 N/m² So since 1 Pa equals to one newton per square metre the third statement is False.
Answer:- 0.143 M
Solution:- HCl and NaOH reacts in 1:1 mol ratio as shown in the below reaction:
Let's calculate the initial moles of HCl and the moles of NaOH added to it:
= 0.075 mol HCl
= 0.025 mol NaOH
Since they react in 1:1 mol ratio, 0.025 mol of NaOH will react with 0.025 moles of HCl.
Remaining moles of HCl = 0.075 - 0.025 = 0.050
Total volume of the resulting solution = 0.250 L + 0.100 L = 0.350 L
So, the concentration of HCl in the resulting solution = 
= 0.143 M
Hence, the concentration of HCl acid in the resulting solution is 0.143 M.
Hi , your answer is Ionic.
