Tissues are a group of cells that work together to perform a specific function
Answer:
Option B
Explanation:
All people who are asked to testify in a criminal case must first be issued a subpoena by law enforcement, is a "false statement" or option B. A subpoena is a request to appear in court which is usually given out by the attorneys who are a part of the case, the law enforcement does not give out subpoenas, so this is indeed a false statement.
Hope this helps.
Answer:
12 moles of water (H₂O)
Explanation:
We'll begin by writing the balanced equation for the reaction. This is illustrated below:
6CO₂ + 6H₂O —> C₆H₁₂O₆ + 6O₂
From the balanced equation above,
6 moles of H₂O reacted to produce 1 mole of C₆H₁₂O₆.
Finally, we shall determine the number of mole of H₂O required to produce 2 moles of C₆H₁₂O₆. This can be obtained as follow:
From the balanced equation above,
6 moles of H₂O reacted to produce 1 mole of C₆H₁₂O₆.
Therefore, Xmol of H₂O will react to produce 2 moles of C₆H₁₂O₆ i.e
Xmol of H₂O = 6 × 2
Xmol of H₂O = 12 moles.
Thus, 12 moles of water (H₂O) is needed to produce 2 moles of glucose (C₆H₁₂O₆).
You mix 35mL of 0.54M NaI with 14mL of 0.84M Pb(NO3)2.
We need to first add both of the solution volumes together 35+115=150. Now we can divide the volume of the ethanol by the total volume 35/150=.233. To double check we can multiply the total volume by the percentage of ethanol by volume we got as a solution 150x.233=35. So the percentage by volume of ethanol in the solution is .233x100=23.3%.
