Answer:
B. Atom, molecule, cell, organism
Explanation:
Atoms make up molecules. Molecules make up cells. Cells make up tissue. A number of tissues working together creates an organ. Multiple organs working together creates an organ system. Organ systems working together creates one happy, functioning organism. :)
The volume will increase i am pretty sure hope its right good luck!
Answer:
25.6mL NaOH
Explanation:
We are given the Molarity of the solution () and the volume of the solution (.02L).
By multiplying the two together, we can find the moles of solution that are reacted with HCl.
This gives us .0082 moles of HCl.
We then find the moles of NaOH that are needed to react with the HCl using the equation.
As HCl and NaCl have a 1:1 ratio, we need .0082 mol of NaOH.
Dividing this value by the Molarity of the solution
Gives us the answer, in Liters (.0256), which we can then divide by 100 convert to mL.
Answer:
The pressure is equal to 0.775 atm.
Explanation:
Given that,
The atmospheric pressure on Stevens pass was measure to be 589mmHg.
We need to find the pressure in atm.
We know that,
1 standard atmosphere = 760 mm Hg
1 mm Hg = (1/760) standard atmosphere
589 mm Hg = (1/760)× 589 standard atmosphere
= 0.775 standard atmosphere
Hence, the pressure is equal to 0.775 atm.
