It is mostly about an element, it usually goes like this: "which element has the bigger atomic size, Sodium or Oxygen? "
Answer: i think the answer is
C. Chemists have learned how dangerous chemicals can be
Explanation:
CO(g) +2H2--->CH3OH
2.50g H2*1mol/2g=1.25 mol H2
30.0L CO*1mol/22.4L=1.34 mol CO,
according to reaction 1 mol CO needs 2 mol H2,so 1.34 mol CO need 2.68 mol H2, so 1) limiting teactant is H2 (H)
2)1.25 mol CH3OH will be produced, 1.25 mol*32g/mol=40.0 g CH3OH
3) 1.25 mol H2 needs 0.625 g CO
1.34-0.625=0.715 g CO leftover
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:
Gases have no definite shape or volume.
