Answer:
did you ever get the answer lol
Freezing something makes it solid and melting something makes it a liquid
Answer:
This question is incomplete
Explanation:
This question is incomplete. However, the beaker that contained some water before NaOH were added means that the resulting solution in that beaker will be more dilute. When this diluted sodium hydroxide solution is added to HCl (not hci), the reaction below occurs
HCl + NaOH ⇒ NaCl + H₂O
The reaction above is a neutralization reaction. <u>The concentration of the acid (HCl) will reduce when a base (sodium hydroxide) is added and will also reduce more because of the presence of more water (in the base) which normally reduces the concentration of ions present in an acid or a base to become more dilute.</u>
The atomic weight of carbon dioxide is about 12.011 + 15.999 + 15.999 = 44.009.
44.009 grams of CO2 = 1 mole of CO2 CO2 = Carbon dioxide
25 ÷ 44.009 ≈ 0.568
About 0.568 moles of CO2
Answer: 7.56 moles
Explanation:
C3H8 is the chemical formula for propane, the third member of the alkane family.
Recall that based on Avogadro's number, 1 mole of any substance has 6.02 x 10^23 atoms
So 1 mole of C3H8 = 6.02 x 10^23 atoms
Z moles of C3H8 = 4.55 x 10^24 atoms
To get the value of Z, we cross multiply:
1 x 4.55 x 10^24 atoms = Z moles x (6.02 x 10^23 atoms)
4.55 x 10^24 atoms = Z moles x (6.02 x 10^23 atoms)
To get the value of Z divide both sides by 6.02 x 10^23 atoms
Z moles =4.55 x 10^24 atoms ➗ 6.02 x 10*23 atoms
Hence, Z = 7.56 moles
Thus, the number of propane, C3H8 is 7.56 moles
