Answer:
D
Explanation:
If you look at the problem, and the coefficients (the little numbers on the bottom) you will see that on the reactant side you get a total of 11, you look over to the product side and you also get a total of 11.
B. is wrong because they’re are the same amounts
C.is wrong because they have the same amount of carbon
D. Now similar to B but slightly different the matter is the reactant side I’m pretty sure is equal to the amount on the product side.
If I had to take a strong guess though I would choose D just because the question is asking for the one that shows The law of conservation of mass. Pls make me brainlist
Answer is: <span>molarity of a solution is 0,401 M.
</span>m(Ca(OH)₂) = 31,3 g.
n(Ca(OH)₂) = m(Ca(OH)₂) ÷ M(Ca(OH)₂).
n(Ca(OH)₂) = 31,3 g ÷ 74 g/mol.
n(Ca(OH)₂) = 0,422 mol.
V(solution) = 1050 mL · 0,001 L/mL = 1,050 L.
c(Ca(OH)₂) = n(Ca(OH)₂) ÷ V(solution).
c(Ca(OH)₂) = 0,422 mol ÷ 1,050 L.
n(Ca(OH)₂) = 0,401 mol/L = 0,401 M.
D.) as you can tell the temperature is the x axis while pressure (atm) is the y axis, so therefore you’d find (0,0.25) which gives u solid because its not near water or gas
Avogadro's Law is the equation of 6.022 x 10^23 so I hope this helps with the question you are trying to ask
