No, because hydrogen isn’t brought out of the equation
A pure substance that cannot be separated into simpler substances by physical or chemical means. A pure substance composed of two or more elements that are chemically combined.
Answer:
combination of a very light gas (hydrogen) and a substance that is found in all living things (carbon). Hydrocarbons are found in petrol, coal and natural gas
Answer:
V = 150 mL
Explanation:
Hello!
In this case, since the molarity of a solution is computed via:
Whereas we are asked to compute the volume:
Thus, we first compute the moles in 12.0 g of NaOH as its molar mass is about 40.0 g/mol:
Thus, at first instance, the volume liters is:
Which in milliliters is:
Best regards!
The equation is:
Ca(OH)₂(s) + 2 HCl(aq) → CaCl₂(aq) + 2 H₂<span>O(l)
</span>
n=mass in g/M.M
15 g Ca(OH)₂ is n=15 g/ 74.1 g/mol=0.2024 mol of Ca(OH)₂
no. of mol of HCl:
n=0.5 mol/L*0.075L=0.0375 mol
This could react with 0.0375/2= 0.01875 mol of Ca(OH)₂ We have a lot more than that.
Therefore, HCl is the limiting reagent and determines how much CaCl₂ forms.
Based on the balanced reaction, 2 moles of HCl gives 1 mole of CaCl₂
no. of mol of CaCl₂= 0.0375/2= 0.01875 mol
mass in g=n*MM= 0.01875*111= 2.08 g
