Answer:
C₅H₁₁Cl
Explanation:
Count all the carbon, hydrogen, and chlorine atoms. The number of atoms of each element is the subscript for each element in the formula. No subscript is understood to be one. Carbon goes first, hydrogen goes second, and chlorine goes last when writing the formula.
We can use a simple equation to solve this problem.
d = m/v
Where d is the density, m is the mass and v is the volume.
d = ?
m = 87.47 mg = 87.47 x 10⁻³ g
v = 0.03 mL
By applying the equation,
d = 87.47 x 10⁻³ g
/ 0.03 mL
d = 2.92 g/mL
Hence, the density of the mixture is 2.92 g/mL.
Answer:
- Not balanced.
- Reactants: Zn and HCI
.
- Products: ZnCl₂ and H₂.
- Substitution reaction.
Explanation:
Hello,
In this case, for the given reaction:
Zn + HCI → ZnCl₂ + H₂
We can see that it is not balanced due to the fact that at the left side we have one hydrogen atom whereas at the right side two, taking into account the number must be same as well as chlorine. Thus, in order to balance we write:
Zn + 2HCI → ZnCl₂ + H₂
And that is enough. Moreover, we can see that the chemical species at the left side of the equation are the reactants and those at the right side the products, thus we have:
Reactants: Zn and HCI
.
Products: ZnCl₂ and H₂.
Finally, since we can see that the chlorine is at the reactants with hydrogen, but at the end with the zinc, and the initial zinc is alone as well as the yielded hydrogen we can infer this is a substitution reaction.
Best regards.
