Answer:

$C_{18}H_{27}NO_3$ is a compound.

Salad dressing is a heterogeneous mixture.

Air is a gaseous homogeneous mixture.

Explanation:

Hello,

At first, $C_{18}H_{27}NO_3$ is named as Capsaicin and is the active component of the chili peppers. It is an organic molecule (compound) containing carbon, hydrogen, nitrogen and oxygen which produces a sensation of burning in any tissue with which it comes into contact.

Secondly, salad dressings are combinations of several ingredients that are available to be used with other types of foods. Those ingredients characterizes the salad dressing as a heterogeneous mixture composed by liquid and solid constituents.

Finally, the air we are breathing is a gaseous homogeneous mixture majorly composed by 79% of nitrogen and 21% oxygen.

Best regards.

Answer:

$\rm _{27}^{60}\text{Co} \longrightarrow \, _{-1}^{0}\text{e} + \, _{28}^{60}\text{Ni}$

Explanation:

The unbalanced nuclear equation is

$\rm _{27}^{60}\text{Co} \longrightarrow \, _{-1}^{0}\text{e} + \, ?$

Let's write the question mark as a nuclear symbol.

$\rm _{27}^{60}\text{Co} \longrightarrow \, _{-1}^{0}\text{e} + \, _{Z}^{A}\text{X}$

The main point to remember in balancing nuclear equations is that the sums of the superscripts and the subscripts must be the same on each side of the equation.

Then

60 = 0 + A, so A = 60 - 0 = 60, and

27 = -1 + Z, so Z = 27 + 1 = 28

Your nuclear equation becomes

$\rm _{27}^{60}\text{Co} \longrightarrow \, _{-1}^{0}\text{e} + \, _{28}^{60}\text{X}$
