Carbon and iron alloys are called steel.
Answer:
is a compound.
Salad dressing is a heterogeneous mixture.
Air is a gaseous homogeneous mixture.
Explanation:
Hello,
At first, 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.
This problem can be solved by Dalton's law of partial pressures which states that <em>in a mixture of non-reacting gases, the total pressure exerted is equal to the sum of the partial pressures of the individual gases</em>.
Ptotal = P₁ + P₂ + P₃ + ..... + Pn
Herein, Ptotal = P(Ne) + P(Ar) + P(He)
Ptotal = 1.25 atm, P(Ne) = 0.68 atm and P(Ar) = 0.35
So, P(He) = Ptotal - P(Ne) - P(Ar) = 1.25 - 0.68 - 0.35 = 0.22 atm
Answer:
To express y in terms of x is to find an expression that relates the value of x with y. This is to write a model, function, expression or formula that permits to input a value for x and the outcome will be the value of y. .For example if you have y = 2x, y is in terms of x and you can input different values of x to obtain corresponding values (outputs) of y.
