Answer:
C. Infinitely Many Solutions
<u>Explanation:</u>
No solution case : This is the case when all given variables are not equal to any constant, for example: there is one row of zeros in matrix <em>e.g 0=3</em>. matrix B don't have any zero row. <u>So, Not True. </u>
One Solution case: This is the case when all variables are independent variables like if they are equal to some constant. <em>e.g x=1,y=2,z=4 </em>, Matrix B have more than one variable in first row due to which it made equation look like <em>x+y=-5. so matrix B can't have only one solution. </em><u>So, Not True.</u>
Infinitely Many Solutions case: when there is one or more variables which is not equal to any constant and acting as linearly dependent variable, then that matrix have infinite solutions. Matrix B have that variable which is linearly dependent as show in the attachment solution.<u> So, True. </u>
the correct answer to your question is Binary Compounds.
Raoult's law is stated as<span> the partial </span>vapor pressure<span> of each component in the </span> mixture<span> of ideal liquids is equal to the vapor pressure of the pure component multiplied by its </span>mole fraction<span> in the mixture. Mathematically, it is expressed as
P = Xi Pi
where P= vapor pressure of solution
Xi = mole fraction of i component
Pi = vapor pressure of pure i component.
In present case, P1 = 0.459 atm and n1 = number of mole of ethanol = 0.090
n2 = number of mole of </span><span> naphthalene = 0.01
</span>∴ Mole fraction of ethanol =
=
= 0.9
Thus, vapor pressure of solution = 0.9 X 0.459 = 0.4131 atm.
Answer: <span>The vapor pressure of pure ethanol at 60 °c is 0.459 atm. Raoult's law predicts that a solution prepared by dissolving 10.0 mmol naphthalene (nonvolatile) in 90.0 mmol ethanol will have a vapor pressure of
0.4131 atm.</span>
So, the negative Ion found in Milk of Magnesia is Hydroxyl Ion (OH⁻).

Answer:
An organism's niche includes food, shelter, its predators, the temperature, the amount of moisture the organism needs to survive, etc. When two or more individuals or populations try to use the same limited resources such as food, water, shelter, space, or sunlight, it is called competition.
