New technologies have increased the availability of food flavorings as a use of pomace.
What is Pomace?Olive pomace oil is vir-gin olive oil made from the pulp of olives after they have been pressed for the first time. Following mechanical oil extraction, approximately Most other edible oils, such as canola, peanut, and sunflower oil, must be extracted using solvents, which is an industrial method used in the manufacturing of most other edible oils.

Suppose a particular star is projected from a firework at a starting height of 520 feet with an initial upward velocity of 72ft/sec. The equation h= -16t^2+72t+520 gives the star's height in feet at time t in seconds
By finding the vertex of the parabola, we will see that the firework reaches the maximum height in 2.25 seconds.
How long will take to reach the maximum height of the path?
The height of the firework is given by:
h = -16*t^2 + 72*t + 520
This is a quadratic equation, the maximum will be at the vertex.
Remember that for a quadratic equation:
y = a*x^2 + b*x + c
The x-value of the vertex is:
x = -b/2a.
Then for our equation:
h = -16*t^2 + 72*t + 520
The vertex will be at:
t = -72/(2*-16) = 2.25s
This means that the firework will reach the maximum height in 2.25 seconds.

A refrigeration lubricant with a high _____ point may have excessive wax separation, which can clog the system.
Answer:
ozone
Explanation:
A refrigeration lubricant with a high floc point may have excessive wax separation, which can clog the system.
What is floc point?The Floc point of the oil can be described as the temperature at which wax will start to precipitate from a mixture. When a mixture of 90% by volume of R-12 and 10% oil by Volume under the specified conditions.
Since the oil-soluble refrigerants lower the viscosity of the oil and affect both the pour point and cloud point. The floc point of the oil is a more important property where oil miscible refrigerants are used.
The results are used to compare the waxing tendency of the various different oils. It provides a method for determining the waxing tendency of the refrigeration lubricant. Floc point should not be confused with cloud point because cloud point is the temperature at which the wax is precipitated from the undiluted oil.

A block of ice is placed outside on a hot summer dayDescribe the changes in particle motion and the corresponding changes in energy as the ice melts and eventually becomes water vapor .
Answer:
When solid ice gains heat, it changes state from solid ice to liquid water in a process called melting. Ice cubes in a cold drink, for example, gradually melt. ... When water absorbs enough heat, it becomes a gas (water vapor). This process is called evaporation.
Explanation:
When solid converts to gas then heat is required to break the intermolecular forces of attraction between the particles. In this process heat increase but temperature remains the same. Therefore, firstly melting and then evaporation takes place.
What is phase transition?Phase transition is a process in which transition takes place from one state to another of a medium on changing temperature or pressure. Phase transition is a physical process as there is no breaking of old bond and forming of new bonds takes place.
Melting is the process by which solid ice transforms into liquid water when exposed to heat, while evaporation is the process by which it transforms into gas. During evaporation and melting, heat energy is taken from the surrounding.
Therefore, firstly melting and then evaporation takes place.

A salt in which the anion is the conjugate _____ of a weak _____ will produce a basic solution. (Assume that the cation does not hydrolyze.)
Answer: conjugate base of a weak acid
Explanation: If the anion is a conjugate base of a weak acid, the solution would be basic. This is because weak acids do not produce enough hydrogen ions in the solution so does not really affect the acidity, so the conjugate base can react with water in the solution to produce a basic solution.
An atom of oxygen has six electrons in its outermost ring and requires two more to become stable. What is the valence number of oxygen
Answer: Oxygen in its natural state has 6 valence electrons.
Explanation: The atomic number/ proton number of oxygen is 8, as seen on the periodic table. This is equal to the electron number.
This means there are 2 electrons in the core s shell (innermost), and 6 electrons in the p shell (outermost).
Valence electrons are the electrons found in the outermost shell, so Oxygen has 6 valence electrons.
I don't know if you've been taught electron configuration, but Oxygen's electron configuration is: [tex]1s^2 2s^2 2p^4[/tex] . The 2s and 2p are orbitals of the outermost ring in Oxygen, so adding 2+4 = 6 valence electrons.

When 84. 8 g of iron (III) oxide reacts with an excess of carbon
monoxide, iron is produced.
Fe2O3(s) + 3C0 (9) > 2 Fe(s) + 3 CO2 (g)
What is the theoretical yield of iron?
Answer:
Use the balanced equation to determine the theoretical yield. Focus on the chemicals whose quantities you are given or are asked to find. CO is not important as it is excess and will make sure that all of the Fe2O3 will be changed to iron. Remember the quotients (numbers in front of formula) are the number of moles. You are given the mass of Fe2O3 in grams so you will need to convert 1 mole of Fe2O3 into grams (molar mass which, using simple atomic masses = 56x2 + 16x3 = 160g/mol but you use atomic masses that your course requires
Fe2O3(s) + 3CO(g)--> 2Fe(s) + 3CO2(g)
1 mol 2 mol
160g 112g
84.8g (112/160) x 84.8
So now you have the theoretical yield of Fe2O3 and the experimental (actual) yield = 54.3g)
Percentage Yield = (actual yield/theoretical yield) x 100

At 45.2 L cylinder containing C2H2F4 at a pressure of 3.00 atm is connected by the valve to 4060 mL cylinder containing N2H4 at 1.50 atm pressure. Calculate the partial pressuure(atm) of N2H4 when the valve is opened.
The partial pressure of the N2H4 gas is 1.50 atm.
Dalton's law of partial pressureFrom the Dalton's law of partial pressure, the total pressure of a mixture of gases is the sum of the individual partial pressures of all the gases present in the mixture.
We have the following;
C2H2F4 = 3.00 atm
N2H4 = c
Total pressure = 3.00 atm + 1.50 atm = 4.50 atm
