Explanation:
How does a phase change from solid to liquid occur in a substance.
Answer:
As heat is added to solid water, the temperature increases until it reaches 0 °C, the melting point. At this point, the phase change, added heat goes into changing the state from a solid to liquid. Only when this phase change is complete, the temperature can increase .
Solid → Liquid: Melting or fusion
Solid → Gas: Sublimation
Gas → Liquid: Condensation
Explanation:
Given a fixed amount of gas held at constant pressure, calculate the volume it would occupy if a 3. 50 l sample were cooled from 90. 0oc to 30. 0oc.

What mass of glucose (C6H12O6) should be dissolved in 10. 0 kg of water to obtain a solution with a freezing point of -4. 2 ∘C?.
Answer:
4.1kg
Explanation:
I dont kwon but it was ok in the test
The mass of glucose dissolved in the solution is obtained as 4.734 Kg.
We know that;
ΔT = K m i
ΔT = Freezing point depression
K = freezing constant = 1.86 °C/m
m = molality of solution
i = Van't Hoff factor = 1 (molecular solution)
To find the freezing point depression;
Freezing point depression = Freezing point of pure solvent - Freezing point of solution
Since freezing point of water = 0°C
Freezing point depression = 0°C - (-4. 2 ∘C) = 4. 2 ∘C
The molality of the solution is obtained as follows;
m = ΔT/K i
m = 4. 2 ∘C/ 1.86 °C/m × 1
m = 2.63 m
Molality = number of moles/mass of solvent in Kg
Number of moles = mass/molar mass =
Molar mass of glucose = 180 g/mol
Let the mass of solute be m
2.63 = m/180/10
2.63 = m/1800
m = 2.63 × 1800
m = 4734 g or 4.734 Kg

Consider the equilibrium describing the endothermic dissolution of a solid in water. Z n ( o h ) 2 ( s ) − ⇀ ↽ − z n 2 + ( a q ) + 2 o h − ( a q ) if you have a saturated solution at equilibrium, what changes could you make to increase the solubility of the compound?.
To drive this equilibrium in the forward direction, for a saturated solution, the temperature of the system must be increased.
We have been told that the reaction; Zn(OH)2 ( s ) ⇄ Zn2+(aq) + 2OH − (aq), is an endothermic reaction. Recall that in an endothermic reaction, energy is absorbed and the energy of the products is greater than that of the reactants.
In order to drive this equilibrium in the forward direction, for a saturated solution, we can Increase the temperature of the solution. More Zn(OH)2 will dissolve in the solution.

A. $234,000 b. $158,000 c. $11,000 d. $567,000 Please select the best answer from the choices provided A B C D.
Answer:
B
Explanation:
The face value of the largest 20-year term policy that Maria, age 28, can buy without spending more than $300 premium annually is b. $158,000.
Data and Calculations:Expected annual premium payable = $300
Term period = 20 years
Annual life insurance premium (per 1,000 dollars of face value) for age 28 are as follows:
A 10-year term for female is 1.28,
15 year term for female is 1.54
20 year term for female is 1.89
Whole life for female is 9. 46
Annual Premium = Premium Rate/$1,000 x Face Value
Face Value = Annual Premium/Premium Rate x $1,000
Face Value = $158,730 ($300/$1.89 x $1,000)

What is the measure of arc BEC in circle D? 134° 150 209° 210°.
Answer:
134°
Explanation:
The measure of arc BEC in circle D is 134°. The correct option is 1.
What is circle?A circle is a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called "centre".
The line of reflection symmetry is formed by every line that passes through the circle.
We've been given a circle image and asked to calculate the measure of arc BEC.
That angle is visible to us. ABC is an inscribed angle, and its measure is one-half the length of its subtended arc.
Here,
AC = 2 x m∠ABC
AC = 2 x 75°
AC = 150°
We can set an equation to find the measure of arc BEC because we know that the circumference of a 360 degree is:
Arc BEC + Arc AB + Arc AC = 360°
Arc BEC + 76° + 150° = 360°
Arc BEC + 226° = 360°
Arc BEC = 134°
Thus, the answer is 1.

Explanation:
How many moles are represented by 12. 33 g of carbon dioxide?.
Explanation:
formula:
mass - moles = mass given ÷ molar mass
R.M.M of CO2 = 32 + 6 = 38
Molar mass of CO 2 = 38g (recall that r.m.m = molar mass)
38g of CO2 will produce 1 mole
therefore 12.33g will produce:
12.33÷38g (recall formula above)
answer: 0.324 moles
Which of these is the function of the external oblique muscles?.
The external oblique muscle is located in the abdomen, towards the anterior and lateral part, whose function is related to the rotation of the torso and lateral compression of the abdomen.
The external oblique muscle is a muscle with skeletal striated fibers, together with the minor oblique, pyramidal, transverse and rectus major are those located in the anterior and lateral abdominal area.
Its main function at the moment of contracting its fibers on one side of the abdomen, is to produce a rotation of the thorax accompanied by the movement of the upper part of the contracted muscle to the opposite side.Participates in forced expiration and stabilizes the lumbar spine when lifting weights and the muscles that originate from the pelvis.

A desert is very hot during the day and receives very little rain. Which plants will likely survive in this kind of environment?.
Explanation:
A cactus is a plant that would survive
A desert is very hot during the day and receives very little rain. The plants that will likely survive in this kind of environment are plants with waxy coatings. Thus the correct option is A.
What is the environment?The environment is referred to as the surroundings where all living and nonliving things are present. The environment contains different types which include the atmosphere, hydrosphere, lithosphere, and biosphere.
Desert is referred as dryland which constitutes more than one-fifth of the planet's landmass and can be found on every continent. These regions experience a "moisture imbalance," which indicates that they typically lose more moisture to drainage.
The gravity of the waxy substance on their leaves, floating plants, which have short branches, would sink underwater if not for the weight of the leaves. The plant is shielded from hazards outside by the waxy layer, which also holds moisture.
Therefore, option A is appropriate.

What mass of glucose (C6H12O6) should be dissolved in 12. 0 kg of water to obtain a solution with a freezing point of -5. 8 ∘C?.
Answer:
6.740 kg
Explanation:
6.740 kg is the mass of glucose (C6H12O6) should be dissolved in 12. 0 kg of water to obtain a solution with a freezing point of -5. 8 ∘C.
The temperature at which a liquid freezes is known as the freezing point. The freezing point normally rises with increased pressure, much like the melting point does. Combinations and some organic materials, such lipids, have freezing points that are lower than melting points.
The freezing point of a material is the temperature at which a liquid turns into a solid. The liquids' freezing temperatures can be super-cooled much below, postponing the point at which they solidify. The freezing point of water is 0 °C, or 32 °F.
The most common and commonplace example of freezing is the creation of ice cubes in an ice tray when water is placed in the freezer for a period.
Thus, it is 6.740 kg.
