Answer:
The more polar the liquid, the more likely that it is miscible with water. The polarity of a liquid does not affect its miscibility with water. The less polar the liquid, the more likely that it is miscible with water. The more polar the liquid, the less likely that it is miscible with water.
Explanation:
hope it helps you
Miscibility of two liquids are directly related to their polarity. The likelihood that a liquid will mix with water increases with its polarity.
What is polarity?Polarity is the arrangement of electrical charge among the atoms connected by a chemical bond. Because both hydrogen atoms in H2 were electrically neutral, bonds among atoms of different elements were electrically inequivalent, as opposed to bonds among identical atoms, which are electrically uniform.
The likelihood that a liquid will mix with water increases with its polarity. Liquid miscibility with water is unaffected by the polarity of the liquid. The likelihood that a liquid will mix with water increases with decreasing polarity. The likelihood that a liquid will be miscible with water decreases with increasing polarity.
Therefore, miscibility and polarity are directly related.

what word describes when tiny droplets of one liquid are finely dispersed within another liquid?
When tiny droplets of one liquid are finely dispersed within another liquid it is called emulsion.
Emulsion can be defined as the process by which two liquids that are not miscible come together to form a mixture.
The emulsion mixture usually consists of an oil phase and a water phase.
The oil phase appears as droplets when dispersed (mixed with) the water phase.

How much heat is absorbed when 25 g of water increases by 45 K?
4709.25 joules of heat are absorbed when 25 grams of water increases temperature by 45 K.
Let suppose that temperature change experienced by water is entirely sensible. Then, we can estimated the heat absorbed by the water sample ([tex]Q[/tex]), in joules, through this expression:
[tex]Q = m\cdot c \cdot \Delta T[/tex] (1)
Where:
[tex]m[/tex] - Mass of the water sample, in grams.[tex]c[/tex] - Specific heat of water, in joules per kilogram-Kelvin.[tex]\Delta T[/tex] - Temperature change, in Kelvin.If we know that [tex]m = 25\,g[/tex], [tex]c = 4.186\,\frac{J}{g\cdot K}[/tex] and [tex]\Delta T = 45\,K[/tex], then the heat absorbed by the water sample is:
[tex]Q = (25\,g)\cdot \left(4.186\,\frac{J}{g\cdot K} \right)\cdot (45\,K)[/tex]
[tex]Q = 4709.25\,J[/tex]

A container holds 2.0 liters of a gas at 5.0 atmospheres of pressure. If both the temperature and the amount of gas are kept constant while the volume is doubled, what is the new pressure of the gas A 0.5 L B 1.0L C 4.0 L D 8.OL
The new (final) pressure of the sample of gas is equal to 2.5 Liters.
Given the following data:
Initial volume = 2.0 LitersFinal volume = 4.0 LitersInitial pressure = 5.0 atm.Note: The initial volume was doubled.
To determine the new (final) pressure of the sample of gas, we would apply Boyle's law:
Mathematically, Boyle's law is given by the formula;
[tex]PV = k\\\\P_1V_1 = P_2V_2[/tex]
Where;
[tex]P_1[/tex] is the initial pressure.[tex]P_2[/tex] is the new (final) pressure.[tex]V_1[/tex] is the initial volume.[tex]V_2[/tex] is the final volume.Making [tex]P_2[/tex] the subject of formula, we have:
[tex]P_2 =\frac{P_1V_1}{V_2}[/tex]
Substituting the given parameters into the formula, we have;
[tex]P_2 = \frac{5.0 \times 2.0}{4.0} \\\\P_2 = \frac{10}{4.0}[/tex]
New volume = 2.5 Liters

400.0 mL of a 0.425 M solution of NaCl is diluted to 900.0 mL. What is the new concentration of the solution
The new concentration of the solution that has 400.0 mL of a 0.425 M solution of NaCl diluted to 900.0 mL is 0.189M
HOW TO CALCULATE CONCENTRATION:
The concentration of a diluted solution can be calculated using the following formula:C1V1 = C2V2
Where;
C1 = initial concentrationC2 = final concentrationV1 = initial volumeV2 = final volumeAccording to this question, a solution of NaCl has 400.0 mL of a 0.425 M solution and diluted to 900.0 mL. The new concentration is as follows:400 × 0.425 = 900 × C2
170 = 900C2
C2 = 170 ÷ 900
C2 = 0.189M
Therefore, the new concentration of the solution that has 400.0 mL of a 0.425 M solution of NaCl diluted to 900.0 mL is 0.189M.Learn more at: https://brainly.com/question/8795644?referrer=searchResults

Answer:

Good Luck.
Explanation:
The number of valence electrons for neutral atoms is the same as the number of the atom's main group.A periodic table element's column can be used to determine its main group number.For instance, carbon, which belongs to group 4, has four valence electrons.
Use the periodic table to identify the number of valence electrons available for bonding for each of the following elements?
This rule states that each group of elements has one valence electron, two valence electrons in group 2, three valence electrons in group 13, four valence electrons in group 14, and so on. C : Six electrons make up the atom of carbon: four valence (outermost shell) electrons in the 2s and 2p orbitals, and two inner shell (core) electrons in the 1s orbital. H : As the initial element, hydrogen has an electron configuration of 1s1.Its valence shell only contains one electron.The outermost electrons or those with the highest energy level are called valence electrons. N : The periodic table's Group 15 is headed by nitrogen, which has either 3 or 5 valence electrons. O : On the periodic table, column 6 contains oxygen (symbol O).Its valence electrons number six.To obtain an octet, two bonds must be created. Ci : If chlorine removes one of its seven valence electrons, it will have eight (an octet).When chlorine gains one electron, its electron configuration resembles that of argon.If chlorine had given up all seven of its valence electrons and sodium had taken them, the octet rule would have been met.To learn more about periodic table refer

How many atoms are there in 7.02 g Si ?
Answer:
1.51e23 atoms
Explanation:
First, using the molar mass of Si (28.1 g/mol), determine the # of moles of Si we have. Then use Avogadro's number (6.022e23 atoms = 1 mol) to convert the # of moles to the # of Si atoms.
(7.02 g Si)([tex]\frac{1 mol}{28.1 g}[/tex]) = 0.250 mol Si
(0.250 mol Si)([tex]\frac{6.022*10^{23} atoms }{1 mol}[/tex]) = 1.51e23 atoms
The atomic mass of Silicon (Si) is 28.09 g/mol. The no. of atoms present in 7.02 g of Si is 1.46 × 10²³.
What is a mole?Any substance containing 6.022 × 10²³ atoms is called one mole of that substance. The no.of moles can be calculated by dividing the given weight by the atomic mass of the substance.
Atomic mass of Si = 28.09 g/mol
Given mass = 7.02 g.
No.of moles = 7.02 g/ 28.09 g/mol
= 0.24 moles
One mole contains 6.02 × 10²³ atoms. Thus 0.24 mole of Si contains 6.02 × 10²³ × 0.24 = 1.46 × 10²³ atoms.
Hence, no.of atoms present in 7.02 g of Si is 1.46 × 10²³ .
