What is the reason why oil and water are immiscible?
Someone HELP
Answer:
Liquid water is held together by hydrogen bonds. (Liquid water has fewer hydrogen bonds than ice.) Oils and fats not have any polar part and so for them to dissolve in water they would have to break some of water's hydrogen bonds. Water will not do this so the oil is forced to stay separate from the water.
Identify one possible observation based on the type of reaction or the state of products when magnesium and chloride react.
Answer:
Magnesium chloride.
Explanation:
When magnesium and chloride react with each other produces magnesium chloride. Magnesium belongs to second group in the periodic table which means it has two electrons in its outermost shell while on the other hand, chlorine belongs to seven group which means it has seven electrons in its outermost shell so it needs one electron to become stable. So in the reaction, magnesium loses two electrons and become cation whereas two chlorine atoms receives two electrons from magnesium and become anion. Ionic bond type is present between magnesium and chlorine atoms.

there is 115 mL of a gas is at 45.8 kPa and 57.2°C. What is the volume of the gas at 99.3 kPa and 112.3°C?
Answer:
115 mL of a gas is at 45.8 kPa and 57.2°C. What is the volume of the gas at 99.3 kPa and 112.3°C?[5] 11. ... What is the pressure of 62.76 g of carbon dioxide (CO2) gas if it occupies a volume of 35,000 mL at standard temperature?
Explanation:
By using gas law , the volume will be 61.9 mL .
What is gas law?
According to the gas law, the pressure of a gas generally directly proportional to its temperature at a fixed volume.
Gas law can be represented as:
[tex]P_{1} V_{1}/ T_{1} = P_{2} V_{2} / T_{2}[/tex]
Calculation of volume with the aid of gas law:
It is given that, [tex]P_{1}[/tex] = 45.8 kPa, [tex]P_{2}[/tex] = 99.3 kPa , [tex]T_{1}[/tex] = 57.2°C, [tex]T_{2}[/tex] = 112.3°C, [tex]V_{1}[/tex] = 115 mL .
Now, put the values of given data in gas laws equation.
(45.8kPa)(115mL)/(330K)= (99.3kPa)([tex]V_{2}[/tex])(385.3K)
[tex]V_{2}[/tex] = 61.9 mL
Therefore, the volume will be 61.9 mL .

An unopened, cold 2.00 L bottle of soda contains 46.0 mL of gas confined at a pressure of 1.30 atm at a temperature of 5.0 ℃. If the bottle is dropped into a lake and sinks to a depth at which the pressure is 1.52 atm and the temperature is 2.09 ℃, what will be the volume of the gas in the bottle? Explanation needed
Answer:
[tex]V_2= 38.9mL[/tex]
Explanation:
Hello there!
In this case, since this is a problem about the combined gas law because the temperature, volume and pressure undergo a change:
[tex]\frac{P_2V_2}{T_2}= \frac{P_1V_1}{T_1}[/tex]
Thus, since we need the final volume, V2, we solve for it as shown below:
[tex]V_2= \frac{P_1V_1T_2}{T_1P_2}[/tex]
Now, we plug in the data to obtain:
[tex]V_2= \frac{1.30atm*46.0mL*(2.09+273)K}{(5+273)K*1.52atm}\\\\V_2= 38.9mL[/tex]

How long will it take for the 1.35 mg sample of Pt-236 in to decay to 1.00 mg, half life of Pt-236 is 2.86 years?
Answer:
1.238 years will it take
Explanation:
The isotope decay of an atom follows the equation:
Ln[A] = -kt + ln[A]₀
Where [A] could be taken as the amount of the isotope after t years
[A] = 1.00mg
t = ?
k is the decay constant; k = ln2 / Half-life
k = ln 2 / 2.86 years = 0.2424 years⁻¹
[A]₀ is the initial amount of the isotope = 1.35mg
Replacing:
ln1 = -0.2424years⁻¹*t + ln 1.35
0.2424years⁻¹*t = ln 1.35

Convert 1.4 x 1024 molecules of H2O to grams of H20.
Answer:
41.8 g of water.
Explanation:
To solve this, we introduce the concept of mol.
1 mol of anything contains 6.02×10²³ particles.
In this case, we talk about molecules of water.
Molecular weigh is 18 g/mol which indicates that 1 mol of water weighs 18 g.
So let's do the conversion
(18 g of water / 6.02×10²³ 1 mol of molecules) . 1.4×10²⁴ molecules = 41.8 g

What is the molarity of a 511 ml solution containing
205 mg of NH3?
Answer: The molarity of given solution is 0.0235 M.
Explanation:
Given : Volume of solution = 511 mL
Convert mL into L as follows.
[tex]1 mL = 0.001 L\\511 mL = 511 mL \times \frac{0.001 L}{1 mL}\\= 0.511 L[/tex]
Mass of [tex]NH_{3}[/tex] (solute) = 205 mg
Convert mg into gram as follows.
[tex]1 mg = 0.001 g\\205 mg = 205 mg \times \frac{0.001 g}{1 mg}\\= 0.205 g[/tex]
As molar mass of [tex]NH_{3}[/tex] is 17 g/mol. Hence, number of moles of [tex]NH_{3}[/tex] are calculated as follows.
[tex]No. of moles = \frac{mass given}{molar mass}\\= \frac{0.205 g}{17 g/mol}\\= 0.012 mol[/tex]
Molarity is the number of moles of a solute dissolved in a liter of solution.
[tex]Molarity = \frac{no. of moles}{Volume (in L)}[/tex]
Substitute the values into above formula as follows.
[tex]Molarity = \frac{no. of moles}{Volume (in L)}\\= \frac{0.012 mol}{0.511 L}\\= 0.0235 M[/tex]
Thus, we can conclude that the molarity of given solution is 0.0235 M.

Which of the following scientists was the first to determine the
relationship between the pressure and volume of a gas?
Answer:
Robert Boyle
Explanation:
Robert Boyle was an Irish chemist and is famously referred to as the first modern chemist. He was born on the 25th of January, 1627 in Lismore, Ireland and died on the 31st, December 1691, London, United Kingdom.
Robert Boyle was the first to determine the relationship between the pressure and volume of a gas.
Boyles states that when the temperature of an ideal gas is kept constant, the pressure of the gas is inversely proportional to the volume occupied by the gas.
Mathematically, Boyles law is given by;
[tex] PV = K[/tex]
[tex] P_{1}V_{1} = P_{2}V_{2} [/tex]

A partir de 140 g de n2 y una cantidad de h2 se obtuvo 153G de NH³. Cual es el % de rendimiento de la reacción química
Respuesta:
90.0 %
Explicación:
Paso 1: Escribir la ecuación química balanceada
N₂ + 3 H₂ ⇒ 2 NH₃
Paso 2: Calcular el rendimiento teórico de NH₃ a partir de 140 g de N₂
En la ecuación balanceada, participan de N₂: 1 mol × 28.01 g/mol = 28.01 g y de NH₃: 2 mol × 17.03 g/mol = 34.06 g.
140 g N₂ × 34.06 g NH₃ /28.01 g N₂ = 170 g NH₃
Paso 3: Calcular el rendimiento porcentual de NH₃
El rendimiento experimental de NH₃ es 153 g. Podemos calcular el rendimiento porcentual usando la siguiente fórmula.
R% = rendimiento experimental / rendimiento teórico × 100%
R% = 153 g / 170 g × 100% = 90.0 %
