Answers
Answer: The volume of given ball is 21 L.
Explanation:
Given : Pressure = 1.0 atm, no. of moles = 0.85 mol
Temperature = [tex]25^{o}C = (25 + 273) K = 298 K[/tex]
According to the ideal gas equation, formula used is as follows.
PV = nRT
where,
P = pressure
V = volume
n = no. of moles
R = gas constant = 0.0821 L atm/mol K
T = temperature
Substitute the values into above formula as follows.
[tex]PV = nRT\\1.0 atm \times V = 0.85 mol \times 0.0821 Latm/mol K \times 298 K\\V = 21 L[/tex]
Thus, we can conclude that the volume is 21 L.

Identify one possible observation based on the type of reaction or the state of products when magnesium and chloride react.
Answers
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.

How much so you can be dissolved and 50 mL of water at 30 Celsius see chart:)
Answers
Answer:
The correct answer is - 100 grams.
Explanation:
The solubility graph is a very useful tool because it tells you the amount of solute that can be dissolved per 100 mL of water in order to have a saturated solution of potassium nitrate at a given temperature.
In order to find the solubility of the salt at 30 ∘ C , start from the 30 ∘ C
mark on the graph and move up until you intersect the curve. At the point of intersection, move left until you intersect the y axis and read off the value that you land on which is 200. However, it is for 100 ml so half the value you read:
200/2 = 100 gram .
So, solubility ≈ 100 g / 50 mL water
So, a saturated solution of solute will hold about 100 g of dissolved solute, that is of dissociated solute, per 50 mL of water at 30 ∘ C .

What is the reason why oil and water are immiscible?
Someone HELP
Answers
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.
What is the systematic name of the following compound?
CaF 2
Answers
First, identify and name the cation (the positive ion): Here, that would be the calcium (Ca2+) ion.
Next, identify and name the anion (the negative ion). Here, that would be the fluoride ion (F-). The anionic form of an element’s name can often be obtained by retaining the root and replacing the ending with -ide (e.g., sulfur becomes sulfide; oxygen becomes oxide; nitrogen becomes nitride; chlorine becomes chloride; bromine becomes bromide; etc.).
So the systematic name of CaF2 would be calcium fluoride.

Which of the following scientists was the first to determine the
relationship between the pressure and volume of a gas?
Answers
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]
Where;
V1 and V2 represents the initial and final volumes respectively.
T1 and T2 represents the initial and final temperatures respectively.

what happen to water when it boils
Answers
When water is boiled, the heat energy is transferred to the molecules of water, which begin to move more quickly. Eventually, the molecules have too much energy to stay connected as a liquid. When this occurs, they form gaseous molecules of water vapor, which float to the surface as bubbles and travel into the air.

Answers
Answer:
La respuesta está en la explicación
Explanation:
Al realizar este análisis, el químico estará obteniendo la masa que la sustancia desconocida ocupa en un volumen determinado, a esto se le conoce como La Densidad de la Sustancia.
La densidad se puede definir como la masa (En gramos) que pesa una sustancia que ocupa 1mL. Así, la densidad de esta sustancia será:
38.5g / 45mL =
0.856g/mL es la densidad de esta sustancia
Ahora, debes identificar en la tabla, cuál sustancia tiene una densidad similar a la obtenida y, de esta manera, podrías saber a cuál sustancia corresponde.

In an endothermic reaction, activation potential energy of reactants is less than that of the products. Reactants in endothermic reaction are absorbing enough heat energy to overcome this barrier potential. Hence, option B is correct.
What is an endothermic reaction?An endothermic reaction is the one in which heat energy is absorbed by the reactants from the surroundings. In endothermic reactions, the enthalpy change is positive.
The minimum energy that the reactants have to acquire for effective collision and reaction is called the activation energy. By absorbing heat energy reactants becomes more energetic and overcome this activation potential.
Therefore, in an endothermic reaction, the activation potential of products will be higher than that of the reactants and the energy diagram clearly exhibit this transition in energy. Hence, option B is correct.

Convert 1.4 x 1024 molecules of H2O to grams of H20.
Answers
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
