Answer:
Beginning from the innermost layer and moving towards the outermost of the sun that has six layers.
1. Innermost layer is the core: All the energy of the sun comes from core. Here hydrogen and helium are components that are present.
2. Radiative zone: The high-energy photons are move from the innermost core to the second innermost radiative zone.
3. Convective zone: It is a comparatively cooler layer to the core and radiative zone.
4. Photosphere: It is the 4th innermost region with sunspots and called the magnetic field of the sun.
5. Chromosphere: This red color layer with filaments of gas is cooler than the photosphere.
6. Corona: It is the outermost layer of the sun and the temperature is much higher here.
if 5.0g zinc reacts with 10.0 g hci to produce h2 gas and znci2 according to the following equation zn=2hci znci2 + h2 what is the limiting reactant and how many grams of h2 will be produced
Answer: The mass of [tex]H_2[/tex] produced is 0.153 g
Explanation:
The number of moles is defined as the ratio of the mass of a substance to its molar mass. The equation used is:
[tex]\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}[/tex] ......(1)
For zinc:Given mass of zinc = 5.0 g
Molar mass of zinc = 65.38 g/mol
Putting values in equation 1, we get:
[tex]\text{Moles of zinc}=\frac{5.0g}{65.38g/mol}=0.0765mol[/tex]
For HCl:Given mass of HCl = 10.0 g
Molar mass of HCl = 36.46 g/mol
Putting values in equation 1, we get:
[tex]\text{Moles of HCl}=\frac{10.0g}{36.46g/mol}=0.274mol[/tex]
The given chemical equation follows:
[tex]Zn+2HCl\rightarrow ZnCl_2+H_2[/tex]
By stoichiometry of the reaction:
If 1 mole of zinc reacts with 2 moles of HCl
So, 0.0765 moles of zinc will react with = [tex]\frac{2}{1}\times 0.0765=0.153mol[/tex] of HCl
As the given amount of HCl is more than the required amount. Thus, it is present in excess and is considered as an excess reagent.
Thus, zinc is considered a limiting reagent because it limits the formation of the product.
By the stoichiometry of the reaction:
If 1 mole of zinc produces 1 mole of [tex]H_2[/tex]
So, 0.0765 moles of zinc will produce = [tex]\frac{1}{1}\times 0.0765=0.0765mol[/tex] of [tex]H_2[/tex]
We know, molar mass of [tex]H_2[/tex] = 2 g/mol
Putting values in above equation, we get:
[tex]\text{Mass of }H_2=(0.0765mol\times 2g/mol)=0.153g[/tex]
Hence, the mass of [tex]H_2[/tex] produced is 0.153 g

HELP ME WITH ONE OR BOTH OF THESE QUEATIONS PLEASEEEE
Answer:
2. 181.25 K.
3. 0.04 atm.
Explanation:
2. Determination of the temperature.
Number of mole (n) = 2.1 moles
Pressure (P) = 1.25 atm
Volume (V) = 25 L
Gas constant (R) = 0.0821 atm.L/Kmol
Temperature (T) =?
The temperature can be obtained by using the ideal gas equation as illustrated below:
PV = nRT
1.25 × 25 = 2.1 × 0.0821 × T
31.25 = 0.17241 × T
Divide both side by 0.17241
T = 31.25 / 0.17241
T = 181.25 K
Thus, the temperature is 181.25 K.
3. Determination of the pressure.
Number of mole (n) = 10 moles
Volume (V) = 5000 L
Temperature (T) = –10 °C = –10 °C + 273 = 263 K
Gas constant (R) = 0.0821 atm.L/Kmol
Pressure (P) =?
The pressure can be obtained by using the ideal gas equation as illustrated below:
PV = nRT
P × 5000 = 10 × 0.0821 × 263
P × 5000 = 215.923
Divide both side by 5000
P = 215.923 / 5000
P = 0.04 atm
Thus, the pressure is 0.04 atm

A stock solution of calcium sulfate, CaSO4 has a concentration of 3.00 M. The volume of this solution is 150 mL. What volume of a 1.25 M solution could be made from the stock solution?
Answer: The volume of stock solution needed is 62.5 mL
Explanation:
A solution consists of solute and solvent. A solute is defined as the component that is present in a smaller proportion while the solvent is defined as the component that is present in a larger proportion.
To calculate the volume of stock solution needed, the formula used is:
[tex]C_1V_1=C_2V_2[/tex] ....(1)
where,
[tex]C_1\text{ and }V_1[/tex] are the concentration and volume of stock solution.
[tex]C_2\text{ and }V_2[/tex] are the concentration and volume of diluted solution.
We are given:
[tex]C_1=3.00M\\V_1=?mL\\C_2=1.25M\\V_2=150mL[/tex]
Putting values in equation 1, we get:
[tex]3.00\times V_1=1.25\times 150\\\\V_1=\frac{1.25\times 150}{3.00}\\\\V_1=62.5mL[/tex]
Hence, the volume of stock solution needed is 62.5 mL

Explain the difference between solid,liquid an gaseous in the theorotical
Answer:
Difference between Solid Liquid and Gases
Solids Liquids Gases
Highly Strong intermolecular forces between the molecules, leads to a definite volume in Solids. The intermolecular forces are stronger than gases but weaker than solids. The intermolecular forces are practically non-existent. Thus, there is no definite volume.
Solids have a definite shape to them. Liquids do not have a definite shape. Gases do not have a definite shape.
The intermolecular space between solids is absent. The intermolecular space is moderate but present. The intermolecular space is free-flowing and plenty.
The force of attraction between the molecules is incredibly high. The force of attraction between molecules is pretty moderate. There is no intermolecular force of attraction between the molecules.

calculate the pressure that this gas will exert on the container in kPa, then
to
go into the lab and measure this pressure.What will he determine is the
pressure of the gas?
Answer:
205.12 atm
Explanation:
Using the ideal gas law equation:
PV = nRT
Where;
P = pressure (atm)
V = volume (L)
R = 0.0821 Latm/perK)
T = temperature (K)
n = number of moles (mol)
According to the information in this question;
P = ?
V = 34.25 mL = 34.25 ÷ 1000 = 0.03425L
n = 0.215 mol
T = 125.0°C = 125 + 273 = 398K
Using PV = nRT
P = nRT ÷ V
P = (0.215 × 0.0821 × 398) ÷ (0.03425)
P = 7.025 ÷ 0.03425
P = 205.12 atm

Explanation:
A 0.520 g sample of an unknown nonelectrolyte compound is dissolved in 4.12 g of lauric acid (Kf = 3.90 °C/m). The freezing point depression is determine to be 4.20 °C. What is the molar mass of the compound?
The molar mass of the unknown nonelectrolyte compound is
Using the formula;
∆T = K m i
Where;
K = freezing point depression constant
m = molality of the solution
i = Van't Hoft factor
Note that i = 1 since the compound is a nonelectrolyte.
To find molality;
Number of moles = 0.520 g/Molar mass
Let the molar mass of the unknown compound be MM
Number of moles = 0.520 g/MM
Number of kilograms of solvent = 4.12 g/1000 = 0.00412 Kg
Molality = 0.520 g/MM * 1/0.00412 Kg
Freezing point depression is 4.20 °C
To find the molar mass of the compound;
4.20 °C = 3.90 °C/m * 0.520 g/MM * 1/0.00412 Kg
4.20 = 492.23/MM
MM = 492.23/4.20
MM = 117.19 g/mol

Assume there are enough reactants to complete the reaction. The final answer should be rounded to one place after the decimal point.
4.3 grams 2.2 grams 1.1 grams 3.9 grams
please answer quick!
Answer:
the answer is 1.1grams is the currect ans
According to the law of conservation of mass, 1.1 grams of calcium carbonate are formed if 2.2 grams of CaO are used for this reaction.
What is law of conservation of mass?According to law of conservation of mass, it is evident that mass is neither created nor destroyed rather it is restored at the end of a chemical reaction .
Law of conservation of mass and energy are related as mass and energy are directly proportional which is indicated by the equation E=mc².Concept of conservation of mass is widely used in field of chemistry, fluid dynamics.
Law needs to be modified in accordance with laws of quantum mechanics under the principle of mass and energy equivalence.This law was proposed by Antoine Lavoisier in the year 1789.If 56 g CaO gives 46.2 g calcium carbonate then 2.2 g CaO will give 2.2×46.2/56=1.1 g.
