Find the number of moles of in 571,0 g of tetraphosphorous octoxide.
Answer:
Think sorry if i did it wrong The molar mass that is the mass of 6.022 X 1023 atoms of helium is 4g. Hence 1 mole of He = 4 g of He = 6.022 X 1023atoms of He. 1 g of He = (6.022 X 1023) / 4 atoms of He. 52 g of He = (6.022 X 1023X 52 ) / 4 atoms of He.
For Helium,
Number of atoms=Number of moles ×6.022×1023
No of Moles = 6.022×10
2312.044×10
23 = 2.
Now, atomic mass of He=4
Weight = 2×4 = 8 g
The molar mass that is the mass of 6.022 X 1023 atoms of helium is 4g. Hence 1 mole of He = 4 g of He = 6.022 X 1023atoms of He. 1 g of He = (6.022 X 1023) / 4 atoms of He. 52 g of He = (6.022 X 1023X 52 ) / 4 atoms of He.
As we know, gram atoms = gram mole
here, no of moles = 23/46 =2 so no of gram atoms are 2.

A balloon of hydrogen is subjected to vacuum. The initial pressure and volume of hydrogen is 0. 95 atm and 0. 55 L. Calculate the final pressure if the final volume is 1. 22 L?
The final pressure if the final volume is 1. 22 L will be 0.4234 atm
To calculate the final pressure of the hydrogen in the balloon if the final volume is 1.22 L, the ideal gas law can be used. The ideal gas law states that PV = NRT, where P is the pressure, V is the volume, n is the number of moles of gas, R is the ideal gas constant, and T is the temperature.
Since the number of moles and the temperature is not given, we can assume that they remain constant. So we can use the equation PV = k, where k is a constant.
Given the initial pressure and volume of the hydrogen are 0.95 atm and 0.55 L respectively.
0.95*0.55 = k
so k = 0.5175
then the final pressure can be calculated by:
P1V1 = P2V2
0.950.55 = P21.22
P2 = (0.5175) / (1.22) = 0.4234 atm
The final pressure of the hydrogen in the balloon will be 0.4234 atm.

b. What is the molarity when .453 moles are dissolved in .450 Liters of water?
The molarity when .772 moles are dissolved in .500 Liters of water is 0.0015M. The molarity when .453 moles are dissolved in .450 Liters of water is 0.001M.
What is molarity ?The term molarity is defined as the number of moles of solute dissolved in per litre of solution. The unit of molarity is mole, which is denoted by the symbol "M".
M = Number of moles of solute / litre in solution
1. Number of moles of solute = .772 moles
so, 0.772 / 500
= 0.0015 M
2. Number of moles of solute = .453 moles
so, .453 / 450
= 0.001 M
Thus, The molarity when .772 moles are dissolved in .500 Liters of water is 0.0015M. The molarity when .453 moles are dissolved in .450 Liters of water is 0.001M.

The gas in a container has a pressure 300kPa at 27 C. What will the pressure be if the
temperature is lowered to -173 C?
Answer:
100 kPa
Explanation:
This can be solved with one of the gases law. This law establishes that the pressure of the gas is directly proportional to its temperature: If we increase the temperature, the pressure will increase.
In this case, we decrease the temperature, so its pressure will be lower.
P₁ / T₁ = P₂ / T₂
We convert T° to Absolutes Values
27°C + 273 = 300 K
-173°C + 273 = 100 K
300 kPa / 300 K = P₂ / 100 K
(300 kPa / 300 K) . 100K = P₂
P₂ = 100 kPa

How do you know if an element is reactive or not?
The reactivity of an element depends upon the number of valence electrons, i.e., the electrons present in the outermost shell.
The number of electrons withinside the outermost shell of an atom determines its reactivity. Noble gases have low reactivity due to the fact they've complete electron shells. Halogens are extraordinarily reactive due to the fact they with ease advantage an electron to fill their outermost shell. Non-reactive metal atoms have whole outer shells and therefore do now no longer generally tend to lose, advantage, or percentage electrons. So, all factors having a crammed outermost shell are non-reactive. They also are referred to as noble gases. An element's reactivity is decided via way of means of the number of protons determined in an atom of the element.

Reactions that are reversible have the ability to move both forward and backward. Reactants change into products in a reversible reaction, but products can also change back into reactants.
In actuality, the opposing reaction as well as the forward reaction will occur simultaneously. In some chemical reactions, the reaction's products might combine to form the reactants' original form. Reversible reactions are what they are referred to as. To illustrate them, use the formula: A + B C + D. Only in one direction can irreversible chemical reactions take place. Reactants can transform into products, while products cannot transform back into reactants. Chemical reactions that can be reversed can happen both ways. The products can change back into the reactants, and the reactants can change back into the products.

A blend of dyes called a universal indicator gradually changes color throughout a pH range of 4 to 14. The color serves as a direct indicator of pH.
Thymol blue, methyl red, bromothymol blue, and phenolphthalein are the primary ingredients of a universal indicator in the form of a solution. Colors ranging from yellow to red denote an acidic solution, whereas colors ranging from blue to violet denote an alkaline solution and green denotes a neutral solution. Substances called indicators are those whose solutions change color as the pH changes. We refer to these as acid-base indicators.
