Explanation:
edge 2022
The inside of a basketball has a pressure of 0.476 atm at 25.0°C. The pressure inside the ball if the temperature is decreased to 20.0°C is 0.484 atm.
What do you mean by the pressure ?The term pressure is defined as the amount of force applied perpendicular to the surface of an object per unit area. The symbol for it is "p" or P.
There are two basic types of pressure are absolute and gauge - distinguished by what pressure they are compared to, which is called the reference pressure.
Given:
P1 = 0.476 atm
T1 = 25.0°C = 298K
P2 = ?
T2 = 20.0°C = 293 K
P1T1 = P2T2
By putting these values in above equation and we get,
P2 = P1T1/ T2
= 0.476 ×298 / 293
= 0.484 atm
Thus, the pressure inside the ball if the temperature is decreased to 20.0°C is 0.484 atm.

Lewis structure of Hydroxide ion and it's formal charge
Answer:
Hopefully this was helpful!
In this structure, Oxygen (O) is the central atom, and it is bonded to one Hydrogen (H) atom. Oxygen also has two lone pairs of electrons.
To calculate the formal charge, we need to determine the valence electrons of each atom and compare them to the number of electrons assigned to the atom in the Lewis structure.
For Oxygen (O):
Valence electrons = 6
Number of lone pairs = 2
Number of bonding electrons = 2 (from the bond with Hydrogen)
Formal charge = Valence electrons - Lone pairs - Number of bonding electrons
= 6 - 2 - 2
= 2 - 2
= 0
For Hydrogen (H):
Valence electrons = 1
Number of bonding electrons = 2 (from the bond with Oxygen)
Formal charge = Valence electrons - Number of bonding electrons
= 1 - 2
= -1
Therefore, the formal charge of Oxygen in the hydroxide ion (OH-) is 0, and the formal charge of Hydrogen is -1.

A 35.3 g of element M is reacted with nitrogen to produce 43.5 g of compound M3N2 What is (i) the molar mass of the element and (ii) name of the element?
This problem is providing us with the mass of an unknown element which produces 43.5 g of M3N2. Thus, its name and molar mass are required and found to be 4.02 g/mol and calcium nitride after the following:
Stoichiometry.In chemistry, stoichiometry is a tool used for the calculation of masses or moles involved in chemical reactions, by the utilization of molar masses and mole ratios based on proportional factors.
In such a way, for the given reaction, one can use the formulas to write the following balanced chemical equation:
[tex]3M+N_2\rightarrow M_3N_2[/tex]
Where there is a 3:1 mole ratio of the metal to the product, which means we can use the following stoichiometric setup:
[tex]35.3gM*\frac{1molM}{x}*\frac{1molM_3N_2}{3molM} *\frac{(3x+14.01*2)gM_3N_2}{1molM_3N_2}=43.5gM_3N_2[/tex]
Now, by using the numbers only, one will be able to calculate x as the atomic mass of the element M in g/mol:
[tex]35.3*\frac{1}{x}*\frac{1}{3} *\frac{3x+14.01*2}{1}=43.5\\\\\frac{105.9x+989.106}{3x}=43.5\\ \\105.9x+989.106=130.5x\\\\989.106=130.5x-105.9x\\\\x=\frac{989.106}{130.5-105.9} =40.2g/mol[/tex]
Which matches with the molar mass of calcium. Moreover, we find its name as calcium nitride.
