What is isotopes and how to write chemical formula​

Chemistry
1 answer:
Anna [14]3 years ago
3 0

Answer:

Isotopes are the atom of an element that have different numbers of neutrons but have a similar number of protons and electrons. The difference in the number of neutrons between the various isotopes means that various isotopes have different masses.

A tank contains 115 miles of neon gas. It has a pressure of 57 atm at a temperature of 45 c. Calculate the volume of the tank.
Elena-2011 [213]

Answer:

Volume occupied by  Neon gas is 52.67 L

Explanation:

Using Ideal Gas Equation:

PV = nRT

where

P = pressure exerted by the gas = 57 atm

V = volume occupied = ?

n = number of moles = 115 moles

R = Ideal gas constant = 0.0821 L.atm/K.mol

(R value should be taken according to the units of Temperature,pressure, volume and mole)

T = Temperature = 45 + 273 = 318 K

(For temperature conversion from C to K add 273 to temperature:T + 273)

PV = nRT , So

V = \frac{nRT}{P}

Put values of T,P,n,R

V = \frac{115\times 0.0821\times 318}{57}

V = \frac{3002.39}{57}

V = 52.67 L

Volume occupied by 115 moles of Neon gas at 57 atm Pressure and 45 C temperature is 52.67 L

Consider the reaction, 2 d(g) + 3 e(g) + f(g) => 2 g(g) + h(g) when h is increasing at 0.64 mol/ls, how quickly is e decreasi
bekas [8.4K]
Answer is: 1,92 mol/L·s.
Chemical reaction: 2D(g) + 3E(g) + F(g) → <span>2G(g) + H(g). 
</span>H is increasing at 0,64 mol/L·<span>s.
From chemical reaction n(H) : n(E) = 1 : 3.
0,64 mol : n(E) = 1 : 3.
n(E) = 1,92 mol.
</span>E is decreasing at 1,92 mol/L·s.
