You are watching: A nitride ion has 7 protons, 8 neutrons, and 10 electrons. what is the overall charge on this ion?
There are 10 electrons. It means the charge is "-10"There space 7 protons. It method the charge is "+7"Add both the them:+7 - 10 = -3Therefore the in its entirety charge ~ above this ion is -3.
This is a calorimtetry excersie whereby you use the formula
Q = C . M . ΔT
We only have actually 2 data native here, C and ΔT (from the solution)
C → 3.97 J/g°C
ΔT → 2.3°C
We determine the solution"s mass by density:
1.03 g/mL = systems mass / systems volume
We assume the HCl as the solution volume → 100 mL
1.03 g/mL . 100 mL = 103 g → solution"s mass
We replace data: Q = 103 g . 3.97 J/g°C . 2.3°C → 940.4 J
t-Butyl bromide (2-bromo-2-methylpropane) deserve to be ready by simply taking t-butyl alcohol and shaking it with an aqueous soluti
This is an instance of
Conversion that t-butyl alcohol come t-butyl bromide proceeds through
In the very first step, -OH group in t-butyl alcohol gets protonated.
In the second step, secure tertiary carbocation (t-butyl cation) is developed by removal of
In the 3rd step, bromide ion assaults to t-butyl cation and also produces t-butyl bromide.
Reaction mechanism has actually been shown below.

Given n2 (g) + 3 h2 (g) 2 nh3 (g), which script will enable you to ultimately reach an equilibrium mixture including these chem
The just scenario thatwill permit you to with an equilibrium mixture including these chemistry is toplace NH3 right into a sealed vessel. This reaction needs pressures in between 2100,3600 psi, and also temperatures between 300 and 550 level Celsius. With this giventemperature and pressure, the ammonia normally decomposes into nitrogen andhydrogen gas at the same rate. When this happen, the concentrations of thesechemicals become continuous and the mechanism is claimed to be in ~ equilibrium.
