Q=hc A (Ts-Ta)
q = heat transfered per unit time
A= heat transfer area of the surface
hc= convective heat transfer coefficient of the process
Ts= temperature of the surface
Ta= temperature of the air
Ionic compounds are those compounds which are made up of ions. These ions can exist as positive or negative ions. Those ions which has tendency to lose electrons are said to be cations (positive ions) such as metals and those ions which has tendency to gain electrons are said to be anions (negative ions) such as non-metals.
The formula for ionic compounds are given as:
First, the symbols of the cation and anion should be identified. After that, charge on the cation and anion should be identified. Write the chemical formula with the help of drop and swap method.
Now,
The chemical symbols for Aluminium is 
and for chlorine is 
.
The charge on is +3 and on is -1, neglect the positive and negative signs and by using drop and swap method i.e. the charge on the aluminium will go as a subscript of the chlorine and the charge on the chlorine will go as a subscript of the aluminium which is shown in the image.
Thus, the chemical formula between and is 
.
Aluminum's outer electron in 3p-orbital is slightly further from the nucleus and protected by 3s-orbital. This causes it to need less energy. Magnesium's outer electron is closer and not protected by an outer orbital.
Hope This Helps and Ged Bless!
Answer:
SrCl2 + 2AgNO3 ----> Sr(NO3)2 + 2AgCl (solid)
Explanation:
SrCl2 + 2AgNO3 ----> Sr(NO3)2 + 2AgCl (solid)
Answer:
The mechanism is in the attached file. The reaction intermediates are the following: C4H8O, C4H9O
Explanation:
Terbutanol is a tertiary alcohol. It is one of the four isomers of butanol. It is a transparent liquid (or a colorless solid, depending on the temperature), with an odor similar to camphor. It is very soluble in water and ethanol.
The scheme shows a protonation of the double bond and the nucleophilic attack of the water to the carbocation, then it loses a proton and the terbutanol is formed.
