Write a symbol equation for the reaction when copper carbonate is heated?
The thermal decomposition in this case is: CuCO3 -------------CuO + CO2
Why is calcium carbonate insoluable?
It is a very good question indeed! You see calcium chloride in which calcium is attached to two chlorine atoms is water soluble and vice versa sodium carbonate in which two sodium atoms are attached to one carbonate is soluble. In one to one proportion, calcium chloride molecule is insoluble. Now the answer for this question may go like this. In case of calcium chloride calcium gives one electron to each of chlorine atom. Now both chlorine atoms would have one negative charge. So both of them will repel each other and form the ions of calcium and two chlorine. Thus making them soluble. In case of sodium carbonate, two sodium atoms give electrons to carbonate. Now both sodium ions become positively charged and and would repel each other. So they would form ions along with carbonate. So sodium carbonate has become soluble. Now in case of calcium carbonate, calcium would like to give away 2 electrons but carbon becomes much electrically negative if it takes the electrons. So in this case no repelling force is there to help the metal, it surrenders and form sort of covalent bond and thus ions are not formed. So calcium carbonate is insoluble in water.
Name of formula Cu2C2O4?
copper (I) oxalate Always write formulas with lower case letters.
What is the normal phase of the element germanium?
the word phase also means its state so in that case germanium's normal phase or state is solid the word phase also means its state so in that case germanium's normal phase or state is solid the word phase also means its state so in that case germanium's normal phase or state is solid
What is the chemical equation for calcium hydrogen carbonate?
There cannot be a balanced chemical formula for just a compound of something. You need a reactant to produce a product in order to balance an equation. In this case, you can get a chemical formula by this chemical name: calcium hydrogen carbonate. Since calcium has a +2 charge and hydrogen carbonate has a -1 charge, you need two hydrogen carbonates for every one calcium ion. The chemical formula is: Ca(HCO3)2.
What do you mean by modes of propagation in the case of electromagnetic waves?
groundwaves line of sight skywaves
What is the hard protective outer case of an oyster?
The shell of an oyster is mostly made of calcium carbonate.
How do you find a mode if 2 numbers appear the same number of times?
There are two modes. The mode is the only measure of central tendency where you can have no mode (no number appears more than another), one mode, or several modes, such as in your case.

Are all unimodal distributions normal?
No. Normal distribution is a special case of distribution.
What is the process of transportation?
movement of objects from a point of origin to a point of departure using roads, rail , and pipeline modes in the case of land transport.

What is formula of 'Sodium II Hydrogen Carbonate'?
It would have to be Na(HCO3)2 But no such thing exists.This would require sodium to form a 2+ ion.It can only form a 1+ ion.The real formula for sodium hydrogen carbonate is NaHCO3 .This would be sodium I hydrogen carbonate, though the roman numeral is not needed in this case.

copper (I) oxalate Always write formulas with lower case letters.
What is the difference of a normal distribution and a stardard normal distribution?
The standard normal distribution is a special case of the normal distribution. The standard normal has mean 0 and variance 1.
