What happens when you add hydrochloric acid to sodium carbonate?
Acid carbonate reactionProducts : carbon dioxide gas, water and salt sodium chlorideCarbon dioxide gas released as effervescence or bubbles, test for its presence using calcium hydroxide, slaked lime, by bubbling it into limewater to produce a chalky white precipitate of calcium carbonate.
What is the chemical formula of francium hydroxide?
Francium is an alkai metal and the usual oxidation state is 1+. Consequently, the chemical formula will be FrOH.
What is the formula of bicarbonate?
( HCO3 )-1
What is the chemical equation for barium reacts with water to form barium hydroxide and hydrogen?
Barium is alkaline earth metal ,having low standard reduction potential value. Thus it can displace hydrogen from water to form barium hydroxide with the evolution of hydrogen gas.Ba + 2H₂O——-> Ba(OH)₂ + H₂
Why sodium carbonate does not decompose on normal heating?
we can start from the basic conception of heat stability of ionic compounds, it mainly depends on the lattice enthalpy(energy required to break 1 mole of a compound in positive and negative ions). for high lattice enthalpy in a compound it becomes hard to break the bonds between negative and positive ions.Now amount of lattice enthalpy in the stated case will depend on the following factors of positive ion, as the negative ion is the same. 1)size of the ion 2)polarisation 3)electropositivity1) Na+ in Na2CO3 is smaller that Zn2+ in ZnCO3,so the negatively charged ion can attract the positively charged nucleus in the centre of positive ion more powerfully in Na than Zn.2) from fazans law we know existence of d-orbitals in (n-1) shell and high charge density accelerates the polarization in an ionic molecule.for Zn,we can find d-orbitals and higher charge density(+2 > +1|) than Na. so the molecule achieves a bit covalent properties which lessen its heat stabiltity.3)from the sreies of electropositive elements, we find Na>>Zn in terms of reactivity and thus Na compounds are much more stable than those of Zn.also for greater electropositivity, Na is attarcted much by carbonate than Zn increasing its lattice enthalpy.Thats why Na2CO3 is heat-stable but ZNCO3 is not.
What are the names for these formulas?
V(HCO3)4 vanadium (IV) bicarbonate FrClO3 francium chlorate GaP gallium phosphide Te(CN)2 tellurium cyanide S2O3 disulfur trioxide Cd(NO2)2 cadmium nitrite AgH silver hydride PO3 phosphorous trioxide Cr(HSO4)2 chromium (II) bisulfate
What is the formula for strontium phosphide? How is it determined?
First, find the elements that make up the compound in the periodic table: strontium is an alkaline earth metal in Group 2 (2nd column) and phosphorus is in Group 15. Strontium will form an ion with a +2 charge and phosphorus will form an ion with a -3 charge. Sr2+ and P3-A quick way to determine the formula is to ‘criss cross’ the charges: the charge on the strontium ion becomes the subscript on the phosphorus, and the (absolute value of) the charge on the phosphorus ion becomes the subscript on the strontium:Sr3P2
Balancing equations and net ionic equation?
Predict the products and write the balanced equations involved and the net ionic equations. (Show solutions/cancellation of cancellation of spectator ions). 1. Lead (II) acetate + potassium iodide 2. Sodium bicarbonate + bromic acid 3. Ammonium sulfate + barium phosphate 4. Sodium dihydrogen phospate + sodium hydroxide 5. Nickel chloride + francium sulfide
What are the most important uses of neutralization?
For pH control, popular chemicals include calcium carbonate, calcium oxide, magnesium hydroxide, and sodium bicarbonate. The selection of an appropriate neutralization chemical depends on the particular application. There are many uses of neutralization reactions that are acid-alkali reactions.
