The name of OH^{-} ion is hydroxide.

Name of  PO^{3-}_{3} ion is phosphite.

Name of  PO^{3-}_{4} ion is phosphate.

Name of  NH^{+}_{4} ion is ammonia.

Name of  C_{2}H_{3}O_{2}^{-} ion is acetate.

Name of  C_{2}O_{4}^{-} ion is oxalate.

Thus, we can conclude that the symbols and names for the ions given correctly is OH-:hydroxide

Calculemos la formula empirica y molecular de carbonato de hierro Fe2(co3)3.Fe.38.3%C.12.3%.0.4 92% masa 292g
DENIUS [597]

Respuesta:

292 g / mol;

Por favor, consulte la explicación.

Explicación:

El número de átomos de cada elemento en el compuesto: Fe2 (co3) 3.

Fe = 2; C = 3; 0 = 3 * 3 = 9

Fe2 = 112 g / mol

C = 12 g / mol

O = 16 g /

Masa molecular = ((112 + (12 * 3) + (16 * 9)

= (112 + 36 + 144)

= 292 g / mol.

Total = 2 + 3 + 9 = 14

Fe2 = 112/292 * 100% = 38,356%

C = 36/292 * 100% = 12,328 * '

O = (16 * 9) / 292 * 100% = 49,32%

What type of reaction is : CaCo3+ HCl = CaCl2 + CO2 +H2O
Pavlova-9 [17]

Answer:

Double decomposition reaction

Explanation:

When hydrochloric acid reacts with any carbonates/hydrogen carbonates the products formed are metal chloride , water and carbon dioxide.Since HCl decomposes salts of weaker acids.

So the equation of the reaction between calcium carbonate and HCl is:

CaCO3+2HCl =CaCl2+H2O+CO2

This reaction is also known as double decomposition reaction.
