How is a cation formed and which elements tend to become these in reactions?

Consider this equilibrium: H2 (g) + I2 (g) 2HI (g) Keq = 50.0. What is the Keq value when the reaction rewritten: 2HI (g) H2 (g) + I2 (g) Keq = ? A - 50.0 B 0.0200 C 25.0 D 50.0 E 0.04

Which is the first step in the dissolving process

Which reaction is an example of heterogeneous catalysis? Ethene gas reacts with hydrogen gas by using a nickel catalyst. Hydrogen peroxide decomposes by using an aqueous iodide ion catalyst. Formic acid decomposes by using an acidic catalyst.

Ali runs a paper chromatography experiment using the same ink, but three different solvents. Solvent A separates the components into three bands, solvent B separates it into two bands, and solvent C does not separate the ink.

If 3.0Ã-105 j of heat are added to the ice, what is the final temperature of the system?

Propane gas (C3H8) is combusted at a constant temperature and pressure. If 34.35L of propane react, what volume of oxygen is required? What volume of carbon dioxide is produced?

How is an organism related to a population?

The anion formed from an oxygen atom is called a (n) a. oxygen ion. c. carbon dioxide. b. oxide ion. d. nitrous oxide.

These values also increase from the bottom to the top of a group because the size of the atom decreases, resulting in a distance between the nucleus and the valence electron shell, which increases the attraction between the protons and electrons.

Given Mg (CO3) 2, CO2 and Cu3 (PO4) 2, provide the names for each of these molecules.
