Two moles of potassium react with 2 moles of water to form two moles of potassium hydroxide and 1 mole of hydrogen gas. The number of moles of hydrogen gas produced is half the number of moles of water and potassium that react together.
The molar mass of...
I would say B... ultraviolet rays cause sun burns
Answer:
The bond between Phosphorus and Chlorine in PCl3 is covalent as chlorine needs one electron and phosphorus has metallic character and easily donate electron
Answer:
NaHCO3 + HCl ——-> NaCl + H2O + CO2
Explanation:
A neutralization reaction is a chemical reaction between an alkali and an acid to give salt and water as the product.
In the case of carbonates and bicarbonates, an additional product is added. This additional product is carbon iv oxide.
Hence a neutralization reaction involving an acid and a carbonate or bicarbonate would yield water, carbon iv oxide and a salt as the product.
When brioschi reacts with hydrochloric acid, the products are sodium chloride, water and carbon iv oxide.
The equation of the reaction is shown below:
NaHCO3 + HCl ——> NaCl + H2O + CO2
<span>In a negative ion, or anion, electron(s) have been added to the atom. This means </span><span>the like charges within the electron cloud are now repelling each other more </span><span>than they were before. The proton count, however, has not changed. So, the </span><span>electron cloud, in response to the added electron(s) expands with that extra </span><span>repulsion. the negative Ions will have gained an electron fill an electron </span><span>shell while a positive Ion will have lost an electron in order to shed its </span><span>outermost shell, thereby making the atom smaller.
Hope this helps!
