Answer:
carbon dioxideis the product
potassium + water is the product
Answer:
16.7%
Explanation:
40 ml of salt water + 200 ml of solution = 240 ml
40/240 = 4/24 = 1/6=16.7%
Define ionization energy and explain why the second aisle and ionization energy of the element is higher than its ionization energy
The energy needed to remove one or more electrons from a neutral atom to form a positively charged ion is a physical property that influences the chemical behavior of the atom. By definition, the first ionization energy of an element is the energy needed to remove the outermost, or highest energy, electron from a neutral atom in the gas phase.
The process by which the first ionization energy of hydrogen is measured would be represented by the following equation.
H(g) -----> H+(g) + e- deltaHo = -1312.0 kJ/mol
The answer is 1. chemical change.
That is when one substance changes into one or more new substances, it has exhibited a chemical change.
A Chemical change is a change that takes places when a substance changes its composition by forming one or more new substances. As here also, one substance is changing into one or more new substance, thus it exhibits a chemical change.
Nonene. Since it has c-c double bonds, we can be sure that its an alkene. To know its name, we can deduce from the number of carbon atoms ie 9.
