The answer is prokaryote :)
The answer is: first substance is base and second is acid.
Bases, for example solution of sodium hydroxide (NaOH) feels slipery.
Sodium hydroxide dissociation in water: NaOH(aq) → Na⁺(aq) + OH⁻(aq).
Ionic compounds are good good electricity and heat conductors, because ionic compounds have mobile ions (cations and anions) that are able to transfer electrical charge.
In second reaction, magnesium is oxidized from oxidation number 0 to +2 and hydrogen is reduced from +1 to 0 (hydrogen gas).
First we need to find the number of moles of both K and O reacted
K - 0.779 g / 39 g/mol
= 0.02 mol
the mass of O₂ reacted = 1.417 g - 0.779 g = 0.638 g
O₂ moles = 0.638 g / 32 g/mol
= 0.02 mol
the number of both K and O₂ moles reacted are equal
therefore stoichiometry of K to O₂ reacted are 1:1
then the formula of potassium superoxide is KO₂
So the atomic number is the same as protons, and electrons and to get neutrons by subtracting number of protons from atomic mass.
Answer:
Heat energy is the result of the movement of tiny particles called atoms, molecules or ions in solids, liquids and gases. Heat energy can be transferred from one object to another. The transfer or flow due to the difference in temperature between the two objects is called heat
