Plz help :) The model below shows the equation that represents how hydrogen and oxygen combine to form water.
2H2 + O2 + 2H20

Read each statement below and select all that apply to the equation.

The number of atoms of oxygen in the reactants is different than the number of atoms of oxygen in the product.
The law of conservation of matter is not applied in this equation.
The mass of the reactants is equal to the mass of the products in the reaction.
The total number of each type of atom is conserved in the equation.

plasma - state of matter made up of electrically charged particles

the seeing the electronic configuration we can say that the element is fluorine.

fluorine is the most electronegative element in the periodic table.

but by only seeing the configuration we cannot say about its reactivity because we don't know if its configuration after excitation or by addition of electrons.

but if not then, it is the lightest halogen and exists as a highly toxic pale yellow diatomic gas at standard conditions. as the most electronegative element, it is extremely reactive: almost all other elements, including some noble gases, form compounds with fluorine.

gasoline is a mixture. it contains several different kinds of compounds that can be present in a variety of ratios.
