The model below shows the equation that represents how hydrogen and oxygen combine to form water. 2H2 + O2 → 2H2O 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 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 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 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. The total number of each type of atom is conserved in the equation.

noun

the practice of taking someone else's work or ideas and passing them off as one's own.

explanation:

the temperature of the gas, in k, not celsius.

answer : one can design an experiment using a liquid and an additive that can be added to the liquid and observe the chemical changes in the reaction species.

one would need a beaker which is filled with a known amount of the liquid in which thermometer is placed to measure the temperature changes; after addition of the additive to the liquid solution one can note down the temperature change and find whether the reaction is endothermic or exothermic in nature. by subtracting the initial temperature value with the final temperature one can find the temperature changes.

various combinations of liquid and additive can be used. liquid in this case can be a known quantity of water and additives can be epsom salt or without epsom salt the experiment can be conducted to notice the changes. water and ice, hydrogen peroxide and dry yeast, vinegar and baking soda,etc.
