I believe the answer is 3 - He hypothesized that all substances can be broken down into a smallest part called the atom.
Answer:
Explanation:
In an anion, there are more electrons than protons, giving the anion a positive charge.
In nonmetal atoms, the number of electrons and protons are the same and there is a positive charge.
The statement means that there’s too much water in relation to the orange concentrate.
So next time he should add less water/more juice.
By crushing a solid into a powder you increase the reaction rate (the chemical reaction rate). By crushing into a powder, you are increasing the surface area, increasing the exposure to the chemical reaction. The smaller the particles, the faster the chemical reaction that will take place. Think about an ice cube put in a pot of boiling water. The whole ice cube will take longer to melt than if you first crushed that ice cube into small pieces. Small pieces of ice put into boiling water would melt very quickly.
Hope this helps!! :)
During all chemical reactions, the mass of the products is never equal to the mass of the reactants.
- FALSE
Mass is sometimes lost in chemical reactions.
- FALSE
The Law of Conservation of Mass states that mass is not conserved.
- FALSE
