- Q1What is the law of conservation of mass?an object continues in its original conditiothe acceleration of an object depends on the size of the force acting on itis conserved when objects collideThe total mass of the product is always the same as the total mass of the reactants.30s
- Q2How can balancing a chemical reaction reflect the law of conservation of mass?The chemical equation bonds to the law of conservation of mass so that the matter can easily be destroyed.Every chemical equation bonds to the law of conservation of mass, which states that matter cannot be created or destroyed.30s
- Q3As a tree gets older, why does it not follow the law of conservation of mass?Including balanced chemical equations as a part of the planning and analysis of a scientific investigation is important because a balanced chemical equation is a clear, direct, and efficient way to represent the type of chemical reaction involved in the investigation.Hydrogen, Nitrogen, oxygen, florine, chlorine, bromine, and iodine all exist as diatomic molecules.Through photosynthesis the tree uses energy from the sun to convert carbon dioxide and water into glucose and oxygen. It uses the glucose to build the cells that allow it to grow. No matter is created or formed, in that no atoms are destroyed or created in the reaction.30s
- Q4Your classmates states that the law of conservation of mass is not being followed in the reaction of Mg(s) + 02(g) = MgO(s) because there is a loss of one atom of oxygen in the process. Is this true or falseTrueFalse30s
- Q5Why does the law of conservation of mass matter?It matters because it states that matter is not destroyed or created in a chemical reaction, it stays constant.It matters because it shows us that it can be destroyed in a chemical reaction. It doesn't stay the same.It matters just because it matters.30s
- Q6In a chemical equation with the law of conservation of mass included, what happens to the atoms?The atoms get created.The atoms get destroyed.The atoms stay the same.They atoms get rearranged.30s
- Q7Who founded the law of conservation of mass?Isaac NewtonWilliam RankineJulius Robert MayerAntoine Laurent Lavoisier30s
- Q8When was the law of conservation of mass discovered?177518671785179830s
- Q9In a chemical equation, is the mass always the same before and after when it is involed with the conservation of mass?NoYes30s
- Q10Why don't we call the law of conservation of mass just law of conservation?Scientists like to name things very long.It sounds too dumb.There are other items that are called law of conservation.It isn't scientific enough.30s
