Answer and explanation:

1. To increases the accuracy of the measurement, the person should try to make sure the ruler is parallel to the object they are measuring. If they measure the object with the ruler not being parallel the measurement will end up larger then expected. To increase the precision the person must measure with the ruler in the same position each time.

2. A situation in which a set of measurements are precise but not accurate could be if a student measured an object at an incorrect angle many times, like the inaccurate measuring in the image above. All of the measurements would be inaccurate, but since they were all measured inaccuratly the same way, they will be precise.

3. An objects mass is defined as being the amount of matter in said object. An objects weight is defined as being the force exerted on an object by gravity. Although the man would weigh less on the Moon because there is less gravity, he still would not fit in his clothes because his mass has not changed.

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.
