Answer:
Metallic character refers to the level of reactivity of a metal. Non-metallic character relates to the tendency to accept electrons during chemical reactions. Metallic tendency increases going down a group. Non-metallic tendency increases going from left to right across the periodic table.
Explanation:
Answer:
Option D would be correct: The mass of the products is equal to the mass of the reactants
Explanation:
For example, in chemical reactions, <u>the mass of the chemical components before the reaction is equal to the mass of the components after the reaction</u>.
hope this helps :)
Answer:
Basically, a variable is any factor that can be controlled, changed, or measured in an experiment. It's anything that can be changed in the experiment.
Explanation:
Scientific experiments have several types of variables. The independent and dependent variables are the ones usually plotted on a chart or graph, but there are other types of variables you may encounter. The presence/absence of the chemical is the independent variable. The health of the (ex:)rat (whether it lives and can reproduce) is the dependent variable.
