The correct options are these:
1. It will follow the law of conservation of mass.
2.The mass of products will be equal to the mass of the reactants.
The law of conservation of mass states that ' matter can neither be created nor destroyed. Thus, if a chemical equation is balanced, the mass of the reactant at the beginning of the reaction will be equal to the mass of the product after the reaction. This shows that the chemical reaction obeys the law of conservation of mass.
Answer:
A. an observation
Explanation:
Because by saying that the leaf is green that is an observation on the leaf to tell what color it is.
Have a nice day/night :)
Answer: Option (a) is the correct answer.
Explanation:
Non-metals are the species which in order to complete their octet readily gain an electron.
For example, fluorine is a non-metal with atomic number 9 and its electronic distribution is 2, 7.
Hence, to attain stability it readily accepts an electron from a donor atom.
Some characteristics of non-metals are as follows.
Non-metals do not conduct electricity.
Non-metals are brittle in nature and they have a rough surface.
Non-metals are not malleable or ductile.
Thus, we can conclude that non-metals do not conduct electricity is a characteristic of non-metals.
The correct option is this: EFFUSION BECAUSE THERE IS A MOVEMENT OF A GAS THROUGH A SMALL OPENING INTO A LARGER VOLUME.
Effusion refers to the movement of gas particles through a small hole. According to Graham's law, the effusion rate of a gas is inversely proportional to the square root of the mass of its particles.
