Which of the following is not true about the law of conservation of mass? a) nothing is created. b) the same number of atoms are in both the products and the reactants. c) new atoms are created when a new substance is formed. d) nothing is destroyed.

C) New atoms are created when a new substance is formed.

Explanation:

The mass conservation law was created by Antoine Lavoisier states that "in nature, nothing is lost, nothing is created and everything is transformed". This law stated that within a system where a chemical reaction occurs, the mass becomes a constant quantity, that is, the mass at the beginning of the reaction must be the same at the end of the reaction. This is because the number of atoms present in the reagents must be exactly the same as the number of atoms present in the product.

With that, we can affirm that the law of conservation of masses, affirm that in nature nothing is created, nothing is destroyed and the same number of atoms is in the products and in the reagents. However, this law denies that new atoms are created when a new substance is formed.

wild parsnip is a perennial plant which reproduces rapidly in areas which have no sign of agricultural activity such roadside or at no tillage open areas. it's considered invasive because it can inhibit the growth of another plant  and its reproduction is fast. there are several harmful effects of this invasive plant although its taproot is edible since it is a member of the carrot family. wild parsnips can cause skin blistering when in contact because of the chemicals it contains, second it inhibits the growth of other plants, it will restrict the growth of animals when eaten and lastly, it drives away natural pollinators like bees.
