What is the Law of conservation of matter?

Matter is neither created nor destroyed.

Matter is neither created nor destroyed in an ordinary chemical reaction.

List 3 physical activities in which the human body engages in movement.Next:Determine which bones are involved in these movements.

Additionally, if you have a question, it is much better to put it in as a separate post in <Post a New Question> rather than attaching it to a previous question, where is more likely to be overlooked.

I hope this helps a little more.

Ah, the Law of Conservation of Matter, also known as the 'Don't Let Anything Escape the Party' law. It states that matter cannot be created or destroyed in a chemical reaction. Basically, it's like saying, "Hey, matter, you can't just disappear or magically appear out of nowhere. You've got to stick around and keep this shindig going!" So, next time you see some matter trying to make an excuse and escape, remind it of the Law of Conservation of Matter and tell it to stay put!

The Law of Conservation of Matter states that matter cannot be created or destroyed in a chemical reaction. In other words, the total mass of the reactants in a chemical reaction is equal to the total mass of the products. This law is a fundamental principle of chemistry and is based on the fact that atoms are neither created nor destroyed during a chemical reaction.

To understand the Law of Conservation of Matter, it is useful to consider a balanced chemical equation. A balanced equation indicates the relative number of each type of atom involved in a chemical reaction. Each element is represented by its chemical symbol, and the number in front of the symbol denotes the number of atoms of that element. For example, the balanced equation for the reaction between hydrogen (H2) and oxygen (O2) to form water (H2O) is:

2H2 + O2 → 2H2O

In this equation, there are two molecules of hydrogen gas (H2) reacting with one molecule of oxygen gas (O2) to produce two molecules of water (H2O). The Law of Conservation of Matter states that the total number of hydrogen and oxygen atoms before the reaction is equal to the total number after the reaction.

To apply the law, you can count the number of atoms of each element on both sides of the equation. If the numbers are the same, then the reaction is in accordance with the Law of Conservation of Matter. If the numbers are not the same, the equation needs to be balanced by adjusting the coefficients (numbers in front of the formulas) to ensure that the number of atoms on both sides of the equation is equal.

In summary, the Law of Conservation of Matter states that matter cannot be created or destroyed in a chemical reaction. It can be used to balance chemical equations and is a fundamental concept in chemistry.

It depends on how you define physical activities. It could range from running to typing to weight lifting or chewing gum. Depending on the activity, all bones could be involved in the movements.

Since this is not my area of expertise, I searched Google under the key words "bone movement" to get these possible sources:

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search.

I hope this helps. Thanks for asking.
