2.
The reason why is because there are 2 available electron spots on the orbital for the oxygen atom. Hydrogen atoms have one proton and one electron, thus, in order to fill the oxygen atom orbital to a full outer shell, a maximum of 2 atoms could bond with the oxygen atoms.
6 electrons (oxygen)+ 1 electron (hydrogen)+ 1 electron (hydrogen)= 8
1. take 20 * 0.5 to get 10 m/s
2. 0.8/0.4 = 2 Hz
Answer: The "equation" here is vinegar + baking soda = carbon dioxide. The reactants are vinegar and baking soda. The products are carbon dioxide.
Explanation: The reactants are the "ingredients," or the two or more substances you mix in order to form the product, the ending result. In this situation, you mixed vinegar and baking soda, so those are the reactants. You ended up making CO2, the product.
Mathematics and science are formal and exact sciences that are based on logic.
<h3>What is math and science?</h3>
Mathematics is an exact science that studies the properties and relationships between entities through geometric figures and arithmetic with numbers. Mathematics then looks for common patterns that could end up leading to a theory and, if it is verifiable and true, end up being a law, such as the Pythagorean law for example.
In terms of science, it is the comparable knowledge that has been studied, explained, and has helped predict social and natural phenomena in our universe over time. This has been done and verified through the scientific method, making it then a verifiable and true logic.
Therefore, we can confirm that mathematics and science are formal and exact sciences that are based on logic.
