What is 5 times 5?
Asked Wed Aug 12, 4:07 PM
To find the answer, you multiply 5 by 5. Multiplication is like adding groups of things together. So, in this case, you're essentially counting how many sets of 5 there are.
So, 5 x 5 = 25. That's why multiplication is often represented with a symbol called the "product" or simply as "the answer".
What is the chemical formula for table salt?
Asked Tue Aug 11, 12:12 PM
Table salt is sodium chloride, and its chemical formula is NaCl.
This means each unit of table salt is made up of one sodium atom (Na) and one chlorine atom (Cl), bonded together through an ionic bond. Sodium loses an electron to become a positively charged ion (Na+), while chlorine gains that electron to become a negatively charged ion (Cl-). These opposite charges attract each other, forming the ionic compound we know as salt.
When dissolved in water, NaCl separates back into these Na+ and Cl- ions, which is why saltwater conducts electricity.
