The Law of Conservation of Mass states that matter is not created nor destroyed.
Based on this, we can use some addition to find the answer.
3.00 + 1.40 = 4.40 g
Hope this helps :)
Answer:
8×10^(-3) mol/L
Explanation:
The formula for finding the hydrogen ion concentration is...
[H⁺] = 10^-ph
[H⁺] = 10^(-2.1)
[H⁺] = 0.00794...mol/L = 8×10^(-3) mol/L
The answer is to 1 significant digit because the pH has one decimal place.
They have a low boiling point because of weak intermolecular forces. They
Explanation:
Covalent compounds are compounds that are known to have weak intermolecular forces and hence low boiling point.
Covalent bonds are bond formed between two or more atoms having zero or very small electronegativity difference. Such bonds exists between molecules of non-metals.
Here are some properties of covalent bonds;
- They are gases or volatile liquids or low melting point solids
- Most of them are insoluble in polar solvents or water but they are generally soluble in non-polar organic solvents.
- They are mainly non-conductors.
