Answer: Matter cannot be created or destroyed
Explanation: Balanced equations are set equations we cannot change one element or compound in the equation without changing the entire equation. So balanced equation show the conservation of mass because while other substances may be formed from the synthesis or decomposition of compounds new elements are never introduced and are not created out of thin air :)
I think answer should be d. Please give me brainlest let me know if it’s correct or not okay thanks bye
Answer:
is it some kind of code??...........
Answer:
Distance between the carbon atom = 491 pm
Explanation:
Given:
1 pm = 1 × 10⁻¹² m
Distance between the carbon atom = 2.81 × 10⁻⁸ cm
Find:
Distance in picometers
Computation:
Distance between the carbon atom = 2.81 × 10⁻⁸ cm = 491 X 10⁻¹² m
Distance between the carbon atom = 491 pm
Hydrogen bonding is an attractive force between a hydrogen atom attached to a electronegative element
