Nitrogen is a diatomic molecule in the VA family on the periodic table. Nitrogen has five valence electrons, so it needs three more valence electrons to complete its octet. A nitrogen atom can fill its octet by sharing three electrons with another nitrogen atom, forming three covalent bonds, a so-called triple bond.
The law of conservation of mass states that, for any closed system, the mass of the system must remain constant.
So, in other words, mass cannot be created nor destroyed.
In a burning log, the initial mass of the wood and the ashes that are left behind after it burns are different, which would seem to violate the law of conservation of mass.

NSAIDs can cause the kidney to retain salts and water, prompting a rise in blood pressure and potentially making medications to lower hypertension ineffective
Explanation:
In normotensive subjects neither blood pressure nor renal function is significant affected by selective COX-2 inhibitors or nonselective NSAIDs
