Explanation:
Answer:
Structure of the product has been shown below
Explanation:
- N atom in aniline acts as a nucleophile and carbonyl group of propanoic acid acts as an electrophilic center.
- A nucleophilic acyl substitution reaction occurs on mixing and heating mixture of aniline and propanoic acid.
- In this reaction an amide is formed.
- Reaction mechanism goes through addition-ellimination pathway at carbonyl center.
- Full reaction mechanism has been shown below.
Li2CO3 + 2HNO3 ----> 2LiNO3 + H2O + CO2
Answer:
Newton's first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force. This is normally taken as the definition of inertia.
Newton's second law says that when a constant force acts on a massive body, it causes it to accelerate, i.e., to change its velocity, at a constant rate. In the simplest case, a force applied to an object at rest causes it to accelerate in the direction of the force
His third law states that for every action (force) in nature there is an equal and opposite reaction. In other words, if object A exerts a force on object B, then object B also exerts an equal and opposite force on object A.
Inertia is the resistance of any physical object to any change in its velocity. This includes changes to the object's speed, or direction of motion. An aspect of this property is the tendency of objects to keep moving in a straight line at a constant speed, when no forces act upon them
I think it'd because of (4), the reactivity of gold atoms, or rather, it's unreactivity. Gold, unlike most metals, doesn't form an oxide layer when exposed to air (Which is why it's so valued in jewellery, the metal will never tarnish, only stay gold forever). This makes it weaker, and so it can be formed in to thinner sheets.
However, (3), the nature of bonds between gold atoms also allows for the metal to be flattened, as metallic bonds aren't amazingly strong, and allow for metals to bend. This is what makes pure metals so weak, and why we use alloys.
