Answer:
4 mol of lithium nitride would be produced
Explanation:
6Li + N2 → 2Li3N
This equation means that 6 mol of lithium are reacted with 1 mol of nitrogen to make, 2 mol of lithium nitride.
So this is the rule of three to find out, how many moles of lithium nitride are been made, from 12 mol of Li.
6 Li _____ 2 Li3N
12 Li ________ (12. 2) / 6 = 4 moles
Answer:
by providing an alternative pathway with a lower activation energy
Explanation:
Cataysts are the substances that neither consumed nor produced during a chemical reaction, but increase the rate of the reaction.
So, catalysts remain chemically unchnaged after the completion of the reaction.
For a reaction to occur, reactants molecule must collide and successful collisions lead to product formation.
A certain minimum amount of energy is required for successful collision. This minimum amounr of energy is called activation energy.
One way to increase speed of reaction is to provide energy to the reactants and other way to increase speed is to provide alternate pathway with lower activation energy.
Catalyst increases a rate of reaction by providing an alternate pathway with lower activation energy.
Therefore, the correct option is option b 'by providing an alternative pathway with a lower activation energy'
Answer:
From the name <em>Canis lupus</em>, one can find that the organism is a wolf. <em>Canis</em> is a genus meaning "dog". <em>Lupus</em> is the species meaning "wolf". So in short, <em>Canis Lupus</em> means "dog wolf".
One reason scientist use scientific names is to avoid confusion. For example, there are many species of bass, a fish, but there's only one kind of <em>Micropterus salmoides</em>, or a Largemouth bass for short.
