Answer: Zinc nitride (Zn3N2) is an inorganic compound of zinc and nitrogen, usually obtained as (blue)grey crystals. It is a semiconductor. In pure form, it has the anti-bixbyite structure.
Chemical formula: Zn3N2
Space group: Ia-3, No. 206
EC Number: 215-207-3
Appearance: blue-gray cubic crystals
Explanation:
Answer:
False
Explanation:
As I like to think of it, equilibrium will shift either 'forwards' (to increase products) or 'backwards' (to increase reactants) to oppose any change in system;
If heat is added, the equilibrium will shift in the direction that reduces heat within the system;
In other words, it will shift in favour of the endothermic reaction, i.e. the reaction where heat is gained by the molecules/atoms and therefore taken out from the system;
If the 'forwards' reaction, producing NH₃, is exothermic (i.e. energy is released in the reaction), then the 'backwards' reaction is endothermic;
So the equilibrium will shift in this direction, which is the reaction of 2 NH₃ molecules producing N₂ and 3 H₂
Answer:
the character developed in an individual as a result of environmental influence.
Explanation:
Answer:- Volume of the 5.0 carat diamond is 
.
Solution:- It is a unit conversion problem. Need to convert carat to grams and then using grams and density the volume could easily be calculated.
We have 5.0 carat diamond and asked to calculate it's volume. Density of diamond is given as 
and 1 carat = 0.200 g. Let's do this step by step:
First step is the conversion of carat to grams:
= 1.0 g
In second step, grams are converted to volume using the given density as:
So, the volume of the 5.0 carat diamond is .
