Answer:
Sigma bonds: 10
Pi bonds: 4
Explanation:
The compound described must be CH2=CH-CO-CH≡CH. If we look at the compound closely, we will notice that there are 10 sigma bonds and 4 pi bonds.
There are three pi bonds between carbon atoms and one pi bond between a carbon and an oxygen atom (C=O). All these can easily be seen in the structure of the formula chosen in this answer.
Una mezcla homogenea es una mezcla solida, liquida o gaseosa que tiene las mismas proporciones de sus componentes en cualquier muestra dada. A la inversa, una mezcla heterogenea tiene componentes cuyas proporciones varian a lo largo de la muestra. "Homogeneo" y "heterogeneo" no son terminos absolutos sino que dependen del contexto y del tamano de la muestra. En quimica, una suspension homogenea de material significa que cuando se divide el volumen a la mitad, la misma cantidad de material se suspende en ambas mitades de la sustancia; sin embargo, podria ser posible ver las particulas bajo un microscopio. Un ejemplo de una mezcla homogenea es el aire.

b) Non-magnetic
c) No reaction with carbon disulphide.
d) i don't know sry
But i had to go through my 6th grade notes for this .____.
Answer:
Synthesis
Explanation:
Chemical equation:
3S + 2Fe → Fe₂S₃
The solid iron react with solid sulfur and form iron(III) sulfide. The reaction type is synthesis because,
Synthesis reaction:
It is the reaction in which two or more simple substance react to give one or more complex product.
A + B → AB
Other options are incorrect because,
In double displacement two compound exchange their ions and form new compounds.
AB + CD → AC +BD
In decomposition one reactant is break down into two or more product.
AB → A + B
In single replacement one elements replace the other element in compound.
AB + C → AC + B
