Answer:

Fourth Stroke.

Explanation:

There are four strokes in a car engine

a) Intake stroke: In this stroke the air and fuel is being pumped into the compressor from intake valve.

b) compression stroke: The piston moves upward and the fuel air mixture undergoes compression.

c)combustion stroke: The spark plug generates a spark and the fuel undergoes combustion. The energy produced push the piston backwards or downwards.

d) Exhaust stroke: the exhaust gases like carbon dioxide , water, carbon monoxide etc are forced up by the piston.

This is an incomplete question, here is a complete question.

Manganese commonly occurs in nature as a mineral. The extraction of manganese from the carbonite mineral rhodochrosite, involves a two-step process. In the first step, manganese (II) carbonate and oxygen react to form manganese (IV) oxide and carbon dioxide:

$2MnCO_3(s)+O_2(g)\rightarrow 2MnO_2(s)+2CO_2(g)$

In the second step, manganese (IV) oxide and aluminum react to form manganese and aluminum oxide:

$3MnO_2(s)+4Al(s)\rightarrow 3Mn(s)+2Al_2O_3(s)$

Write the net chemical equation for the production of manganese from manganese (II) carbonate, oxygen and aluminum. Be sure your equation is balanced.

Answer : The net chemical equation for the production of manganese is:

$6MnCO_3(s)+3O_2(g)+8Al(s)\rightarrow 6CO_2(g)+6Mn(s)+4Al_2O_3(s)$
