Q=mc\Delta T
Q= 40.5g x 0.900 J/g degree Celsius x 7.5
Q= 273.4 J.
Even if it is cooled , we use the same temperature as heating it.
Answer:
carbon dioxide is fixed or incorporated into organic molecules.
Explanation:
Carbon dioxide fixation is the conversion of inorganic carbon into organic carbon.
In photosynthesis CO2 is converted into glucose i.e inorganic carbon (CO2) is converted into organic molecule (glucose).
The type of reaction that is Mg +S→ MgS is a synthesis reaction
<u><em>Explanation</em></u>
Synthesis reaction as refers to as direct combination is a reaction in which two or more chemical species combine to form more complex product.
The reaction of Mg +S → MgS is a synthesis reaction because;
Mg combine with S to form a more complex product MgS
D all of these I’m about 99% sure
