Answer:
A
Explanation:
A common example of heterogeneous catalysis is the hydrogenation reaction of simple alkenes. The conversion of ethene (C2H4) to ethane (C2H6) can be performed with hydrogen gas in the presence of a metal catalyst such as palladium (“Conversion of Ethene to Ethane with Hydrogen and a Metal Catalyst”).
Answer:
Condensation 212F or 100C, Freezing 32F or 0C
Explanation:
Condensation 212 degrees Fahrenheit or 100 degrees Celsius.
Freezing point 32 degrees Fahrenheit or 0 degrees Celsius.
Answer:
it is nanometers the third one

A) molar mass H₂ = 2.0 g/mol
m = n * mm
m = 15.0 * 2.0
m = 30.0 g of H₂
_________________________
b) molar mass N₂ = 28.0 g/mol
m = n * mm
m = 3.5 * 28.0
m = 98.0 g of N₂
____________________________
c) molar mass of NaOH = 40.0 g/mol
m = n * mm
m = 2.69 * 40.0
m = 107.6 g of NaOH

<h2>Hey there!</h2>
<h3>The reaction given is called Decomposition reaction. </h3>
<h2>Explanation:</h2>
<h3>Here we can see that Magnesium Carbonate (MgCO3) is heated and as a result it has given two compounds which are Magnesium Oxide(MgO) and Carbon Dioxide (CO2).</h3>
<h3>Decomposition reaction:</h3>
- A reaction in which a chemical compound breaks into simpler parts in when heat is applied to it.
<h3>So,we concluded that the reaction given above is a Decomposition reaction. </h3>
