An exothermic reaction is a chemical reaction that releases energy by light or heat. It is the opposite of an endothermic reaction. im sorry i only could do one! but hope this helped!
Answer:
The relative humidity in Raleigh, NC
You can search it up online. Search up what is climate change and it will give you "the weather conditions prevailing in an area in general or over a long period." (On bing)
Explanation:
Can I have brainliest? It would help me out, if not thanks anyways! Hope this helped and have a nice day!
The mass change, or the mass defect, can be calculated by the formula that is very known to be associated with Albert Einstein.
E = Δmc²
where
E is the energy gained or released during the reaction
c is the speed of light equal to 3×10⁸ m/s
Δm is the mass change
(1.715×10³ kJ)(1,000 J/1 kJ) = Δm(3×10⁸ m/s)²
Δm = 1.91×10⁻¹¹ kg
You can use the formula: C = k - 273 to solve this problem. C stands for Celsius, and k stands for kelvin. Given the information that the Kelvin is 172k, then you can plug it into the equation and get C = (172) - 273. The correct melting point in C is -101°C. Hope this helped!
Answer:
3.193 mol
Explanation:
The reaction is
We use the stoichiometry in order to find the moles of nitrogen required.
The amount of nitrogen required is 3.193 mol to produce 9.58 mol of ammonia.
