A: there is no unit. b: it doesn't present the temperature and pressure
Answer:
weather- rain, hail, snow, sunny, dry, etc.
climate- warm, cold, humid, dry, etc.
Explanation:
The difference if weather and climate is that climate is the way the temperature is, whether it's warm, cold, humid, dry. While weather is the state of the atmosphere at a place and time as regards heat, dryness, sunshine, wind, rain, etc.
Answer:
1. The balanced thermochemical equation for the reaction is;
2C4H10 (g) + 13O2 (g) -----------> 8CO2 (g) + 10H20 (g)
2. Heat when 200g of butane is burned is 9925.65 kJ of heat
Explanation:
2 moles of butane reacts with oxygen in excess to produce carbon iv oxide and water
If 1 mole releases 2877kJ of heat
2 moles will release (2 * 2877kJ) of heat
= 5754 kJ of heat.
The mass of butane used is 200g and converting it to moles we have;
n = mass / molar mass
molar mass of butane = (12 *4 + 1 *10) = 58 g/mol
So therefore n = 200 g/ 58 g/mol
n= 3.45 moles of butane.
If 1 mole of buatne releases 2877 kJ of heat
3.45 moles will release ( 3.45 * 2877 kJ ) of heat
= 9925.65 kJ of heat
9925.65 kJ of heat is released when 200 g of butane is burned.
Answer:
If those values are in terms of mass, weight or velocity
Kinetic energy will be in the order 180 » 120 » 105
