1. Given the following equation: N2 (g) + 3 H2 (g) ↔ 2NH3 (g) ΔH = -92 kJ/mol
a. this reaction is exothermic as ΔH is -ve
b. the equilibrium will shift 2 the left if nitrogen gas is removed
c. the equilibrium shift 2 the right if the temperature is lowered
d. the equilibrium shift 2 the left if ammonia (NH3) is added
e. principle of thermodynamic potential or Gibbs energy is used to answer B-D
Answer:
A location that is humid, would most likely support a marsh ecosystem.
Explanation:
The Florida Everglades are an example of a marsh :)
"Marshes are a type of wetland ecosystem where water covers the ground for long periods of time. Marshes are dominated by herbaceous plants, such as grasses, reeds, and sedges."
When you cook food like eggs, this is a chemical change. Agree.
The runny egg turns into a solid. One type of matter must be changing into another type
When you cook food like potatoes, this is a chemical change. Agree.
Boiling potatoes causes changes in the structure of the starch. Higher heat as in baking, roasting, or frying causes the development of a harder crust on the potato. This suggests that chemical changes have taken place.
When a candle burns, the wick of the candle and wax turn into nothing. Disagree.
The <em>Law of Conservation of Mass</em> says that <em>you can’t turn matter into nothing</em>. What must be happening is that the wick and the wax are changing into other substances that we can’t see, such as colourless gases of carbon dioxide and water vapour.
1 is the answer. Both are made up of different particles. Same Letters of the periodic just not built the same ? (CO & CO2)& they are both odorless & colorless
