Answer:
q = -176kJ
Explanation:
HCl and NH3 reacts as following to NH4Cl
HCl(g) + NH3(g)=========>NH4Cl(s) : ΔH = -176 KJ
Clearly,
ENERGY IS EVOLVED MEANING IT IS A EXOTHERMIC REACTION .
therefore, the value of heat evolved as q = -176kJ
Answer:
I think it's B
Explanation:
I think it is b because if the number is positive the zeroes will be on the left so you move the decimal to the right to get rid of the zeroes.

B. carbon sequestration
Explanation:
Carbon sequestration is a method that reduces carbon dioxide emissions by storing them for a long time.
- It is long term harvesting or sequestering of carbon dioxide from the atmosphere in order to avert air pollution and climatic change problems.
- Carbon sequestration is usually employed in the storage and capture of atmospheric carbon dioxide.
- The carbon dioxide can be sequestered using biologic or geologic means.
- Carbon dioxide gas is used to enhance oil recovery from geologic formations that have low permeability or those with low formation pressure to push out the oil.

Answer:
Aluminium is a highly reactive metal yet it is used to make utensils for cooking this is because aluminium reacts with oxygen present in air to form a thin layer of Aluminium oxide is oxide layer is very stable and prevent for the reaction of aluminium with oxygen
