Balanced equation:
![2 \ Al + 6 \ HCl \to 2 \ AlCl_3 + 3 \ H_2](https://tex.z-dn.net/?f=2%20%5C%20Al%20%2B%206%20%5C%20HCl%20%5Cto%202%20%5C%20AlCl_3%20%2B%203%20%5C%20H_2)
2 moles of Al react with 6 moles of HCl. 2 moles of AlCl₃ and 3 moles of H₂ are produced.
The answer is C.
Answer;
B. crepuscular activity
Explanation;
Crepuscular animals are those that are active primarily during twilight. This is distinguished from diurnal and nocturnal behavior, where an animal is active during the hours of daylight or the hours of darkness, respectively.
The time of day an animal is active depends on a number of factors. Predators need to link their activities to times of day at which their prey is available, and prey try to avoid the times when their principal predators are at large.
Some creatures may adjust their activities depending on local competition.Therefore, for many varied reasons, crepuscular activity may best meet an animal's requirements by compromise.
An example of a heterogeneous catalyst is a catalytic converter. A catalytic converter is an emissions control device that converts toxic pollutants in exhaust gas to less toxic pollutants by catalyzing a redox reaction (oxydation or reduction).
Well it depends how close the places are to the edges of tectonic plates. Also the damage caused from the Earthquakes has to do with how sturdy the buildings are and whether they were built to withhold such strong forces.
Autotrophs are organisms that make their own food. Example: plants
