C, because the nervous system takes in information through our senses, processes the information and triggers reactions, such as making your muscles move or causing you to feel pain.

Answer: Hello, Though ice and snow are both made up of water, there is a difference between the two. Snow is nothing but the frozen atmospheric vapour which falls in winters on earth as light flakes whereas ice is simply frozen water.
Explanation:
Answer:
AlCl₃ + 3NaOH → 3NaCl + Al(OH)₃
Explanation:
Problem is to balance the given chemical equation:
Equation:
AlCl₃ + NaOH → NaClO₂ + Al(OH)₃
Balancing a chemical equation involves the conservation of atoms on both sides of the equation.
We can use a very simple mathematical method to balance the above equation;
aAlCl₃ + bNaOH → cNaCl + dAl(OH)₃
a, b, c and d are coefficients that will balance the equation:
Conserving Al: a = d
Cl: 3a = c
Na: b = c
O: b = 3d
H: b = 3d
Assume that a = 1;
c = 3
b = 3
d = 1
AlCl₃ + 3NaOH → 3NaCl + Al(OH)₃
O₂ in from of the NaClO₂ flouts the rule of chemical combination
Endeavour is the youngest shuttle in NASA's orbiter fleet, and was built as a replacement for Challenger. The shuttle flew 25 missions over the course of its spaceflying career, logging a total of 122,883,151 miles (197,761,261 km) on its odometer. Endeavour launched on its maiden flight, STS-49, on May 7, 1992.
