An El Nino often causes the temperature of the Pacific Ocean to increase several degrees which brings huge rainstorms to the coa

Firlakuza [10]

Scientists are able to detect an El Niño event and its effects on the climate through a variety of technological and natural sciences. One of these natural sciences is dendrochronology, or the study of tree rings. Dendrochronologists study the rings of a tree in order to understand climatic conditions during specific time periods. Thin rings often indicate drier seasons while fatter rings indicate rainy seasons. Depending on where the tree is, scientists can see past El Niño events in trees that exhibit signs of much rainier or drier seasons that normal.

There are two steps in the usual industrial preparation of acrylic acid, the immediate precursor of several useful plastics. In

kodGreya [7K]

Answer: The net chemical equation for the production of acrylic acid is given below.

Explanation:

We are given two intermediate equations:

Equation 1: $CaC_2(s)+2H_2O(g)\rightarrow C_2H_2(g)+Ca(OH)_2(s)$

Equation 2: $6C_2H_2(g)+3CO_2(g)+4H_2O(g)\rightarrow 5CH_2CHCO_2H(g)$

To get the net chemical equation for the formation of acrylic acid from calcium carbide, carbon dioxide and water, we multiply the first equation by a factor of '6'.

The equation becomes:

Equation 1: $6C_2H_2(g)+6Ca(OH)_2(s)$
