<h3>What is a word equation?</h3>
A word equation is one that is written in words rather than using the normal symbols of the elements that are involved. In this case we are asked to write the word equation for certain reactions and the states of matter of each of the terms in the reaction must be stated.
The word equations are as follows;
- sodium carbonate solution(aq) + silver nitrate solution(aq) ----> sodium nitrate(aq) + silver carbonate(aq)
- potassium carbonate solution(aq) + nitric acid (hydrogen nitrate) solution(aq) -----> potassium nitrate(aq) + water(l) + carbon dioxide
- barium nitrate solution (aq)+ potassium chromate solution(aq) -----> potassium nitrate (aq) + barium chromate (s)

<span>Jet streams are the major means of transport for weather systems. A jet stream is an area of strong winds ranging from 120-250 mph that can be thousands of miles long, a couple of hundred miles across and a few miles deep. Jet streams usually sit at the boundary between the troposphere and the stratosphere at a level called the tropopause. This means most jet streams are about 6-9 miles off the ground. Figure A is a cross section of a jet stream.

The dynamics of jet streams are actually quite complicated, so this is a very simplified version of what creates jets. The basic idea that drives jet formation is this: a strong horizontal temperature contrast, like the one between the North Pole and the equator, causes a dramatic increase in horizontal wind speed with height. Therefore, a jet stream forms directly over the center of the strongest area of horizontal temperature difference, or the front. As a general rule, a strong front has a jet stream directly above it that is parallel to it. Figure B shows that jet streams are positioned just below the tropopause (the red lines) and above the fronts, in this case, the boundaries between two circulation cells carrying air of different temperatures.
To find pH, use the following formula ---> pH= - log [H+]
so first we need to calculate the [H+] concentration using the OH concentration. to do this, we need to use this formula--> 1.0x10-14= [H+] X [OH-], so we solve for H+ and plug in
[H+]= 1.0X10-14/[OH-]---> 1.0 x 10-14/ 1.0 x 10-4= 1.0 x 10-10
now that we have the H+ concentration, we can solve of pH
pH= -log (1.0x10-10)= 10
