I have to write a net ionic equation for nitric acid and calcium hydroxide and all the answers I’ve submitted have been rejected. If someone could explain how to create the equation that would be great.

Write your reactants as ions in solution, as well as your products as either ions or molecules. Then cancel out things that appear on either side of the reaction
So:
2HNO3 + Ca(OH)2 -> Ca(NO3)2 + 2H2O
becomes
2H+(aq) + 2NO3-(aq) + Ca2+(aq) + 2OH-(aq) -> Ca2+(aq) + 2NO3-(aq) + 2H2O(l)

As you can see, 2NO3- and Ca2+ appears on both sides of the equation, so we cancel them out, and they are excluded from the net ionic equation

Net ionic:
2H+ (aq) + 2OH- (aq) - 2H2O (l)

Hello, I am fifteen years old, and I have approximately five days to decide my future job.
I am wondering if there is any career in computer programming that provides extremely good money (400,000$+). Also could you please list some courses that I would have to take in order to achieve this.
Thank you for your time. Full points to the best answer. :)
Most programmers don’t make 6 figures (or barely make 6 figures, if they’ve been at it for a while). For that kind of money, you have to have some pretty good ideas, skills, and business sense. One possibility: creating a startup that get’s bought out by a bigger firm. A great deal of success can be had through independent efforts (think: Google, Facebook), but it’s also rather risky (you’re not likely to be the next Google, or Facebook). If you’re interested in a more corporate setting, upper management positions (senior design leads, etc.) probably make closer to the amounts you’re talking about. And any large software company will have plenty of upper management positions (though not easily attained, necessarily, without a lot of motivation and people skills, on top of programming skills).

The courses you take are almost irrelevant; if they have programming courses at your school you should definitely take them; but it’s more important that you have the desire to learn things on your own. You can learn a lot more about programming by just trying things out than by taking structured courses (experience is everything).

I think you have the wrong perspective here: don’t worry about money or courses or your career, even. Just try to find something you like doing, then afterwards try to figure out how you can make money doing it.

I use Dreamweaver in a way that I need the <s> command constantly. As far as I can tell, the only ways to make that line appear through the text is by manually coding it in or my using the dropdown menu. Those are both really inconvenient. Is there any way to add a strikethrough button to a toolbar menu? Alternatively, is there a keystroke that could do it for me?

Those tags are deprecated in HTML 4.0.1, meaning they may become obsolete in future versions of HTML. Use CSS to do that:

<style type="text/css">
.strike { text-decoration: line-through; }
</style>

Have you tried using the Redo Command to see if it would work. My editor has code snippets which are easily added when I need them. Must be the reason why I haven’t opened my DW in ages. :P

Actually, by default Dreamweaver does not use the traditional <b> and <i> HTML tags for bold and italic, respectively. Instead it uses <strong> and <em> (for emphasis). The latter tags are preferred as part of best practices, because they are better handled by screen readers used by visually impaired users. If you want to switch Dreamweaver back to using <b> and <i>, choose Edit > Preferences (Dreamweaver > Preferences), and in the General category of the Preferences dialog, deselect "Use <strong> and <em> in place of <b> and <i>."
