pychu [463]

<span><span>N2</span><span>O5</span></span>

Explanation! 

When given %, assume you have 100 g of the substance. Find moles, divide by lowest count. In this case you'll end up with

<span><span>25.92 g N<span>14.01 g N/mol N</span></span>=1.850 mol N</span>

<span><span>74.07 g O<span>16.00 g O/mol O</span></span>=4.629 mol O</span>

The ratio between these is <span>2.502 mol O/mol N</span>, which corresponds closely with <span><span>N2</span><span>O5</span></span>.

3.turn up the heat setting

Explanation:

A chemical reaction can be defined as a chemical process which typically involves the transformation or rearrangement of the atomic, ionic or molecular structure of an element through the breakdown and formation of chemical bonds to produce a new compound or substance.

Some of the laboratory apparatus (equipment) used for conducting a chemical reaction are conical flask, Bunsen burner, beaker, tongs, crucible, round bottom flask etc.

When heating a solution to boiling on a hot plate, start by starting and stabilizing the stir function. Then, turn the heat to a medium heat to start. If necessary, turn up the heat setting after waiting about ten minutes without seeing boiling.

The safety precautions that must be taken when heating a solution to boiling on a hot plate;

I. A proper inspection of the round bottom flask for cracks, irregularities or any imperfection.

II. Ensure you avoid heating the flask while it is closed.

III. When suspending the flask on a hot plate, you should ensure that you use a clamp for stability.

How many significant figures are needed in the answer when 1.31m is multiplied by 6.5 m​
dmitriy555 [2]

Answer:

two

Explanation:

The number of significant figures needed in the answer is 2.

This is because when finding the products of two numbers, the result is as accurate as the least number of significant figures of the numbers being multiplied.

Here the numbers being multiplied are;

 1.31m

 6.5m

        1.31m has 3 significant figures

          6.5m has 2 significant figures.

So, the product will have 2 significant figures
