Answer:

Add 1 drops of a liquid sample or about 25 mg of a solid sample to 0.5 mL of distilled or deionized water in a test tube. Tap the tube with your finger to mix or stir gently with a glass stirring rod. Record the sample as soluble or insoluble. If the unknown is water-soluble, test the solution with pH paper.

Agregue 1 gota de una muestra líquida o aproximadamente 25 mg de una muestra sólida a 0.5 mL de agua destilada o desionizada en un tubo de ensayo. Golpee el tubo con el dedo para mezclar o revuelva suavemente con una varilla de vidrio para agitar. Registre la muestra como soluble o insoluble. Si lo desconocido es soluble en agua, pruebe la solución con papel de pH.

Hello, guys. Can someone please explain the meaning of the poem "To Keep One's Treasure Protected"
netineya [11]

Answer:

This poem talks about the fear of taking out the good in us.

Explanation:

The poem <em>"To Keep One’s Treasure Protected"</em> written by Stephen Dobyns begins by talking about the wonders that are hidden inside, such as the flame inside the coal, or a diamond hidden in the dark.

Then transfer this comparison to the human being. He asks himself: <em>"But what would be the coal’s choice if coal could be said to choose?". </em>

Human beings have the option of always bringing out the good that is in us, the problem is that we mostly do not.

It mentions some examples:

<em>"to see a man slip </em>

<em>to the sidewalk without going to help, to know </em>

<em>a song and not sing it, to watch the hungry </em>

<em>get hungrier, the defeated continue their steady </em>

<em>collapse. " </em>

Finally, the author urges us to change this, and to share with the world all the good we have.
