What is one way to make stored water safe?

Chemistry
1 answer:
Marianna [84]2 years ago
3 0

Even though you asked for ONE WAY, I found some other good ways.

1. Thoroughly wash plastic soda bottles or milk jugs with warm, soapy water.

2. Store sealed containers in a dark, dry, and cool place.

3. If after six months you have not used the stored water, empty it from the containers and repeat steps 1 through 3 above.

44.2124+0.81+7.335 significant digits
zhenek [66]

52  

Explanation:

We need to understand and apply the rules of significant figures when carrying out addition operations to solve this problem:

Rules of significant figures:

  • Non-zero digits are always significant in a given number
  • Any zeros between two significant digits are significant.
  • A final zero or trailing zeros in the decimal portion is significant.
  • Any leading zero in a decimal is significant.

In addition, the answer of the sum is given to the least number of significant digits of the given numbers:

 

        44.2124

    +    0.81

    +    7.335

sum  52.3574          

Now the least number of significant figure is 2 as seen in 0.81

we round the sum up to 52

Iron becomes rusted especially in damp air but never in a dry air,  this is one of the many unique characteristics of iron. Iron is also ductile and malleable. It is found in the seventh group of the periodic table. It has four different and unique crystalline forms and completely dissolves in dilute acids. The two chemical compounds that can be found or made from iron are the bivalent iron also known as ferrous and the trivalent iron or known as ferric compounds.

The state of matter with a specific volume but no definite shape is the _____ state.
bagirrra123 [75]

The state of matter with a specific volume but no definite shape is the <u>Liquid</u> state.

<u>Explanation:</u>

There are three states of matter according to chemical science: Solid, Liquid and Gas. There is not much space in among the molecules. The particles in a liquid are free to float, so while a liquid has a certain volume it has no definite form. Liquids are composed of atoms or molecules bound by inter molecular bonds.

Most of the liquids resist compression while some do not, unlike a gas, a liquid will not spread to fill any container room and will retain a fairly constant density. A characteristic liquid state property is surface tension that results to wetting phenomena. Water is perhaps the most frequent substance on Earth.
