Chemists use the periodic table to organize the elements. What are some ways in

Physics

Alisiya [41]3 years ago
3 0

Answer:

A. It groups elements that have similar properties.

C. It allows scientists to predict how a particular element will interact with others,

Explanation:

The periodic table of elements is a very useful table in chemistry which allows for the grouping of elements based on their atomic number.

Atomic number of elements is the number of protons they contain. The periodic table is based on the periodic law.

On the periodic table, there are trends and patterns from groups to groups and periods to periods.

  • It has been shown that elements in the same group have similar chemical properties. This is due to the number of valence electrons they have.
  • Also, based on the chemical and physical properties of a group, we can predict if the elements in one group will react with elements in another group

Y=mx+b if y=8.18 m=1.31 b=17.2 then find x
Dafna1 [17]

Plug in the corresponding values into y = mx + b

8.18 in for y

1.31 in for m

17.2 in for b

8.18 = 1.31x + 17.2

Now bring 17.2 to the left side by subtracting 17.2 to both sides (what you do on one side you must do to the other). Since 17.2 is being added on the right side, subtraction (the opposite of addition) will cancel it out (make it zero) from the right side and bring it over to the left side.

8.18 - 17.2 = 1.31x

-9.02 = 1.31x

Then divide 1.31 to both sides to isolate x. Since 1.31 is being multiplied by x, division (the opposite of multiplication) will cancel 1.31 out (in this case it will make 1.31 one) from the right side and bring it over to the left side.

-9.02/1.31 = 1.31x/1.31

x ≈ -6.8855

x is roughly -6.89

Hope this helped!

Why is figure 5 an unhelpful visualization tool for this data set? <br><br> Please help!
Paraphin [41]

Explanation:

Because the temperature and the radiation are not correlated, they're not represented as functions of each other, they're represented as independent variables thus using graph 5 you cannot figure out how one affect another

Why is the curve between 1950 and 1980 relatively flat and centered around zero degrees difference from the baseline? (Hint: how
zimovet [89]

Look at the title of the graph, in small print under it.

Each point is "compared to 1950-1980 baseline". So the set of data for those years is being compared to itself. No wonder it matches up pretty close !

How does state-dependence impact memory recall?
NNADVOKAT [17]

Answer:

The state of the person under the influence of alcohol

The place in which the memory was initially encoded for the retrieval of information.

Retrieval of information is generally better given similar rather than different contextual cues Motivational and emotional factors

These are also likely to affect recall and forgetting.
