Which element, represented by X, reacts with fluorine to produce the compound XF2?(1) aluminum (3) magnesium
(2) argon (4) sodium

Answers

Answer 1
Answer: The answer is (3) magnesium. Aluminum usually has valence of +3 and Sodium usually has valence of +1. Argon is usually not react with others. Because it is already stable with 8 electrons at the outer shell.

Please help !!

Answers

Answer: as the larger quantity

Explanation:

Binary Solution is a homogeneous mixture of two components called as solute and solvent.

Solute is the component which is present in smaller proportion and is solid for solid in liquid solution.

Solvent is the component which is present in larger proportion and is liquid for solid in liquid solution.

Thus solvent is  is usually referred to as the component of a solution which is present as the larger quantity.
As the larger quantity.

Outliers existing in a data set will have the greatest impact on __________. A. the mean B. the median C. the mode D. the middle

Answers

Outliers are the ones that are least precise among the data. They may be due to experimental or human errors. In the case of having outlier in the data, its effect is most significant n computing the mean because they are included in the calculation. The median mode and middle do not involve calculation but only the ordination, so they are not affected.

Answer:

Outliers existing in a data set will have the greatest impact on :

            option: A is the correct answer.

               A.  The mean.

Step- by- step explanation:

We know that an outlier is a data value or the data point that stands out of the rest of the data points of the set i.e. it either attains a too high or too low value as compared to other data points.

            Hence, the outlier will effect the mean of the data set.

( Since, when a too low value is present in the set then after removing that value the mean of remaining elements or data points will increase after removing the outlier.

For example if we have data set as:

       1      30   34    39    41    45

Then mean of the set is:

Mean=(1+30+34+39+41+45)/(6)\n\n\nMean=31.667

and on removing 1 from the set we get:

Mean=(30+34+39+41+45)/(5)\n\n\nMean=37.8

Hence, we see that the mean is increased.

Similarly, if there is a data value which is too high then after removing that element the mean of the remaining data points will decrease )

Why is water (H2O) considered the "universal solvent"?

Answers

It is considered as a universal solvent since most substances dissolve in water. And comparing it to other liquids, it is the one who dissolves a wide range of substances. Also, it is an important substance for every living thing.

Converting carbon to nitrogen by increasing the number of protons from 6 to 7 and decreasing the number of neutrons from 8 to 7 is an example of what type of decay?

Answers

Answer: The given decay process is beta decay.

Explanation:

Beta-decay is defined as the decay process in which a neutron gets converted into a proton and an electron releasing a beta-particle. The beta particle released carries a charge of -1 units and has a mass of 0 units.

_Z^A\textrm{X}\rightarrow _(Z+1)^A\textrm{Y}+_(-1)^0\beta

The chemical reaction for converting carbon nucleus to nitrogen nucleus, the equation follows:

_6^(14)\textrm{C}\rightarrow _7^(14)\textrm{N}+_(-1)^0\beta

Thus, the given decay process is beta decay.

this is beta decay as the mass number stays the same but proton number changes, this is specifically beta minus as a neuron changes into a proton
