It differs because it shows different volume of information and it gives a different point of indicanton of numbers.

Answer:

A graph with anolamalous data has some points that are outside the range of tolerance, which is given by the deviation. However, this graph will have a clear trend and only some points will be outside the expected range.

On the other hand, a graph with no trend will not have a range where you expect to find results, but the points will be in different parts.

A certain compound of bromine and fluorine is used to make UF6, which is an important chemical in the processing and reprocessin

Aleksandr [31]

Answer: The empirical formula is $BrF_3$

Explanation:

If percentage are given then we are taking total mass is 100 grams.

So, the mass of each element is equal to the percentage given.

Mass of Br= 58.37 g

Mass of F = (100-58.37) = 41.63 g

Step 1 : convert given masses into moles.

Moles of Br= $\frac{\text{ given mass of Br}}{\text{ molar mass of Br}}= \frac{58.37g}{80g/mole}=0.73moles$

Moles of F = $\frac{\text{ given mass of H}}{\text{ molar mass of H}}= \frac{41.63g}{19g/mole}=2.2moles$

Step 2 : For the mole ratio, divide each value of moles by the smallest number of moles calculated.

For Br = $\frac{0.73}{0.73}=1$

For F = $\frac{2.2}{0.7}=3$

The ratio of Br: F= 1 : 3

Hence the empirical formula is $BrF_3$

What is the element that has the ending configuration of 4d^4

Maru [420]

Answer:

Molybdenum

Explanation:

Molybdenum is a chemical element with the symbol Mo and an atomic number of 42. This implies a total of 42 electrons in its orbital.

The atomic weight of Mo is 95.94g/mol.

Using the sublevel notation system, the electrons can be filled into the orbitals as shown below:

1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p⁶ 5s² 4d⁴

The ending configuration of this element is therefore 4d⁴

Brrunno [24]

The answer is; C

Due to the intense heat and pressure on the rocks, they undergo physical and chemical changes and become new types of rocks called metamorphic rocks. An example of this change is that small crystals may be squeezed into large crystals and the crystals may be rearranged.

A piece of chalk can be broken into small particles by hammering but a piece of iron cannot be broken into small particles by ha

shtirl [24]

Answer:

The strength of these force of attraction is lesser in chalk hence it could be easily broken into small pieces by hammering. But the strength of inter molecular force of attraction is very strong in iron therefore it is not possible to break them into pieces by hammering.

Explanation:

hope this helps :)
