Elements are composed ofA) many type of atoms.

B) the same type of atom.

C) many different compounds.

D) the same type of compound.

Answers

Answer 1

Answer: The correct answer is B, 'the same type of atom'. By definition, an element is a single type of atom. They are the most basic forms of matter, and so they cannot be more than one kind of atom, and they also cannot be a compound, since compounds are made up of multiple atoms.

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 )

What is the Charles and boyles law?

Answers

The Charles and Boyles law,is a gas law that says that the pressure and volume of a gas have an inverse relationship, when temperature is held constant. If you increase the pressure 10 times, the volume will decrease 10 times. You have a fixed mass of gas, so n (the number of moles) is constant. R is always constant - it is called the gas constant. Boyle's Law demands that temperature is constant as well.

What Kelvin temperature is equal to -33DC? A) 306K B) -33K C) 240K D) 33K

Answers

Final Answer:

$\boxed{\boxed{\huge\textsf{$\rm -33^(\,\circ)C=240.15\,K$}}}$

Kelvin Absolute Temperature:

The kelvin, symbol K, is a unit of measurement for temperature. The Kelvin scale is an absolute scale, which is defined such that 0 K is absolute zero, the lowest temperature possible on Earth.

Historically developed from the Celsius scale, the conversion is thus:

$\boxed{\Large\textsf{$\rm 0^(\,\circ)C=273.15\,K$}}$

And absolute zero, 0 K = -273.15° C, the lowest temperature possible.

Knowing this, we can solve the question as:

$\Large\textsf{$\rm -33^(\,\circ)C=(-33+273.15)\,K$}\n\n\boxed{\boxed{\Large\textsf{$\therefore\rm -33^(\,\circ)C=240.15\,K$}}}$

1 ℃ = 273.15 K.

The Kelvin temperature equal to -33℃ is 240 K.

Which type of change must occur to form a compound?(1) chemical (3) nuclear(2) physical (4) phase

Answers

To form a compound, we need to change the structure of the molecules and mostly form new bonds between molecules to result in a compound.

A nuclear change changes the element completely and forms new elements, so nuclear is a wrong choice.
A phase change only changes the phase of the element (solid, liquid or gas) but does not change structure, so phase is a wrong choice
A physical change does not change the structure of the molecules, so physical is also a wrong choice.

On the other hand, a chemical change changes the structure of molecules and/or breaks/forms bonds.
Therefore, the right choice is chemical.

Answer:

1) Chemical

What is the relationship
between different forms of energy?

Answers

Answer:

Energy exists in different forms, all of which can be classified as either potential energy or kinetic energy. Potential energy is energy stored in an object due to its position or arrangement. Kinetic energy is energy of an object due to its movement - its motion.
