What is the new volume when the pressure of 20 milliliters of an ideal gas decreases from 202 kPA to 101 kPA?

Which of the following is not equal to 485 L?

ELEN [110]

Answer:

$4.85 * 10^4\ mL$

Explanation:

Given

485 L

Required

Determine the measurement not equal to 485L

$0.485\ kL$

From standard unit of conversion;

1 KL = 1000 L

Multiply both sides by 485

$485 * 1 KL = 485 * 1000 L$

$485KL = 485000L$

Divide both sides by 1000

$\frac{485KL}{1000} = \frac{485000L}{1000}$

$0.485KL = 485L$ ---- This is equivalent

---------------------------------------------------------------------------------------------

$4.85 * 10^4\ mL$

From standard unit of conversion;

1000 mL = 1 L

Multiply both sides by 485

$485 * 1000 mL = 1 L * 485$

$485000\ mL = 485\ L$

Convert to standard form

$4.85 * 10^5\ mL = 485\ L$

Hence; $4.85 * 10^4\ mL$ is not equivalent to 485L

---------------------------------------------------------------------------------------------

$48500 \ cL$

From standard unit of conversion;

100 cL = 1 L

Multiply both sides by 485

$485 * 100 cL = 1 L * 485$

$48500\ cL = 485\ L$

Convert to standard form

$4.85 * 10^4\ cL = 485\ L$ ---- This is equivalent

---------------------------------------------------------------------------------------------

$4.85 * 10^8 \$ μL

From standard unit of conversion;

1000000 μL = 1 L

Multiply both sides by 485

$485 * 1000000uL = 1 L * 485$

$485000000uL = 485\ L$

Convert to standard form

$4.85 * 10^8\ uL = 485\ L$ ---- This is equivalent

From the list of given options;

$4.85 * 10^4\ mL$ is not equivalent to 485L

The empirical formula is:

Hunter-Best [27]

Answer:

C. the relative number of atoms of each element, using the lowest whole ratio.

Explanation:

The empirical formula is how we simplify the whole formula to simplify it to its smallest indivisible parts.

It is definitely not the actual number of atoms. If you see an empirical formula, don't think that it's the full thing.

It is also not a representation of a compound to show its atoms' arrangement: this would be a Lewis dot structure, or a ball and stick model, or something similar. We don't use the empirical formula for this purpose.

Which of the following has a polar covalent bond? b. Which of the following has a bond closest to the ionic end of the bond spec

Marizza181 [45]

Explanation:

Polar covalent bonding is the type of the chemical bond in which the pair of the electrons is unequally shared between the two atoms. As a result, the atom with higher value of electronegativity acquires a slightly negative charge and the atom with lower value of electronegativity acquires a slightly positive charge.

In the molecule of $CH_3NH_2$ , the bond which is closest to ionic end of bond spectrum is N-H bond because the nitrogen atom is more electronegative than hydrogen and is ionic in nature.

In the molecule of $CH_3CH_3$ , the bond which is closest to ionic end of bond spectrum is no one because there is not much difference between carbon and hydrogen for the bond to be said as ionic.

In the molecule of $CH_3OH$ , the bond which is closest to ionic end of bond spectrum is O-H bond because the oxygen atom is more electronegative than hydrogen and is ionic in nature.
