<u>Answer:</u> The given number is equal to $-9.0606\times 10^{5}$

<u>Explanation:</u>

Scientific notation is defined as the notation in which a number is expressed in the decimal form. This means that the number is always written in the power of 10 form. The numerical digit lies between 0.1.... to 9.9.....

If the decimal is shifting to right side, the power of 10 is negative and if the decimal is shifting to left side, the power of 10 is positive.

We are given:

A quantity having a value of -906,060

Converting this into scientific notation, we get:

$\Rightarrow -906,060=-9.0606\times 10^{5}$

As, the decimal point is shifting to left side, thus the power of 10 is positive.

Hence, the given number is equal to $-9.0606\times 10^{5}$

As a science major, you are assigned to the "Atomic Dorm" at college. The first floor has one suite with one bedroom that has a

lidiya [134]

Explanation:

The first student will be on the lower bunk on the first floor because 1. They want on the lowest available floor and 2. They want to be in a lower bunk if available.

7 students are in the TOP bunks because 1. They want on the lowest available floor and 2. They want to be in a lower bunk if available. Therefore, all the rooms up till the third floor (Remember, third floor has 3 suites), so the first floor is filled - 1 person on the top bunk, 2 floor is filled- 4 persons and the third floor; the first suite is filled - 1 person and the second suite is a little partially filled- 1 person.

Following the criteria 1, 2 and 3, the 21st student occupies the third suite on the third floor because all the floors (1 and 2) are occupied so the third suite on the third floor is still vacant.

From the criteria there are therefore 10 persons at the TOP bunk. All the rooms up till the third floor are filled, so the first floor is filled - 1 person on the top bunk, second floor is filled (2 suites) - 4 persons and the third floor; the first suite and second suite is filled - 4 persons; the thirs suite has 6 persons present so 1 person is at the top bunk.

The temperature at the point of intercept of the plotted data with the Temperature axis is:

Mice21 [21]

Answer: The temperature at the point of intercept is -273°C.

Explanation: Intercept is a point on a graph which crosses the x and y axes.

Here, The X-axis represents Temperature in °C and Y-axis represents the Volume in mL.

On X-axis, the major division is 100 and minor division is 10. The slope intercepts the X-axis at third minor division from the origin. Hence, the temperature of intercept corresponds to -273°C.

Write the empirical formulas of the following compounds: (a) Al2Br6, (b) Na2S2O4, (c) N2O5, (d) K2Cr2O7, (e)H2C2O4.

babunello [35]

Answer:1. $AlBr_3$

2. $NaSO_2$

3. $N_2O_5$

4. $K_2Cr_2O_7$

5. $HCO_2$

Explanation:

Molecular formula is the chemical formula which depicts the actual number of atoms of each element present in the compound.

Empirical formula is the simplest chemical formula which depicts the whole number of atoms of each element present in the compound.

1. $Al_2Br_6$ has empirical formula of $AlBr_3$

2. $Na_2S_2O_4$ has empirical formula of $NaSO_2$

3. $N_2O_5$ has empirical formula of $N_2O_5$

4. $K_2Cr_2O_7$ has empirical formula of $K_2Cr_2O_7$

5. $H_2C_2O_4$ has empirical formula of $HCO_2$

The chemical formula H2O represents one molecule of water.

Gennadij [26K]

There is a total of three atoms present in the water (H₂O) molecule.

An atom is the smallest particle of an element that may or may not be capable of independent existence.

<h3>What is a molecule?</h3>

A molecule is the smallest particle of an element or compound that can exist freely.

<h3>What is a subscript?</h3>

Subscripts are the numbers that come below after a symbol. They tell you the number of atoms of an element. If there is no subscript then it is understood that the subscript is 1.

<h3>How to calculate the number of atoms in a molecule?</h3>

For calculating the number of atoms in a molecule, add the subscripts of that molecule, and you will get the total atoms of it.

For example, in molecule C₂H₅O, there are 2 carbon atoms, 5 hydrogen atoms, and 1 oxygen atom.

Add the subscripts

2 + 5 + 1 = 8

Hence, there is a total of 8 atoms in C₂H₅O.

For the H₂O molecule,

2 + 1 = 3

Hence, there is a total of 3 atoms present in one water molecule.
