Answer: 1.0324(g/ml)

We have the formula [tex]m = Vd[/tex]

Where m is the mass, V is the volume, and d is the density

Divide both sides by V, we get  [tex]d=\frac{m}{V}=\frac{19.1}{18.5} = 1.0324 (g/ml)[/tex]

Answer:  Technically, this cannot be answered, since none of the H atoms have a mass number assigned.  With the assumption noted delow, I calculate 1.012 as the average atomic mass.

Explanation:

My answer is based on assumed masses for the three H isotopes:

1H :   1 AMU

2H:   2 AMU   Deuterium

3H:    3AMU   Tritium

     AMU   Rel Abund.    Wt. Avg

1H 1     99.00%      0.99

2H 2       0.80%      0.016

3H 3       0.20%       0.006

Explanation:

Explanation:

For Mg, (1.2 g Mg/24 g Mg) = 0.05 mol Mg.

For Cl, (3.55 g Cl/35.5 g Cl) = 0.1 mol Cl

So the ratio now is

Mg:Cl = 0.05 : 0.1 = 1:2

I got the 1:2 ratio by dividing both by the smallest number, which is 0.05 mol. Therefore, the empirical for formula of the substance is [tex]MgCl_2[/tex]

The empirical formula of the compound formed when magnesium reacts with chlorine is MgCl₂.

To determine the empirical formula of the compound formed when magnesium (Mg) reacts with chlorine (Cl), we need to find the ratio of the elements in terms of moles.

First, we calculate the number of moles of each element:

Moles of Mg = Mass of Mg / Molar mass of Mg

Moles of Mg = 1.2 g / 24 g/mol

Moles of Mg = 0.05 mol

Moles of Cl = Mass of Cl / Molar mass of Cl

Moles of Cl = 3.55 g / 35.5 g/mol

Moles of Cl = 0.1 mol

Next, we determine the simplest whole-number ratio between the moles of Mg and Cl:

Mg:Cl = 0.05 mol : 0.1 mol

To simplify the ratio, we divide both values by the smaller value (0.05 mol in this case):

Mg:Cl = 0.05 mol / 0.05 mol : 0.1 mol / 0.05 mol

Mg:Cl = 1 : 2

Therefore, the empirical formula of the compound formed when magnesium reacts with chlorine is MgCl₂.

Answer:

(1) It does not suffer from spectral interference, which occurs in flame emission spectroscopy.

(2) By atomic absorption technique, traces of one element can easily be determined in presence of high concentration of other elements.

The technique makes use of the atomic absorption spectrum of a sample in order to assess the concentration of specific analytes within it. It requires standards with known analyte content to establish the relation between the measured absorbance and the analyte concentration and relies therefore on the Beer–Lambert law.

In SO2 and SO3, oxygen combines with sulphur in a fixed ratio.

The law of multiple proportion states that if two elements combine with each other to form more than one chemical compound, then the various masses of the elements which combine with a fixed mass of the other element are in simple multiple ratios.

To illustrate this law, sulphur forms two oxides, SO2 and SO3. The ratio of the oxygen that combines with a fixed mass of sulphur  in the two compounds is 2:3 in accordance to the law of multiple proportion.

The mass of CO₂ in grams without exponential notation and with the appropriate metric prefix is 31.6 Eg.  

First, let's calculate the amount of mass in grams of 31.6 billion metric tons.

Knowing that 1 metric ton is equal to 1000 kg, 31.6 billion metric tons is:

[tex]m = \frac{1000 kg}{1 \: metric \: ton}*\frac{1000 g}{1 kg}*31.6 \cdot 10^{12} \: metric \: ton = 3.16 \cdot 10^{19} g[/tex]              

The metric prefix that is close to the above result is exa (E), which is equal to 10¹⁸.

Therefore, the mass of CO₂ in grams without exponential notation and with the appropriate metric prefix is 31.6 Eg (exa-gram).

Hi Lovelys!!

Explanation:

There are two answer my me: Matter and Volume

Matter is anything that has mass and takes up space. Mass gives an object the property of weight and inertia (resistance to change in the motion of an object).

Volume simply refers to the space an object takes up. Depending on the physical state of an object, there are a couple ways to measure volume. If we are trying to measure the volume of a box, for instance, we would multiply the length of the box by its height and by its width.

Explanation:

Salt lowers the freezing point of water by interfering with the intermolecular forces of the water molecules, allowing for less interactions between water molecules.

The Freezing point is the temperature of a liquid at which it changes its state from liquid to solid at atmospheric pressure.

Salt molecules block water molecules from packing together when temperature is lowered. It then prevents them from becoming ice. More water molecules leave the solid phase than the ones entering the solid phase. Freezing point depression occurs when the freezing point of the liquid is lowered by addition of solute.

Hence, option B is correct.
