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

              Sum   1.012

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.

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).

Answer:

When the concentrations of the reactants are raised, the reaction proceeds more quickly. ... When solids and liquids react, increasing the surface area of the solid will increase the reaction rate. A decrease in particle size causes an increase in the .

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.

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.
