Answer:

In one shot of expresso, there are:

4.12 x 10^-3 moles of C atoms

5.15 x 10^-3 moles of H atoms

2.06 x 10^-3 moles of N atoms

1.03 x 10^-3 moles of O atoms

The moles of carbon and hydrogen present in the caffeine in one shot of espresso are 4.11×  10⁻³moles and 5.14×  10⁻³moles respectively.

A mole is just a measuring scale. In reality, it is one of the International System for Units' seven foundation units (SI). When already-existing units are insufficient, new ones are created. The levels at which chemical reactions frequently occur exclude the use of grams, yet utilizing actual numbers of atoms, molecules, or ions would also be unclear.

6.02 x 1023 chemistry instructors make up a mole. Anytime we want to make a reference to a lot of different things, it is much simpler to type the word "mole" rather than the number "6.02x1023." In essence, it is the reason this specific unit was created.

caffeine in a shot of espresso = 1.00 × 10² mg/1000=0.1g

mole of caffeine =0.1g÷ 194.19g/mol

                           =5.149× 10⁻⁴mole

moles of carbon =8×5.149× 10⁻⁴

                           = 4.11×  10⁻³moles

moles of carbon = 10× 5.149× 10⁻⁴

                           =5.14×  10⁻³moles

Therefore, the moles of carbon and hydrogen present in the caffeine in one shot of espresso are 4.11×  10⁻³moles and 5.14×  10⁻³moles respectively.

Explanation:

Answer:

[tex]\boxed {\boxed {\sf 0.5043 \ mol \ P}}[/tex]

Explanation:

To convert from moles to grams, we must use the molar mass. This is found on the Periodic Table. Look for Phosphorous or P.

We can use this number as a ratio.

[tex]\frac{30.973762 \ g \ P }{1 \ mol \ P}[/tex]

Multiply by the given number of grams: 15.62

[tex]15.62 \ g \ P *\frac{30.973762 \ g \ P }{1 \ mol \ P}[/tex]

Flip the fraction so the grams of phosphorus cancel.

[tex]15.62 \ g \ P *\frac{1 \ mol \ P}{30.973762 \ g \ P }[/tex]

[tex]15.62 *\frac{1 \ mol \ P}{30.973762 }[/tex]

[tex]\frac{15.62 \ mol \ P}{30.973762 }[/tex]

Divide.

[tex]0.504297799 \ mol \ P[/tex]

The original measurement of grams has 4 significant figures, so our answer must have the same.

For the number we calculated, that is the ten thousandth place. The 9 in the hundredth thousandth place tells us to round the 2 to a 3.

[tex]0.5043 \ mol \ P[/tex]

There are 0.5043 moles of phosphorus in 15.62 grams.

Answer:

Explanation:

Answer:

The equation is not balanced.

Explanation:

The Law of Conservation of Matter is also called the law of conservation of mass or the Lomonosov-Lavoisier Law. This law postulates that "the mass is neither created nor destroyed, it only transforms." This means that the reactants interact with each other and form new products with different physical and chemical properties than the reactants because the atoms of the substances are arranged differently. But the amount of matter or mass before and after a transformation (chemical reaction) is always the same, that is, the amounts of the masses involved in a given reaction must be constant at all times, not changing in their proportions when the reaction ends. . In other words, then the mass before the chemical reaction equals the mass after the reaction. The exception to the rule is nuclear reactions, in which it is possible to convert mass into energy and vice versa.

This is, te law of conservation of matter states that since no atom can be created or destroyed in a chemical reaction, the number of atoms that are present in the reagents has to be equal to the number of atoms present in the products.

Then, you must balance the chemical equation. For that, you must first look at the subscripts next to each atom to find the number of atoms in the equation. If the same atom appears in more than one molecule, you must add its amounts.  

The coefficients located in front of each molecule indicate the amount of each molecule for the reaction. This coefficient can be modified to balance the equation, just as you should never alter the subscripts.

By multiplying the coefficient mentioned by the subscript, you get the amount of each element present in the reaction.

Then, taking into account all of the above, you can determine the amount of elements on each side of the equation:

Left side: 2 hydrogen H and 2 oxygen O  

Right side: 2 hydrogen H and 3 oxygen O

Since the quantity of each element is different on each side of the reaction, the equation is not balanced.

The balanced equation is:

2 H₂O₂ → 2 H₂O + O₂  

Answer:

7.08 cm

Explanation:

For number 1;

Rf = d1/d2

d1/12 cm

Rf = 1.0

d1 = 12 * 1

d1 = 12.0 cm

For number 2

Rf = d1/d2

Rf = 0.41

0.41= d1/12

d1 = 0.41 * 12

d1 = 4.92 cm

Separation distance= 12.0 - 4.92 = 7.08 cm

Answer:

In anaerobic respiration, glucose breaks down without oxygen. The chemical reaction transfers energy from glucose to the cell. Anaerobic respiration produces lactic acid, rather than carbon dioxide and water. Unfortunately this can lead to painful muscle cramps.

Explanation: Living things need energy for everything they do, including growing and reproducing. This energy comes from glucose. All animals and humans get glucose through eating it, but plants need to make their own glucose during photosynthesis.

Plants and animals transport glucose and oxygen to tiny structures in their cells, called mitochondria. Here, the glucose and oxygen take part in a chemical reaction. The reaction is called aerobic respiration, and it produces energy which transfers to the cells.

Aerobic respiration makes two waste products:carbon dioxide and water. Animals remove carbon dioxide from their bodies when they breathe out. In daytime, plants use some of this carbon dioxide for photosynthesis. At night, they release the carbon dioxide to their surroundings.

Answer:

D. gain one electron

Explanation:

In order to become a chemically stable ion, a neutral atom of sodium will gain one electron. Therefore, the correct option is option D.

Chemical stability in chemistry refers to a chemical system's thermodynamic stability. When a system reaches its lowest energy state or in thermodynamic equilibrium with its surroundings, thermodynamic stability occurs.

It could be a spontaneous process when the total number of atoms or molecules in a given shape is conserved despite the fact that individual particles or atoms change forms. In order to become a chemically stable ion, a neutral atom of sodium will gain one electron.

Therefore, the correct option is option D.

Explanation:

Answer:

116g/mol

Explanation:

Mg=24

NO2=46

multiple 46 by 2and then add 24

The molar mass of  Mg(NO₂)₂ is  116.33 g/mol.

To calculate the molar mass of Mg(NO2)2, we need to determine the atomic masses of each element in the compound and multiply them by their respective subscripts.

The atomic masses of the elements involved are:

Mg (magnesium) = 24.31 g/mol

N (nitrogen) = 14.01 g/mol

O (oxygen) = 16.00 g/mol

The compound Mg(NO₂)₂ contains one magnesium atom (Mg), two nitrate ions (NO₂), and each nitrate ion contains one nitrogen atom (N) and two oxygen atoms (O).

Molar mass of Mg(NO₂)₂ :

Mg: 1 × 24.31 g/mol = 24.31 g/mol

N: 2 × 14.01 g/mol = 28.02 g/mol

O: 4 × 16.00 g/mol = 64.00 g/mol

Now, add up the individual masses:

24.31 g/mol + 28.02 g/mol + 64.00 g/mol = 116.33 g/mol

Therefore, the molar mass of Mg(NO₂)₂  is 116.33 g/mol.
