Explanation:

The volume of the dry nitrogen gas at STP is 57.4 mL

From the question given above, the following data were obtained:

Initial volume (V₁) = 77 mL

Initial temperature (T₁) = 50 °C = 50 + 273 = 323 K

Initial pressure (P₁) = 763 – 92.5 = 670.5 mmHg

Final temperature (T₂) = STP = 273 K

Final pressure (P₂) = 760 mmHg

The volume of the dry nitrogen can be obtained by using the combine gas equation as follow:

[tex] \frac{P_1V_1}{T_1} = \frac{P_2V_2}{T_2} \\ \\ \frac{670.5 \times 77}{323} = \frac{760 \times V_2}{273} \\ \\ cross \: multiply \\ \\ 323 \times 760 \times V_2 = 670.5 \times 77 \times 273 \\ \\ divide \: both \: side \: by \: 323 \times 760 \\ \\ V_2 = \: \frac{670.5 \times 77 \times 273 }{323 \times 760} \\ \\ V_2 = 57.4 \: ml[/tex]

Therefore, the volume of the dry nitrogen gas is 57.4 mL

Answer:

5.57 x 10^24 atoms

Explanation:

first, you are seeking the number of ATOMS of Boron.

Boron has an Atomic mass of 10.8 g/mol (see #5 on the periodic table)

100 gm of Boron would have 100 g /10.8 g/mol =9.26 moles

each mole has Avogadros number of atoms 6.02 x 10^23

9.26 moles has 9.26 x 6.02 x 10^23 atoms =5.57 x 10^24 atoms

Conversion of energy

Explanation:

Shaking the sand is a form of kinetic energy. The friction of the sand particles rubbing against each other converts the kinetic energy to heat energy. Some of the kinetic energy also converts into the energy of sound waves, which you can hear while you shake the sand.

Answer:

the charge or oxidation number on the cation and anion.

Explanation:

The factor that governs the formula of an ionic compound such as Ca3N2 is the charge or oxidation number on the cation and anion.

In the example, Ca has a +2 charge, N has a -3 charge

So we need 3 x ( +2) to balance 2 x (-3) and have an electrically neutral compound, so

+6 -6 =0

The factor that governs the formula of an ionic compound such as Ca₃N₂ is charge.

Those compounds in which ionic bond is present between the cation and anion is known as ionic compound.

The most important factor that is essential for the formation of ionic compounds are charge i.e. positive charge and negative charge. In the given compound Ca₃N₂, Calcium (Ca) is present in the +2 oxidation state and Nitrogen is present in the -3 oxidation state. So due to attraction between these charges they make a ionic compound.

Hence charge is important factor.

Answer: 7

Explanation:

Answer:

1.) Tin oxide + Carbon → Tin + Carbon monoxide.

2.) Lead oxide + Carbon → Lead + Carbon monoxide.

These equations show that the metals are being extracted by their oxides by heating with carbon. This is because the metals (Tin and Lead) are less reactive than carbon. Remember, extraction methods of metals are determined by their reactivity. Since the elements tin and lead are less reactive than carbon, the extraction process of heating with carbon is needed.  Remember that when a metal heats with carbon, the carbon displaces the metal from the compound and removes the oxygen from the oxide. Leaving you with the metal and carbon monoxide.

Answer:

An ion is a charged atom or molecule. It is charged because the number of electrons do not equal the number of protons in the atom or molecule. An atom can acquire a positive charge or a negative charge depending on whether the number of electrons in an atom is greater or less then the number of protons in the atom.

The pressure of this gas in atm is equal to 1.63 atm.

Given the following data:

To calculate the pressure of this gas, we would use the ideal gas law equation;

Where;

Substituting the given parameters into the formula, we have;

[tex]P=\frac{0.742 \times 0.0821 \times 291}{10.91} \\\\P = \frac{17.73}{10.91}[/tex]

Pressure, P = 1.63 atm.

Answer:

c. pairs of electrons are shared between two nonmetal atoms

Explanation:

Bonding between elements solely depends on their electronegativity. When there is large difference in electronegativity, those atoms form ionic bonds. Covalent bonds form when the difference is minimal, or none at all. When the difference between electronegativities is 0 or very close to 0, then they form pure covalent bonds, or nonpolar bonds. An example of this are diatomic molecules. Diatomic molecules are two of the same atom that form nonpolar covalent bonds because their electronegativy difference is 0, as they have the same electronegativity. When the electronnegativties have bit of difference, they form polar covalent bonds.

When 1-bromo-2-methylpropane is reacted with methoxide the same product 1-methylprop-2-ene is obtained. This reaction is attached in image below:

The SN2 reaction is a nucleophilic substitution reaction that breaks one bond while forming another. The rate-determining step of the reaction involves two reacting species. SN2 is an abbreviation for Substitution Nucleophilic Bimolecular.

The reaction is bimolecular because two molecules are present in the transition state, as indicated by the number 2 in the SN2 symbol. As a result, the rate of the reaction is affected by the concentrations of both the nucleophile and the substrate.

The SN2 reaction is a nucleophilic substitution with two components in the rate determining step. -SN2 reactions are bimolecular, with bond-forming and bond-breaking steps occurring simultaneously. There is no intermediate in -SN2 reactions.

Thus, product 1-methylprop-2-ene is obtained.
