Write the charges for each part of this equation. ​

State the given:

Moles of Sulfur = 5 moles

Molar mass of Sulfur = 32.06g/mol

Look through the formulas:

Moles = Mass/Molar Mass

Rearrange the equation:

Mass = Moles x Molar mass

Plug in your given:

5 moles Sulfur   x   32.06g

                                 1 mol

= 160.3g of Sulfur

Answer:

The enthalpy of combustion of 1 mole of benzene is 3169 kJ/mol .

The first step in answering this question is to obtain the balanced thermochemical equation of the reaction. The thermochemical equation shows the amount of heat lost or gained.

The thermochemical equation for the combustion of benzene is;

2 C6H6(l) + 15 O2(g) → 12 CO2(g) + 6 H2O(g) ΔrH° = -3169 kJ/mol

We can see that 1 mole of benzene releases about 3169 kJ/mol of heat.

In giant covalent structures such as graphite or diamond, the atoms form strong bonds by sharing electrons. Therefore, the given statement is true.

A covalent bond can be defined as a chemical connection formed by the sharing of electron sets between particles. A covalent bond can be created by the mutual sharing of electrons from both atoms.

The pair of electrons that are shared in this kind of bonding is known as the shared or bonding pair. Covalent bonds are the sharing of bonding pairs of electrons that will provide the stability of the atom in its outer shell.

Elements that have very high ionization energies are incapable of exchanging electrons or elements having low electron affinity cannot accept electrons. Covalent bonding between two non-metallic atoms is characterized by the equal sharing of electrons between the atoms and covalent bonds with an electronegativity difference of participating atoms is more than 2.0.

Therefore, a giant structure like a diamond has strong covalent bonds that require a lot of energy to break.

Answer:

they have same atomic number as they are the same element & electrons

Answer: they both have the atomic (proton number) as they are the same element hence they also they have the same number of electrons. Therefore they have similar chemical properties, as the electrons determine the chemical property of an element.

Explanation: The numbers 35 and 37 are the mass numbers for the two isotopes of chlorine. They both have the same atomic number (proton number ) as they are the same

1. mol = 77.56/100 = 0.7756 mol

2. mol = 2.55 × 10^24/6.02 × 10^23 = 4.236 mol mass = 4.236 × 74.5 = 315.582 g

3. mass = 0.0931 × 208.3 = 19.393 g

4. mol = 1.55 × 10^22/6.02 × 10^23 = 0.0257 mol

5. molecules = 0.664 × 6.02 × 10^23 = 3.997 × 10^23 molecules

6. mol = 86/242 = 0.355 mol

7. mol = 7.88 × 10^23/6.02 × 10^23 = 1.309 mol mass = 1.309 × 44 = 57.596 g

8. mass = 7.56 × 62 = 468.72 g

9. mol = 7.56/84 = 0.09 mol

10. mol = 8.55 × 10^21/6.02 × 10^23 = 0.014 mol mass = 0.014 × 58.5 = 0.819 g

Temperature measures the average kinetic energy of particles of the substances. Therefore, the correct option is option A.  Temperature is a physical quantity.

Temperature is used to measure degree or intensity of heat of a particular substance. Temperature is measured by an instrument called thermometer.

Temperature can be measured in degree Celsius °c, Kelvin k or in Fahrenheit. Heat always flow from higher temperature source to lower temperature source.

We can convert these units of temperature into one another. The relationship between degree Celsius and Fahrenheit can be expressed as:

°C={5(°F-32)}÷9

The boiling points of five liquids have been measured 10 times each by a team of scientists, with fairly consistent results. the next step would be to  Test a sixth liquid to see if it follows patterns in the rest of the data.

Therefore, the correct option is option A.
