A chemist carefully measures the amount of heat needed to raise the temperature of a 278.0g sample of C5H12S from 0.8degree cels

ius to 15.9 degree celsius . The experiment shows that 8.46X10^3J of heat are needed. What can the chemist report for the molar heat capacity of C5H12S ? Be sure your answer has the correct number of significant digits.

Answer:

The answer to your question is    C = 2.01 J/g°C

Explanation:

Data

mass = m = 278 g

Temperature 1 = T1 = 0.8°C

Temperature 2 = T2 = 15.9 °C

Heat = Q = 8.46 x 10³ J

Heat capacity = C = ?

Process

1.- Write the formula to calculate the heat

        Q = mC(T2 - T1)

2.- Solve for C

        C = Q / m(T2 - T1)

3.- Substitution

         C = 8.46 x 10³ / 278 (15.9 - 0.8)

4.- Simplification

          C = 8.46 x 10³ / 4197.8

5.- Result

          C = 2.01 J/g°C

Which phrase best defines a chemical bond?
Mice21 [21]

Answer:

Chemical bond can be define as a force holding atoms firmly together to a form molecules.

Explanation:

Chemical bond is a strong attraction between atoms, molecules or ions that enhance the formation of chemical compounds. The bonds may be due from the electrostatic force of attraction between opposite charged ions or through the sharing of electrons.

Types of chemical bond

There are four types of chemical bonds

- covalent bond

- polar bond

- ionic bond

- hydrogen bond

Ionic bond involves the transfer of an electron which involves one atom receiving and the other giving out

Covalent bond involves the sharing of electrons between two atoms

Polar bonds involves two atoms connected by covalent bonds which may exert different attractions for the electrons in the bond resulting into unevenly charges distribution

Hydrogen bond: this is found mostly in water H2O. They are polarized

Which fossil fuel has the least amount of carbon dioxide released in the air each year
Natali5045456 [20]

The correct answer is - natural gas.

The natural gas is the fossil fuel that releases the least amount of carbon dioxide in the atmosphere. It actually releases very little to none. The reason for that is that the natural gas is a fossil fuel which has the methane as its main ingredient. Even when used, it is not causing some serious pollution, instead the pollution comes from not well managed infrastructure and movement from one place to another of the natural gas. The biggest problem, pollution wise, comes from the leaking of the natural gas, when methane is released into the atmosphere.
