Answer:

54.0902 g

Explanation:

Mass of Carbon(C)= 12.0107

Mass of Hydrogen(H)= 1.0079

(12.0107)(4) + (1.0079)(6) = 54.0902

Explain why the standard enthalpy of formation () for Cl2 (g) is zero, but its standard entropy is larger than zero.

Galina-37 [17]

The standard enthalpy of formation for chlorine is zero but the standard entropy is larger than 0 because it is the elemental state of chlorine.

The standard enthalpy of formation for chlorine is zero because cl2 is the elemental state of chlorine and it does not require any energy for the formation of the standard state of chlorine.

The entropy of any system cannot be negative. It can only be positive or zero.

The entropy of a system will become zero only at a absolute zero temperature.

That's why the entropy of chlorine in elemental state is more than zero because absolutely zero temperature can't be obtained.

Maggie is solving a chemistry riddle her clue is to take the number of valence electrons in halogens and subtract it by the numb

Novay_Z [31]

The answer to the riddle Maggie is solving is 6

To determine the answer to the riddle Maggie is solving,

We will subtract the number of valence electrons in halogens by the number of valence electrons in alkali metals.

First, let us define what is meant by valence electrons

Valence electrons are those electrons that reside in the outermost shell surrounding an atomic nucleus.

Now, we will the determine the respective number of valence electrons in halogens as well as the number of valence electrons in alkali metals.

For Halogens

Halogens are the group 17 (group 7A) elements in the periodic table. Examples are Fluorine, Chlorine, Bromine etc.

Halogens have 7 electrons in their outermost shell

For Alkali metals

Alkali metals are the group 1 metals. Examples are Lithium, Sodium, Potassium etc.

Alkali metals have 1 electron in their outermost shell

Now, for the answer to the riddle,

Answer to the riddle = Number of valence electrons in halogens - Number of valence electrons in Alkali metals

Answer to the riddle = 7 - 1

∴ Answer to the riddle = 6

Hence, the answer to the riddle Maggie is solving is 6

True or false when heat is added to atoms the molecules vibrate much more slowly

Temka [501]

Answer:

false

Explanation:

The particles are held together too strongly to allow movement from place to place but the particles do vibrate about their position in the structure. With an increase in temperature, the particles gain kinetic energy and vibrate faster and more strongly

When does a substance have a definite shape?

choli [55]

A substance has a definite shape when it is a solid, that way it can hold its shape.
