1 mol of Silicon = 28.0855 g (in average)

then

1 mol = 6.022*10^23 atoms

then

28.0855/(6.022*10^23) g/atom

4.66381*10^-23 g per atom

A pair of students determining the molarity of their unknown HCl solution calculates the concentration to be 0.0961 M on their f
Varvara68 [4.7K]

Answer:

Yes.

Explanation:

It should be noted that the meaning of molarity is the ratio of moles of solute per liter of solution.

It should be understood that when determining or finding the molarity of an unknown compound ,the process should be performed or carried out at least 3 times. This is done to remove any form of doubt.

The first calculated value for the concentration of the compound will be regarded as rough value, while the second and the third will be regarded as the first and second values respectively.

In this case, the third value for the concentration of HCl will be calculated to for confirmation of other value, that is to be finally sure of its concentration.

CH4 (g) yields C(g) + 4H (g) (reaction for expansion)
anyanavicka [17]

Answer:

Here's what I find.

Explanation:

\rm CH$_{4}$(g) $\, \rightleftharpoons \,$ C(g) + 4H(g)

\text{Same} =\begin{cases}1. & \text{The number of atoms of each element}\\2. & \text{The state of the methane molecules}\\4. &\text{The state of the carbon atoms}\\\end{cases}

\text{Different} =\begin{cases}3. & \text{The enthalpy change of the reaction}\\\end{cases}

The sign of ΔH changes when you reverse the reaction.
