We are provided the volume at STP of H2S to be provided for the reactivity. This would certainly be the beginning allude for the calculations. We perform as follows:

45.0 L H2S ( 1 mol / 22.4 L) ( 3 mol O2 / 2 mol H2S ) ( 22.4 L / 1 mol ) = 67.5 L O2 needed

A , 210.3 g

Explanation:

Given data:

Number of moles of SiO₂ = 3.50 mol

Mass of SiO₂ = ?

Solution:

Formula:

Number of moles = mass/molar mass

Molar mass of SiO₂ = 60.08 g/mol

by putting values,

3.50 mol = mass/60.08 g/mol

Mass = 3.50 mol × 60.08 g/mol

Mass = 210.3 g



the worth of kc for the following reaction is 0.630 at 409 K N2O4(g) --> 2NO2(g) if a reactivity vessel at that temperature int

carolannpeacock.com: The concentration of nitrogen dioxide at equilibrium is 0.063 M

Explanation:

We are given:

Initial concentration of nitrogen dioxide = 0.0250 M

Initial concentration of dinitrogen tetraoxide = 0.0250 M

For the offered chemical equation:

*

Initial: 0.025 0.025

At eqllm: 0.025-x 0.025+2x

The expression of

*
for above equation follows:

*
^2}" alt="K_c=frac^2" align="absmiddle" class="latex-formula">

We are given:

*

Putting values in over expression, we get:

*

Neglecting the negative value of "x", because concentration cannot be negative

So, equilibrium concentration of nitrogen dioxide = (0.025 + 2x) = <0.025 + 2(0.019)> = 0.063 M

Hence, the concentration of nitrogen dioxide at equilibrium is 0.063 M

Which equation is NOT balanced? a. 2H2 + O2 → 2H2O c. Fe2O3 + 3H2 → 2Fe + 3H2O b. 4NH3 + 5O2 → 4NO + 6H2O d. 3H2 + 2O2 → 2H3O
irinina <24>

option d

the worths are wrong on the right hand side of the equation, the appropriate equation is over a,b,c.

Five moles of trucks would be____trucks.
umka2103 <35>

carolannpeacock.com:

3.02x10²⁴

Explanation:

To solve this problem we need to use Avogadro"s number: It is the variety of units (normally atoms or molecules, in this instance it"s trucks) had in one mol: 6.023x10²³.

We multiply the offered number of moles times Avogadro"s number:

5 * 6.023x10²³ = 3.02x10²⁴

So 5 moles of trucks would certainly be 3.02x10²⁴ trucks.

Suppose you have actually an Web frifinish who is examining chemistry simply like you are. Your frifinish claims the readjust from liquid water
Aneli <31>
Vaporisation is a physical adjust because it is the readjust of state create from a liquid to a gas. Because vaporisation just changes the state of the substance and also does not change the substance into a totality new one, it is a physical change
