The unstable arrangement of atoms that forms momentarily at the peak of the activation-energy barrier is known as the activated complex. Activated complex is termed as a intermediate that is highly unstable and formed during the conversion of reactant into product. That is a short lived intermediate.

How many liters of hydrogen gas at stp are produced from the reaction of 50.0g of magnesium and 75g of hydrochloric acid
ss7ja [257]
Here's how to do it: 

<span>Balanced equation first: </span>
<span>Mg + HCl = H2 + MgCl2 unbalanced </span>
<span>Mg + 2 HCl = H2 = MgCl balanced </span>
<span>Therefore 1 mole Mg reacts with 2 moles Hcl. </span>
<span>50g Mg = ? moles (a bit over 2; you work it out) </span>
<span>75 g HCl = ? moles (also a bit over 2; you work it out) </span>
<span>BUT, you need twice the moles HCl; therefore it is the Mg that is in excess. (you can now work out how many moles are in excess, and therefore how much mg is left over). </span>

<span>So, 2 moles HCl produce 1 mole H2(g) </span>
<span>therefore, the amount of H2 produced is half the number of moles of HCl </span>
<span>At STP, there are X litres per mole of gas (look it up - about 22 from memory) </span>
<span>Therefore, knowing the moles of H2, you can calculate the volume</span>

how many moles of solute are contained in 500.00 milliliter solution that has a concentration of 0.35M
igomit [66]

1.75 moles of Solute or 1.75n.

To find this, you'll need to use the molarity equation which is M = \frac{n}{v}

List the given items to organize better:

M (Molarity) = .35

V (Volume) = 5L [must always be in Liters]

n (Moles) = ?

Now, for the equation, substitute the variables with the given numbers:

.35 = \frac{n}{5}

Isolate the variable by multiplying the volume, 5, onto both sides. This will give you the answer of:

1.75 = n

Hope this helps!
