3H2+N2→2NH3
here h2 H2 is limiting reagent
6moles of H2 will give 4moles of NH3
V of NH3 produced=22.4*4L
Answer:
This is completely wrong. How could you possibly think like this?
Explanation:
First of all, wearing a mask excessively does not change the oxygen you breathe. It does, however, change <em>how</em> you breathe. You still breathe the same air, but your lungs are different.
Second of all, we do not breathe in more carbon dioxide, because it gets filtered out. (Side note: we don't 'excrete' carbon dioxide, we just filter it out of the air.)
Third of all, "taking medicine & supplements too much results in Stomach & HEART is weak." What medicine have we taken? The vaccine, (of which I will not state my opinions), but other than that, there are no medicines that the general populace has taken.
Lastly, fourth of all, how did we mishandle the pandemic? There are currently 197 million people that have gotten sick worldwide. Do you know how many more people would be sick if we hadn't done what we did?
Please research your beliefs before you post them on any site. Also, please do not post anything politics- or religious- based on Brainly, as that hits nerves for some people, like me.
First, we need to balance the chemical reaction first.
4P4 + 5S8 -> 4P4S10
Next, we determine the limiting reactant based on the given amounts of the reactants and the stoichiometric ratio of the reactants.
Based on 14.62 mol P4, the P4S10 produced is
16.42 mol P4 (4 mol P4S10 / 4 mol P4) = 16.42 mol P4S10
Based on 2.14 mol S8
2.14 mol S8 (4 mole P4S10 / 5 mol S8) = 1.71 mol P4S10
The maximum amount is 1.71 mol P4S10 since S8 is the limiting reactant.
Answer:
When a cation forms, more electrons are transferred to it
Explanation:
Ions can either be cations (positively charged species) or anions (negatively charged species).
Cations are produced when atoms, typically metal atoms, lose their valence electrons to become positively charged.
Anions are produced when nonmetal atoms gain electrons to become negatively charged.
These definitions already eliminate the majority of choices: cations are positively charged ions. Anions are common among nonmetals.
Thinking about nomenclature, charges are represented by a superscript of a number with either a plus (for positive charges) or a minus (for negative charges).
It is false, however, that when a cation forms, electrons are transferred to it. In reality, cations lose electrons rather than gain.
Hello!
To solve this problem we'll use the
Henderson-Hasselbach equation, but first we need the vale for the pKa of Benzoic acid, which is pKa= -log(Ka)=
4,19Now, we apply the equation as follows:
![pH=pKa + log ( \frac{[C_6H_5COONa]}{[C_6H_5COOH]} )=4,19+log( \frac{0,15M}{0,25M} )=3,97](https://tex.z-dn.net/?f=pH%3DpKa%20%2B%20log%20%28%20%5Cfrac%7B%5BC_6H_5COONa%5D%7D%7B%5BC_6H_5COOH%5D%7D%20%29%3D4%2C19%2Blog%28%20%5Cfrac%7B0%2C15M%7D%7B0%2C25M%7D%20%29%3D3%2C97%20)
So, the pH of this solution of Sodium Benzoate and Benzoic Acid is
3,97Have a nice day!
