What do you mean by that Oh wait do you mean like 2×2=4 or 2+2=4 something like that maby?? I am still confused?? XD
Answer:
the discovery will always need to be tested more where if you're investigating you should already be in a more controlled environment
Answer: 45.038
Explanation: 2.016 H (2*1.008) + 15.999 O (1*15.999)
The oxidation state of Chromium chloride (III) is +3
How can we find the answer?
First of all write down what you know about the molecule:
1: The molecule hasn't got an electric charge (is not an ione), this means that either positive and negative charges of its atoms are balanced (we have the same number of positve and negative charges)
2: Since it's a salt, where the metal is chromium and the non metal is the alogen Chlorine, we know that the negative charge belogns to the non metal element because of its elettronegativity, therefore the positive charge belongs to the metale element (chromium).
3: when chlorin forms binary salts its oxidation state is always -1 (you can find out this info in a periodic table)
In <span>CrC<span>l3</span></span> we have 3 chlorine atoms where each of them carrys 1 negative charge, so the total amount of negative charges is -3
Since the charges are balanced, the question is: Which is the positive charge that Chromium must carry in order to balance 3 negative charges?
The answer comes out to +3
Answer:
74.6 g
Explanation:
The computation of the number of grams produced at the time when 32.0 grams of C react is shown below:
As we know that
But before that we need to find out the moles of c i.e carbon which is
= 2.66 mol
As we know that
1 mol of C produces 1 mol of CO
So, for 2.66 mol, the mass of CO is
= 74.6 g
Basically we applied the above equation so that we can reach to the answer
