Answer:
You need 4 moles of HCl to produce two moles of H2
Explanation:
You can simplify mole and 2 mole into 1 and 2
So how many HCl do you need to make H2?
There are one Hydrogen molecule in Hcl And you need 2 to make a H2
And to make two of each you need to multiply 2 by 2 which is 4
So you need 4 moles of HCl to produce two moles of H2
Hope this helps!
Answer:
Explanation:
No of electrons, n = 20
We need to find the total charge. We can use quantization of electric charge in this case.
Net charge,
q = ne
e is charge on an electron
So, there are of charge in 20 electrons.
Answer:
So I searched it up and got, "They're created by the use of metal salts. ... Metal salts commonly used in firework displays include: strontium carbonate (red fireworks), calcium chloride (orange fireworks), sodium nitrate (yellow fireworks), barium chloride (green fireworks) and copper chloride (blue fireworks)."
WHY WAS I THINKING OF PAINT-
Explanation:
Have a great day though:)
Answer:
dinitrogen tetrachloride, ionic
Explanation:
N2Cl4
N2 should be dinitrogen since the N is nitrogen and the 2 is for 2 of the Ns.
Cl4 (the second part of the compound) should be named like an ion and the prefix. for the prefix: tetra (since there are 4) and chlorIDE since we are naming it like an ion. So Cl4 becomes tetrachloride.
In the end, the compound should be named dinitrogen tetrachloride.
For the second part, I think because Cl is included, and it's charge is -, the bond should be ionic. N can form ionic or covalent bonds.
The bond between N2 and Cl4 is ionic.
A mixture that has component that can be easily separated is a heterogeneous mixture. The parts in the mixture remain physically separate. That means you can tell the parts apart and separate them very easily.
Final answer:- heterogeneous mixture
