Some gas or bad for climate change and energy
Answer:
neutral
Explanation:
19+3=22
22 protons & 22 neutrons --> neutral net charge
Answer:
See explanation
Explanation:
The question is incomplete, however, I found an example of this question on another site, so, I'm going to explain to you how to do it basing on this example, and then, apply it in your case. In the picture 1, is the example, and picture 2 is the solution.
Now, this type of reaction is known as the "<em>Williamson Ether synthesis"</em><em> </em>and the overall of this, is a reaction that involves an alkoxyde ion with an primary alkyl halide like this:
RO- + R'X ------> ROR' + X-
This is a Sn2 reaction, and it's really fast.
Following the example in picture 1, the result is in picture 2. Hope this can help you.
K₂CrO₄ + PbCl₂ = PbCrO₄ + 2KCl
v=500.0 mL = 0.5000 L
c=3.0 mol/L
M(PbCrO₄)=323.2 g/mol
m(PbCrO₄)/M(PbCrO₄)=n(K₂CrO₄)=cv
m(PbCrO₄)=M(PbCrO₄)cv
m(PbCrO₄)=323.2*3*0.5=484.8 g
Answer:
it is b
Explanation:
b is the quarks for a proton
