Answer:
Explanation:
2 mole x 6.023x 10^23atoms/mole =12.04 atoms
The first one is not balanced
H=2. H=2.
O=2. O=1
The second one is balanced
Na =6. Na=6
S=3. S=3
<span>If the decomposition of H2O2 is first order, then
rate=k*[H2O2], and k=rate/[H2O2]
In this case k=(4.83 x 10-6 M/s)/(0.15 M)
k=3.22 x 10-5 s^-1</span>
In terms of a deeper scientific reason, I am not sure, but the basic reason is quite simple. "Mud" tends to look like a mix between a solid, dirt, and a liquid, water or some other liquid. Since it is, in fact, a cross between a solid and a liquid, it has properties of both. It has certain physical and visual properties that only a solid would have, such as texture and opaqueness, but it also has physical properties of a liquid. Since it leans more towards the liquid side than the solid side, we say mud "flows" rather than saying that it "rolls" or "bounces".
I think it is B for the answer
