Answer: 0.00867 moldm-3
Explanation:
Since the reaction is 1st order,
Rate of reaction=∆[A]÷t
0.646-0.0146/72.8= 0.00867
Remember that in a first order reaction, the rate of reaction depends on change in the concentration of only one of the reaction species, A in the problem above.
<span>Thin, flattened, and typically curved bones, such as the ribs or sternum, form falt bones.
The two main functions of flat bones are protection or provide a large surface for musular attachment.
These are the flat bones of the human body: in the skull, parietal, frontal, occipial, lacrimal, nasal and vomer; scapula; sternum; rib and hip.

Since the given solubility is 350 ppm, convert it first with fraction of solubility. by dividing the solubility with 10^6
S = 350 / 10^6
s = 3.5 x 10^-4
the multiply it to the total solution to calculate the amount of substance present
m = ( 3.5 x 10^-4 ) ( 1.01 )
m = 3.535 x 10^-4 g of the substance present
4- when you cook the egg because when you coook the egg it is no longer raw and you cant re do it so there for it is a chemical chabge
He answer in here is b.7.5 cubic meters. We know this when we do the following calculation:
<span>(10 m^3) x (1 / 1.5) x ((32 + 273) / (273)) = 7.5 m^3
