One: looks to be correct for both answers. Certainly the first one is. The second depends on your other choices. But military use is one.

Two: is correct. Pd has (in this case) an atomic mass of 114 and its number is 46

Three: Even with my slop numbers, 4.98  is the answer (although I get 4.99 but again, my numbers are pretty sloppy).

Four: Slop numbers say 78.3, but 78 is the right answer.

Five: Slop numbers agree with Al2S3. I think that's D

They are all correct. Very Fine Work.

What kind of chemical change do you think occurs when a banana peel turns brown in the open air?
Alisiya [41]
Rotting, and ageing. The banana peel ages faster in open air, and therefor begins to rot. Brow peels don't mean that the banana is rotted, however, it is a sign that it may begin to rot soon.

What mass of NaCl is dissolved in 150 g of water in a .050<br> msolution?
mart [117]

Answer:

0.4383 g

Explanation:

Molality is defined as the moles of the solute present in 1 kg of the solvent.

It is represented by 'm'.

Thus,  

Molality\ (m)=\frac {Moles\ of\ the\ solute}{Mass\ of\ the\ solvent\ (kg)}

Given that:

Mass of solvent, water = 150 g = 0.15 kg ( 1 g = 0.001 g )

Molality = 0.050 m

So,

0.050=\frac {Moles\ of\ the\ solute}{0.15}

Moles = 0.050\times 0.15\ mol= 0.0075\ mol

Molar mass of NaCl = 58.44 g/mol

Mass = Moles*Molar mass = 0.0075\times 58.44\ g = 0.4383 g
