Answer:

750 grams is the mass of product and 34.09% is the compositions of the product.

Explanation:

Container 1 , 30% of propane by mass:

Container 2 , 60% of propane by mass:

Mass of mixture in container-1 = 1000 g

Mass of propane in 1000 g of mixture = m

m= \frac{30}{100}\times 1000 g= 300g

Mass of mixture in container-2 = 1200 g

Mass of propane in 1200 g of mixture = m'

m'= \frac{60}{100}\times 1200 g= 720 g

After mixing 1000 grams and 1200 grams of mixture

Final mass of mixtures = 1000 g + 1200 g = 2200 g

Final mass of propane = 300 g+ 720 g = 750 g

Composition of propane after mixing of mixtures :

\%=\frac{750 g}{2200 g}\times 100=34.09\%

Answer:

Solid Osmium transition metal reacts with Oxygen gas to produce solid Osmium tetroxide.

Os(s) + 2O₂(g) -> OsO₄(s)

Explanation:

Osmium tetroxide is another way of writing Osmium (VIII) oxide.

Leaving powdered osmium exposed to air in a room will slowly create osmium tetroxide at room temperature.

Similarly, osmium tetroxide vapor will readily be released from a liquid solution at room temperature.

A corpse discovered in the desert at 5:00 PM was found to have larvae from the blow fly species Phormia regina that had just dev
horrorfan [7]

Answer:

12.19 hours prior to discovery was the corpse placed in the desert.

Explanation:

Heat required for fly eggs to develop into first instar larvae = Exposure\,time\times temperature

From the given,

Exposure time = 16 hrs

Temperature = 27 C

=16\times 27 = 427.2^{o}C

The day time exposed hours is 10 hrs.-(7.00am-5.00pm)

=10\times 37.8 = 378^{o}C

So, the extra heat  = 427.2-378= 49.2

The addition heat divided by average temperature.

Average temperature = 22.4 C

=\frac{49.2}{22.4}= 2.19 hrs

So, the total time exposed is night time hours to day time hours.

= 10+2.19 = 12.19 hrs.

Therefore, 12.19 hours prior to discovery was the corpse placed in the desert.
