Answer:
24.4 amu or g/mole
Explanation:
24 x 0.790 = 19.0 amu
25 x 0.100 = 2.50 amu
26 x 0.110 = 2.86 amu
(Because of the 19.0, the sig figs go only to the 1/10 decimal place)
19.0 + 2.5 + 2.9 = 24.4 amu or g/mole
Answer:
The answer to your question is the second choice
Explanation:
Formula to calculate the heat of any substance
Q cal= mCcal ΔTcal
Formula to calculate the heat of a metal. The heat will be negative because it releases heat.
Qm = -mCmΔTm
Now equal both formula
Qcal = Q m
mCcalΔTm = -mCmetΔTmet
-Solve for Cmet
Cmet = -[mCcalΔTm] / mΔTmet

Explanation:
Air borne pollutants are usually very light particles that are usually carried in the air in the atmosphere. Some of these pollutants can be carried far away and some are found close to their sources.
Some of the factors are:
- Wind pressure: if wind pressure is low, pollutants will not be carried far away. In this situation, the particles will be blown and carried over a short distance from their sources. When wind pressure is very high, pollutants will be carried extensively into farther areas.
- Pollutants can be trapped in snow. In a snowy area, when pollutants reach sky high and enters condensed water in the atmosphere, they can become super cooled into ice and fall back within the same area where they are formed.
- Rain water can also cause pollutants to be dispersed within a short area. Pollutants can mix with rain water and carrier back to the area where they were originally formed.

I’m I’m pretty sure this is a combustion reaction, so that means the products would be CO2 + H2O.
