Explanation:
Eastern Europe is a region that has a negative demographic trends. The population is going down, and there isn't a single country of this region that actually has a positive population growth. There are several reasons as to why this is happening.

Answer:
All dinosaur fossils found by archeologists have been found a few centimeters below the iridium layer. So, the possibility of finding dinosaur fossils above the iridium layer is very slim.
Explanation:
Over 65 million years ago, dinosaurs roamed the earth but were canceled out as a result of an extraterrestrial impact on the earth's crust. Research proved that an asteroid brought the end of dinosaurs as the element iridium was found in the earth (since iridium is abundant in asteroids and not the earth's crust).
Records of fossils found have been between 13 to 60 centimeters below the iridium or the K-T boundary as it is called.
CH4 + 02 → H20 + CO2
balance equation
CH4 + 2O2 → 2H2O + CO2
4 ÷ ( 12 + 4 ) = 0.25 mol
1 : 2
no mole of H2O = 0.25 × 2 = 0.5 mol
mass of H2O = 0.5 × ( 2 + 16 ) = 9g
