Sometimes when an animal dies and its body decays, it can leave an imprint in the sediment. If this imprint fills in with minerals from sediment and groundwater, it can harden to form a fossil. This fossil is called a cast fossil. The fossilized imprint is called a mold fossil. Bzhzzjskdkzkzbdzvdhdjdjdjdjdjd
Answer:
the molar mass is 40 and the metal is Calcium
Explanation:
X + H2SO4=X2SO4 + H2
The mole ratio is 1:1
no of mole of H2SO4= conc(M) × Vol(L)
=0.1×0.5
=0.05 mol
from the balanced chemical equation of the reaction
no of mole of 'X' = no of mole of H2SO4
thus no of mole of X=0.05 mol
Also, no of mole=mass/molar mass
molar mass of 'X'=mol/mass
=2/0.05
=40

a balloon containing 1,000L of gas at 50. C and 760 mmHg rises to an altitude where the pressure is 380mmHg and the temperature is 10. C, what is the new volume of the balloon (in L)?
PV/T =P'V'/T'
380 XFIRST, ALWAYS ALWAYS, ALWAYS CHANGE TEMP IN C TO TEMP IN K
50C =50+273K =323K
10C= 10+273 =283
now PV/T =P'V'/T')
so
760 X 1/323 = 380 X V'/283
so
V' =760 X1 X283/(323X380)
V' = 1.75 L
