Answer is c
Work out the moles of 2H2O: 1.80/ (16+1+1) = 0.1
The moles of 2H2 are the same (0.1)
The Mr of H2 is 2
So the mass needed to produce 1.80g of water is
0.1 x 2 = 0.2
Ultraviolet light is the correct answer
Answer:
volume of gas=101.94L
Explanation:
Suppose given gas follows the ideality nature of gas
PV=nRT
n=35.8/44mol=0.814 mol
P=0.197atm
T=27.5C=300.5K
R=0.0821atm/mol/K
after putting all value we get,
V=101.94L
volume of gas=101.94L
Copper is a mineral and an element essential to our everyday lives. It is a major industrial metal because of its high ductility, malleability, thermal and electrical conductivity and resistance to corrosion. It is an essential nutrient in our daily diet. And, its antimicrobial property is becoming increasingly important to the prevention of infection. It ranks third after iron and aluminum in terms of quantities consumed in the USA.
