Answer:
C
Explanation:
The high specific heat capacity of water means that it takes much more energy to raise the temperatures of water by one (1) degree than land. This means that on a hot sunny day, land temperatures would increase dramatically while ocean temperatures would only rise slightly. Conversely, at night, the land cools rapidly while oceans cool slowly hence the temperatures drop slightly.
1) PV=nRT
P=738.0 mmHg
V=15.5mL=0.0155 L
T=273+25=298 K
R=62.36 L*mmHg*K⁻¹mol⁻¹
n=PV/RT
n=(738.0 mmHg *0.0155 L)/(62.36 L*mmHg*K⁻¹mol⁻¹*298 K)= =0.000616=6.16*10⁻⁴ mol
2) From the equation of the reaction
1 mol CaCO3 gives 1 mol CO2,
so 6.16*10⁻⁴ mol CaCO3 ----> 6.16*10⁻⁴ mol CO2
Molar mass CaCO3 =M(Ca)+M(C)+3*M(O)= 40.1+12.0+3*16.0 =100.1 g/mol
6.16*10⁻⁴ mol CaCO3 * 100.1 g/mol =617*10⁻⁴ g =0.0617 g = 61.7mg

Which statement about schrodingers theory of the atomic model is true?
A. it proved that the nucleus of an atom is positively charged.
B. it was the first theory to discuss the existence of electrons.
C. it explained the odds of finding the position of an electron.
D. it assumed the electron cloud to be heavier than the nucleus.
Answer:
C. it explained the odds of finding the position of an electron.
Explanation:
Erwin Schrodinger formulated the wave equation of electrons. His wave equation highlighted the probability of where an electron can be found or located in an energy level.
The region of maximum probability of where an electron is located is referred to as an electron cloud or an orbital.
Answer:
0.95mol
Explanation:
1mole of NH3 contains 6.02x10^23 molecules
Therefore, Xmol of NH3 will contain 5.70x10^23 molecules i.e
Xmol of NH3 = (5.70x10^23) /6.02x10^23 = 0.95mol
