The answer is 1, (if it isn't, tell me the answer choices)
Answer:
0.5851 g/cm3
Explanation:
(45.62) ÷ (4.272)³ = 0.5851
Total mass of CaCO3 = 40 amu of Ca + 12amu of C + 16×3 amu of oxygen = 100amu of CaCO3
i.e 100 tonnes of CaCO3 .
mass of CO2 = 12amu of C + 2× 16amu of O = 44 amu of CO2
mass % of CO2 in CaCO3 = (44/100)×100 =44%
i.e
44% of 100 tonnes is CO2.
=44 tonnes of CO2.
therefore, 44% of CO2 is present in CaCO3.
Answer:
No bcz it is insulator it will not conduct electric
Answer:


Explanation:
In this case, since neon could be considered as an ideal gas, the specific volumes at the first and second state are respectively:


Thus, the change in the specific volume turns out:

Which value has sense for the compression.
In addition, the specific enthalpy change just depend on the temperature as it is an ideal gas, therefore, since the process es isothermic:

Best regards.
