Answer:
NaNO3
Explanation:
sodium= Na
Nitrogen= N
and there's 3 oxygens = O3
Oxygen is an element, symbol O
Magnesium oxide is an ionic compound, formula MgO
The liquid particles would have moved randomly because of the increase in thermal energy. They would move randomly and would be floating in the bottle moving randomly. The liquid would turn into gas form. Meaning that you would have water particles floating in the bottle moving randomly.
Answer:
Water
Explanation:
Solid, liquids, and gases: Water can exist in several states, including ice (solid), water (liquid), and water vapor (gas). color (intensive)
density (intensive)
volume (extensive)
mass (extensive)
boiling point (intensive): the temperature at which a substance boils
melting point (intensive): the temperature at which a substance melts
Answer:
70.8 mmHg
Explanation:
To find partial pressure of carbon dioxide we first find the mole fraction of carbon dioxide
n (carbon dioxide) = 5/44.01 g/mol = 0.11361 mol
n (Helium) = 3.75 g/4 g/mol = 0.9375 mol
The partial pressure of carbon dioxide will be the mole fraction of carbon dioxide multiplied by the total pressure
Partial pressure = 0.11361g/(0.11361g + 0.9375 g)* 655 mmHg
= 70.8 mmHg
