What is it called when a liquid becomes a gas a gas becomes a liquid a solid becomes a gas?
The point at which a liquid becomes a gas is the boiling point. The point at which a gas becomes a liquid is still called the boiling point. A solid going straight to gas without passing through a liquid state is called sublimation. Dry Ice solid CO2 is a substance that that sublimes.
What is the formula mass of CO2?
One time the atomic mass of carbon (12 g/mol C) = 12Two times the atomic mass of oxygen (16 g/mol O) = 32Adding up both (totalizing 1*12 and 2*16) gives the molar mass of CO2 = 44 g/mol CO2
What is a chemical change to glass?
The ordinary glass is the silicates of sodium ad calcium with excess amount of silica. Na2SiO3.CaSiO3.4SiO2 The basic components of glass are soda lime and sand it means Na2CO3 , CaCO3 and SiO2 the basic reactions for formation of glass are, Na2CO3 + SiO2 = Na2SiO3 + CO2 CaCO3 + SiO2 = CaSiO3 + CO2 Na2SiO3 + CaSiO3 + 4SiO2 ==1400 celsius== Na2SiO3.CaSiO3.4SiO2 Potash glass cotains potassium instead of sodium. pyrex glass is Na2SiO3.CaSiO3.B2(SiO3)3.SiO2
What is the amount of CO2 produced on burning 12g of carbon in air is?
44 grams of CO2 (1 mol CO2 from 1 mol C if enough oxygen, air, is available)
Does KCl have a higher boiling point than CO2?
Yes, KCl (potassium chloride) has a much higher boiling point than CO2 (carbon dioxide). KCl boils at around 1420 degrees Celsius, while CO2 boils at -78.5 degrees Celsius at standard atmospheric pressure.
Does water or carbon dioxide have a higher boiling point and why?
Carbon dioxide exists as a gas at stp, and water exists as a liquid. Therefore, CO2 has already passed the boiling point, so water has the higher boiling point.
Why does H2O have a higher point than CO2?
H2O (water) has a higher melting point and boiling point than CO2 because of the hydrogen bonds that exist between the water molecules. The hydrogen bonds are strong intermolecular forces (though they are classified as a weak bond), and help to hold separate water molecules together. Thus, the boiling point of water is higher than carbon dioxide, though they are similar in composition and mass.
Which of these substances has the lowest boiling point KCl CO2CH2O?
CO2 has the lowest boiling point among the substances listed. Carbon dioxide (CO2) is a gas at room temperature and pressure, with a boiling point of -78.5°C. In comparison, potassium chloride (KCl) is a solid at room temperature, while formaldehyde (CH2O) is a liquid with a boiling point of -19°C.
Which member of of theawe pairs of substances would you expect to have a higher boiling point a o2 or n2 b so2 or CO2 c hf or hi?
a) O2 would have a higher boiling point than N2 since it experiences London dispersion forces in addition to its higher molecular weight. b) SO2 would have a higher boiling point than CO2 due to its ability to form stronger dipole-dipole interactions and London dispersion forces. c) HF would have a higher boiling point than HI due to hydrogen bonding, which is stronger than the dipole-dipole interactions present in HI.
Which have the highest boiling point mgo and cao or nacl and hcl or co2 and so2?
MgO and CaO have higher boiling points compared to NaCl and HCl, and CO2 and SO2. This is because MgO and CaO are ionic compounds that have stronger electrostatic forces between ions, leading to higher boiling points. NaCl and HCl are also ionic compounds but have lower boiling points compared to MgO and CaO. CO2 and SO2 are molecular compounds with weaker intermolecular forces, resulting in lower boiling points compared to the ionic compounds.
Why does CO2 sublime at -72 degrees C while SiO2 has a melting point of 1713 degrees C?
The difference in melting points between CO2 and SiO2 can be attributed to their molecular structures. CO2 exists as discrete molecules, so sublimation occurs at lower temperatures as the weak van der Waals forces between molecules are overcome. In contrast, SiO2 has a network covalent structure, where each silicon atom is bonded to four oxygen atoms, creating a strong network that requires higher temperatures to break apart and melt.
Why is Co2 gas and Cs2 liquid?
Both CO2 and CS2 are held by Van der Waals' forces but CO2 has a smaller number of electrons than CS2.This leads to weaker forces between the molecules .Therefore, CO2 is a gas while CS2 is a liquid.
Which is heavier CO2 or air and how does the temperature affect it?
Air is heavier than C02, CO2 has a very low boiling point. It is also a pollutant.
Will a fuel with a higher boiling point be a better fuel than one with a lower boiling point?
A low boiling point one would be better as it will use less heat and release Co2 into the air. --------------------------------------------------------------------------------------------------------- Twitter @TrolPie
How do you determine which molecule has a higher boiling point?
Compounds with Hydrogen bonds (Hydrogen bonded to N,O or F) will tend to have stronger bonds thus a higher BP, then the compounds with a stronger polarity determine bond strength, and finally dispersion forces (Molecular mass) So in conclusion if you have ex. HF and CO2 HF has a higher BP because it has a stronger bond than CO2 (it has a hydrogen bond, while CO2's strongest bond is a polar bond)
Why is CS2 a liquid at room temperature whereas CO2 is a gas at room temperature?
CS2 has stronger intermolecular forces, which result in a higher boiling point compared to CO2. CS2 molecules are more polarizable due to the presence of sulfur, leading to stronger London dispersion forces. As a result, CS2 exists as a liquid at room temperature while CO2, being nonpolar, exists as a gas.
