How do you know if a compound is solid?
If the melting and boiling points are both below room temp, you have a solid. If they’re both above room temp, the compound is a gas. If the boiling point is above room temp and the melting point is below, the compound is a liquid.
Is BrCl a solid at room temperature?
BrCl is a gaseous compound at room temperature, it has a golden yellow/orange color and it boils at +5 C. ICl is a dark brown liquid/solid at room temperature, which melts at 27 C and boils at 97 C, with a brown vapor. IBr is a dark red solid, which melts at 41 C and boils at 116 C, with a very dark red vapor.
Is iodine a solid?
Iodine is a nonmetallic, nearly black solid at room temperature and has a glittering crystalline appearance. The molecular lattice contains discrete diatomic molecules, which are also present in the molten and the gaseous states.
Is F2 solid at room temperature?
At room temperature, F2 and Cl2 are gases, Br2 is a liquid, and I2 is solid.
Why chlorine is gas but iodine is solid?
At ordinary temperature and pressure, chlorine is because a gas, bromine is a liquid and iodine is a solid because. Intermolecular forces are weakest in chlorine and strongest in iodine.
What type of forces explains why iodine is solid at room temperature whereas Chlorine is a gas?
As iodine has a higher atomic number than chlorine, it also has more electrons in its electron shells. Even though they are divalent molecules, iodine has more electrons per molecule than chlorine which means that iodine has more contact surfaces for intermolecular forces to act on between individual molecules.
Which of the following explanations best describes why chlorine is a gas at room temperature and iodine is a solid?
Explanation: Iodine is present in solid form at room temperature while chlorine is a gas at room temperature because of the difference in intermolecular forces that act on between individual molecules. Iodine has atomic number 53 while chlorine has 17, so iodine has more electrons in its electron shells.
Why is chlorine a gas at room temperature?
In Cl2 there are covalent bonds between the atoms forming simple molecules. There are weak attractions between molecules of Cl2 meaning little energy is needed to break these forces of attraction and therefore Cl2 has a low boiling point.
At what temperature does chlorine become a gas?
How can you tell that chlorine is a gas at room temperature?
Chlorine is a greenish yellow gas at room temperature and atmospheric pressure. It is two and a half times heavier than air. It becomes a liquid at ˆ’34 Â°C (ˆ’29 Â°F).
What does chlorine gas do to you?
Acute exposure at high levels causes dyspnea, violent cough, nausea, vomiting, lightheadedness, headache, chest pain, abdominal discomfort, and corneal burns in addition to the same symptoms of low-level acute exposure. Chronic exposure to chlorine gas can lead to chest pain, cough, sore throat, and hemoptysis.
Can the smell of bleach make you sick?
Bleach has a strong irritating odor and releases chlorine gas that can be harmful to human health. When using it as a disinfectant, it must be diluted to avoid harm to your health.
How do I know if I’ve been exposed to chlorine gas?
Immediate signs and symptoms of chlorine exposure Blurred vision. Burning pain, redness, and blisters on the skin if exposed to gas. Skin injuries similar to frostbite can occur if it is exposed to liquid chlorine. Burning sensation in the nose, throat, and eyes.
Is chlorine dioxide safe to breathe?
* Breathing Chlorine Dioxide can irritate the nose and throat causing coughing and wheezing. * Breathing Chlorine Dioxide can irritate the lungs causing coughing and/or shortness of breath. * Chlorine Dioxide is a HIGHLY FLAMMABLE and REACTIVE gas and a DANGEROUS FIRE and EXPLOSION HAZARD.
Does chlorine dioxide harmful to humans?
At the doses found in supplements, chlorine dioxide can cause serious side effects, including severe vomiting and diarrhea, liver failure, and death. Beware that most chlorine dioxide supplements usually show another ingredient on the label (sodium chlorite).
What Bacteria Does chlorine not kill?
Free chlorine kills most bacteria, such as E. coli 0157:H7, in less than a minute if its concentration and pH are maintained as CDC recommends. However, a few germs are moderately (Giardia, Hepatitis A) to very (Cryptosporidium) chlorine tolerant.
