Is Br2 bigger than i2? I2 has a higher boiling point than Br2. The atomic weights of Br and I are 80 and 127 respectively. Since I2 has higher molecular weight, it has stronger London dispersion forces so it has a higher boiling point than Br2. Why does I2 have such a high boiling point? […]

Why is Aluminium ductile in terms of structure?
Why is Aluminium ductile in terms of structure? The energy is transferred throughout the rest of the metal by the moving electrons. Metals are described as malleable (can be beaten into sheets) and ductile (can be pulled out into wires). This is because of the ability of the atoms to roll over each other into […]
What are 5 uses of neon?
What are 5 uses of neon? Neon is also used to make high-voltage indicators and switching gear, lightning arresters, diving equipment and lasers. Liquid neon is an important cryogenic refrigerant. It has over 40 times more refrigerating capacity per unit volume than liquid helium, and more than 3 times that of liquid hydrogen. What happens […]
What are causes of ocean acidification?
What are causes of ocean acidification? Ocean acidification is mainly caused by carbon dioxide gas in the atmosphere dissolving into the ocean. This leads to a lowering of the water’s pH, making the ocean more acidic. Many factors contribute to rising carbon dioxide levels. What happens during ocean acidification? When carbon dioxide (CO2) is absorbed […]
How electric and magnetic fields are produced?
How electric and magnetic fields are produced? Electric fields are produced by electric charges, and magnetic fields are produced by the flow of electrical current through wires or electrical devices. Because of this, low frequency EMR is found in close proximity to electrical sources such as power lines. What is the difference between electric fields […]
What do the rows mean on a periodic table?
What do the rows mean on a periodic table? Each row represents one period; the period number of an element indicates how many of its energy levels house electrons. Sodium, for instance, sits in the third period, which means a sodium atom typically has electrons in the first three energy levels. How do you identify […]
Why is the Cenozoic Era important?
Why is the Cenozoic Era important? Cenozoic Era, third of the major eras of Earth’s history, beginning about 66 million years ago and extending to the present. It was the interval of time during which the continents assumed their modern configuration and geographic positions and during which Earth’s flora and fauna evolved toward those of […]
What is the difference between average acceleration and instantaneous acceleration?
What is the difference between average acceleration and instantaneous acceleration? Average acceleration is the change of velocity over a period of time. Instantaneous acceleration is the change of velocity over an instance of time. What’s the definition of instantaneous speed? Definition: When the speed of an object is constantly changing, the instantaneous speed is the […]
