Explanation:Br2 , bromine, is a diatomic element, or a molecular element is NOT an example of a compound. Because it is made up of just one element, hydrogen gas (H2) is a molecule rather than a compound. Because it is made up of hydrogen (H) and oxygen (O) atoms, water (H2O) ...
What is the effect of molecular mass on boiling point? Is isopropanol polar? What chemical element has the lowest boiling point? Which chemical element has the highest boiling point? What are the boiling points of the homologous series of alkanes?
Boiling Point: The boiling point of an element is the temperature that provides enough heat energy for it to transition to a gaseous state from a liquid state. For elements that are solid at room temperature, the boiling point is usually very high. Answer and Explanation:1 The boiling point ...
When they need to find out the mass percent composition, how much of the total mass is contributed by each element in the molecule, it is easier to calculate a simple formula than a large formula for a complex molecule.Answer and Explanation: The empirical formula of silver oxide is Ag2 O...
The bromine substance Br2 is a reddish-brown liquid and is never naturally found in its elemental form but rather in inorganic compounds, also known as bromides, and in natural organo-bromine compounds. These are naturally found in soils, salts, air and seawater. Since bromine was discovered ...

TGF-β2 binds to TGFBR2, which then forms a complex with TGFΒR1, and the complex then phosphorylates R-SMADs, enabling the formation of a complex with SMAD4 that can enter the nucleus to transcribe target genes43. We found that knockdown of eitherTGFBR1orTGFBR2promoted senescence in A549...
Sometimes, chemists need to understand the ratio between the atoms of each element in a molecule rather than the full number of atoms or how they are structured. In this case, they use empirical formulas to find this ratio. One reason to use an empirical formula is to find the mass ...
What is the molar mass, in grams, of a mole of an element equal to? What is the molar mass of (NH4)2CO3? Br2 molar mass? What is the correct molar mass of Ag3Po4? What is the molar mass of Ag2SO4? What is the molar mass of trinitrotoluene(TNT), C7H5(NO2)3?
