How do halogen molecules exist?
Halogens are considered to be diatomic molecules. They exist in gas (F2, Cl2), liquid (Br2) and solid phase (Iodine I2).
Which of the following molecules would have the most unsymmetrical attractive forces Br2 H2O HF F2 H2?
H2o
What is the type of intermolecular force present in Br2?
it is a non-polar covalent bond.therefore, the force between the molecules is known as the London dispersion force.
How many atoms of sodium are required to completely react with 5 molecules of Br2 to form the ionic compound sodium bromide?
10
Why cl2 is gass and br2 liquid and I2 solid?
NaCl is ionically bonded with stong electrostatic attractions whereas Cl2 only has weak Van Der Waals' forces acting between the molecules More strength is needed to break NaCl's bonds than CL2's bonds. Therefore, NaCl is solid and Cl2 is a gas Hope this helps :)
How many moles are there in 160g of bromine molecules?
Amount of Br2 = mass of sample / molar mass = 160 / 2(79.9) = 1.00mol
What is the mass of 0.030 mole of Br2?
The mass of 0.030 moles of Br2 is 4.79424 grams, properly rounded to 4.8 grams.
Why dissolve Br2 in methylene chloride and not in water?
because water is highly polar and Br2 is non-polar so the molecules in the water are more attracted to each other. But methylene chloride is non-polar so its molecules are no more strongly attracted to other methylene chloride molecules than they are to Br2 molecules. Since all of the forces are weak, the substance can dissolve.
What is the mass in kg of 3.2L of br2?
9.92kg
Which diotomic molecules are a liquid at room temperature?
Bromine, Br2, is a diatomic molecule that is liquid.
What is the chemical equation of acetylene plus two molecules of Br2?
C2H2 + 2Br2 = C2HEBr2
Molecules which contain 2 atomss of the same element called?
Diatomic molecules. H2, F2, I2, O2, Br2 and so on.
How many particles are in 9.00 moles of Br2?
9 moles of bromine contain 54,2.10e23 molecules.
How do halogen molecules exist?
Halogens are considered to be diatomic molecules. They exist in gas (F2, Cl2), liquid (Br2) and solid phase (Iodine I2).
What atoms exist as diatomic molecules?
there are 7 : H2 N2 O2 F2 Cl2 Br2 & I2
How do you calculate the number of moles of bromine present in 16.0ml of Br2 whose density is 3.12gml?
First convert the volume of the Br2 into grams by using:D=M/VSo we are given that volume=16.0 ml and density=3.12g/ml.M=D*VM=(3.12g/ml)*(16.0ml)=49.92 gThen we use #moles of a substance=#grams present/Formula weight(# of grams of Br2 in 1 mol of Br2)The Formula weight(molar mass) of Br2=2*(79.9 g/mol)=159.80 g/mol Br2#moles of Br2=49.92g/159.80g/mol Br2=.312 moles of Br2 present.
Balance bromine gas and calcium iodide?
Br2 + CaI2 ----> CaBr2 + I2 bromine and iodine are diatomic molecules
