What is electrophilic addition reaction?
The Electrophilic Addition Reaction is when the attacking species during the addition reaction is"Electrophile", it is called "electrophilic addition reaction". Examine: (+) (-) (+) (-) (+) (-) CH2Br-CH2BràH2C-CH2+BrBr-àH2C=CH2+Br2-
What is an example of harmful?
many things cyanide, cyanide compounds, heavy metals, radioactive material, inert gases such as nitrogen causes asphixia, hydrogen sulphide, clorine, hydrogen chloride, phosphine, phosgene, bacteria or other living things may take up resources. Heaps more
How is a molecule different from a compound?
a molecule of an elemnt has only one element in it[ duh!!] like for eg. oxygen is O2 and hydrogen is H2. a molecule of a compound has more than one element in it, for example water H2O, HCl , NaCl etc etc
How does photosynthesis occur?
Photo synthesis occurs when plants containing a pigment, chlorophyll traps the energy in the sun and uses the energy to create a chemical reaction. Then raw materials, carbon dioxide and water are combined to make sugar(glucose). The left over energy is then stored in a form of starch and carbohydrates, in the leaves, roots and stem. It then releases its main byproduct oxygen.-Zahaa Safodien
Is br2 an oxidizing agent?
Yes, Br2 is an oxidizing agent.
Which one in the following is the strongest oxidising agent between F2 Cl2 Br2 I2?
Fluorine (F2) is the strongest oxidizing agent among the listed halogens. It has the highest electronegativity and is the most reactive due to its small atomic size, making it a powerful oxidizing agent.
What is the answer of this cl2 plus kbr-kcl plus brz?
The correct chemical equation for the reaction is: Cl2 + 2KBr → 2KCl + Br2. The reaction involves chlorine gas (Cl2) reacting with potassium bromide (KBr) to form potassium chloride (KCl) and bromine gas (Br2).
2br- plus so4-2 plus 4h plus -------br2 plus so2 plus 2h2o in this reaction what is the oxidising agent?
S in (SO4)-2 has a charge of +6, in SO2 S has a charge of +4. To go from +6 to +4 you must gain two electrons. The (SO4)-2 is reduced (reduction is gaining electrons). Therefore it reduces the 2br-, so (SO4)-2 is the reducing agent
What is reducing agent in Ca Br2--CaBr2?
In the reaction Ca + Br2 → CaBr2, calcium acts as the reducing agent because it undergoes oxidation by losing electrons to bromine. This results in the formation of calcium bromide (CaBr2).
__CI2+__NaBr—> __NaCI+__Br2?
2 NaBr (aq) + Cl2 (g) → 2 NaCl (aq) + Br2 (aq) Oxidation reduction reaction 2 Br-I - 2 e- → 2 Br0 (oxidation) 2 Cl0 + 2 e- → 2 Cl-I (reduction) NaBr is a reducing agent, Cl2 is an oxidizing agent.
What chemical is oxidized in the following reaction Br2(l) plus 2I-(aq) and rarr 2Br-(aq) plus I2(s)?
Bromine is the oxidizing element.
Which of these species has a longer bond B2 or B2?
Do you meann Br2? there is no B2 diboron species as far as I know. Br2 has a bondl length of 228 pm
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 :)
Chemical formula of bromine water?
bromine water means the liquid formed by dissolving bromine in water. Br2.H2O From M.Swamy
Which molecule has a higher boiling point Cl2 or Br2?
HCL has a higher boiling point compared to HBr This is due to difference in electronegativity. H - 2.1 Cl - 3.0 Br - 2.8 The difference for HCl is 0.9, the difference for HBr is 0.7. The larger the difference in electronegavity means the stronger the bond. Large difference means greater attraction hence more energy is needed to overcome this bond.
Ca plus Br and gt CaBr2 what is the reducing agent?
In this reaction, Br is the reducing agent because it is being oxidized from Br- to Br2, thereby causing the reduction of Ca from Ca to Ca2+.
