What element is in group 1a and higher atomic number than chlorine but lower number than bromine?
Potassium
In an exothermic reaction is the energy of the products higher or lower than that of the reactants?
In an exothermic reaction the energy of the products is less than that of the reactants.
Which has a lower enthalpy ethanol or dimethyl ether?
ethanol
What type of wire can be used to hang a suspended ceiling grid in an indoor swimming pool area where chlorine is present in the air?
Aluminum. Better still, use bromine in the pool, and reactivate it with ozone. You'll use much less chemicals, have much less corrosion, and have orders of magnitude less breathing problems. Bromine has a lower vapor pressure than chlorine does.
What is in Group 1 and has a higher atomic number than chlorine but a lower atomic number than bromine?
This would be Potassium, symbolized as "K". The atomic number is the same as the order of the elements on the period table. That is to say, Hydrogen has the atomic number of 1 because it is first, Helium's atomic number is 2, and so on. Potassium is in group one (groups are the columns) and it is in between Chlorine and Bromine.
Is the melting point of bromine higher or lower than the melting point of chlorine?
The melting point of bromine is -7,2 0C. The melting point of chlorine is -101,5 0C.
Does bromine have a lower boiling point than chlorine?
No, chlorine has a lower boiling point than bromine. Bromine has a boiling point of 332.0 K (58.8 °C, 137.8 °F) Chlorine has a boiling point of 239.11 K (-34.4 °C, -29.27 °F) I have been assigned a homework assignment to the purpose of explaining why this is, although I have no clue... yet. The reason for this is that the London Dispersion Force in Bromine is higher than that of Chlorine. London Dispersion Force depends on the polarizability which consists of two parts: number of electrons in each of these two diatomic molecules and the diffuse cloud (which mainly is the size of the molecule). Because Bromine has more electrons than Chlorine (35 to 17) and Bromine is larger than Chlorine (Period 4 > Period 3). Because of the above, Bromine has higher intermolecular force, London Dispersion Force specifically than Chlorine. Thus, it requires more energy to break the bonds between Bromine molecules than Chlorine molecules. In term of thermodynamics, Bromine has higher boiling point than Chlorine.
Does potassium have a higher atomic number than chlorine and a lower atomic number than bromine?
yes

This element is in group 1 and has a higher atomic number than chlorine but a lower atomic number than bromine?
potato
Why can't iodine be used to displace bromine from sodium bromide?
Iodine is lower in the halogen displacement series than bromine, i.e., iodine is less electronegative than bromine. However both chlorine and fluorine can displace bromine in sodium bromide, as they are more electronegative.
What element in group one has a higher atomic number than chlorine but lower atomic number than bromine?
It could be potassium(K)
Does Sulfur has a lower ionization energy than chlorine?
no sulfur is practically a gas
This element is in group 1 and has a higher atomic than chlorine but a lower atomic number than bromine?
Examination of a Periodic Table shows that the element is potassium.
Is ionisation enthalpy of potassium higher than that of sodium?
The ionisation enthalpy of potassium is lower than that of sodium.
This element is in group 1 and has a higher atomic number than chlorine but lower atomic number than bromine?
Examination of a periodic table shows that the element is potassium.
