Answer: Only I and V are true statements concerning chemical equations
Explanation: II subscripts cannot be fractions and coefficients represent the number of moles of reactants and/or products. Subscripts cannot be changed but coefficients can.
<span>A) high to low pressure </span>
The electron configuration for N is 1s^2 2s^2 2p^3, or it could be [He]2s^2 2p^3 but you don’t have the diagram out so I can’t say the definite answer
If a force is applied but nothing happens, then it means that the forces are balanced. Being at such state, <span>equal forces are acting on an object in opposite directions. Hope this answers the question. Have a nice day. Feel free to ask more questions.</span>
If the number of neutrons are changed in an atom, it makes an isotope of that atom. In an atom number of protons is equal to number of electrons.
we can find the number of neutrons by subtracting atomic number from the mass of an atom.
here atomic mass of iron isotope is 55 and we know from periodic table that atomic number of iron is 26 so 55 -26 = 29
there are 29 neutrons.
