Answer: Explanation: Formula of its nitride will be MN. Where is nitride ion on the periodic table? Nitrogen is an element in group 5 of the periodic table. When it forms the nitride ion, it gains three electrons to form a 3- ion: N3− . Is nitride an atom orRead More →
Iron is an essential element for blood production. About 70 percent of your body’s iron is found in the red blood cells of your blood called hemoglobin and in muscle cells called myoglobin. Hemoglobin is essential for transferring oxygen in your blood from the lungs to the tissues. Does hemocyaninRead More →
When forward bias voltage is low, the conduction states on either side of the junction barrier are closely aligned. But as this voltage rises, the conduction states on either side become misaligned. For this reason, the current flow drops as the voltage rises, giving the device a negative resistance differential.Read More →
If there are more than two atoms in the molecule, follow these steps to determine the bond order: Draw the Lewis structure. Count the total number of bonds. Count the number of bond groups between individual atoms. Divide the number of bonds between atoms by the total number of bondRead More →
Treatment with cold sulfuric acid gives red crystals of chromic anhydride (chromium trioxide, CrO3): K2Cr2O7 + 2 H2SO4 → 2 CrO3 + 2 KHSO4 + H2O. On heating with concentrated acid, oxygen is evolved: 2 K2Cr2O7 + 8 H2SO4 → 2 K2SO4 + 2 Cr2(SO4)3 + 8 H2O + 3Read More →
The atomic number for bromine is 35, which means it has 35 protons in its atomic nuclei. A neutral bromine atom would also have 35 electrons. In order for a bromine atom to become a 1− bromide ion, it would have to gain an additional electron. The extra valence electronRead More →
