Answer:
Barium iodide
Explanation:
barium iodide is ionic compound. it is formed by the barium metal and halogen element iodine.
Barium is present in group two have two valance electrons.
Iodine is present in group seventeen and have seven valance electrons.
Iodine needed one electron two complete the octet.
That's why two atoms of iodine combine with one atom barium and form ionic compound called barium iodide.
Ba⁺² I₂²⁻
The overall charge is equal cancel the effect of each other and form over all compound neutral.
The volume of a fixed mass of a gas is directly proportional to the temperature
Answer:
A
Explanation:
Acid chloride: --C=O-Cl. Stretch range ~1750-1820cm-1. I'd probably pick
(A) 1800 cm-1, as this value is in the middle (-ish) of that range.
Hence the correct answer is 1800 cm^-1
Answer:
texture
Actually, texture is defined as the physical composition of something, or the look and feel of fabric.
Explanation:
An example of texture is the smooth feeling of satin.
<span>Nuclear reactions have two main types: fission reactions and fusion reactions. When two light nuclei are joined to create a heavier and more stable nucleus, this process is called the fusion reaction. In the fission reaction, the heavy nucleus split into two nuclei with a smaller mass number. In other words, fission is splitting of atoms although not all atoms undergo fission, only few went through normal circumstances (that is a fact). </span>
