Chromium sulfate.
Cr is chromium, and SO4 is sulfate.
Number one: True Number 2: False because hot stars apear as blue-white and cool stars apear as red
HCl is a polar molecule with the hydrogen part being partial positive while the chlorine end being partial negative. This is because hydrogen has an electronegativity of 2.1, and chlorine has an electronegativity of 3.0. This means that chlorine attracted most of the electron cloud of molecule hence is the negative dipole, The dipole moment of HCl is 1.08 D (debyes). A Debye is equal to 3.34 x 10-30 coulomb-meters (C-m). The charge of each molecule is o.176+ for H and 0.176- for the Cl
A homogenous mixture is uniform and thus hard to recognize as a mixture. An example is water.
