I think it’s c bc it makes more sense
Answer:
P=19.32g/cm³
Explanation:
m=9.66g
v=0.5cm³
P=mass/volume (density formula)
=9.66/0.5
=19.32g/cm³
Answer:
The size of an isolated atom can't be measured because we can't determine the location of the electrons that surround the nucleus. We can estimate the size of an atom, however, by assuming that the radius of an atom is half the distance between adjacent atoms in a solid. This technique is best suited to elements that are metals, which form solids composed of extended planes of atoms of that element. The results of these measurements are therefore often known as metallic radii.

Answer:
The equilibrium will shift to the right.
Explanation:
- Le Châtelier's principle states that when there is an dynamic equilibrium, and this equilibrium is disturbed by an external factor, the equilibrium will be shifted in the direction that can cancel the effect of the external factor to reattain the equilibrium.
For the reaction: <em>CH₄ + NH₃ + 1.5O₂ ⇄ HCN + 3H₂O.</em>
<em></em>
Adding NH₃ to the reaction:
- Adding NH₃ will increase the concentration of the reactants side, so the reaction will be shifted to the right (products) side to suppress the increase in the concentration of NH₃.
Answer:
They don't have values there because they aren't on the pauling scale of electronegativity, as they don't form any compounds with other elements.
