<em>Answer:</em>
- At 60 centigrade, the kinetic energy of the substance will be greatest.
<em>Explanation:</em>
As we know, the kinetic energy of substance is directly proportional to Temperature.
The total Kinetic energy can be calculated as follow
K.E = 3/2 n.R.T
From the equations, it is cleared that Temperature is directly proportional to temperature.
4Ag + 2H2S + O2 -> 2Ag2S + 2H20 i’m pretty sure that’s correct
I believe C is the balanced equation.
Answer:
MgI₂, MgO, PbI₄, PbO₂
Explanation:
For an ionic compound to be formed, it must be neutral, that is the total positive charge must be equal to the total negative charge.
Mg²⁺ and I⁻: The neutral ionic compound requires 1 Mg²⁺ and 2 I⁻ and the resulting empirical formula is MgI₂.
Mg²⁺ and O²⁻: The neutral ionic compound requires 1 Mg²⁺ and 1 O²⁻ and the resulting empirical formula is MgO.
Pb⁴⁺ and I⁻: The neutral ionic compound requires 1 Pb⁴⁺ and 4 I⁻ and the resulting empirical formula is PbI₄.
Pb⁴⁺ and O²⁻: The neutral ionic compound requires 1 Pb⁴⁺ and 2 O²⁻ and the resulting empirical formula is PbO₂.
