calcium ca
Explanation:
We can see here that the only element that is on the same group (column) as Ba (Barium) is Calcium (Ca).
Answer:
Explanation:
Molal freezing point depression constant of butanol Kf = 8.37⁰C /m
ΔTf = Kf x m , m is no of moles of solute per kg of solvent .
mol weight of butanol = 70 g
235.1 g of butanol = 235.1 / 70 = 3.3585 moles
3.3585 moles of butanol dissolved in 4.14 kg of water .
ΔTf = 8.37 x 3.3585 / 4.14
= 6.79⁰C
Depression in freezing point = 6.79
freezing point of solution = - 6.79⁰C .

The Rock Cycle<span> is a group of changes. Igneous </span>rock<span> can change into sedimentary </span>rock<span> or into metamorphic </span>rock<span>. Sedimentary </span>rock<span> can change into metamorphic </span>rock<span> or into igneous </span>rock<span>. Metamorphic </span>rock<span> can change into an igneous or sedimentary </span>rock<span>. Igneous </span>rock<span> forms when magma cools and makes crystals.</span>
