Alum crystals turn into a solid mass of anhydrous alum
The atomic radius of potassium is larger than that of sodium. This is due to the increase in atomic size as you move down a group in the periodic table, with potassium being located below sodium.
Potassium has a larger atomic radius compared to sodium. This is because as you move down a group in the periodic table, the atomic radius increases due to the addition of more energy levels. In the case of potassium and sodium, potassium is located below sodium in the same group, resulting in a larger atomic radius for potassium.
Hydrated lime and slaked lime are both forms of calcium hydroxide, but they differ in how they are produced. Hydrated lime is made by adding water to quicklime, while slaked lime is made by adding water to lime putty. In terms of properties, hydrated lime is a dry powder that is more stable and easier to handle, while slaked lime is a wet paste that is less stable and can harden over time. Hydrated lime is commonly used in construction, agriculture, and water treatment, while slaked lime is often used in traditional building materials and as a chemical reagent. Overall, hydrated lime is more versatile and widely used compared to slaked lime due to its easier handling and broader range of applications.
Calcium has a larger atomic radius than magnesium and a smaller atomic radius than potassium. This trend is due to the increase in number of protons and electrons as you move across the period on the periodic table from magnesium to calcium to potassium.
potassium atom has a bigger atomic radius and its valence electron located at 4th shell with more shielding effect so lower ionization energy required so more free electrons so better conductivity for electricity
Heating crystals of CuSO4 pentahydrate in a test tube will cause the water molecules trapped in the crystal lattice to evaporate, leaving behind anhydrous CuSO4 crystals. The color change observed will be from blue (for the hydrated form) to white (for the anhydrous form).
Fail! But thank you for trying....
A table.
Yes. A pie chart is used to visually compare the parts of the whole.
The formula of the hydrated form is MgSO4·7H2O. To find this, calculate the molar mass of MgSO4 (120.37 g/mol) and compare it to the molar mass of MgSO4·7H2O (246.47 g/mol). The difference in mass represents the mass of water lost upon heating, which is 126.1 g/mol (246.47 g/mol - 120.37 g/mol). Dividing the mass of water lost by the molar mass of water (18.015 g/mol) gives us the number of water molecules in the hydrated form.
A table or a chart.
Bar charts or histograms.
You could use a chart. You could also lay them out in a table and be able to see them clearly that way and compare them.
The atomic radius of potassium is larger than that of sodium. This is due to the increase in atomic size as you move down a group in the periodic table, with potassium being located below sodium.
A balance or a scale can be used to compare the masses of two objects. By placing the objects on either side of the balance or scale, you can visually determine which object has a greater or lesser mass.
Potassium has a larger atomic radius compared to sodium. This is because as you move down a group in the periodic table, the atomic radius increases due to the addition of more energy levels. In the case of potassium and sodium, potassium is located below sodium in the same group, resulting in a larger atomic radius for potassium.
A pie chart is used to compare facts with each other visually in the form of a circle whereas pi is used for example in finding the area of a circle.
