Answer: crystalline solid
Explanation: Most ionic compounds exist in crystalline solid form especially at room temperature.
Answer:
Lines of latitude are used to divide Earth into 24 time zones
Explanation:
Answer:
Last week, it was announced that four new elements would be added to the periodic table, a collaboration from researchers in Russia, Japan and the U.S. Elements 113, 115, 117, and 118, which will complete the seventh row, are superheavy elements, that have an atomic number greater than 104.
Explanation:
Answer:
Any binary molecular compound of hydrogen and a Group 6A element above Selenium will be less acidic, so water and dihydrogen sulfide are less acidic in aqueous solution than hydrogen selenide.
Explanation:
Going down in a group increases the atomic radius and a greater atomic radius implyes greater ionic radius.
When ionization takes place in these compounds they yelds protons (hidrogen ion) and an lewis base (anion). The greater the ionic radius the greater its stability, thus the periodic tendency is increaing the acidity of binary hidrogen compounds when going down a group. On the other hand going up a group decreases acidity, so any molecular compound of hydrogen and a Group 6A element above Selenium will be less acidic, so water and dihydrogen sulfide are less acidic in aqueous solution than hydrogen selenide.
Answer:
Ammonium Lauryl Sulfate is a mild surfactant.
Explanation:
Ammonium Lauryl Sulfate is an anionic surfactant. A surfactant is a compound that helps in mixing the matters (solid, liquid, and gas) with one another. It functions by decreasing the surface tension between the two matters. Primarily they are used to mix water with oil. After getting mixed, they help in washing the dirt away.
Ammonium Lauryl Sulfate is a mild surfactant as compared to surfactant as compared to Sodium Lauryl Sulfate in terms of irritation. It is used as one of the components in cosmetics and toiletry formulations. It acts as a surface mixing agent for foaming, wetting and dispersing.
