Group 2 elements are the alkaline earth metals
Answer:
The density of the liquid is 2 grs/ml
Explanation:
To solve this you have to use the formula of density
density = mass/volume ⇒ density = 6 grams/ 3 mililiters ⇒
density = 2 grams/ml (or 2 grams/cm³)
Answer:
Elements
Gold, copper
Compounds
Sodium chloride, Sulphur dioxide, Aluminium oxide,
Mixture
Brass, rainwater, distilled water, sugar solution,muddy water
Explanation:
Answer:
...BY CHOOSING A PROPER INDICATOR, SCIENTISTS CAN MINIMIZE THE DIFFERENCE IN THESE TWO NUMBERS,...
Explanation:
A chemical indicator is an agent or substance which gives a visible sign especially a color change when introduced to a solution of base indicating the threshold of the concentration of acid used in the titration procedure. These indicators include methyl orange, methyl red, phenolpthalein. They give a color change when the concentration of an acid as reached a critical limit in order for the reaction to be stopped. These indicators are involved in acid-base titrations, oxidation- reduction reactions and so on. More accurate results of the volume of the required acid or base is obtained by the introduction of these indicators.
