Yes a red blood cell placed in a sline solution shrinks because of the process of osmosis.
Answer:
Check explanation section.
Explanation:
Yes, that is true. Sodium with chemical symbol Na belongs to the group 1 on the periodic table. Group 1 elements are known as Alkali metals. Other elements in the group are Caesium, lithium, Rubidium, francium and potassium.
Neon belongs to the noble gas of group 8/0.
Sodium is very reactive and and good conductor of electricity. Sodium reacts with water for the production of hydrogen (NB: this reaction is vigorous).
2Na(s) + 2H2O ------------> 2NaOH + H2(g).
They can react with nonmetals such as the halogens. For instance;
Na + Cl2 -------------------------------> 2NaCl.
Sodium is ductile and have low melting point( but high compared to neon).
Neon is not active chemically and it has no odour and no color
A substance intentionally added that affects the nature and quality of food is called food material.
There are seven most important components in food materials: carbohydrates, fats, proteins, vitamins, mineral salts, water and fibre.
Some other examples of food material:
1) Food dyes are chemical substances who gives artificial color to the food.
It is important to know which food dyes are in food because some dyes can cause allergic reactions or cancer.
2) Emulgators are used as an additive to food to emulsify some food.
Emulsions are two or more liquids that are normally not mixable. For example egg yolk and mayonnaise.
