The chemical industry is a very important contributor to the wealth of a country. For example it contributes over 1% to the Gross National Product (GNP) of European countries, which is over 6% of the total GNP produced by all manufacturing industries.
Answer:
phosphorus - least similar to barium
beryllium - most similar to barium
Explanation:
The formula of the chloride formed between barium and chlorine is BaCl2.
Barium is a metallic element and has the valency of +2. Beryllium is also a group two metal with a valency of +2. Hence the compound formed between beryllium and chlorine is BeCl2
Phosphorus is a nonmetal and forms a completely different chloride from BaCl2. The chloride of phosphorus is PCl5 and PCl3. These are least similar to BaCl2
The people of Finland, who are secluded to some degree from the rest of the world by water, develop certain diseases due to the lack of genetic material from other ethnicities and races.
Physical barriers prevent fish from one stream from mating with fish from another stream, leading to a less varied gene pool among those fish. As time passes, the fish become unable to successfully mate with other groups.
A mountain range prevents two types of goat from mating, causing the gene pool to become less varied.<span>

Answer:
because of conduction. The areas to the sides of the light bulb are warmest because of convection. The area directly above the light bulb is warmest because of conduction. The area directly above the light bulb is warmest because of convection
In the given equations for chemical reaction, The Equation No. 2 represents an endothermic chemical reaction.
<h3>What is an Endothermic Chemical Reaction ?</h3>
A reaction which uses energy for the formation of products is known as endothermic reaction.
In the Given Equations,
Equation no. 2 shows the uses of energy with reactants at right hand side which accounts the involvement of energy for the formation of product.
Hence, Equation 2 is a Endothermic chemical reaction.
