allsm [11]4 years ago
3 0

Answer: Option (C) is the correct answer.

Explanation:

A chemical change is a change which brings change in chemical composition of a substance or reactant(s).

Thus, we can say the due to change in composition we get a new product.

For example, Na + Cl \rightarrow NaCl

That is, NaCl is the new product formed.

Hence, we can conclude that common to all chemical changes is that a new substance is produced.

Which group of extremophiles does thermus aquaticus belong to
Elan Coil [88]

Answer:

The correct answer is thermophiles.

Explanation:

Thermus aquaticus are heat resistant bacteria because these bacteria can survive under adverse environmental conditions like high temperature.

These bacteria belong to one of the most heat-loving groups of extremophiles that are thermophiles. Thermophiles are present in volcanic soil, geysers and around deep-sea vents where the temperature is extremely high.

Thermus aquaticus bacteria is used to manufacture an enzyme called Taq DNA polymerase, which is heat resistant and also an important factor in molecular biology.

Sometimes you are given a measured amount of two or more reactants and asked how much product can be formed. Explain what steps
Westkost [7]

Explanation:

To solve this problem, follow these steps;

  • Obtain a balanced equation of the reaction and familiarize with the reactants and products.
  • Find the number of moles of the reacting species since they are the known matter in terms of quantity.
  • From the number of moles, determine the limiting reactant.
  • The limiting reactant is the one given in short supply.
  • Such reactant determines the extent of the reaction.
  • Compare the moles of this specie to that of the products using the balanced equation.
  • Obtain the mole of the desired product and find the mass or desired quantity.
  • simply work from the known specie to the unknown
