Etaphase is a stage during the process of cell division (mitosis or meiosis). Usually, individual chromosomes cannot be observed in the cell nucleus. However, during metaphase of mitosis or meiosis the chromosomes condense and become distinguishable as they align in the center of the dividing cell.

Salt is the product formed by a reaction in which _______ atoms of an acid are replaced by the atoms of a metal.
UkoKoshka [18]
<span>Salt is the product formed by a reaction in which the hydrogen atoms of an acid are replaced by the atoms of a metal. The salt is formed as a result of the neutralization of the acid by base, that is the metal or positive ion replace the hydrogen ion in the acid. For instance: NaO + H2SO4 = NaSO4 + H2O. In this example, Na [sodium] has replaced the hydrogen in H2SO4, thereby forming the salt NaSO4.</span>

How can balancing equations support the law of conservation
amm1812

Answer:

detail is given below.

Explanation:

This law was given by French chemist  Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.

Law of conservation of mass:

According to the law of conservation mass, mass can neither be created nor destroyed in a chemical equation.

For example:

In given photosynthesis reaction:

6CO₂ + 6H₂O  → C₆H₁₂O₆ + 6O₂

The given equation is balanced chemical equation of photosynthesis. There are six carbon atoms, eighteen oxygen atoms and twelve hydrogen atoms on the both side of equation so this reaction followed the law of conservation of mass.

If equation is not balanced,

CO₂ + H₂O  → C₆H₁₂O₆ + O₂

It can not follow the law of conservation of mass because mass is not equal on both side of equation.

Is it the power of material evidence that wins, not the authority of experts that
kvasek [131]

Yes, it is the power of material evidence that wins.

  • Evidence used to support or refute a scientific theory or hypothesis is known as material evidence.
  • Evidence is also used by scientists in various contexts, such as when they apply ideas to real-world issues.
  • Whether a person accepts the data as proof depends on their presumptions or views regarding how observations relate to a theory.
  • A creative hypothesis is developed by a scientist and may be refuted by testing it against evidence or established truths.
  • Evidence can refute a hypothesis by demonstrating facts that are at odds with it. In contrast, the presence of evidence does not preclude the possibility of future, undiscovered evidence supporting the idea.

Therefore, it is the power of material evidence that wins, not the authority of experts that

proves an answer in Science.
