Answer:  TRUE

Explanation:  Transition elements are those which have electrons in the d orbitals in their outermost valence shell. They are also known as d block elements.

Thus Copper, Iron, Nickel etc are d block elements because their electrons are in the d orbital as shown-

Copper (Cu) = [Ar] 3d10 4s1

Iron (Fe) = [Ar] 3d6 4s2

Nickel (Ni) = [Ar] 3d8 4s2

Thus as shown in the electronic configuration above, the given stateent is true.

Explain the difference between complete dominance and codominance.Give an example of each one in order to explain it.
Ira Lisetskai [31]
In complete dominance, only one allele in the genotype is seen in the phenotype. In codominance, both alleles in the genotype are seen in the phenotype. In incomplete dominance, a mixture of the alleles in the genotype is seen in the phenotype.

1. A scientific hypothesis can become a theory if ______.
Rus_ich [418]
<span>1. A scientific hypothesis can become a theory if the hypothesis is tested extensively and competing hypothesis are eliminated. A scientific hypothesis is a proposed explanation made on the basis of reasoning without any assumption. For hypothesis to be termed a scientific hypothesis, it has to be something that can be supported or refuted through carefully crafted experimentation or observation.

  2. A preliminary untested explanation that tries to explain how or why thing happen in the manner observed is a scientific hypothesis. A primary trait of a hypothesis is that something can be tested and that those tests can be replicated. A hypothesis is often examined by multiples scientists to ensure the integrity and veracity of the experiment. The process can take years, and in many cases hypothesis do not go any further in the scientific method as it is difficult to gather sufficient supporting evidence. </span>

What are the number of ions Fe^+2 and Fe^+3 in Fe7(CN)18?​
andreev551 [17]

Answer:

2x + 3y = 18 sum of charges of the iron ions must be +18 to balance 18 CN- ... y = 4 so there are 4 Fe3+ ions and (7–4) = 3
