This is redox reaction because elements change their oxidation states (barium and zinc).
</span>b) Oxidation reaction: Ba⁰ → Ba²⁺ + 2e⁻.
Reduction reaction: Zn²⁺ + 2e⁻ → Zn⁰.
c) Barium is oxidized (increase of oxidation number) and zinc is reduced (decrease of oxidation number).
d) <span> The oxidizing agent is zinc (gain electrons) and the reducing agent is barium (lose electrons).</span>
A scientific law is based on the answers, which are the outcomes of experiments, a number of repetitive tests (in order to make sure the credible results), and observations regarding atmosphere of the Earth, and its life.
While, legal law is based on high ground principle and moral, which are developed to bring order through an armed force. If one looks at it carefully, it is created to monitor human nature, instinctual behavior, and savagery.
Answer:
In order to answer the question, we convert the measurements given to a common base unit. For this case, we use seconds.
A) 0.02 seconds
B) 0.02 teraseconds x (10^12 s / 1 terasecond) = 2x10^10 seconds
C) 2,500 milliseconds x (1 s / 1000 ms) = 2.5 seconds
D) 25,000 nanoseconds x (1 x 10^-9 s / 1 nanosecond) = 2.5 x 10^-5 seconds
So ,The correct answer is option " D "
Cloned material have the same genetic make up because they are formed after one egg cell is fertilized but spilts to form embryos.
