Answer:3Li+YbCl3=Yb +3LiCl
Explanation:as there are three cl in the first one so to balance them we will put 3before LiCl in order to make Cl balanced now there are 3 Li also so put before Li 3 making it also balanced Yb is balanced already
The number of beats the person have in 1.7 years is 6.7 x 10⁷ beats.
<h3>
Number of beats of the person</h3>
The number of beats of the person is calculated as follows;
n = bt
where;
- b is the beat rate
- n is number of beats
- t is time or duration
b = 75 beats/min
t = 1.7 years = 893520 mins
n = 75 beats/min x 893520 mins
n = 67,014,000
n = 6.7 x 10⁷ beats
Thus, the number of beats the person have in 1.7 years is 6.7 x 10⁷ beats.

ANSWER:
Applied research, because it is solving a problem.
EXPLANATION:
Pure research refers to the systematic study of life aimed at fuller knowledge or a deeper understanding of the theoretical aspects of a phenomenon. On the other hand, applied research is a systematic, empirical study undertaken to generate knowledge for problem-solving in a very broad sense.
Answer : The correct options are, (C), (D) and (F)
Explanation :
Redox reaction : It is also know as an oxidation-reduction reaction in which the electrons transferred between the two species. In this, one species shows oxidation by losing electrons and another species shows reduction by gaining electrons.
Most of the chemical reactions shows the redox reaction. The chemical reactions like, synthesis, combustion, single replacement, decomposition shows the redox reaction.
As, the reactants of Option A, B and E does not shows redox reaction because in these reactions the metals will not displace the another metal ion due to less reactivity of metal.
While the reactants of option C, D and F shows redox reaction because in these reactions the metals will displace the another metal ion easily due to high reactivity of metal.
The reactivity series is shown below.
The balanced redox reactions will be,
Hence, the correct options are, (C), (D) and (F)
Answer:
A) H₂O at 120°C
Explanation:
It is possible to think the higher temperature, the greatest degree of disorder. That is because with a high temperature, vibrations of molecules increases.
In general, at low temperatures, the molecules are in solid state (The lowest degree of disorder), increasing its temperature, molecules becomes in liquids, and, with more temperature, are gases (The greatest degree of disorder).
Thus, the sample that has the greatest degree of disorder is:
<h3>A) H₂O at 120°C</h3>
