According to their system of classification, the Sun is known as a yellow dwarf star. This group of stars are relatively small, containing between 80% and 100% the mass of the Sun. So the Sun is at the higher end of this group.
Answer:Yogurt is made up of a bacteria known as lactobacillus acidophilus.
Explanation:
The elements that are expected to have similar characteristics with sulfur are oxygen, selenium, tellurium and polonium.
<h3>Elements in the same group</h3>
Elements in the same group in the periodic table share similar chemical characteristics.
<h3>Elements in the same group as sulfur</h3>
The elements found in the same group as sulfur, that share similar chemical characteristics include;
- oxygen,
- selenium,
- tellurium and
- polonium.
Thus, the elements that are expected to have similar characteristics with sulfur are oxygen, selenium, tellurium and polonium.

The only reaction that will most likely take place based on the activity series is; C: Ba + Na₂CO₃
<h3>Activity Series</h3>
From the activity series given, we can say that during a displacement reaction, the more reactive metal will always displace the lesser reactive metal from a compound.
Let us look at each of the given options;
A) Ag + FeCl₃
From the activity series, Silver(Ag) is less reactive than Iron(Fe) and as such Silver cannot displace iron from its' compound.
B) Zn + CaO
Zinc (Zn) is a less reactive metal than Calcium (Ca), so it cannot cannot displace Calcium from its' compound.
C) Ba + Na₂CO₃
Barium (Ba) is a more reactive metal than Sodium (Na), and therefore Barium will displace sodium from its compound in a displacement reaction.
D) Cr + KNO₃
Chromium (Cr) is a lesser reactive metal than Potassium (K), and it therefore cannot displace Potassium from its compound.
Complete question is;
Which reaction will most likely take place based on the activity series? Li > K Ba > CaNa > Mn > Zn > Cr> Fe> Cd Ni > H > Sb > Cu > Ag > Pd > Hg > Pt
A. Ag + FeCl₃
B. Zn + CaO
C. Ba + Na₂CO₃
D. Cr + KNO₃
