The forelimb
Explanation:
The skeletal system is made up of the bones of the human body which provides protection for vital organs in the body. It also serve as a surface for the attachment of muscles through which movement is coordinated.
There are different bones in the body.
The forelimb is made up of the:
- Scapula
- Humerus
- Ulna
- Radius
- Carpals
- Metacarpals
These bones are jointed together to form our arm. If an archaeologists digs up any of the bones, he/she has unraveled some of the bones of the forelimb.

Answer: 2-Benzyloxyethanol is produced reaction in the fig. below.
Explanation:
Answer:
1) BaCl2+K2So4 → BaSo4+ KCl
2) Zn+AgNO3 → Zn+NO3+Ag
Answer: This chemical reaction is a neutralization reaction between the Milk of Magnesia and the HCl from the stomach. The balanced equation is Mg(OH)2 (s) + 2 HCl (aq) → MgCl2 (aq) + 2 H2O (l)
Explanation:
The reaction between the HCl and the Mg(OH)2 is a neutralizacion reaction , because the HCl is a strong acid and the Mg(OH)2 is a weak base, then both react and the pH of the medium will increase, so the stomach trouble will dissapear.
Mg(OH)2 (s) + 2 HCl (aq) → MgCl2 (aq) + 2 H2O (l)
Magnesium hydroxide is a weak base due to its very limited solubility in water. This property is a great advantage when treating the excess of HCl in the stomach, because the Mg(OH)2 molecule does not dissociated easily until it reacts with the hydrogen ion, H+ of the HCl. So the effect of the Mg(OH)2 will last longer until the annoyance dissapear.
