Answer:Iron is extracted from iron ore in a huge container called a blast furnace. Iron ores such as haematite contain iron(III) oxide, Fe 2O 3. The oxygen must be removed from the iron(III) oxide in order to leave the iron behind. Reactions in which oxygen is removed are called reduction reactions.
Answer:
1.d = 2.70 g/mL
2.d = 13.6 g/mL
4.d = 1896 g / 212.52 cm3 = 8.9 g/cm3

Answer:
V = 1.66mL acetic acid
Explanation:
dilution formula:
V1*C1 =V2*C2
⇒ V1*(6M) = (100mL)*(0.1M)
⇒ V1 =( (100mL) * (0.1M) ) / (6M)
⇒ V1 = 1.66mL acetic acid
The muscular and skeletal systems work together to provide a structural framework for movement... The combined organ systems are sometimes called the musculoskeletal system... When you want to move, signals travel from your brain to your skeletal muscle cells. The muscle cells then contract, or get shorter. Tendons connect the muscles to the bones. As muscles contract, they pull on the tendons which move the bones. Skeletal muscles often work in pairs, as the biceps and triceps of the arm.
