Answer:
The cylindrical tube can hold 0.215 cubic decimeters of blood.
Explanation:
Diameter of the cylindrical tube = d = 4.5 cm
r = d/2 ,r = 2.25 cm
Height of the cylindrical tube = h = 13.5 cm
Volume of the cylinder = V = 



The cylindrical tube can hold 0.215 cubic decimeters of blood.
Answer:
Compound
Explanation:
The given specie is a compound.
A compound is made up of two or more kinds of atoms/elements joined together in a definite grouping.
- The properties of a compound are distinct and different from those of the individual elements that are combined in its make-up.
- For this given specie, the elements are carbon, hydrogen and oxygen.
- So, this is a compound.
Elements are distinct substances that cannot be split - up into simpler substances. Such substances consist of only one kind of atom
Answer:
2
Explanation:
Mass of water molecule = mass of hydrated salt - mass of anhydrous salt
Mass of water molecule = 5.00 - 4.26 = 0.74g of water molecule.
Number of moles = mass / molarmass
Molar mass of water = 18.015g/mol
No. of moles of water = 0.74 / 18.015 = 0.0411 moles.
Mass of BaCl2 present =?
1 mole of BaCl2 = 208.23 g
X mole of BaCl2 = 4.26 g
X = (4.26 * 1) / 208.23
X = 0.020
0.020 moles is present in 4.26g of BaCl2
Mole ratio between water and BaCl2 =
0.0411 / 0.020 = 2
Therefore 2 molecules of water is present the hydrated salt.

Answer:
The correct answer is C. On the map above, country 6 is Japan and country 2 is China.
Explanation:
Japan is an Eastern Asian constitutional monarchy located in the Pacific Ocean, east of China, North Korea, South Korea and Russia. It extends from the Ochotsk Sea in the north to the East China Sea and Taiwan in the south. Japan is an archipelago of 6,852 islands. The four largest islands are Honshu, Hokkaido, Kyushu and Shikoku, which together account for 97% of Japan's area. Japan has the world's 11th largest population with over 127 million inhabitants.
In turn, China is by far the largest country in East Asia and the world's most populous country with 1.4 billion inhabitants. It is an economic and military superpower and has a permanent seat on the UN Security Council. Chinese civilization is one of the oldest in the world and originated around the Yellow River in northeastern China.
