The correct answer is option B. The most dense phase of matter is the solid phase and the least dense are gases. However, there is an exception. Water is the exception. Solid water or ice is less dense than the liquid phase therefore it floats on liquid water.
Answer:
72.22 g
Explanation:
975 mL Mercury× 13.5 g/mL = 72.22 g
Answer:
98.6 g/mol.
Explanation:
Equation of the reaction
HX + NaOH--> NaX + H2O
Number of moles = molar concentration × volume
= 0.095 × 0.03
= 0.00285 moles
By stoichiometry, 1 mole of HX reacted with 1 mole of NaOH. Therefore, number of moles of HX = 0.00285 moles.
Molar mass = mass ÷ number of moles
= 0.281 ÷ 0.00285
= 98.6 g/mol.
Answer:
The amount of movement of tectonic plates in the area
Explanation:
The population density vary across the countries
Japan(127m), Philippines ( 103m), Indonesia (267m).
The volcanoes in Indonesia are among the most active of the pacific Ring of Fire along the north east island
Answer:
105m/3hourz
Explanation:
35 miles per hour, so 3 hours
35x3=105 per 3 hours
