Answer:
Explanation:
Sn(WC)2
if it is tungsten carbide this should be correct but there are many versions of carbide
Sn(MC2)2
could also be possible
the 2 next to MC should be a subscript
The answer is the last option. Electronegativity is the measure of the attraction that an atom has for electrons involved in chemical bonds. It relates to covalent bonds where electrons are shared. The Pauling scale is the most used.
Answer:
The temperature of the entire water sample after all of the ice has melted is 31.4 °C
Explanation:
This question relates to the first law of thermodynamics which states that energy can not be created nor destroyed but changes from one form to another
The specific heat capacity of water is 4.2 J/(g °C)
The latent heat of fusion of ice = 333.55 J/g
Mass of the ice = 21.5 g
Mass of the water = 500 g
Initial temperature of water = 31 °C
Therefore
Heat gained by the ice = 21.5 g × 333.55 J/g = 7162.725 J
= 500×4.2×(T-31)
Or T = 31.4 °C
Therefore the temperature of the entire water sample after all of the ice has melted is 31.4 °C
A volcanic arc is a chain of volcanoes formed above a subducting plate, positioned in an arc shape as seen from above. Offshore volcanoes form islands, resulting in a volcanic island arc.
