Answer:
911.36mmhg
Explanation:
1 torr is almost equivalent to 1mmhg.but to convert from atm to mmhg,multiply by 760
He can do this by finding the all the characteristics of copper,
this includes size, density, color,malleable, and see if its a conductor of heat
Direct Combination Reaction : The reaction in which two or more substances combine to form a single substance is called direct combination reaction. Synthesis Reaction: The reaction in which two or more elements combine to form a compound is called direct combination reaction.

Answer:
D. Kingdom Fungi includes organisms that get energy by absorbing materials in their environment.
Explanation:
Organisms in the domain Eukarya are characterized by the possession of a well defined NUCLEUS in their cells. Kingdoms in this domain include animalia, plantae and fungi.
- Kingdom animalia contains multicellular organisms that are strictly heterotrophic i.e. cannot synthesize their own food, hence, rely on other organisms for nutrition.
- Kingdom plantae contains multicellular organisms that are capable of movement but not independently i.e. they cannot move from their fixed positions.
- Kingdom Fungi includes organisms that get energy by absorbing materials in their environment via a structure called MYCELIUM.
the mass of ice taken = 10 g
the mass of water = 250 g
initial temperature of water = 20 C
the final temperature of water = 16. 8 C
specific heat of water = 4.18 J/g*K
the heat absorbed by ice to melt = heat loss by water
heat loss by water = mass X specific heat of water X change in temperature
heat loss by water = 250 X 4.18 X (20-16.8) = 3344 Joules
heat gained by ice = 3344 J
heat gained by ice = enthalpy of fusion X moles of ice
moles of ice = mass / molar mass = 10 / 18 = 0.56 moles
enthalpy of fusion = 3344 / 0.56 = 5971.43 J / mole
