Answer:
28.16 °C
Explanation:
Considering that:-
Heat gain by water = Heat lost by metal
Thus,
Where, negative sign signifies heat loss
Or,
For water:
Mass = 165 g
Initial temperature = 28 °C
Specific heat of water = 4.184 J/g°C
For metal:
Mass = 4.00 g
Initial temperature = 75 °C
Specific heat of water = 0.600 J/g°C
So,
<u>Hence, the final temperature is 28.16 °C</u>
They All are Living things.
A precipitate will form since BaSO₄ is insoluble in water.
Answer:
1.23 moles
Explanation:
Ideal gas law
PV = n RT R = .082057 L-atm/mol-K
25 C = 298.15 K
12 (2.5) = n (.082057) (298.15) n = 1.23 moles
Not A because
2-Pentyne, an organic compound, is an internal alkyne. It is an isomer of 1-pentyne, a terminal alkyne
Is B because
DescriptionPentenes are alkenes with chemical formula C ₅H ₁₀. Each contains one double bond within its molecular structure.
