The Activation Energy is the energy required before the reaction activates.
So the answer is "The additional energy required for reactions to occur spontaneously"
Answer:
0.36g
Explanation:
Given parameters and conversion to standard unit
To solve this problem we must assume ideality
Volume of N₂H₄ = 350mL = 0.35dm³
Temperature of container = 50°C = 50 + 273 = 323K
Pressure = 885torr;
760torr = 1atm
885torr = 
= 0.86atm
Unknown:
Mass of the compound = ?
Solution:
The mass of the compound can be derived using the expression below;
Mass = number of moles x molar mass
molar mass of N₂H₄ = 2(14) + 4(1) = 32g/mol
To find the number of moles;
PV = nRT
n = 
P is the pressure
V is the volume
R is the gas constant = 0.082atmdm³mol⁻¹K⁻¹
T is the temperature
n = 
= 0.01mole
So,
Mass = 0.01 x 32 = 0.36g
The infant should receive the long-term care in a home environment because it promotes more family interaction and less of a hospital environment.
Answer:
you could disect them or observe what they do by doing things like putting them in a maze or seeing what they do in front of a mirror.
Explanation:
<span>D. evidence that are acquired through use or disuse. Since it is believed that some parts of an organism developed through its need. For example a giraffe got its long neck becuase of reaching for a tree that could produce its food. Another example is the leg of a human which developed because of its need to walk. It was believed that the parts of the an organism did exist or did vanish depending if it was no longer used or it was necessarily needed to survive.</span>
