How much heat is necessary to supply 2 kilograms of aluminum to raise its temperature by 20 ° C?
Answer:
36000J
Explanation:
Given parameters:
Mass of aluminum = 2kg = 2000g
Temperature rise = 20°C
Unknown:
Amount of heat needed for the temperature change = ?
Solution:
The amount of heat needed to cause this temperature rise is given as;
H = m c (T₂ - T₁)
H is the amount of heat
m is the mass
c is the specific heat of aluminum = 0.9J/g°C
Insert the parameters and solve;
H = 2000 x 0.9 x 20 = 36000J
The chemical reaction for the ammonium ion in water is:
NH4+(aq) + H2O(l) ----> H3O+ (aq) + NH3 (aq) Ka = <span>5.60x10^-10
The ammonium ion NH4+ in aqueous form reacts with liquid water forming hydronium ion (aqueous) and aqueous ammonia, with a Ka of 5.60x10^-10.</span>
Answer:
76 ml
Explanation:
The complete question is attached in the image.
The volume of a liquid is the amount of space that the liquid occupies or contains. Since for a liquid, it takes the shape of the container, when measuring the volume, we just measure the space occupied by the liquid in the container.
From the image, when determining the volume, we are to use the value of the lower meniscus. Hence the volume of the liquid is gotten to be 76 ml
