Find the final equilibrium temperature when 15.0 g of milk at 13.0 degrees c is added to 148 g of coffee with a temperature of 8
user100 [1]

According to zeroth law of thermodynamics, when two objects are kept in contact, heat (energy) is transferred from one to the other until they reach the same temperature (are in thermal equilibrium). When the objects are at the same temperature there is no heat transfer.

So, at equilibrium, q_{lost}=q_{gain},  q_{lost}= q_{milk} + q_{coffee}

q=m×c×T, where q = heat energy, m = mass of a substance, c = specific heat (units J/kg∙K), T is temperature

q_{lost}= (15X13X4.19)+(148X88.3X4.19), (15+148)X4.19XT_{final}=(15X13X4.19)+(148X88.3X4.19)

T_{final}= 81.37 ° C

To show the electron configuration for an atom, when would it be better to use an orbital notation than to use a written configu
VikaD [51]
The answer is <span>D.when the aim is to show electron distributions in shells. This is because there are some instances when elements don't possess a regular or normal electron configuration. There are those who have special electron configurations wherein a lower subshell isn't completely filled before occupying a higher subshell. It is best to visualize such cases using the orbital notation.</span>

Calculate the [oh] for 0.46 Hcl
Bad White [126]

Answer:

2.17 e -14

Explanation:

A strong acid like HCl ionize 100 % in water so [H3O+] = 0.46 M

[OH-] = Kw /  [H3O+]

        =  1.0 e -14 / 0.46

         = 2.17 e -14

Explain how q reaction would be affected
MakcuM [25]
Q or the Reaction Quotient is the interaction between the reactants and products in a given chemical reaction. The value of Q should be compared to the value of K (which is the value of the reaction at equilibrium) in order to determine which way the reaction should move to achieve equilibrium.If Q is already equal to K, then this indicates that the reaction is in equilibrium. If Q>K, then the reactants are converted to products; If Q<K, then the products are converted to reactants. Either way, the reaction proceeds to move towards equilibrium after some time.
