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>

According to reference table adv-10, which is the strongest reducing agent?
Mumz [18]
Li(s)    (answer  A)   
    Li  is  strongest  reducing  agent  because  of  the   lowest  standard reduction  potential.  when  something  is  oxidized, it  reduces  another  substance,  becoming a  reducing.Hence  Lithium  is  strongest  reducing  agent. Reducing  agent   is  stronger  when  it  has  a  more  positive  oxidation potential.

How does the volume of water change the solubility of sodium chloride in simple words?
kupik [55]

Answer:

When sodium chloride dissolves in water to make a saturated solution there is a 2.5 per cent reduction in volume. ... The solubility of salt does not change much with temperature, so there is little profit in using hot water.

Four springs are stretched to the same distance from the equilibrium position. The spring constants are listed in the table. A 2
svp [43]

Answer:

The correct option is;

X, W, Y, Z

Explanation:

The parameters given are;

Spring (S),         Spring Constant (N/m)

      W,                   24

      X,                    35

      Y,                    22

      Z,                    15

The equation for elastic potential energy, E_e, is E_e = 0.5 \times k \times x^2

The above equation can also be written as E_e =\dfrac{1}{2}  \times k \times x^2

Where:

k = The spring constant in (N/m)

x = The spring extension

Therefore, since the elastic potential energy, E_e, of the spring is directly proportional to the spring constant, k, we have the springs with higher spring constant will have higher elastic potential energy, E_e, therefore the correct order is as follows;

X > W > Y > Z
