<span>Answer: Sodium hydrogen carbonate (NaHCO3), also called sodium bicarbonate, is baking soda. It is also important in controlling the acidity of blood. Potassium bicarbonate is a colorless, odorless, slightly basic, salty substance. Sodium carbonate Na2CO3, is the water-soluble sodium salt of carbonic acid. Potassium carbonate (K2CO3) is a white salt, soluble in water (insoluble in ethanol) which forms a strongly alkaline solution.</span>

The atomic number of nitrogen is 7. How many protons, neutrons, and electrons make up an atom of Nitrogen-15?
earnstyle [38]
<h2><u>Answer:</u></h2>

A nonpartisan iota of Nitrogen has a mass of 18. There are 7 protons in the core of this iota. What number of neutrons, complete electrons, and valence electrons are available  

Nitrogen 15 has a nuclear mass of 15. The mass number is # protons in addition to # of neutrons, so for N-15 mass is 15 and the protons are dependably 7 so there must be 15-7=8 neutrons. N-15 has 7 electrons since it has 7 protons and p = e.

C2d3 has a solubility product constant of 9.14×10−9. What is the molar solubility of c2d3?
shutvik [7]

Answer : The molar solubility of C_2d_3 is 9.67\times 10^{-3}M

Explanation :

The solubility equilibrium reaction will be:

C_2d_3\rightleftharpoons 2C^{3+}+3d^{2-}

The expression for solubility constant for this reaction will be,

Let the molar solubility be, 'x'

K_{sp}=(2x)^2\times (3x)^3

Now put all the given values in this expression, we get:

9.14\times 10^{-9}=108x^5

x=9.67\times 10^{-3}M

Therefore, the molar solubility of C_2d_3 is 9.67\times 10^{-3}M
