Answer:

Ionic bonding happens when an atom of an element gives one or more of its electrons to the other element's atom..it usually takes place between metal and non metal atoms...like in NaCl, Na gives its valence electron to chlorine and completes its own octet. Chlorine accepts the electron and completes its own octet too...but now both the atoms have an opposing charge and hence they attract each other to form an IONIC bond.

Ionic bonds are the strongest of the bonds...here complete transfer of electrons takes place unlike covalent bonds.

The density of water is 62.4 lb/ft3. If a swimming pool holds 10,000 gallons of water, the weight of water in the pool is lbs. (

Semenov [28]

In this case, you are given the water density (62.4lb/ft3) and the water volume (10,000 gallons). But the unit used in the density and gallon is different, so you need to convert it. The calculation would be:

mass= density * volume
mass= 62.4 lb/ft3 * 10,000 gallons * (231 inch3/gallon) * (1 ft3/ 1728 inch3)
mass= 83,416.66 lbs= 81417 lbs

The pH of saliva is normally in the range of 6.4 to 7.0. However, when a person is ill, the person's saliva becomes more acidic.

aleksley [76]

Answer:

Concentration of hydrogen ion, $[H^+]=5.0118*10^{-6} M$

Explanation:

pH is defined as the negative logarithm of hydrogen ion's concentration.

The lower the value of pH, the higher the acidic the solution is.

The formula for pH can be written as:

$pH=-log[H^+]$

Given,

pH of the saliva of Marco = 5.3

To calculate: Hydrogen ion concentration in the saliva

Thus, applying in the formula as:

$pH=-log[H^+]$

$5.3=-log[H^+]$

So,

$log[H^+]=-5.3$

$[H^+]=10^{(-5.3)}$

$[H^+]=5.0118*10^{-6} M$

What mass, in grams, of chlorine gas (Cl2) is contained in a 12.5-liter tank at 27.0 degrees Celsius and 2.85 atmospheres? Show

nata0808 [166]

PV = nRT
P is pressure, V is volume, n is number of moles, R is the gas constant, T is temperature in K

(2.85 atm)(12.5 L) = (n)(.08206)(27 C + 273)

n = 1.45 moles x 35.45 grams / mol Cl2 = 51.3 grams

Consider the reaction

Rama09 [41]

Answer:

D. 5.0

Explanation:

Step 1: Write the balanced equation at equilibrium

2 NO₂(g) ⇄ N₂O₄(g)

Step 2: Calculate the concentration equilibrium constant

The concentration equilibrium constant (Kc) is equal to the product of the concentrations of the products raised to their stoichiometric coefficients divided by the product of the concentrations of the reactants raised to their stoichiometric coefficients.

Kc = [N₂O₄]/[NO₂]² = 0.2 / 0.2² = 5

Ugo [173]

Answer : The total volume of gas produced are, 11.5 L

Explanation :

First we have to calculate the moles of ammonium carbonate.

$\text{Moles of }(NH_4)_2CO_3=\frac{\text{Mass of }(NH_4)_2CO_3}{\text{Molar mass of }(NH_4)_2CO_3}$
