3.08*10^23 ions of Na+ and Cl- will be present in 30g of NaCl.

Weight of NaCl is equal to sum of weight of one mole of sodium and one mole of chloride.

Mathematically, it can be represented as -

1 mol (Na) + 1 mol (Cl)

= 23.0+ 35.5

= 58.5 g/mol

In 58.5  gram of NaCl, there is one mole of Na or 6.02*10^23 ions

In one gram of NaCl, there will be

  =6.02*10^23/58.5 sodium ions

In 30 grams of  NaCl, the number of sodium ions will be -

(6.02*10^23*30)/ 58.5

=3.08*10^23 ions

kvasek [131]

Answer:

bines relative humidity and temperature in a comfort index

Explanation:

The Heat Index temperature measures how hot it feels when humidity is factored with the air temperature.

It is important for the human body's comfort.

The human body feels warmer in humid conditions it begins to perspire or sweat to cool itself off when the body gets too hot.

The concept of the heat index was developed by George Winterling  in 1978.

The heat index temperature makes assumptions regarding the human body mass and height, clothing, amount of physical activity etc.

The heat index temperature <u>bines relative humidity and temperature in a comfort index.</u>

At 2000 ∘C the equilibrium constant for the reaction 2NO(g)⇌N2(g)+O2(g) is Kc=2.4×103. If the initial concentration of NO is 0.1
Rasek [7]

Answer:

[N_2]=0.0866M

Explanation:

Hello there!

In this case, in agreement to the chemical reaction, it is possible for us to figure out the equilibrium concentration of the N2 product, via an ICE table plugged in the equilibrium expression:

Kc=\frac{[N_2][O_2]}{[NO]^2}\\\\2.4x10^3=\frac{x*x}{(0.175-2x)^2}

In such a way, when solving for x via quadratic equation or just a solver, it is possible to obtain:

x_1=0.0866M\\\\x_2=0.0884M

In such a way, since the root 0.0884 M produce a negative concentration of NO (0.175-2*0.0884=-0.0018M), we infer that the correct root is 0.0866 M; therefore, the concentration of N2 at equilibrium is equal to x:

[N_2]=x=0.0866M

Best regards!

In order to survive, plants absorb sunlight, water, and nutrients from the soil. What property is this?
zvonat [6]

Plants are unique organisms that can absorb nutrients and water through their root system, as well as carbon dioxide from the atmosphere. Soil quality and climate are the major determinants of plant distribution and growth.

kozerog [31]
Answer: Antoine Lavoisier.

He classified the elements into four groups: elastic fluids, nonmetals, metals and earths. Some of the called elementes were not really elements (light and heat). Others were compounds, e.g. hydrochloric acid.
