What is a solution for deforestation (full sentences please)

Chemistry
2 answers:
iVinArrow [24]2 years ago
5 0

The best solution to deforestation is to curb the felling of trees by enforcing a series of rules and laws to govern it. Deforestation in the current scenario may have reduced; however, it would be too early to assume. The money-churner nature of forest resources can be tempting enough for deforestation to continue.

Some chemists believe that satisfaction of the octet rule should be the top criterion for choosing the dominant lewis structure
Fudgin [204]

Lewis structures refers to the diagrams used to signify the bonding between the atoms of a molecule and the lone pair of electrons, which may prevail in the molecule. These structures are drawn on the basis of the formal charge of each atom within the ion or molecule.

The formal charge refers to the charge assigned to an atom in a molecule, which all the electrons are shared equivalently amongst the atoms regardless of its electronegativity.

The rule for formal charge calculation is,

Formal charge = no of valency shell electron - 1/2 of the no of shared pair electron - no of lone pair electron.

So, in this case, the formal charge of P = 5 - 1/2 (10) - 0 = 0

The valence shell of P have 5 electrons. The total 5 bond is there in the given composition, so total 10 bonding electron, and there is no lone pair of electron on P atom. So, formal charge of P is 0.

A sample of sodium reacts completely with 0.284 kg of chlorine, forming 468 g of sodium chloride. What mass of sodium reacted?
Verizon [17]

Answer:

mass of sodium reacted is 184.1 g

Explanation:

  • Na + Cl → NaCl

mass Na = X = ?

∴ mass NaCl = 468 g

∴ mass Cl = 0.248 g

∴ molar mass NaCl = 58.44 g/mol

∴ atomic mass Cl = 35.453 a.m.u

∴ atomic mass Na = 22.989 a.m.u

⇒ moles Na = (X gNa)*(mol Na/22.989 g) = X/22.989 mol Na

⇒ mass NaCl = (X/22.989 mol Na)*(mol NaCl/mol Na)*(58.44 gNaCl/mol NaCl) = 468 g NaCl

clearing "X":

⇒ ((58.44)(X))/(22.989) = 468 g

⇒ X = 184.1 g = mass Na reacted

In this compound nitrogen = 36.86 / 14.0067 = 2.63 
<span>And oxygen = 63.14 / 15.9994 = 3.95 <span>
now we have: N----- 2.63 and O----3.95

4. A sample of gas has a pressure of 700 mmHg and 30.0°C. Ar what temperature would the pressure be 600 mmHg if the volume remai
shtirl [24]

Answer:

T₂  = 259.84 K

T₂  = -13.31 °C

Explanation:

Given data:

Initial pressure = 700 mmHg

Initial temperature = 30.0°C (30+273.15 K = 303.15 K)

Final temperature = ?

Final pressure = 600 mmHg

Solution:

According to Gay-Lussac Law,

The pressure of given amount of a gas is directly proportional to its temperature at constant volume and number of moles.

Mathematical relationship:

P₁/T₁ = P₂/T₂

Now we will put the values in formula:

700 mmHg /303.15 K  = 600 mmHg / T₂

T₂  = 600 mmHg × 303.15 K / 700 mmHg

T₂  =181890 mmHg.K /700 mmHg

T₂  = 259.84 K

Temperature in celsius

259.84 K - 273.15 = -13.31 °C

PLEASE HELP THIS IS DUE IN AN HOUR!!!
Soloha48 [4]

Explanation:

The hydronium ion concentration can be found from the pH by the reverse of the mathematical operation employed to find the pH. [H3O+] = 10-pH or [H3O+] = antilog (- pH) Example: What is the hydronium ion concentration in a solution that has a pH of 8.34? On a calculator, calculate 10-8.34, or "inverse" log ( - 8.34).
