Answer:non-polar covalent compounds

Explanation:

In chemistry, like compounds interact. If a solvent is covalent and nonpolar, it will also dissolve nonpolar covalent compounds. This is because, they contain similar patterns of intermolecular interaction. Hence compounds that posses the same kind of intermolecular interaction can form a solution.

How many grams of Chromium(III) nitrate are produced when Chromium reacts with 0.85 moles of Lead(IV) nitrate to produce chromiu
mina [271]

Grams of Chromium(III) nitrate produced : 268.95 g

<h3>Further explanation</h3>

Given

0.85 moles of Lead(IV) nitrate

Required

grams of Chromium(III) nitrate

Solution

Reaction

Balanced equation :

<em>2Cr₂ + 3Pb(NO₃)₄ ⇒ 4Cr(NO₃)₃ + 3Pb </em>

From the equation, mol ratio of Pb(NO₃)₄  : Cr(NO₃)₃ = 3 : 4, so mol Cr(NO₃)₃

mol Cr(NO₃)₃ =

\tt \dfrac{4}{3}\times 0.85=1.13

Mass of Chromium(III) nitrate (MW=238.0108 g/mol) :

mass = mol x MW

mass = 1.13 x 238.0108

mass = 268.95 g

Compare how fast the rate of CO2 increase is in the last few hundred years with the rate of increase (or decrease, for that matt
Tcecarenko [31]

The rate of CO2 increase is in the last few hundred years is 10 times more with the rate of increase (or decrease, for that matter) in the preceding 400,000 years.

There are many possible reasons for this cause , some primary factors are listed below:

  1. Increase in population
  2. increased emission of green house gases, as we all know auto mobile industry is growing rapidly and this vehicles releases harmful gases like CO2, CO ,etc. and increases carbon % , this CO2 is a main gas component in green house effect.
  3. Deforestation, as the amount of plant decreases the CO2 present in atmosphere increases, plants uses CO2 and sun lite to make their food via photosynthesis.
  4. Increased emission of Industrial flue gases, etc.

How dose a tree turn chemical energy into thermal energy?
Artist 52 [7]

The rays of the sun will go directly to the trees, then trees take up light that absorbs light energy which converting light to chemical potential energy kept in chemical bonds. And when the trees cut into woods and burnt it, it will convert to thermal energy.
