<span>In chemistry, the law of definite proportions, sometimes called Proust's law or the law of definite composition, or law of constant composition states that a given chemical compound always contains its component elements in fixed ratio and does not depend on its source and method of preparation. An equivalent statement is the law of constant composition, which states that all samples of a given chemical compound have the same elemental composition by mass.</span>
Answer:
A polar bond is one where the charge distribution between the two atoms in the bond is unequal. A polar molecule is one where the charge distribution around the molecule is not symmetric. It results from having polar bonds and also a molecular structure where the bond polarities do not cancel.

Just a thing I need my brainliest!!
Explanation:
Also refered to as consumers, heterotrophs areorganisms that obtain their energy (nutrition) from organic compounds/materials.In other words, they are organisms that are unable to produce their ownfood (unlike autotrophs) and therefore have to consume/ingest organic compoundsas a source of energy. Compared to autotrophs (which occupy the base of thefood-web triangle), heterotrophs occupy the upper levels of the food web giventhat their survival is dependent on the producers
Answer:
ΔHreaction = 263.15 kJ/mol
Explanation:
The reaction is as follow:
OH + CF₂Cl₂ → HOF + CFCl₂
You need to calculate the enthalpy of reaction and for this it is necessary to know the standard enthalpies for each of the compounds. These enthalpies are as follows and can be found in your textbook or on the Internet.
ΔHreaction = ∑ΔHproducts - ∑ΔHreactants
Answer:
<em>The N given in the question is normality while the M given in the question designates morality.
</em>
Explanation:
There are minor differences between both the terms normality and morality given in the question and both are inter convertible.
When one litre of solution is considered when the particles of solute in that litre would show the morality of the solution while when one litre of Solution is considered and equivalent are given then it is known as normality.
