Why do group 7 elements have higher melting and boiling points going down?
Genrish500 [490]

Answer:

this is because the van der waals forces or also known as induced dipole-dipole interactions increase because more electrons are present within an atom as you go down

Classify the following substituents according to whether they are electron donors or electron acceptors relative to hydrogen by
igor_vitrenko [27]

Species that have a lone pair of electrons often donate electrons by resonance while substituents that are electron deficient take away electrons by resonance.

<h3>What is resonance?</h3>

The term resonace has to do with the movement of electron pairs in a molecule. Inductive effects has to do with the drawing of electron density towards an atom or bond.

The two effects depends on the nature of a substituent. For instance, species that have a lone pair of electrons often donate electrons by resonance while substituents that are electron deficient take away electrons by resonance.

The question is incomplete hence the exact nature of the substituents can not be determined.

PLEASE HELP!?Consumers must eat other organisms for energy. Which organisms are consumers in this food chain?
Vitek1552 [10]

Answer:

Consumers must consume other organisms to get the food that they need and are known as Heterotrophs as they cannot make their own glucose. These consumers eat producers (plants). Herbivores are considered as first order consumers. These consumers eat consumers and producers (animals and plants).

For the reaction 2 NO(g) + 2 H2(g) =&gt; N2(g) + 2 H2O(g) the following data were collected. What is the rate law for this react
harkovskaia [24]

<u>Answer:</u> The rate law expression for the given reaction is written below.

<u>Explanation:</u>

Rate law is defined as the expression which expresses the rate of the reaction in terms of molar concentration of the reactants with each term raised to the power their stoichiometric coefficient of that reactant in the balanced chemical equation.

For the given chemical equation:

2NO(g)+2H_2(g)\rightarrow N_2(g)+2H_2O(g)

Rate law expression for the reaction:

\text{Rate}=k[NO]^2[H_2]^2

Hence, the rate law expression for the given reaction is written above.
