Consumers get an idea of the building blocks of foods from ________________ and ________________.
oee [108]

Answer:

Ingredient lists and nutritional facts

Explanation:

The packaged food, a consumer purchases has all its details written on the food package which is also verified by a trusted government institution.

  • <u>Ingredient List </u>

The list tells each ingredient in food product by the food's common or usual name in the descending order by the weight.

  • <u>Nutrition Facts Label </u>

FDA requires this label on most of the packaged foods and the beverages. At top of Nutrition Facts label, there is written total number of the servings in container and serving size of food or drink. Serving size on label is based on amount of the food which people eat typically at one time. Rest of nutrition information on label is based usually on one serving of food or beverage.

Give the number and type of hybrid orbital that forms when each set of atomic orbitals mixes:
evablogger [386]

<u>Two hybrid </u>orbitals of <u>sp </u>type forms when each set of atomic orbitals mixes one p and one s

<h3>What is orbital hybridization?</h3>

In the context of valence bond theory, orbital hybridization (or hybridisation) refers to the idea of combining atomic orbitals to create new hybrid orbitals (with energies, forms, etc., distinct from the component atomic orbitals) suited for the pairing of electrons to form chemical bonds.

For instance, the valence-shell s orbital joins with three valence-shell p orbitals to generate four equivalent sp3 mixes that are arranged in a tetrahedral configuration around the carbon atom to connect to four distinct atoms.

Hybrid orbitals are symmetrically arranged in space and are helpful in the explanation of molecular geometry and atomic bonding characteristics. Usually, atomic orbitals with similar energies are combined to form hybrid orbitals.

When the enthalpy of the reaction is provided, it is always in the context of moles; i.e., ΔHrxn=+252.8 kJ when two moles of CH3
Morgarella [4.7K]

<u>Answer:</u> The balanced chemical equation is written below.

<u>Explanation:</u>

There are 2 types of chemical reaction classified on the basis of heat change:

  • <u>Endothermic reactions </u>: They are the reactions in which energy of products is more than the energy of the reactants. For these reactions, energy is absorbed by the system. The \Delta H comes out to be positive and is written on the reactants side.
  • <u>Exothermic reactions:</u> They are the reactions in which energy of reactants is more than the energy of the products. For these reactions, energy is released by the system. The \Delta H comes out to be negative and is written on the product side.

We are given:

Moles of methanol = 2 moles

Moles of methane = 2 moles

Moles of oxygen gas = 1 mole

\Delta H_{rxn}=+252.8kJ

The chemical equation follows:

2CH_3OH+252.8kJ\rightarrow 2CH_4+O_2

Hence, the balanced chemical equation is written above.
