guajiro [1.7K]

Answer : The correct answer is a) an exothermic reaction that releases energy.

Combustion reaction is generally referred as burning or when hydrocarbon reaction with oxygen to produce carbon dioxide and water . Combustion reaction releases energy. Example :

CH₄ + O₂ → CO₂ + H₂O + Energy or heat .

The reaction which releases energy or heat are known as Exothermic reactions .

Since it says hot dogs and hamburgers are cooked means they are undergoing combustion chemical reaction and so they are exothermic reactions. So option a) an exothermic reaction which releases energy is correct .

La lección difícil, cuadro de William-Adolphe Bouguereau.

El aprendizaje es el proceso a través del cual se modifican y adquieren habilidades, destrezas, conocimientos, conductas y valores.1​ Esto como resultado del estudio, la experiencia, la instrucción, el razonamiento y la observación. Este proceso puede ser analizado desde distintas perspectivas, por lo que existen distintas teorías del aprendizaje. Es una de las funciones mentales más importantes en humanos, animales y sistemas artificiales. En él intervienen diversos factores que van desde el medio en el cual se desenvuelve el ser humano, así como los valores y principios que se aprenden en la familia. En esta última se establecen los principios del aprendizaje de todo individuo y se afianza el conocimiento recibido, el cual forma la base para aprendizajes posteriores.

El aprendizaje humano está relacionado con la educación y el desarrollo personal. Debe estar orientado adecuadamente y es óptimo cuando el individuo está motivado. El estudio sobre cómo aprender interesa a las Ciencias de la Educación, la pedagogía, la neuropsicología, la psicología educacional y la antropología, aquella que recoge las peculiaridades propias de cada etapa del desarrollo humano. Concibe sus planteamientos teóricos, metodológicos y didácticos para cada una de ellas. Dentro de ella se enmarcan, por ejemplo la pedagogía y la andragogía, la educación de niños y adultos respectivamente.2​

How many grams of O2(g) are needed to completely burn 46.0 g C3H8(g)?
Veronika [31]

Answer:

167,3 grams of O2 (g)

Explanation:

According to the following balanced equation:

C3H8 + 5 02 ---> 3 CO2 + 4 H20

We calculate the mass of the moles:

5 mol O2 = 16grams/mol x2x 5= 160 grams/mol

1 mol C3H8= 3 x12 grams/mol + 8 x 1 gram/mol= 44 grams/mol

If 44 grams C3H8 react with--------- 160 grams O2

46 gramsC3H8 react with    --------X = (46x160)/44 =167, 3 grams O2

What types of elements are shown in the polyatomic ions in model 1?
boyakko [2]
These ions are disjoint by the charge on the ion into four dissimilar tables and listed alphabetically within each table. Each polyatomic ion, has it called, chemical, formula, two dimensional drawing, and three dimensional representation are given.
The three dimensional buildings are drawn as CPK models. CPK structures represent the atoms as sphere, where the radius of the sphere is equal to the van der waals radius of the atom; these buildings give a measure up the volume of the polyatomic atom.
