La plata forma 2 isotopos cuyas masas atomicas son del 106.90 y 108.90 uma. El primer isotopo 51.82% y el segundo 48.18% cual es la masa atomica

Answers

Answer 1

Answer:

107.86

Explanation:

La masa atómica de un elemento es la suma del producto de la masa isotópica relativa y la abundancia de cada isótopo.

Eso es:

masa atómica = suma (masa isotópica * abundancia)

Dado que un isótopo con una masa de 106.9 tiene una abundancia del 51.82% (0.5182) mientras que el otro isótopo con una masa de 108.9 tiene una abundancia del 48.18% (0.4818). Por lo tanto:

Masa atómica = (106.9 * 0.5182) + (108.9 * 0.4818) = 107.86

what is the direct and indirect pronouns and when we use it (en español)​

Answers

The Direct Object, also called Direct Complement, is the part of the sentence that receives the action of the verb.

Its function is to replace a person, animal or thing in conversation as well as in writing to avoid repetition; when they have already been seen in a sentence or external context where the statement occurs.

The Direct Object can answer the questions what? or who?; with respect to the verb.

Examples:
• Ayer vi una obra de teatro. (Yesterday I saw a play)
Ayer la vi. (yesterday I saw)

• Conozco a tu hermano. (I know your brother)
Lo conozco. (I know him)

Brother is masculine, therefore, it is the pronoun LO.

Answer:

Spanish:

Los pronombres de objeto indirecto en español se utilizan para reemplazar una palabra o frase, que en la oración, cumple esa función. Por lo general, se colocan antes del verbo, cuando este está conjugado. Si el verbo no está conjugado, entonces el pronombre de objeto indirecto se coloca después del verbo.

English:

The Spanish indirect object pronouns are used to replace a word or phrase, which in the sentence, fulfills that function. They are usually placed before the verb, when this is conjugated. If the verb is not conjugated, then the indirect object pronoun is placed after the verb

What is meant by migration? list out any three factors which affect migration and mention any four effects created by it​

Answers

Answer:

Below

Explanation:

depends on what you are talking about but Migration can mean "movement from one part of something to another" or "seasonal movement of animals from one region to another"

Migration of skilled workers leads to a greater economic growth of the region. Children get better opportunities for higher education. The population density is reduced and the birth rate decreases.

Migration also delivers major economic benefits to home countries. While migrants spend most of their wages in their host countries – boosting demand there – they also tend to send money to support families back home. Such remittances have been known to exceed official development assistance.
