Answer:

Between carbon and silicon, silicon element has the strongest attraction between its nucleus and its valence electrons.

because silicon's nucleus is bigger than carbon.silicon loses electrons easily than carbon.

A scientist places a large beaker containing 325 g of 50degree Celsius water into a microwave. He has to run the microwave for 3
Bingel [31]

The amount of energy absorbed by the 325g of water is 57,057J. Details about calorimetry can be found below.

<h3>How to calculate energy?</h3>

The energy absorbed by a mass of substance can be calculated using the following formula;

Q = mc∆T

Where;

  • Q = quantity of heat absorbed
  • m = mass of substance
  • c = specific heat capacity
  • ∆T = change in temperature

Q = 325g × 4.18 × (92 - 50)

Q = 57,057J

Therefore, the amount of energy absorbed by the 325g of water is 57,057J.

How many questions would you need to separate ten arthropods into different branches
Vikki [24]

Answer:

10.

Explanation:

We need 10 question to separate ten arthropods into different branches because each arthropod belongs to separate branch and each branch needs explanation. Phylum Arthropoda is considered as the largest phylum in the animal world, and insects form the largest class within this phylum due to its highest number of individual or organisms. Each arthropods are different from one another so they needs more questions to separate them from each other.

Cuál es la importancia de una fórmula química y explique las clases de fórmulas con sus ejemplos respectivos.
Ksenya-84 [330]

Answer and Explanation:

Las fórmulas químicas sirven para conocer qué elementos químicos y en qué cantidad están presentes en un compuesto químico. Por ejemplo: la fórmula química del dióxido de carbono es CO₂. Esta fórmula nos indica que la molécula de dióxido de carbono está formada por 1 átomo del elemento químico carbono y 2 átomos del elemento oxígeno.

Los diferentes tipos de fórmulas químicas son: fórmula empírica, fórmula molecular, fórmula semi-desarrollada y fórmula desarrollada. Tomando como ejemplo al compuesto <em>butano</em>:

- Fórmula empírica: C₂H₅ (indica que hay 2 átomos de C por cada 5 átomos de H; es una fórmula mínima)

- Fórmula molecular: C₄H₁₀ (indica que en realidad cada molécula de butano tiene 4 átomos de C y 10 átomos de H).

- Fórmula semi-desarrollada: CH₃CH₂CH₂CH₃ (indica el órden en que se unen los átomos en la molécula).

-Fórmula desarrollada: ver dibujo adjunto (indica cómo están unidos los átomos dentro de la molécula. Ahora vemos los enlaces entre los átomos y que los 2 átomos de C de los extremos están unidos a 3 átomos de H y a otro C, y los dos átomos de C del medio están unidos cada uno a 2 C y 2 H).
