Which of the following elements is the most electronegative: arsenic, phosphorus,
sulfur, or selenium?
selenium
arsenic
phosphorus
sulfur

Answers

Answer:

sulfur

Explanation:

From the given lists of elements, the one with the most electronegativity is Sulfur.

  Electronegativity is of an element is a property that combines the ability of its atom to lose and gain electrons.

It is a measure of the relative tendency with which the atoms of the element attract valence electrons in a chemical bond.

 

Using the Pauling's electronegative table of elements;

   Here are electronegativity values of the given elements;

selenium                 2.4

arsenic                    2.0

phosphorus            2.1

sulfur                      2.5

We see that the value of sulfur is the highest.

The most common physical state of the elements is

Answers

Answer: Solids, gases, or liquids

Explanation:

Matter can undergo physical and chemical changes called Phase Changes. Substances are classified based on physical states, often referred to as the States of Matter. At room temperature and pressure the common Physical States of elements are solids, gases or liquids.

Most are solids only 11 are gases and 2 are liquids

The most common physical state of elements in the periodic table is Solids as there are about 84 elements which exists as solids at room temperature and pressure in the periodic table

Elements in the periodic table can exist as one of the prominent physical states at room temperature and pressure.

These physical state may be;

SolidLiquidor Gas

Elements which are solid at Room Temperature are about 84.

At room temperature and pressure, only two elements are existent in liquid phase are: Bromine. Mercury.

A look at the periodic table evidently tells that there are 11 elements in the table that exist in the gaseous state at room temperature and pressure.

These elements are Hydrogen, Helium, Nitrogen, Oxygen, and the other Noble gases.

What is the Independent and Dependent Variables for this experiment?
"How does the amount of salt in water affect how an egg floats?"
please help!!

Answers

Answer:

The egg is the dependent variable and the salt is the independent variable.

Explanation:

The dependent variable is something that stays the same throughout the experiment. The independent variable is something that might not stay the same throughout the experiment. The egg does not change because we're using an egg and not an egg and then a tomato or a potato, but the salt does change because we're changing the amount of salt in the bowl/plate or anything else that we are using to perform this.

This is kinda long but it explains mostly everything. DM me for more dependent and independent variable help.

Distinguish between organic acid and mineral acid​

Answers

Answer:

Mineral acids are very important to chemical procedures. An organic acid is an organic compound with acidic properties. ... Generally, organic acids are weak acids and do not dissociate completely in water, whereas the strong mineral acids do.

Answer:

Organic Acids:

organic acids are weaker.organic acids always contain carbon, hydrogen and oxygen. organic acids are naturally occurring. organic acids are found in plants and animals.Examples: Methanoic acid, ethanoic acid, lactic acid etc.

Mineral Acids:

Mineral acids are strong. Mineral acids are derived from one or more minerals found on Earth.Other than hydrogen, no other element is fixed in mineral acids.Example: Hydrochloric acid, sulphuric acid

.Over a period of 1,000 years, a lake becomes a maple forest. Is this process primary or secondary succession? Explain your answer.

Answers

Answer:

It is secondary succession.

Explanation:

primary succession only occurs in areas where there was no previous ecosystem

In the production of maple forest over the 1,000 years period, there has been the presence of the lake. Thus the production in the lake has been the secondary succession.

The primary and secondary succession has been the development process in the ecosystem. The ecosystem development can be taken place when there has been no previous vegetation, or when there has been the available ecosystem.

The primary succession can result when there has been no available previous ecosystem. The secondary succession can take place when there has been a previously existing ecosystem.

In the production of maple forest over the 1,000 years period, there has been the presence of the lake. Thus the production in the lake has been the secondary succession.

If I cut the block in half, its density will equal 10.0 g/cm3. b A cubic meter of bricks is more dense than a cubic meter of feathers. c It is possible to identify a substance by its density. d The density of a substance is always the same, regardless of temperature.

Answers

Answer:

d. The density of a substance is always the same, regardless of temperature.

Explanation:

Density is a characteristic property of water and defined as the mass per unit volume.

The density of a substance always remains the same at the same temperature regardless of the size of the sample. The density of the sample changes with temperature and pressure. for example : The density of a substance increases with a decrease in temperature as the volume increases.

Hence, the statement about density is not true is " d. The density of a substance is always the same, regardless of temperature."

What do Lucille's cells need in order for her body to function properly? How might a problem with Lucille's respiratory system lead to low levels of oxygen in her cells? Why does having low levels of oxygen in her cells make it difficult for Lucille to play soccer?

Answers

Answer:

In order for her body to act correctly, Lucille's cells require glucose and oxygen. A problem with Lucille's respiratory system leading to low levels of oxygen in her cells is known as Hypoxemia. Having low levels of oxygen in her cells will make it difficult for Lucille to play soccer because she would not be able to breathe .If her respiratory system doesn't function properly, so enough oxygen molecules will not move into her respiratory system , ensuring that her cells won't have enough oxygen molecules. Playing soccer is difficult if you don't have enough air.

Explanation:

ABOUT HYPOXEMIA -: It is called hypoxemia to have low oxygen levels in your blood. It is called hypoxia to have insufficient oxygen levels in the tissues. Hypoxemia at high altitudes can occur. Hypoxemia that induces low levels of oxygen in the tissues of the body is called hypoxia. The two words are often used by people interchangeably, but they are not the same thing.

The capacity of the body to supply normal amounts of oxygen to the blood can interfere with a number of conditions and circumstances. Some of hypoxemia's most prevalent causes include:

Heart problems, heart defects included  .Lung disorders such as asthma , bronchitis, emphysema. High-altitude areas where oxygen is lower in the air.  Powerful drugs for pain or other conditions that delay respiration . Sleep apnea (breathing impairment during sleep)  .Lung tissue inflammation or scarring (as in pulmonary fibrosis).

Answer:

V = 21.2 cm³

Explanation:

Given data:

Diameter of block = 3.0 cm

Volume of block = ?

Solution:

Formula:

V = 2πr³

First of all we will calculate the radius from diameter.

r = d/2

r = 3.0 cm/2

r = 1.5cm

V = 2(22/7) (1.5cm)³

V = 2(3.14) (3.375cm³)

V = 21.2 cm³
