Water can undergo a change of state when its energy changes at specific temperatures. Solid water, or ice, changes into liquid water when its energy increases at its melting point. a. Describe this process. b. Explain how the energy changes with each state.

Answers

Answer 1

Answer: The solid turns into liquid during melting.

Explanation:

a. The process of a solid turning into liquid is called melting. The solid ice turns into a liquid during the melting process. The solid molecules gain energy and flow as a liquid.

b. The energy of the molecules increases in the liquid state. When the ice turns into a liquid the energy of the molecules increases. The application of heat or excess temperature increases the energy of the molecules.

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).

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.

Question 3 (1 point)
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.

Which of these statements about density is NOT true? a The density of a block of substance A equals 10.0 g/cm3. 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."

The five d orbitals can hold up to 10 electrons. Thus, the third level holds a maximum of 18 electrons: 2 in the s orbital, 6 in the three p orbitals, and 10 in the five d orbitals.

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.

.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.

A 5.0 milliliter sample of a substance has a mass of 12.5 grams. What is the mass of a 100 milliliter sample of the same substance?

Answers

Answer:

It sould be 250 grams

Explanation:

It is given that, 5 millimeter sample has the mass of 12.5 grams. Then, 100 millimeter sample have a mass of  250 g.

What is mass ?

Mass of a substance is a physical quantity that describes the total amount of the substance. Mass is an extensive property since it depends on the change in amount or quantity of the substance.

The SI unit of mass is grams (g). Other units are kilograms, milligrams , pounds etc. Mass is of small substance is expressed in grams and that bigger things are usually expressed in kilograms.

Given that mass of 5 ml sample = 12.5 grams

then mass of 1 ml = 12.5/5 = 2.5 g

then mass of 100 ml = 2.5 × 100 = 250 grams.

Therefore, the mass of 100 ml of the sample is 250 g.

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)

It is incorrect because it should have a total of eight electrons with two electrons between each H and O

Further explanation

Lewis structure shows the form of bonds that occur in the valence electrons of an element or compound

This bonding usually occurs in covalent bonds

Valence electrons are electrons used in a chemical bond

The main group elements usually have valence electron configurations in the ns and np subshells, While the transition elements in the subshells (n-1) d and ns.

Element O has 6 valence electrons

Element H has 1 valence electron

To achieve stability, the element O needs 2 more electrons which are obtained from 2 electrons from the H element, while the H element needs 1 electron to be stable

So that a covalent bond is formed
