he descriptions below explain two ways that water is used by plants on a sunny day.

I. In a process called transpiration, some liquid water in leaves changes to water vapor. The water vapor is released into the air through tiny pores in the leaves. This allows more liquid water from the soil to be pulled up the roots and stem to replace water lost from the leaves.

II. Plants use some of this water in leaves in a process called photosynthesis. During photosynthesis, water and carbon dioxide break apart and recombine to form two new substances, oxygen and glucose.

Based on the above description of transpiration and photosynthesis, which type of change happens to water during each process?

In transpiration, because some of its properties change, water undergoes a physical change but keeps its identity. In photosynthesis, because its identity changes, water undergoes a chemical change.

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).

.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.

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.

For the reaction 2NH3(g)↽−−⇀3H2(g)+N2(g) 2 NH 3 ( g ) ↽ − − ⇀ 3 H 2 ( g ) + N 2 ( g ) the equilibrium concentrations were found to be [NH3]=0.250 M, [ NH 3 ] = 0.250 M, [H2]=0.300 M, [ H 2 ] = 0.300 M, and [N2]=0.750 M. [ N 2 ] = 0.750 M. What is the equilibrium constant for this reaction? c= K c =

Answers

Answer:

0.324

Explanation:

The following data were obtained from the question:

Concentration of NH3, [NH3] = 0.25 M

Concentration of H2, [H2] = 0.3 M

Concentration of N2, [N2] = 0.75 M

Equilibrium constant (Kc) =.?

The balanced equation for the reaction is given below:

2NH3 <==> 3H2 + N2

The equilibrium constant, Kc for a given reaction is the ratio of the concentration of the products raised to their coefficient to the concentration of the reactants raised to their coefficient. Thus, the equilibrium constant for the above reaction can be obtained as illustrated below:

Kc = [H2]³ [N2] / [NH3]²

Concentration of NH3, [NH3] = 0.25 M

Concentration of H2, [H2] = 0.3 M

Concentration of N2, [N2] = 0.75 M

Equilibrium constant (Kc) =.?

Kc = [H2]³ [N2] / [NH3]²

Kc = [0.3]³ × [0.75] / [0.25]²

Kc = (0.027 × 0.75) / 0.0625

Kc = 0.02025 / 0.0625

Kc = 0.324

Therefore, the equilibrium constant for the reaction is 0.324

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;

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.

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

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

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)

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."
