Answer:

1 mol Be

Explanation:

First look at periodic table. Be (Beryllium) has an atomic mass of 9.012

1 mole of Be atoms = 9.012 g Be (this is your conversion factor)

Start with what you are given: 9.01 b Be. Then look at the periodic table. Be has an atomic weight of 9.012g. In order to cancel out the g place how you see here, cross out the g and your are left with mole Be on top. divide 9.01 by 9.012 to get .99977807. round that to 1 mol Be

[tex](\frac{9.01 g Be}{1} )(\frac{1moleBe}{9.012 gBe} )=.99977807 moleBe[/tex]

Explanation:

However, Will should win the match if other conditions are the same between the two of them. This is because Will is pushing with a higher force (of 62 Newtons). This is because the higher the force, the higher the workdone. The formula associated to the workdone here is

Workdone = Force × distance

Answer:

they are located on the abbism

The time taken is 2x the depth of the sea

Linear motion consists of 2: constant velocity motion with constant velocity and uniformly accelerated motion with constant acceleration  

An equation of constant velocity motion  

[tex]\large {\boxed {\bold {x = v \times \: t}}}[/tex]

x = distance = m  

v = speed = m / s  

t = time = seconds  

The principle used in measuring depth is to use the reflection of sound waves emitted by the instrument towards the bottom of the sea. The sound will be reflected and received back by the instrument. So that the time taken is 2x the depth of the sea (emitted time + reflected time), so that the calculation of the depth distance must be divided by 2

Answer:

CO2+H20 for the first question, AlCl3 + Ag for the second or C and B

c) CO₂ + H₂O

C₃H₈+O₂→ CO₂ + H₂O

Explanation:

Firstly we need to know about combustion, it is a chemical process which involves the reaction of a substance with oxygen.

The chemical reaction given below represents the combustion of propane which yields to the production of carbon dioxide and water molecule.

C₃H₈+O₂→ CO₂ + H₂O

The balanced chemical reaction is represented below:

C₃H₈ +5O₂ → 3CO₂ + 4H₂O

Answer:

water and oxygen

Explanation:

only iron and iron alloys can rust whereas other elements corrode. for rusting to happen, 2 substances need to be present: water and oxygen

Answer:

Metal[Iron]+Water+air[Oxygen]-->Rusting

Explanation:

Rusting is an oxidation reaction.The iron reacts with oxygen and water to form hydrated iron[III]oxide.which is seen as rust due to the change in color [to brown]

Answer: Molality of a saline solution = 1.14 moles per kg

Explanation:

Given mass of NaCl (m)= 50.0 g

Mass of solvent = 0.750 kg

Molar mass of NaCl (M)= 23 g + 35.5 g = 58.5g  [Atomic mass of Na = 23 u , atomic mass of Cl = 35.5 u]

Number of moles (n) =[tex]\dfrac{m}{M}[/tex]

[tex]\dfrac{50}{58.5}=.8547[/tex]

Molality = [tex]\dfrac{\text{Number of moles }}{\text{Mass of solvent in kg}}[/tex]

[tex]=\dfrac{0.8547}{0.750}=1.1396\approx1.14\text{ moles per kg][/tex]

Hence, molality of a saline solution = 1.14 moles per kg

Explanation:

Energy, which cannot be created nor destroyed according to the law of conservation of energy, exists in different forms. These forms of energy are, however, interconvertible. According to this question, Henry is in the community investigating sources of chemical energy for his science experiment.

Chemical energy is one of the forms of energy produced or used up during chemical reactions. Based on the options provided, the best examples of chemical energy Henry can use is "A squirrel eating acorns and a fire burning".

- A squirrel eating acorns is a source of chemical energy Henry can use because chemical energy are stored in the bonds of the food molecule (acorns).

- A fire burning is another source of chemical energy because burning is a chemical process.

Answer: A

Explanation: Hydrogen bonds compare with other intermolecular forces because of that fact that they are stronger than other Van Der Waals forces. So, the answer to the question should be A.

Answer:D

Explanation: if you have more than 2 authors , you cite the article by using the last name of the author followed by the phrase “et al”

APA- style citation is a writing format to mention and cite the sources in the journals and papers. Citation for an article with 3 authors is given as, Jones, et al., 2012. Thus, option D is correct.

APA- style citation is the format given by the American Psychological Association. It is a citation style that quotes the author's last name and date. The data quoted are enclosed in parentheses. For example, (Robert, 1997)

Unlike MLA, the APA citation style capitalizes only the titles and proper nouns. The tiles in the source are written in italics. The in-text and the reference list of the citation differ a little.

When a source contains three authors then, the APA citation style writes the last name of the author followed by the et al., and the year like Jones, et al., 2012.

Therefore, option D. Jones, et al., 2012 is the correct APA citation style.

Answer:

The kinetic molecular theory can be used. Temperature is increased, so the average kinetic energy and the rms speed should also increase. This means that the gas molecules will hit the container walls more frequently and with greater force because they are all moving faster.

Answer:

B

Explanation:

literal means actual

The language used in a manner that implies another, less literal meaning is figurative language. Option B is correct.

Figurative language is a type of language which is written in words and paragraphs which are meaningful and readable but not true or right or litrally true just use for giving examples.

Some examples are love is a battlefield or I am going through a rollercoaster of emotions etc. basically comparison of real-life situations to fictional thoughts or not literally true.

Therefore, option B is correct. The language used in a manner that implies another, less literal meaning is figurative language.

Explanation:

A NON-polar, totally symmetrical molecule like C2Cl4, known as tetrachloroethene, is used for DRY CLEANING clothes because it attracts to the non-polar grease stains that are NOT effectively removed by polar water molecules. The dry cleaning process is NOT dry at all (C2Cl4 is a liquid).

According to the molecular geometry,as C₂Cl₄ molecule is symmetrical it is non-polar.

Molecular geometry can be defined as a three -dimensional arrangement of atoms which constitute the molecule.It includes parameters like bond length,bond angle and torsional angles.

It influences many properties of molecules like reactivity,polarity color,magnetism .The molecular geometry can be determined by various spectroscopic methods and diffraction methods , some of which are infrared,microwave and Raman spectroscopy.

They provide information about geometry by taking into considerations the vibrational and rotational absorbance of a substance.Neutron and electron diffraction techniques provide information about the distance between nuclei and electron density.
