Hi,if its a man by the name of Robert Hooke your looking for information about this is what I found online.Robert Hooke was a English Physicist.He contributed to the discovery of cells while looking at a thin slice of cork. He then thought that cells only exist in plants and fungi.Also in 1665, he published Micrographia.

Hope this is helpful.

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:

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:semiconductor

Explanation:a solid substance that has a conductivity between that of an insulator and that of most metals, either due to the addition of an impurity or because of temperature effects. Devices made of semiconductors, notably silicon, are essential components of most electronic circuits.

Answer:

no

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.

The mass of water is expressed in grams (g) or kilograms (kg), and the volume is measured in liters (L), cubic centimeters (cm3), or milliliters (mL). Density is calculated by the dividing the mass by the volume, so that density is measured as units of mass/volume, often g/mL.

Answer:

True

Explanation:

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.

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.

a. The atomic size of fluorine is very small compared to other halogens. Similarly, fluorine is the highest electronegative atom in periodic table. b.  CIF a T-shaped structure is asymmetric with dipoles that do not cancel out but produce a net dipole.

In a compound with atoms of significant difference in electronegativities, the shared pair of electrons attracts towards the more electronegative atom and this results in a charge separation. The measure of the separation of two electrical charges is called the dipole moment of the compound.

a. Fluorine is the most electronegative atom in periodic table. Compared to other halogens, F has very small atom and have less electron affinity compared to other halogens.

b. Cl - F is an interhalogen compound in which dipole moment  is created by the electronegativity difference between Cl and F. The net dipole moment is towards the F atom.

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
