The forces between water molecules are stronger than the forces between ethanol molecules. Which liquid would probably be most difficult for an insect to walk on?

Answers

Answer 1
An insect would have a harder time walking on ethanol than it would water. Water has stronger intermolecular forces which leads to higher surface tension. The higher surface tension allows for the insect to be easily supported
Answer 2

Answer:
An insect would have an easier time walking on the surface of water than on the surface of ethanol.
Water’s stronger intermolecular forces lead to higher surface tension.
Higher surface tension allows water to support the insect.

Where light is hitting an object

Answers

When lights hits an object, the light either get absorbed, reflected or refracted

The phrase "where light is hitting an object" refers to the specific points or areas on the surface of an object that are directly exposed to light.

These are the regions where photons from a light source directly interact with the object's surface.

When light hits an object, it can be absorbed, reflected, or transmitted depending on the object's properties. The areas where light is hitting will typically appear brighter or illuminated, while the areas in shadow or not directly exposed to light will appear darker.

The distribution of light hitting an object plays a crucial role in determining its visibility, color, and overall appearance.

What is the atomic number of an atom that has 5 neutrons and 4 electrons

Answers

The atomic number is 4.

The atomic number of the given atom is equal to 4.

What is the atomic number?

The atomic number (symbol Z) of a chemical element can be defined as the charge number of an atomic nucleus. For an ordinary atom, the atomic number is equal to the number of protons found in the nucleus of an atom of that element.

The atomic number helps to uniquely identify ordinary chemical elements. In an ordinary uncharged atom or neutral atom, the atomic number of that atom is also equal to the number of electrons.

For a neutral atom, the sum of the atomic number and the neutron number gives the atomic mass. The protons and neutrons have approximately the same mass. Atoms that have the same atomic number but different numbers of neutrons or different mass numbers are known as isotopes.

Given the number of electrons in the atom is 4. Therefore, the atomic number of that atom will be equal to 4.

A given volume of methane diffuses in 20 seconds How long will it take the
same volume of sulphur (IV) oxide to
diffuse under the same condition
(Methane = 16, Sulphur (IV) oxide=64)​

Answers

Explanation:

Relative molecular mass of CH4 = 12 * 1 + 4 = 16

Relative molecular mass of SO2 = 32 + 10 *2 = 64

tSO2/tCH4 = √MSO2/MCH4

t/20 = √64/16 = √4

t/20 = 2

Answers

Answer:

1.375%

Explanation:

Percent Error = measured value - accepted value/ accepted value x 100

Measured Value: 15.78

Accepted Value: 16.00

Work:

[tex]\frac{15.78-16.00}{16.00}[/tex] * 100

[tex]\frac{-.22}{16}[/tex] * 100 = -1.375

You cannot have a negative percentage. Therefore the answer is 1.375%

Briefly summarize how heavy elements are created

Answers

Answer:

Heavy elements are created by fusing two elements together in a lab. They look for “events” that comprise a series of alpha decays that result in spontaneous fission.

Explanation:

Atoms of different element can not have same atomic number because only same type of atoms combine to form element. Atoms belonging to different element can have different atomic number. Therefore, in below given ways we can summarize how heavy elements are created.

What is element?

Element generally consist of atoms or we can atoms combine to form element. Atoms of an element is always same, means all the properties of all atoms of one type of element is same.

Elements heavier than iron cannot be created by fusion because the reaction requires energy to occur. We do, however, perceive elements other than iron all around us. This is accomplished by supernova explosions, which result in neutron capture processes and the production of heavy materials.

Therefore, in above ways we can summarize how heavy elements are created.

Answer:form when magma and lava cool :/

Explanation:hope this helps, and I’m this because ingenious rocks are made/ formed from magma and lava.

The phrase which best describes igneous rocks is option A, .i.e., it forms when lava and magma cool.  

What is igneous rock?

Igneous rocks are formed by the melting of  earth's crust  into magma, . The two types of this rocks are, Extrusive and intrusive igneous rocks . The slow cooling of magma beneath the surface results in intrusive igneous rock.

Magma in the crystal is in molten liquid state which heat by convection and flows out. This creates slight movement in plates and the hot mantle the cools down to form igneous crystals.

Extrusive igneous rock is created when lava above the surface cools quickly. The magma hardens more quickly after being brought to the surface via cracks or volcanic explosions. As a result, these rocks are crystalline, smooth, and fine-grained.

Thus regarding the formation of igneous rocks, option A is correct.

What does the mass of an object depend on?

Answers

Answer:

the mass of an object depends on inertia greater is the inertia greater will be the mass or vice versa

Explanation:

hope it help ^_^

Mass is the most basic property of matter and it is one of the fundamental quantities. Mass is defined as the amount of matter present in a body. The SI unit of mass is the kilogram (kg). The formula of mass can be written as:

Mass = Density × Volume

The mass of a body is constant; it doesn’t change at any time. Only in certain extreme cases when a huge amount of energy is given or taken from a body, the mass may be impacted. For example, in a nuclear reaction, a tiny amount of matter is converted into a huge amount of energy, this reduces the mass of the substance.

There are various units for calculating mass, like, kilograms, grams, lbs, pounds, etc., but the SI unit of mass is "kilograms" or kg. Every unit of mass can be converted to other units by using a proper conversion formula without affecting the meaning and essence of the quantity to be measured.

Scientist at the CDC (Center for Disease Control) in Atlanta, GA are currently developing and testing new treatments and vaccines for the coronavirus. What kind of research are they conducting?

Answers

Answer:

Applied research

Explanation:

The process of developing a new vaccine involves the use of known scientific theories to address specific problems. Here, the outcome of several basic research are put into use to arrive at a targeted outcome. This outcome/product can be continuously modified (if it shows early promise) until the desired effect is achieved and if no "promise" is discovered at critical points of this research, work on this theory (for this research) is suspended another theory is pursued.

This process (described above) in which scientists continuously develop new treatments and/or vaccines and continuously subject it to testing until the desired effect is achieved can be referred to as Applied research.
