The atmospheric pressure on mars is around 7 millibar, where the gravitational constant
is 3.7 m/s² instead of Earth's 9.8 m/s². What height of water column would be stable on
Mars? Assume a density of water of 1.0g/mL.
The height of water column would be stable on Mars is 1.89 m
To answer the question, we need to know what the pressure on mars is
What is the pressure on mars?The pressure on mars P = ρgh where
ρ = density of water = 1.0 g/mL = 1.0 × 10⁻³ kg/1 × 10⁻³ L = 1 kg/L = 1 kg/1 × 10⁻³ m³ = 1000 kg/m³, g = acceleration due to gravity on mars = 3.7 m/s² and h = height of water column.Height of water columnMaking h subject of the formula, we have
h = P/ρg
Since
P = 7 mbar = 7 × 10⁻³ bar = 7 × 10⁻³ × 10⁵ Pa = 700 Pa,ρ = 1000 kg/m³ and g = 3.7 m/s²Substituting the values of the variables into the equation, we have
h = P/ρg
h = 700 Pa/(1000 kg/m³ × 3.7 m/s²)
h = 700 Pa/370 kg/m²s²
h = 1.89 m
So, the height of water column would be stable on Mars is 1.89 m

Guanine pairs with cytosine using ______ noncovalent hydrogen bonds, while adenine pairs with thymidine using ______ noncovalent hydrogen bonds. Multiple choice question. two; two
Guanine pairs with cytosine using three noncovalent hydrogen bonds, while adenine pairs with thymidine using two noncovalent hydrogen bonds.
Why does cytosine and guanine have 3 hydrogen bonds?Cytosine and guanine are joined by three hydrogen bonds. The Watson and Crick bases differ from one another in strength as a result. Thymine and adenine bonded base pairs in DNA are weaker than guanine and cytosine bonded base pairs. Size and structure of the specific nucleotides cause Adenine and Thymine to always pair together while Cytosine and Guanine always pair together.
Adenine and thymine can make two hydrogen bonds, while cytosine and guanine can form three hydrogen bonds. Or, to put it more simply, A and G form bonds. Because each base can only link with one other base, the process is known as complementary base pairing.

After spraying water on a waxed surface, a student notices that the water beads up to form many individual drops rather than being spread out evenly across the surface. what property of water causes it to bead up like this?
Property of water:
Due to the water's ability to stick together (Cohesion), droplets form instead of being spread evenly.
The strong cohesion between water molecules:
Cohesion is defined as the firm attraction between molecules of the same type.This characteristic of water is due to hydrogen. Water molecules are maintained intact by the strong connections that hydrogen forms with one another. Since hydrogen bonds are more attracted to one another than to the wax surface, they tend to bead when sprayed on it.Additionally, the surface tension of water is very strong. This indicates that the molecules on the water's surface are not being drawn in by other molecules in the water's interior due to comparable molecules surrounding them on all sides. These molecules tightly attach to one another while only slightly adhering to the other medium. These water drops are rounded due to surface tension, which allows them to cover the least amount of surface area.Learn more about cohesion here:

What conclusion can you make about the atomic number and the number of neutrons for the first 20 elements of the Periodic Table?
Answer: It has more neutrons. Its mass number is larger than the atomic mass number for carbon.
Explanation:
We can see that all the isotopes of Carbon occupies the same slot in the periodic table and thus the same periodic number.
Atomic number of carbon = 6
Periodic Table gives us the information of Atomic number and mass number of atoms of an element.
Atomic number does not give any information about the number of neutrons of an atom. Atomic number of an element is the number of protons in the nucleus of each atom of that element.
Mass number is defined as the total number of protons and neutrons in an atom. Mass number of a typical carbon atom is equal to 12.
Isotopes are variants of a particular chemical element which differ in number of neutrons. Hence, the mass number of different isotopes of the same element varies and gives us information about the number of neutrons present in that atom at the same time.
The mass number of Carbon-14 is equal to 14.
Atomic number of C-14 = Protons in Carbon-14 = 6
Neutrons in Carbon-14 = Mass Number - Atomic Number
Neutrons in C-14 = 14-6

A gas is contained in a thick-walled
balloon. When the pressure
changes from 1.21 atm to 2.52 atm,

1.72 L and the temperature changes
from 293 K to____________ K.
Which variable is held constant?
A.P B.V C.n D.T
Thank you! :)
Answer:
C.) n
Explanation:
-----> P = pressure (atm)
-----> V = volume (L)
-----> T = temperature (K)
-----> n = number of moles
According to the problem, it seems like pressure (P), volume (V), and temperature (T) are all changing. The problem never brings up whether the number of moles (n) has changed. Therefore, the number of moles (n) must have been held constant.
________________________________________________________
If you need to know what the temperature changes to....
When the number of moles is held constant, you can find the change in the other variables using the Combined Gas Law equation:
P₁V₁ / T₁ = P₂V₂ / T₂
In this formula, "P₁", "V₁", and "T₁" represent the initial pressure, volume, and temperature. "P₂", "V₂", and "T₂" represent the final pressure, volume, and temperature. You can find the final temperature by plugging in the given values and simplifying.
P₁ = 1.21 atm P₂ = 2.52 atm
V₁ = 3.75 L V₂ = 1.72 L
T₁ = 293 K T₂ = ? K
P₁V₁ / T₁ = P₂V₂ / T₂ <----- Equation
(1.21 atm)(3.75 L) / (293 K) = (2.52 atm)(1.72 L) / T₂ <----- Insert values
0.015486 = (2.52 atm)(1.72 L) / T₂ <----- Simplify left side
0.015486 = 4.3344 / T₂ <----- Multiply 2.52 and 1.72
0.015486 x T₂ = 4.3344 <----- Multiply both sides by T₂

the role of the microscope world in creating new material.
Explanation:
Trust me ;)
There are two stable isotopes of carbon, carbon -
12
and carbon -
13
. Carbon -
12
has a mass of exactly
12
amu, and carbon -
13
has a mass of
13.003
amu. The average atomic mass of carbon
is
12.011 amu. What does this tell you about the
relative abundances of the two isotopes?
a. Carbon -
12
is more abundant than carbon
13
because the average atomic mass is closer
to the mass of carbon
12
b. There is not enough information to
determine anything about the relative
abundances of the two isotopes.
c. Carbon
13
is more abundant than carbon
12
because the average atomic mass is closer
to the mass of carbon
13
d. Carbon
12
and carbon -
13
are equally abundant
There is not enough information to determine anything about the relative abundances of the two isotopes.
What are isotopes?Isotopes are atoms that have the same atomic number but different mass numbers. We know that all the isotopes of an element are not available to the same extent in nature.
Hence, from the average atomic mass of carbon, we can see that there is not enough information to determine anything about the relative abundances of the two isotopes.
