What traits are found on chromosome 6?More than 120 major human diseases are functionally associated with Chromosome 6, including cancer, heart disease, infectious, immune, and inflammatory disorders, and mental illnesses.
The HLA region, also known as the MHC region in humans, is located on the short arm of chromosome 6 and encodes antigens involved in immunological processes.
The primary function of chromosomes is to transport genetic material from one generation to the next. Chromosomes play an important role in the processes of growth, reproduction, repair, and regeneration, all of which are necessary for survival.
Thus, option D is correct.

What is a word that means carbon and water
Answer:
When Carbohydrates are burned (decomposed ) they break down into carbon and water.
Explanation:
The formula for glucose sugar is C6H12O6 If the compound is broken down it results in
6C+6H2O six carbon atoms and six water molecules.
An experiment that illustrates this well is to pour concentrated sulfuric acid about 1/3 deep into the volume of graduated sucrose sugar in a beaker about 1/4 full
The sulfuric acid is hydrophilic it will break the sucrose sugar molecule apart. The water will rise as steam above the beaker.
The sugar will turn brown and the a black carbon cone will rise out of the sugar sulfuric acid solution. The carbon cone will rise about the top of the beaker.
This experiment shows that the carbohydrate sugar is made of only Carbon and Water.

2.408 × 10²¹ is the correct answer!!b. If you have 50 grams of Molybdenum-99, how many grams will remain
after 11 days?
Answer:
6.25gm
half life is 66hrs 11 days is 24*11 then take that and divide by 66 to find out how many time it will have halved and half 50 by that many times
Explanation:
If you have 50 grams of Molybdenum-99, after 11 days, 2.7 g will remain.
Molybdenum-99 follows first-order decay.
What is first-order decay?First-order decay means that for a population of atoms (e.g. radioactive), molecules, or anything else, a constant fraction/unit time is converted to something else.
The half-life (th) of Mo-99 is 66 h.
We will find its rate constant (k) using the following expression.
k = ln2 / th = ln2 / 66 h = 0.011 h⁻¹
Next, we will convert 11 days to hours, knowing that 1 day = 24 h.
11 d × 24 h/1 d = 264 h
If we start with 50 g of Mo-99, we can calculate the remaining mass after 264 h using the following expression.
[tex][Mo] = [Mo]_0 \times e ^{-k \times t} }\\\\[Mo] = 50g \times e ^{-0.011 h^{-1} \times 264 h} } = 2.7 g[/tex]
where,
[Mo] is the final amount of Mo-99.[Mo]₀ is the initial amount of Mo-99.t is the elapsed time.If you have 50 grams of Molybdenum-99, after 11 days, 2.7 g will remain.

-Assume that the density of water it 1.000 g/cm^3
-The specific heat capacity for water is 4.184 J/g °C
Answer:
[tex]T_f=72.5\°C[/tex]
Explanation:
Hello!
In this case, since this a problem in which the cold water is heated by the hot water, we can write:
[tex]Q_{hot}+Q_{cold}=0[/tex]
Thus, by plugging in the mass, specific heat and temperatures, we obtain:
[tex]m_{hot}C_{hot}(T_f-T_{hot})+m_{cold}C_{cold}(T_f-T_{cold})=0[/tex]
Now, we can also write:
[tex]m_{hot}(T_f-T_{hot})+m_{cold}(T_f-T_{cold})=0[/tex]
Then, after applying some algebra, it is possible to obtain:
[tex]T_f=\frac{m_{hot}T_{hot}+m_{cold}T_{cold}}{m_{hot}+m_{cold}}[/tex]
If we plug in, we obtain:
[tex]T_f=\frac{350.0g*95.0\°C+150.0g*20.0\°C}{350.0g+150.0g}[/tex]
[tex]T_f=72.5\°C[/tex]

How might a rock form very quickly, and then remain stable, or unchanged, for a very long period of time? Include a specific example in your explanation.
Answer:
igneous rocks
Explanation:
One type of rock that forms very quickly would be igneous rocks. These are rocks that form after a volcanic eruption, where the molten magma melts everything into lava which then hardens shortly after. This creates a new rock that is a mixture of many other materials called Igneous rocks. Once hardened they usually remain stable and unchanged for a very long time until the next volcanic eruption. An example if the eruption of Tambora which after finishing has created lots of igneous rocks and has not erupted again since 1815.
A rock form easily through volcanic eruption, and remain stable, or unchanged, for a very long period of time because of strong bonding in constitute minerals.
What is rock?Rock is a solid substance which is naturally occur in the environment, it is made up from minerals. Mainly three types of rocks are present, which are igneous rock, metamorphic rock and sedimentary rock.
We obtain rocks generally by the volcanic eruption and as it is made up of minerals and different minerals have different crystal structure and bonding in these minerals are very strong which not break easily. That's why rocks remain stable or unchanged for a very long time. Only volcanic eruption will break rocks because only they have that much of energy to break. Examples of hard rocks are granite, syenite, unikite, andesite, etc.
Hence, due to strong bonds rocks will stay stable for long time.

A certain substance has a heat of vaporization of 64.08 kJ/mol. At what Kelvin temperature will the vapor pressure be 6.50 times higher than it was at 355 K?
Answer:
[tex]T_2 =388.50K[/tex]
Explanation:
Given
[tex]p_1 = ??[/tex] -- Initial vapour pressure
[tex]p_2 = 6.50p_1[/tex] --- Final vapour pressure
[tex]T_1 = 355K[/tex] ---- Initial temperature
[tex]T_2 = ??[/tex] --- Final temperature
[tex]\triangle _{vap}H = 64.08kJmol[/tex] --- Enthalpy of vaporization
Required
Calculate T2
To do this, we make use of Clausius-Clapeyron equation.
Which states that:
[tex]ln(\frac{p_2}{p_1}) = \frac{\triangle _{vap}H}{R}(\frac{1}{T_1} - \frac{1}{T_2})[/tex]
Where:
[tex]R = 8.314 J.K^{-1}mol^{-1}[/tex] --- Universal Gas constant
[tex]\triangle _{vap}H = 64.08kJmol[/tex]
[tex]\triangle _{vap}H = 64080\ kJmol[/tex]
[tex]ln(\frac{p_2}{p_1}) = \frac{\triangle _{vap}H}{R}(\frac{1}{T_1} - \frac{1}{T_2})[/tex] becomes
[tex]ln(\frac{6.50p_1}{p_1}) = \frac{64080}{8.314}(\frac{1}{355} - \frac{1}{T_2})[/tex]
[tex]ln(\frac{6.50p_1}{p_1}) = 7707.48(\frac{1}{355} - \frac{1}{T_2})[/tex]
[tex]ln(6.50) = 7707.48(\frac{1}{355} - \frac{1}{T_2})[/tex]
[tex]1.872 = 7707.48(\frac{1}{355} - \frac{1}{T_2})[/tex]
Take LCM
[tex]1.872 = 7707.48(\frac{T_2 - 355}{355T_2})[/tex]
[tex]1.872 = 7707.48*\frac{T_2 - 355}{355T_2}[/tex]
[tex]1.872 = \frac{7707.48*(T_2 - 355)}{355T_2}[/tex]
Cross Multiply
[tex]355T_2*1.872 = 7707.48*(T_2 - 355)[/tex]
[tex]664.56T_2 = 7707.48T_2 - 2736155.4[/tex]
Collect Like Terms
[tex]664.56T_2 - 7707.48T_2 =- 2736155.4[/tex]
[tex]-7042.92T_2 =- 2736155.4[/tex]
Make T2 the subject
[tex]T_2 =\frac{- 2736155.4}{-7042.92}[/tex]
[tex]T_2 =388.497299416[/tex]
[tex]T_2 =388.50K[/tex]
The final temperature is 388.50K
The temperature at which the vapor pressure will be 6.50 times higher than it was at 355K is 389 K
The Clausius-Clapeyron Equation is widely used for the determination of the vapor pressure of another temperature, provided we know the vapor pressure at a certain temperature as well as the heat of vaporization.
Given that:
the heat of vaporization [tex]\mathbf{\Delta H_{vap} = 64.08 \ kJ/mol = 64.08 \times 10^3 J/mol}[/tex] the initial temperature T₁ = 355 Kthe final temperature T₂ = ???if the pressure at T₁ = P₁then, the pressure at T₂ = 6.5P₁the universal gas constant = 8.314 J/K/molBy using the Clausius-Clayperon Equation:
[tex]\mathbf{In \Big( \dfrac{P_2}{P_1} \Big) = \dfrac{\Delta H_{vap}}{R} \Big (\dfrac{1}{T_1} - \dfrac{1}{T_2} \Big) }[/tex]
[tex]\mathbf{In \Big( \dfrac{6.5P_1}{P_1} \Big) = \dfrac{64.08 \times 10^3 }{8.314} \Big (\dfrac{1}{355} - \dfrac{1}{T_2} \Big) }[/tex]
[tex]\mathbf{In(6.5)=7707.48 \Big (\dfrac{1}{355} - \dfrac{1}{T_2} \Big) }[/tex]
[tex]\mathbf{1.872 =21.71 - \dfrac{7707.48}{T_2} }[/tex]
[tex]\mathbf{\dfrac{7707.48}{T_2} = 21.71- 1.872 }[/tex]
[tex]\mathbf{\dfrac{7707.48}{T_2} = 19.838 }[/tex]

Determine the molecular formula for a compound that has a molecular mass of 52.0 g/mole
and and is composed of 92.31% carbon and 7.69% hydrogen.
Answer:

Explanation:
92.31% of 52.0 g/mol is 48.0012 g/mol
7.69% of 52.0 g/mol is is 3.9988 g/mol
Carbon has a gram-formula mass of about 12, which goes into 48.0012 about 4 times, so there should be 4 atoms of Carbon

If a scientist wanted to create 10L of hydrogen gas at RTP, what mass of HCl would they need to start with?
Answer:
First write the balanced equation for the reaction of HCl with Zn (NOTE: the previous answer did NOT do this and thus obtained an incorrect answer)
Zn + 2HCl ==> ZnCl2 + H2(g)
moles of H2 desired: PV = nRT
n = PV/RT = (1 atm)(10L)/(0.0821 Latm/Kmol)(298K)
n = 0.409 mole H2 desired
moles Zn needed:
0.409 moles H2 x 1 mole Zn/2 moles HCl = 0.204 moles Zn needed
