Answer:
We are releasing the stored carbon into the atmosphere
Explanation:
We are releasing the stored carbon into the atmosphere, thus increasing the amount of CO2 in the atmosphere. We are releasing the carbon stores faster than they can be replenished by nature.
Our use of carbon stores increases the amount of carbon dioxide in the atmosphere.
What are carbon stores?Carbon stores are those places present in the environment in which carbon is present in its different composition.
As it is present in the soil in the form of organic molecules and as a deposit in the sedimentary rocks of earth such as limestones, dolomite and in the deep oceans. If we uses these carbon stores then as a result carbon dioxide releases in the environment and increases its level.
Hence amount of carbon dioxide increases.

3. Move the slider on the burette to the top to add about 25 mL of NaOH to the flask. What
happens, and what does this tell you about the pH of the flask?
Page Break
LED
Answer:
When you move the burette slider to the top of a flask and add about 25 mL of NaOH to the flask, you will cause a concentration of OH- molecules. This will make the solution become a basic solution and make the litmus paper blue.
Explanation:
After reading your question, we can see that you are carrying out a test to discover the nature of the pH of a solution. This type of test uses litmus paper, which is an indicator of the presence of acids and bases, being able to determine the pH of a solution. This paper is soaked in organic ink and when placed in an acidic solution, it is red in color. However, when placed in a basic solution it has a blue color.
An acidic solution is one that has a high concentration of H+ atoms and has the ability to donate electrons. The basic solution, on the other hand, has a high concentration of OH- and has the capacity to receive electrons.
When you move the burette slider to the top of a flask and add about 25 mL of NaOH to the flask, you will cause a concentration of OH- molecules. This will make the solution become a basic solution and make the litmus paper blue, that is, the solution has the basic pH.
Toma en cuenta los textos para responder estas interrogantes: ¿Consideramos que la aplicación de las medidas de seguridad depende de las características de tu entorno?
Answer:
Si.
Explicación:
Sí, la aplicación de medidas de seguridad depende de las características de su entorno porque el entorno nos brinda para elegir las medidas de seguridad. Existen diferentes instrumentos utilizados para la seguridad de diferentes entornos. Algunas medidas de seguridad se aplican en un entorno mientras que el otro se aplica a otro entorno. Por ejemplo, el vallado es una medida de seguridad que se puede aplicar en el terreno pero no en el agua o cualquier zona fangosa, por lo que podemos decir que las características físicas deciden qué medida de seguridad se debe instalar en el entorno.

Answer:
0.047 moles
Explanation:
From the question,
Applying
PV = nRT............. Equation 1
Where P = Pressure of CH₄ gas, V = Volume of CH₄ gas, n = number of moles of CH₄ gas, R = Molar gas constant.
make n the subject of the equation
n = PV/RT............. Equation 2
Given: P = 660 torr = (660×0.00131579) atm = 0.868 atm, V = 1300 mL = (1300/1000) L = 1.3 L, T = 20 °C = (20+273) K = 293 K
Constant: R = 0.082 atm.dm³/K.mol
Substitute these values into equation 2
n = (0.868×1.3)/(0.082×293)
n = 1.1284/24.026
n = 0.047 mole
HI dissociates to form 12 and Hz: 2HI(g) → H2(g) + 12(9) If the concentration of Hl changes at a
rate of -0.45 mol L's? what is the rate of appearance of 12(g)?
Based on the rate of disappearance of HI, the rate of appearance of I₂ is 0.225 mol/L/s.
What is rate of reaction?
The rate of a reaction is the rate at which reactant molecules are converted to product or the rate at which product molecules are formed.
Rate of reaction = change in concentration of reactant or product/timeFrom the equation of the reaction, 2 moles of HI produces 1 mole of I₂.
The rate of disappearance of HI is -0.45 mol/L/s
The rate of appearance of I₂ will be 0.45/2 mol/L/s = 0.225 mol/L/s.
Therefore, the rate of appearance of I₂ is 0.225 mol/L/s.

A ballon is filled with 1.22 L of gas at 286 K is heated until the volume is 2.86 L while the pressure remains constant. What is the temperature of the gas in kelvin?
Answer:
670.45 K
Explanation:
Given that,
Initial volume, V₁ = 1.22 L
Initial temperature, T₁ = 286 K
Final volume, V₂ = 2.86 L
We need to find the new temperature of the gas. The relation between the volume and the temperature is given by :
[tex]\dfrac{V_1}{T_1}=\dfrac{V_2}{T_2}\\\\T_2=\dfrac{V_2T_1}{V_1}\\\\T_2=\dfrac{2.86\times 286}{1.22}\\\\T_2=670.45\ K[/tex]
So, the new temperature of the gas is equal to 670.45 K.

Write two paragraphs about what would happen if your whole body was put in a low pressure environment ?
Answer:
Reduced air pressure also has a serious effect on the human body. Reduced air pressure means that there is less oxygen available to the body. For lungs to inflate, the air pressure in your lungs has to be less than the air outside the lungs. This is because air moves from high-pressure areas to low-pressure areas.

If 34.2 g of NaOH are dissolved in water to make a 750 mL solution, what is the molarity of the solution?
Answer:
1.14 M
Explanation:
First divide the mass of NaOH by the molar mass of NaOH. Then divide by the volume to get molarity.
34.2 g / 39.997 g/mol = 0.855 mol NaOH
0.855 mol NaOH / 0.750 L = 1.14 M NaOH
Describe how the freeze-thaw cycle of ice will change the shape of this rock over time. PLSSSS HELP ASAP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!✋
Freeze-Thaw Weathering
This action can widen the cracks in the rock, and when the temperature rises above freezing, the ice thaws, allowing the water to seep further into the cracks. As this process of freezing and thawing happens repeatedly, the rock begins to weaken and eventually breaks apart into angular fragments.
Answer:
Physical weathering is caused by the effects of changing temperature on rocks, causing the rock to break apart. The process is sometimes assisted by water. ... Freeze-thaw occurs when water continually seeps into cracks, freezes and expands, eventually breaking the rock apart.

If the hydroxide ion concentration of a solution is 3.26 x 10-6 M, is it an acidic or a basic solution?
Answer: It is a basic solution with pH =8.51
Explanation:
We were given that hydroxide ion concentration [OH-] as 3.26 x 10-6 M
But We know thar
[OH-] [H+] = 1 × 10^-14
To get the Hydrogen ion [H+] concentration, we have that
[H+] = 1 × 10^-14 M/[OH-]
= 1 × 10^-14 M/3.26 x 10-6 M
= 3.067 x 10^-9 M
But, pH = - log [H+]
Therefore,
pH = - log (3.067 x 10^-9)
pH=8.51
when pH > 7, The solution is basic, therefore a solution with pH =8.51 is basic.

Answer:
149.79
Explanation:
Formula
Joules = m * c * delta (t)
Givens
J = 28242
m = ?
c = 4.19
Δt = 63 - 18 = 45
Solution
28242 = m * 4.19 * 45
28242 = m * 188.55
m = 28242 / 188.55
m = 149.79
