Liquid nitrogen can be used to freeze biological tissue. Liquid nitrogen is -210°C which will stop all biological decomposition in the tissue and preserve it.

Explanation:

Polar air is often described as dry because there is a large separation between the dew point and air temperature. This occurs because the air is usually very cold and has a low absolute humidity.

Polar air is often described as dry even though the relative humidity is high. This is because in polar regions there is a large separation between dew point and air temperature.In polar regions, the air is very cold, and therefore has very little moisture. This means that the relative humidity of the air is very high, but the actual amount of moisture in the air is very low. This is because cold air cannot hold as much moisture as warm air. When the temperature of the air drops, the amount of moisture that it can hold also decreases.

As a result, the relative humidity of the air increases, even though the actual amount of moisture in the air is very low.

The relative humidity is high because the dew point and air temperature are close together. This means that the amount of water vapor in the air is low, making it feel dry.

Answer:

The correct answer is:

(1) decreases 1 pH unit

Answer: To balance the given chemical equation, we can start by counting the number of atoms on both sides of the equation. We have 3 carbon atoms and 8 hydrogen atoms on the left side, and 3 carbon atoms, 6 X atoms, and 1 hydrogen atom on the right side.

C3H8(g) + X2(g) → C3H2X6(g) + HX(g)

To balance the equation, we can add a coefficient of 3 in front of HX on the product side:

C3H8(g) + X2(g) → C3H2X6(g) + 3HX(g)

Now, we have the same number of H atoms on both sides (8 H atoms on each side), and the equation is balanced.

To estimate the heat of reaction, we can use the bond energy values to calculate the energy required to break the bonds in the reactants and the energy released by forming the bonds in the products. We can then subtract the energy required to break the bonds from the energy released by forming the bonds to obtain an estimate of the heat of reaction.

Breaking bonds in the reactants:

3 C-H bonds × 414 kJ/mol = 1242 kJ/mol

1 X-X bond × 243 kJ/mol = 243 kJ/mol

Forming bonds in the products:

6 C-X bonds × 339 kJ/mol = 2034 kJ/mol

1 C-H bond × 414 kJ/mol = 414 kJ/mol

3 H-X bonds × 431 kJ/mol = 1293 kJ/mol

Estimated heat of reaction:

Energy released - energy required

(2034 kJ/mol + 414 kJ/mol + 1293 kJ/mol) - (1242 kJ/mol + 243 kJ/mol) = 2756 kJ/mol

Therefore, the estimated heat of reaction for the given chemical equation is 2756 kJ/mol. Note that this is only an estimate and actual experimental values may differ due to factors such as reaction conditions and the presence of catalysts.

When the pressure is 0.72 atm, the temperature in Kelvin is 156 K.

To determine the Kelvin temperature when the pressure is 0.72 atm, you will need to use the trendline equation given in Fig 6.2. First, find the equation of the trendline by using the graph's two points, (300 K, 1 atm) and (500 K, 2 atm).

The equation for the trendline is:

y = mx + b

Where y is pressure, x is the temperature in Kelvin, m is the slope, and b is the y-intercept. We can find the slope of the trendline by using the two points provided in the graph:

Slope (m) = (y2 - y1) / (x2 - x1)

Slope = (2 atm - 1 atm) / (500 K - 300 K)

Slope = 0.005 atm/K

The equation for the trendline can now be written: y = 0.005x + b. To find the y-intercept, b, we can use one of the two points: Solving for b:

1 atm = 0.005(300 K) + bb = 1.5 atm

Now we can use the equation for the trendline to find the temperature (x) at which the pressure (y) equals 0.72 atm:

0.72 atm = 0.005x + 1.5 atm

0.72 atm - 1.5 atm = 0.005x

Answer:

The dependent variable would be the whitening of the teeth of the participants.

Explanation:

The first two statements are false, whereas the last statement, which says that pressure and volume of a gas are inversely related, is true.

Statement 1: This claim was incorrect because, according to the ideal gas law, PV=nRT, pressure (P) and volume (V) are inversely proportional to each other at a constant temperature (T) and amount of gas (n). This means that as pressure increases, volume decreases. This relationship is known as Boyle's law. Therefore, the statement that pressure has no effect on volume of a gas is false.

Statement 2: This claim was incorrect because, pressure and volume of a gas are inversely related according to Boyle's law, which states that at a constant temperature, the pressure of a gas is inversely proportional to its volume. This means that if the pressure of a gas increases, its volume will decrease, and if the pressure decreases, the volume will increase, as long as the temperature remains constant.

Statement 3: This claim was correct because, According to Boyle's law, the pressure and volume of a gas are inversely proportional to each other, which means that when the pressure of a gas increases, its volume will decrease and vice versa, as long as the temperature and the number of particles in the gas are kept constant.

M2= 0,1 M

Explanation:

M1=0,15 M

V1= 100 mL =0,1 L

M2= ?

V2= 150 mL = 0,15 L

M1V1= M2V2

(0,15 mol/L) (0,1 L) = M2 (0,15 L)

0,015 mol / 0,15 L = M2

M2= 0,1 M
