Answer:

[tex]less \: than \: 10 \: litres \: [/tex]

Explanation:

At 100℃,P=1atm

V=10L

At NTP, T=20

P=1atm

PV=nRT

PV=nRTV∝C

So at NTP temp is less than 100℃ and as the volume is proportional to temperature.

So at NTP temp is less than 100℃ and as the volume is proportional to temperature.Thus, the volume will be less than 10L as the temperature decreases.

Answer:

3.2×10^-3 mol

Explanation:

The equation for molarity is M= n/L. Where "M" is Molarity, "n" is the number of moles of solute, and "L" is the total liters in solution.

The question gives you the volume in mL, so to convert "mL" to "L" you need to divide by 1000. (6.70mL/ 1000L)= 0.0067L.

Now you can plug the numbers into the equation. 0.480M= n/ 0.0067L), multiply (0.480M×0.0067L)= 0.003216 mol. The scientific notation is 3.2×10^-3, 10^-3 because you move the decimal back three times and 3.2 because there are 2 sig figs.

Explanation:

The reproduction of hydra is through budding process from its body. This process of regeneration is called mitosis.Mitosis is a type of cell division process. Thus option A is correct.

Mitosis is a cell division process in which one cell produces two identical daughter cells. The term mitosis means the duplication of the genetic material chromosomes with the exact gene information.

Different stages in mitosis together is called mitotic phases. Hydra is an invertebrate freshwater organism. Hydra has a translucent tubular body which can be elongated and contracted.

Hydra is classified to the phylum hydrozoa. It have a regeneratable head. The reproduction of hydra is through budding. A small bud first projects from its tubular body which then develops and emerges out by cell division.

The divided daughter hydra will grow as a matured hydra. This overall budding process takes places through mitosis. Hence, option A is correct.

Considering the definition of molarity, 0.4375 moles of iron(II) nitrite you would recover.

In order to find the moles of the solid that can be recovered from this solution, you need to use the definition of molarity.

Molar concentration or molarity is a measure of the concentration of a solute in a solution and indicates the number of moles of solute that are dissolved in a given volume.

The molarity of a solution is calculated by dividing the moles of solute by the volume of the solution:

[tex]Molarity=\frac{number of moles}{volume}[/tex]

Molarity is expressed in units [tex]\frac{moles}{liters}[/tex].

Moles of iron(II) nitrite

In this case, you evaporated 125 mL of a 3.5 M solution of iron(II) nitrite​. Then you know:

Replacing in the definition of molarity:

[tex]3.5 M=\frac{number of moles}{0.125 L}[/tex]

Solving:

number of moles= 3.5 M× 0.125 L

number of moles= 0.4375 moles

Finally, 0.4375 moles of iron(II) nitrite you would recover.

Answer:

High pressure and low pressure have two distinct types of weather associated with them...typically. High pressure often means dry weather with sunshine. Low pressure often means clouds and precipitation. High pressure is associated with sinking air.

Explanation:

High-pressure systems are usually called Fair Weather Systems because the 7 types of weather in a high-pressure zone are generally comfortable and clear. Keep in mind that high and low pressures mean the air is under higher or lower pressure relative to the surrounding air.

Given Information ,

We have to find the number of moles .

We use here " Ideal Gas Equation" which is

where

n is number of moles

R is universal gas Constant

T is temperature

P is pressure

V is volume

On substituting the value we get

➣ 2.2 × 58 = n × 0.0821 × 313

➣ 127.6 = n × 25.70

➣ 127.6/25.70 = n

➣ 4.96 = n

➣ 5 ≈ n

So, the number of moles are 5 .

This problem is providing the initial volume and pressure of a gas in an engine cylinder and asks for the final pressure once the volume of the gas has decreased due to a compression. At the end, the result turns out to be 11.7 atm.

In chemistry, gas laws allow us to calculate pressure, volume, temperature or moles depending on a specified change and based on the concept and equation of the ideal gas, which derives the well-known gas laws; Boyle's, Charles', Gay-Lussac's and Avogadro's.

Thus, since this problem provides initial and final volume and initial pressure for us to calculate the final pressure, we understand we need to apply the Boyle's law as a directly proportional relationship between these two:

[tex]P_1V_1=P_2V_2[/tex]

Thus, we solve for the final pressure, P2, to get:

[tex]P_2=\frac{P_1V_1}{V_2}=\frac{1.0atm*175mL}{15mL}\\ \\ P_2=11.7atm[/tex]

This problem is providing the rate of the given reaction as 0.840 M/s and asks for the relative rate of change of each species. At the end, the results turned out to be -0.840 M/s, 0.210 M/s and 0.420 M/s for A, B and C respectively.

In chemical kinetics, when chemical reactions take place, it turns out possible for us to quantify in what extent a reaction is proceeding over time, by overseeing the change in the concentration as the time goes by.

In such a way, when given the rate of reaction, one can calculate the relative rate of change of each species by using the following equation, involving their stoichiometric coefficients in the reaction:

[tex]r_A=\frac{r}{-1} \\\\r_B=\frac{r}{-4} \\\\r_C=\frac{r}{2}[/tex]

Where these coefficients are negative for reactants and positive for products. In such a way, one can plug in the given rate of reaction to obtain each species' as follows:

[tex]r_A=\frac{0.840M/s}{-1} =-0.840M/s\\\\r_B=\frac{0.840M/s}{-4} =0.210M/s\\\\r_C=\frac{0.840M/s}{2}=0.420M/s[/tex]

Answer:

B)   n2=V2N1/V1

the second part is 0.080

Explanation:

EDGEEEEE

The volume and number of moles of a gas are in direct proportion. Hence, as the volume increases from 5 ml to 1 L, number of moles increases from 0.040 to 8 moles.

Avogadro's law, states that, at constant pressure and temperature, the number of moles of a gas is directly proportional to the volume of the gas. Hence,

V1/n1 = V2/n2, for two different volumes.

Given that, v1 = 5 ml

v2 = 1 L = 1000 ml

n1 = 0.040 mol

then n2 = v2 n1/ v2

Number of moles at 1 L = (0.040 mol × 1000 ml)/5 ml = 8 moles.

Hence, the number of moles of the gas added  = 8 - 0.040 = 7.96 moles.

Therefore, the amount of gas added at the increased volume is 7.96 moles.
