Prophase is the first stage in mitosis, occurring after the conclusion of the G2 portion of interphase. During prophase, the parent cell chromosomes which were duplicated during S phase condense and become thousands of times more compact than they were during interphase.

Answer:

H^+(aq) + OH^-(aq) --------> H2O(l)

Explanation:

We must first obtain the molecular equation, the net ionic equation before we obtain the net ionic equation.

The molecular reaction equation is;

HF(aq) + NaOH(aq) -------> H2O(l) + NaF(aq)

The complete ionic equation is;

H^+(aq) + F^-(aq) + Na^+(aq) + OH^-(aq) --------> H2O(l) + Na^+(aq) + F^-(aq)

The net ionic equation is;

H^+(aq) + OH^-(aq) --------> H2O(l)

Answer:

1.8 J/g·°C (2 sig.figs. per ΔT)

Explanation:

Given:

mass (m) = 78.9 grams

specific heat (c) = ?

Temp. Change (ΔT) = 109°C - 18°C = 91°C

Heat flow (q) = 13,240 Joules

q = m·c·ΔT => c = q/m·ΔT

∴c = 13,240J / 78.9g·91°C = 1.844 J/g·°C ≅ 1.8 J/g·°C (2 sig.figs. per ΔT)

Answer: Volume required is 0.115 L or 115 ml

Explanation:

moles of [tex]NaHCO_3[/tex] = [tex]\frac{\text {given mass}}{\text {Molar mass}}=\frac{1.30g}{84g/mol}=0.015mol[/tex]

The balanced chemical equation is:

[tex]HCl+NaHCO_3\rightarrow NaCl+H_2CO_3[/tex]

1 mole of [tex]NaHCO_3[/tex] requires = 1 mole of HCl

Thus 0.015 mol of [tex]NaHCO_3[/tex] requires = [tex]\frac{1}{1}\times 0.015=0.015[/tex] mole of HCl

Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.

[tex]Molarity=\frac{n}{V_s}[/tex]

where,

n = moles of solute

[tex]V_s[/tex] = volume of solution in L

[tex]0.130=\frac{0..015}{V_s}[/tex]

[tex]V_s=0.115L[/tex]

Thus volume required is 0.115 l or 115 ml

Answer and Explanation:

It is not necessary to know the amount of salt in the aqua, because we know that the presence of salt in the water will increase its density.

In this case, salt increases the mass of the water, without increasing the volume of water. as the egg will not change in volume or water, we know that the density of the egg will be constant, while the change in the mass of the water with the addition of salt, will change the density of the water which will increase progressively until it becomes denser than the egg and, consequently, it will not let the egg sink.

Answer:

2.67x10⁻¹⁴M = [OH-]

Explanation:

To solve this question we need first to find the HCl concentration of the beaker 6. Then, using:

Kw = [OH-][H+]

Where Kw = 1x10⁻¹⁴

[OH-] is our incognite

[H+] is = [HCl]

Beaker 2 = 12.0M / 2 = 6.0M

Beaker 3 = 6.0M / 2 = 3.0M

Beaker 4 = 3.0M / 2 = 1.5M

Beaker 5 = 1.5M / 2 = 0.75M

Beaker 6 = 0.75M / 2 = 0.375M

HCl = 0.375M = [H+]

1x10⁻¹⁴ / [H+] = [OH-]

1x10⁻¹⁴ / 0.375M = 2.67x10⁻¹⁴M

Explanation:

Basically, phosphorolysis involves the cleavage of a bond by adding phosphoric acid across the bond, while hydrolysis involves the cleavage of a bond by adding water across the bond.

The phosphorolytic cleavage of glycogen is energetically advantageous because the released sugar is already phosphorylated. In contrast, a hydrolytic cleavage would yield glucose, which would then have to be phosphorylated at the expense of the hydrolysis of a molecule of ATP to enter the glycolytic pathway(Biochemistry, 5th ed, Jeremy M Berg et al, 2002).

Answer:

5.6 L is the final volume for SO₂ at STP condtions

Explanation:

The reaction is:  S(s) + O₂ (g) →  SO₂ (g)

Ratio for this reaction is 1:1, if we see stoichiometry.

1 mol of sulfur can react to 1 mol of oxygen in orden to produce 1 mol of sulfur dioxide.

Then, 0.250 moles of sulfur can produce 0.250 moles of SO₂.

If we solve this by a rule of three, we can say:

At STP 1 mol occupies 22.4L

Then, 0.250 moles will be contained at (0.250 mol . 22.4L) /1mol = 5.6 L

If we apply the Ideal Gases Law:

P . V = n . R . T

1 atm . V = 0.250 mol . 0.082 . 273K

V = (0.250 mol . 0.082 . 273K) / 1atm → 5.6 L

Answer: The vapor pressure of a solution in which the mole fraction of the solute is 0.200 is 80.0 torr

Explanation:

As the relative lowering of vapor pressure is directly proportional to the amount of dissolved solute.

The formula for relative lowering of vapor pressure will be,

[tex]\frac{p^o-p_s}{p^o}=i\times x_2[/tex]

where,

[tex]p^0[/tex]= vapor pressure of pure solvent = 100.0 torr

[tex]p_s[/tex] = vapor pressure of solution = ?

i = Van'T Hoff factor = 1 for nonvolatile, nonelectrolyte solute

[tex]x_2[/tex] = mole fraction of solute  = 0.200  

[tex]\frac{100.0-p_s}{100.0}=1\times 0.200[/tex]

[tex]p_s=80.0torr[/tex]

The vapor pressure of a solution in which the mole fraction of the solute is 0.200 is 80.0 torr

Answer:

630.95 grams of Na₂CO₃ would be needed to produce 1000g of NaHCO₃

Explanation:

The balanced reaction is:

Na₂CO₃ + CO₂+ H₂O → 2 NaHCO₃

By stoichiometry of the reaction (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of each compound participate in the reaction:

Being the molar mass:

Then by stoichiometry the following quantities of mass participate in the reaction:

You can apply the following rule of three: if 106 grams of Na₂CO₃ are needed to produce 168 grams of NaHCO₃, how much mass of Na₂CO₃ is necessary to produce 1000 grams of NaHCO₃?

[tex]mass of Na_{2} CO_{3}=\frac{1000grams ofNaHCO_{3} *106gramsofNa_{2} CO_{3} }{168grams ofNaHCO_{3}}[/tex]

mass of Na₂CO₃= 630.95 grams

630.95 grams of Na₂CO₃ would be needed to produce 1000g of NaHCO₃

Answer:

a. Larger molecular size

b. Ability to react with water

c. Polarity

d. Shorter bond length

Explanation:

Ethene is a larger molecule than oxygen and nitrogen hence it is more soluble than the both other gases .

SO2 dissolves readily in water to yield an acid solution. It is an acid anhydride.

Nitric oxide is a polar compound. It remains very much polar while nitrogen and oxygen are non polar.

Nitrogen is sp hybrized, this leads to a very short bond and does not easily interact with oxygen and nitrogen

The order of marbles can be Aluminum, Nickel, Silver, and Rhenium.

If volume is the amount of three-dimensional space contained by a closed surface, such as the amount of space within a given cube, cylinder, or other three-dimensional shape.

Liquid volume is a way to measure an amount of liquid by describing how much three-dimensional space it occupies.

The mass of something is the amount of stuff it is made of. The volume of an object is the amount of space it usually takes up.

Density provides an easy way to calculate a body's mass from its volume or vice versa.

The mass is equal to the volume multiplied by the density (M = Vd), and the volume is equal to the mass divided by the density (V = M/d).

As per the density given, the volume of aluminum can be 1.11mL, Silver is 0.286mL, Rhenium is 0.144mL, Nickel is 0.337mL.

Thus, the order from largest to smallest will be Aluminum, Nickel, Silver, and Rhenium.

Electromagnetic radiation is the energy waves with various wavelengths. Ultraviolet rays have the shortest wavelength. Thus, option B is correct.

A wavelength is a ratio of the velocity and the frequency as the distance between the crests is measured. The shortest wavelength haves the largest frequency.

Radio waves have the longest wavelength but the shortest frequency and similarly the gamma rays have the shortest wavelength. Ultraviolet rays come before the X-rays and the gamma rays have a short wavelength.

Therefore, option B. UV rays have the shortest wavelength.

Answer:

RCl

Explanation:

Here, let us take ROH to represent the formula of our alcohol where R is the alkyl group.

The reaction of ROH with  tosyl chloride yields an ester called a tosylate. It is the O-H bond not the C-O bond that is cleaved when the tosylate is formed.

Tosylates are good leaving groups, attack of a nucleophile such as Cl^- completes the mechanism leading to the formation of RCl.
