44.8 L
45.00 L
89.55 L
89.6 L

Answers

Answer:

89.6 L of O₂

Solution:

The balanced chemical equation is as,

CH₄ + 2 O₂ → CO₂ + 2 H₂O

As at STP, one mole of any gas (Ideal gas) occupies exactly 22.4 L of Volume. Therefore, According to equation,

44 g ( 1 mol) CO₂ is produced by = 44.8 L (2 mol) of O₂

So,

88 g CO₂ will be produced by = X L of O₂

Solving for X,

X = (88 g × 44.8 L) ÷ 44 g

X = 89.6 L of O₂

Took a guess and got it right!

D) 89.6 L

Which of the following is true about the neutrons of an atom?A. The neutrons of an atom are the only subatomic particles that are involved in the interaction between two atoms.

B. The neutrons do not affect the mass or stability of an atom's nucleus, but they are involved in most interactions between two atoms.

C. The neutrons do not affect how the atom interacts with other atoms, but they do have an effect on the mass and stability of the nucleus.

Answers

I think the correct answer is C. Neutrons do not affect how atoms bond due to their neutral charge which makes it so that they don't affect the movement of electrons at all (chemical reactions occur when electrons are transferred/shared). Neutrons due however have a mass similar to that of a proton which means they contribute to the mass of the atom. Neutrons also effect the stability of the nucleas as shown in atoms that have radioactive isotopes. I hope this helps. Let me know if anything is unclear.

According to the work of the Curies, which action would increase the radioactivity of polonium?a. Dissolve the polonium in a solvent.
b. Heat the polonium until it becomes a gas.
c. Expose the polonium sample to light.
d. Increase the amount of polonium.

Answers

Answer;

Increase the amount of Polonium

Explanation;

Pierre and Marie Curies are known for their work in the study of radioactivity that led to the discoveries of new radioactive elements radium and polonium. Polonium was named after Marie's home country, Poland.
Polonium is a rare natural element, it may be found in uranium ores which is uneconomical to extract. Therefore, it is obtained from the bombarding of bismuth-209 with neutron to get bismuth-210, which then undergoes radioactive decay to form Polonium.
According to Curies increasing the amount of polonium would increase the radioactivity of Polonium element. Polonium undergoes alpha decay to emit alpha particle and is therefore used as a source of alpha particles.

Of Course D) Increase the amount of Polonium.
You want "Increase" the Radioactivity, And since Polonium is himself radioactive, you need to increase its amount.

Hope this Helps :)

When 20. milliliters of 1.0 M HCL is diluted to a total volume of 60. milliliters, the concentration of the resulting solution is 1. 1.0 M 2. 0.50 M 3. 0.33 M 4. 0.25 M

Answers

The concentration of the resulting solution is 0.33 M. The correct option is 3. 0.33 M

Dilution

From the question, we are to determine the concentration of the resulting solution

From the dilution law,

M₁V₁ = M₂V₂

Where M₁ is the initial concentration

V₁ is the initial volume

M₂ is the final concentration

V₂ is the final volume

From the given information

M₁ = 1.0 M

V₁ = 20 mL

M₂ = ?

V₂ = 60 mL

Then,

1 × 20 = M₂ × 60

20 = M₂ × 60

Therefore,

M₂ = 20 ÷ 60

M₂ = 0.33 M

Hence, the concentration of the resulting solution is 0.33 M. The correct option is 3. 0.33 M

C₁ * V₁ = C₂ * V₂

1.0 * 20 = C₂ * 60

20 = C₂ * 60

C₂ = 20 / 60

C₂ = 0.33 M

F the solution described in the introduction is cooled to 0 ∘c, what mass of kno3 should crystallize?

Answers

Assuming the other part of the question is;

A solid mixture consists of 44.2g of KNO3 (potassium nitrate) and 7.8g of K2SO4 (potassium sulfate). The mixture is added to 130. g of water. (Assume KNO3 has a solubility of 14 g solute/ 100 g water)

Answer;

26 g

Solution;

-X g of KNO3/ 130 g water= 14 g of KNO3/ 100 g water

X= 18.2 g (this is the amount of solute that dissolves at 0 degrees C in 130 g water).

if you have 44.3g of KNO3 in 130 g of water at 0 degrees celsius and only 18.2 can dissolve then

44.2g - 18.2g = 26 g left undisolved which gives you the amount that would crystallize

KNO3 of 10g will undergo crystallization at 0 °

Because the heavier the KNO3 mass will require a higher temperature in the dissolution process.

Further explanation

Potassium nitrate is a nitrate salt compound from potassium with the molecular formula KNO3. Potassium nitrate salt can be made by reacting potassium chloride with sodium nitrate. If the saturated solution each of the solution is mixed with each other, then it will form sodium chloride salt because NaCl in water is small, the salt will settle. By cooling the filtered filtrate KNO3 will undergo crystallization

This compound decomposes with oxygen evolution at 500 ° C according to the reaction equation:

2 NaNO3 (s) -> 2NaNO 2 (s) + O2 (g)

Crystallization is separation by forming crystals so that the mixture can be separated. A gaseous or liquid substance can cool or condense and form crystals because it undergoes a crystallization process. Crystals will also form from a solution that will be saturated with a certain solvent. The more the number of crystals, the better, because the less likely to be polluted by dirt.

Potassium Nitrate has a physical white powder that is easily soluble in water and odorless. Meanwhile, to analyze the structure and characteristics of Potassium Nitrate MM2 data processing is used in the Chemoffice 15.0 application. This data processing is used to determine the shape of compounds, types of bonds in molecular movement compounds and other parts that can not be observed directly by the eye without the aid of tools. And for the form of compounds in 2 dimensions and 3 dimensions used Chemdraw 15.0 and Chem3D 15.0 applications
