Answer:

a variable (often denoted by x ) whose variation does not depend on that of another.

Explanation:

You can think of independent and dependent variables in terms of cause and effect: an independent variable is the variable you think is the cause, while a dependent variable is the effect. In an experiment, you manipulate the independent variable and measure the outcome in the dependent variable.For example, someone's age might be an independent variable. Other factors (such as what they eat, how much they go to school, how much television they watch) aren't going to change a person's age.

Answer:

Nuclear reactions involve a change in an atom's nucleus, usually producing a different element. Chemical reactions, on the other hand, involve only a rearrangement of electrons and do not involve changes in the nuclear.

Salts with nitrates as the anion are generally soluble in water. The question isn’t quite clear: Are we being asked what precipitate would form if these solutions were mixed together? If that’s the case, the reaction would be as follows:

Li3AsO4(aq)+ Fe(NO3)3(aq) → 3LiNO3(aq) + FeAsO4(s).

It is odd that we’re given lithium arsenate dissolved in water to begin with as lithium arsenate should be insoluble. But assuming that it is water-soluble, we can obtain the net ionic equation for the formation of our precipitate:

Fe3+(aq) + [AsO4]3-(aq) → FeAsO4(s).

Our precipitate would be iron(iii) arsenate, FeAsO4.

Answer:

The balanced equation would be 2H2 + O2 -> 2H2O

Explanation:

The correct balanced equation is 2H₂ + O₂  →  2H₂O, and  the correct coefficient for O₂ is 1.

Count the atoms on each side first. Next, alter one of the compounds' coefficient. Third, count the atoms once more, and then repeat steps two and three until the equation is balanced.

In the given equation, hydrogens are already balanced. To balance oxygen, multiple water with 2. Thus, equation becomes:

H₂  + O₂  →  2 H₂O

Now, oxygen is balanced, just the hydrogens got unbalanced. To balance hydrogen, multiply the hydrogen by 2 on the left side.

2 H₂ + O₂  → 2H₂O

Now the chemical equation is balanced, in which the number of oxygen and hydrogen are equal on both sides of the arrow.

Therefore, the coefficient of O₂ is 1.

Answer:

true

Explanation:

Answer:

7. Convection

8. Radiation

9. Conduction

Explanation:

Convection is when a fluid, such as air or a liquid, is heated and then travels away from the source, it carries the thermal energy along.

Radiation is the energy that is emitted by matter in the form of photons or electromagnetic waves. So, it is coming off the fire which makes it radiation.

Conduction is the process by which heat or electricity is directly transmitted through a substance when there is a difference of temperature or of electrical potential between adjoining regions, without movement of the material. Because the picture shows different temperatures, it leds to the conclusion that 9 is conduction.

Answer: If the solubility of sodium chloride is 36 grams per 100 grams of water then 5.8 moles of NaCl dissolved in 1 L of water solution would be considered unsaturated.

Explanation:

A solution which contains the maximum amount of solute is called a saturated solution. Whereas a solution in which more amount of solute is able to dissolve is called an unsaturated solution.

Now, the number of moles present in 36 g of NaCl (molar mass = 58.4 g/mol) is as follows.

[tex]No. of moles = \frac{mass}{molar mass}\\= \frac{36 g}{58.4 g/mol}\\= 0.616 mol[/tex]

This shows that solubility of sodium chloride is 36 grams per 100 grams of water means a maximum of 0.616 mol of NaCl will dissolve in 100 mL of water.

So, a solution in which number of moles of NaCl are less than 0.616 mol per 100 mL then the solution formed will be an unsaturated solution.

[tex]Moles = \frac{5.8 mol}{1000 mL} \times 100 mL\\= 0.58 mol[/tex]

[tex]Moles = \frac{3.25 mol}{500 mL} \times 100 mL\\0.65 mol[/tex]

[tex]Moles = \frac{1.85 mol}{300 mL} \times 100 mL\\= 0.616 mol[/tex]

Thus, we can conclude that if the solubility of sodium chloride is 36 grams per 100 grams of water then 5.8 moles of NaCl dissolved in 1 L of water solution would be considered unsaturated.

Explanation:

    HOAc                   +            NaOH            =>            NaOAc              + H₂O

50ml(0.10M HOAc)  +  50ml(0.10M NaOH) => 100ml(0.05M NaOAc) + H₂O

For neutralized system, 100ml of 0.05M NaOAc remains

NaOAc => Na⁺ + OAc⁻

Na⁺ + H₂O => No Rxn

          OAc⁻  +  H₂O  => HOAc + OH⁻

C(i)   0.05M       -----        0M      0M

ΔC        -x           -----         +x        +x

C(f)    0.05-x      

       ≅ 0.05M    -----          x          x

Kb = Kw/Ka = [HOAc][OH⁻]/[OAc⁻] = 1 X 10⁻¹⁴/1.7 X 10⁻⁵ = (x)(x)/(0.05M)

=> x = [OH⁻] = SqrRt(0.05 x 10⁻¹⁴/1.7 x 10⁻⁵) = 5.42 x 10⁻⁶M

=> pOH = -log[OH⁻] = -log(5.42 x 10⁻⁶) = 5.27

pH + pOH = 14 => pH = 14 - pOH = 14 - 5.27 = 8.73 Eqv Pt pH

A sample of aluminum foil contains 9.20 x 1023 atoms, then mass of foil will be 41.24 gram.

Aluminum foil serves as a barrier to air and oxygen, which could heat up food that is cold or frozen. In the end, it is beneficial since it keeps the food's temperature, irrespective of whether it's warm or cold.

Iron and silicon make up the majority of the remaining 2.5% of aluminum foil, which gives it strength as well as puncture resistance. Between big, water-cooled chilling rollers, the molten alloy has been rolled thin as well as solidified. Two layers of foil were run through the mill simultaneously even during final rolling.

It is known that 1 mol = 6.022 × [tex]10^{23}[/tex]

and, 1 mol of aluminum = 27 g.

It is given that, count of Al atoms = 9.20 × [tex]10^{23}[/tex]

So,  9.20 × [tex]10^{23}[/tex] particle has mass = 27 /  6.022 × [tex]10^{23}[/tex]  ×  9.20 × [tex]10^{23}[/tex]

Which will be equal to 41.24gram.

Therefore, the mass of foil will be 41.24 gram.

Answer:

1.77 * 10^-3

Explanation:

From the titration formula;

Let

CA = concentration of acid

CB = concentration of base

VA = volume of acid

VB = volume of base

NA = number of moles of acid

NB = number of moles of base

The equation of the reaction is;

M(OH)2(aq) + 2HCl(aq) -------> MCl2(aq) + 2H2O(l)

So;

CAVA/CBVB= NA/NB

CAVANB = CBVBNA

CB= CAVANB/VBNA

CB= 0.173 * 25.10 * 1/28.5 * 2

CB= 4.3423/57

CB= 0.0762 M

This implies that the solubility of M(OH)2 = 0.0762 M

M(OH)2(s) ----> M^+(aq) + 2OH^-(aq)

So

Ksp = x * (2x)^2

Ksp = 4x^3

x = 0.0762

Ksp= 4(0.0762)^3

Ksp = 1.77 * 10^-3

Answer:

1) increase

2) increase

Explanation:

Entropy is the degree of disorderliness or randomness of a system. It is the measure of the unavailable energy in a system.

Entropy increases with increase in the number of particles. If the number of particles in a system increases from left to right, the entropy of the system increases accordingly.

In reaction 1, the number of particles from left to right increased from two to three hence the entropy was increased.

In reaction 2, the number of particles from left to right increased from three to five hence the entropy was increased.

Answer:

A. was the object once part of and asteroid

Explanation:

A is correct because at first asteroid's pieces fall off and burn up to enter the atmosphere and meteoroid's are small while asteroid's are big and rocky

D. Is the object made of rock? The question "Is the object made of rock?" would best confirm that the object is a meteoroid.

Meteoroids are small rocky or metallic objects that are in space and can potentially enter the Earth's atmosphere. By determining if the object is made of rock, it aligns with the characteristics of a meteoroid.

Option A, "Was the object once part of an asteroid?" does not necessarily confirm that the object is a meteoroid since meteoroids can come from various sources, not just asteroids.

Option B, "Where is the object located?" does not provide specific information about the nature of the object and can apply to comets and asteroids as well.

Option C, "Does the object orbit the sun?" is a characteristic shared by comets, asteroids, and meteoroids. It does not specifically confirm that the object is a meteoroid.
