The answer is false.

Explanation:

Precipitation is the process where water released from clouds in the form of rain, freezing rain, sleet, snow, or hail. It is the primary connection in the water cycle that provides for the delivery of atmospheric water to the Earth.

Answer: Mass of solution is 80.4 g

Explanation: 15.8 % = 0.158.   Mark mass of solution with x

You can make an equation for mass of sugar: 0.158 x = 12.7 g

x = 12.7 g / 0.158

Got it right on the quiz, hope this helps :)

Answer:

m_r = 125 g

Explanation:

Formula to calculate the remaining mass is;

m_i = m_r × 2^(t/λ)

Where;

m_i is initial mass of sample

m_r is remaining mass after time t.

t is time

λ is half life.

We are given;

m_i = 1000 g

t = 15.9 years

λ = 5.3 years

Thus;

1000 = m_r × 2^(15.9/5.3)

1000 = 8m_r

m_r = 1000/8

m_r = 125 g

Answer: Synthesis

Explanation: I think is suynthesis

Answer:

Explanation:

Na₂S₂O₃ + 4Cl₂ + 5H₂O → 2NaHSO₄ + 8HCl.

                4 moles                               8 moles

4 moles of Cl₂ forms 8 moles of HCl

.25 moles of Cl₂ forms 8 x .25 / 4 moles of HCl

HCl formed = .50 moles .

E is the answer .

Answer:

You must change the size of each ingredient by the size of the product. Let's say my recipe calls for 1 bag of flower and 2 eggs. I want to double the amount of product that I make, so I must multiply each of my ingredients by 2. I would now use 2 bags of flower and 4 eggs.

Answer: In a vacuum, the objects fall at the same rate independent of their respective masses. That means coin and feather both reach ground at same time in a vacuum. Larger objects experience more air resistance than smaller objects. Also, the faster an object falls, the more air resistance it encounters.

Explanation:

Answer:

D

Explanation:

Gases have low densities. Density is the mass of an object divided by its volume. Mass of gases are quite small. Since the mass is related to mass of the particles itself. However the volume is great since the gases are far apart due to how weak the forces of attraction are ( gases take the shape of the container which means they take up a good bit of space which means greater volume). A small mass divided by a large volume gives a small value (small density).

Answer:

Breaking a match in two pieces is an example of a physical change. Lighting a match and letting is burn is an example of a chemical change. Chemical reactions cause chemical changes. In a chemical reaction two or more substances, called the reactants, form different substances called products.

Solid, liquids and gases

Answer:

Solid, liquids and gases

Explanation:

Answer: A. the outer core is more dense and farther from the surface than the mantle

Explanation: There are two mantle‘s. But both of them are closer to the surface than the outer core. the outer core is the liquid layer outside of the inner core. The mantle is the next layer after the outer core. It goes: inner core, outer core, stiffer mantle, asthenosphere, ridged mantle, then the earth’s crust.

Answer:

The pH of the solution is 11.48.

Explanation:

The reaction between NaOH and HCl is:

NaOH  +  HCl  →  H₂O  +  NaCl

From the reaction of 3.60x10⁻³ moles of NaOH and 5.95x10⁻⁴ moles of HCl we have that all the HCl will react and some of NaOH will be leftover:

[tex] n_{NaOH}} = n_{i_{NaOH}} - n_{HCl} = 3.60 \cdot 10^{-3} moles - 5.95 \cdot 10^{-4} moles = 3.01 \cdot 10^{-3} moles [/tex]

Now, we need to find the concentration of the OH⁻ ions.

[tex] [OH^{-}] = \frac{n_{NaOH}}{V} [/tex]

Where V is the volume of the solution = 1.00 L                

[tex] [OH^{-}] = \frac{n_{NaOH}}{V} = \frac{3.01 \cdot 10^{-3} moles}{1.00 L} = 3.01 \cdot 10^{-3} mol/L [/tex]

Finally, we can calculate the pH of the solution as follows:

[tex] pOH = -log([OH^{-}]) = -log(3.01 \cdot 10^{-3}) = 2.52 [/tex]

[tex] pH + pOH = 14 [/tex]

[tex] pH = 14 - pOH = 14 - 2.52 = 11.48 [/tex]

Therefore, the pH of the solution is 11.48.

Answer:

the ability for a given substance, the solute to dissolve in a solvent is solubility.

Answer:

The atoms become cations because they have lost electrons and the atoms and has a positive charge then atoms become a ions because they have gained electrons from cations and has a negative charge

Answer:

is simple apply formula dude.

Answer:

Smashing the cube into pieces

Explanation:

The reason for this is that if we were to smash the cube we would have a larger surface area which means more manganese oxide would be dissolving per second which means we would have a faster reaction rate where if we were to chill the peroxide it would dissolve slower which in turn slows the reaction. For example a spoonful of granulated sugar will react with water faster than a sugar cube.

The rate of the reaction is increased by smashing the cube into pieces. C is the correct answer.

The reaction rate, also known as the rate of reaction, is the rate at which a chemical reaction occurs.

It is typically classified as proportional to the change in product concentration per unit time and the change in reactant concentration per unit time. Different chemical reactions have different reaction rates.

The amount of reactants, the temperature, and the catalyst all influence the reaction rate.

When a cube of manganese oxide was added to a solution of hydrogen peroxide, water and oxygen were produced, just as in the given reaction. The reaction did not deplete manganese oxide.

The reaction will be altered by smashing the cube into pieces as the it can boost appropriate conditions for the reaction.

Thus, C is the correct answer.
