before you retire in the evening, you sit down for a snack of milk and cookies. when you waken in the morning, you discover a carton of sour milk on the counter. knowing that milk sours if left in the refrigerator too long, has the reaction rate increased or decreased for the carton of milk on the counter? what has happened to its reaction time

Answers

Answer:

Increased

Explanation:

We know that the higher the temperature the higher the rate of reaction. This implies that as the temperature is increased, a reaction tends to proceed faster.

This follows from the collision theory, the higher the temperature, the higher the energy of the reacting particles hence they collide with each other faster and more effectively.

Thus the rate of reaction( or reaction time) for the carton of milk on the counter was increased.

Consider this reaction: NH4+ + HPO42− → NH3 + H2PO4−

Which is the conjugate base?

NH4+

NH3

HPO42–

H2PO4–

Answers

The NH3, as it was the acid in the beginning and donated a proton to become more basic.

The conjugate base is formed when an acid loses its hydrogen or proton. In the reaction between ammonium ion and hydrogen phosphate, HPO₄²⁻ is the conjugate base. Thus, option C is correct.

What is a conjugate base?

Conjugate bases are formed when the substance accepts or absorbs the proton or the hydrogen ion from the acids in the solution. It can be said as a base with an added hydrogen ion to it.

The chemical reaction of the acids and the bases has been shown as,

NH₄⁺ + HPO₄²⁻ → NH₃⁺ +  H₂PO₄⁻

From the reaction, it can be said that ammonia donated its proton, whereas HPO₄²⁻ accepted hydrogen ions from the acid.

Therefore, HPO₄²⁻ has been the conjugate base in the given chemical reaction.

2 K + Cl2 → 2 KCI
How many grams of KCI (74.55 g/mol) is produced from 2.50 mol of K?

Answers

Answer:  186.3 g of [tex]KCl[/tex] will be produced from 2.50 mol of K

Explanation:

The balanced chemical reaction is:

[tex]2K+Cl_2\rightarrow 2KCl[/tex]  

According to stoichiometry :

2 moles of K produce = 2 moles of [tex]KCl[/tex]

Thus 2.50 moles of [tex]K[/tex] will produce=[tex]\frac{2}{2}\times 2.50=2.50moles[/tex]  of [tex]KCl[/tex]

Mass of [tex]KCl=moles\times {\text {Molar mass}}=2.50moles\times 74.55g/mol=186.3g[/tex]

Thus 186.3 g of [tex]KCl[/tex] will be produced from 2.50 mol of K

What is a cone of depression and how is it caused?

Answers

Answer:

Depression can be caused by many things, like being neglected, abused, or even trauma. Even thoughts that might trigger sadness, or anxiety it's caused by alot of problems of your life or others around you

Explanation:

hope this helps a bit :)

A cone of depression occurs in an aquifer when groundwater is pumped from a well. In an unconfined aquifer (water table), this is an actual depression of the water levels. In confined aquifers (artesian), the cone of depression is a reduction in the pressure head surrounding the pumped well.

When a well is pumped, the water level in the well is lowered. By lowering this water level, a gradient occurs between the water in the surrounding aquifer and the water in the well. Because water flows from high to low water levels or pressure, this gradient produces a flow from the surrounding aquifer into the well.

As the water flows into the well, the water levels or pressure in the aquifer around the well decrease. The amount of this decline becomes less with distance from the well, resulting in a cone-shaped depression radiating away from the well. This, in appearance, is similar to the effect one sees when the plug is pulled from a bathtub. This conical-shaped feature is the cone of depression.

12.7 g of copper metal reacts with silver nitrate to actually produce 38.1 g of silver in the lab.

Percent Yield = Actual Yield/Theoretical Yield x 100%

What is the percent yield of silver (Ag) in this reaction?

Answers

Answer:

For these problems, we need to compare the theoretical yield that we'd get from performing stoichiometry to the actual yield stated in the problem. % yield is the actual yield/theoretical yield x 100%  

Cu + 2 AgNO₠→ Cu(NOâ‚)â‚‚ + 2 Ag ==> each mole of copper yields two moles of silver  

12.7-g Cu x ( 1 mol Cu /63.5-g Cu) x ( 2 mol Ag / 1 mol Cu) x (108-g Ag / 1 mol Ag) = 43.2-g Ag. This is the theoretical yield. Now, since we got 38.1-g Ag our % yield is:  

38.1-g/43.2-g x 100% = 88.2%

How much heat energy is absorbed when 94.0 g of water is heated from 5.0C to 29.5C? Show your work.

Answers

Answer:

In order to be able to solve this problem, you will need to know the value of water's specific heat, which is listed as

c=4.18Jg∘C

Now, let's assume that you don't know the equation that allows you to plug in your values and find how much heat would be needed to heat that much water by that many degrees Celsius.

Take a look at the specific heat of water. As you know, a substance's specific heat tells you how much heat is needed in order to increase the temperature of 1 g of that substance by 1∘C.

In water's case, you need to provide 4.18 J of heat per gram of water to increase its temperature by 1∘C.

What if you wanted to increase the temperature of 1 g of water by 2∘C ?

This will account for increasing the temperature of the first gram of the sample by n∘C, of the the second gramby n∘C, of the third gram by n∘C, and so on until you reach m grams of water.

And there you have it. The equation that describes all this will thus be

q=m⋅c⋅ΔT , where

q - heat absorbed

m - the mass of the sample

c - the specific heat of the substance

ΔT - the change in temperature, defined as final temperature minus initial temperature

In your case, you will have

q=100.0g⋅4.18Jg∘C⋅(50.0−25.0)∘C

q=10,450 J

List several other words that are formed using the prefix mon or mono what do these words have in common

Answers

Answer:

1) Monochrome

2) Monocot

3) Monosaccharide

4) Monounsaturated

5) Monoxide

Explanation:

The prefix mono or mon is of Greek origin and it means single, lone or one.

From the meaning of the words we can tell that they have something in common:

1) Monochrome: This refers to an artwork, a painting or drawing that has just one color.

2) Monocot: This is a type of flowering plant that has a single embryo and a single cotyledon.

3) Monosaccharide: This is a type of simple sugar that contains one sugar unit that cannot be split.

4) Monounsaturated: This refers to a molecule that contains one double or triple bond.

5) Monoxide: This refers to a form of oxide that contains only one oxygen atom.

From the definitions above, all the words mean having only one or a single item.

That is what they have in common.

Calcium and sulfur Enter the ions formed by these elements and separate your answers with a comma (e.G., Sr2+,As3−).

Answers

Answer:

Explanation:

Calcium (Ca) is a metallic element and belongs to group II of the Periodic Table. So, it can lose 2 electrons to form the positively charged ion Ca²⁺.

Sulfur (S) is a non-metal element, so it has the tendency to gain electrons and to form anions. It accepts two electrons to form the sulfide ion S²⁻.

Mr Singh is cooking using wo pans of oiling water. Both pans are made of steel, but one pan has a much thicker base than the other pan. Explain how energy is transferred through the metal pans. Write about particles in your answer.

Answers

Answer:

See explanation

Explanation:

When either pan is heated, energy is transferred via conduction. Conduction is the process by which heat is transferred through a material, the average position of the particles remaining the same.

When the pans are heated, the particles in each pan vibrate faster and transfer this energy rapidly to neighboring particles.

The pan with a thicker base has more particles in it than the pan with lighter weight base. Note that, The rate of heat transfer is inversely proportional to the thickness of the material in question. Hence, the thicker the base, the more the number of particles present and the longer the time it takes for the food to cook.
