Answer:

It tells how quickly products will be made.

Explanation:

ap3

x

The reaction rate provides information about how quickly products will be made in a chemical reaction.

The reaction rate is a measure of how fast a chemical reaction proceeds over time. It provides information about the speed at which reactants are consumed and products are formed during a reaction. The reaction rate is typically expressed as the change in concentration of a reactant or product per unit of time.

The reaction rate is influenced by various factors such as the nature of the reactants, concentration of reactants, temperature, surface area, and the presence of catalysts. By measuring the reaction rate, scientists can gain insights into the kinetics of a reaction and understand the factors that affect its speed.

The reaction rate is particularly important because it allows us to predict and control the rate at which products are formed. It is useful in various applications, including industrial processes, pharmaceutical development, and environmental studies. By manipulating the reaction conditions, such as adjusting the concentration of reactants or introducing a catalyst, we can alter the reaction rate to achieve desired outcomes.

In summary, the reaction rate provides valuable information about the speed at which products are formed in a chemical reaction, allowing us to understand and control the kinetics of the process.

.The cell membrane acts like a filter allowing necessary materials in and waste out, while keeping the organelles and cytoplasm in. This means that a cell membrane is selectively

Answers

Answer: Permeable

Explanation:

The cell membrane is the outermost covering around the animal cells but it is also surrounded by the cell wall in the case of the plant cells. The cell membrane plays an important role in the cell that is it allows the entry of only certain substances like ions, molecules, atoms within the cell and only allows the exist of certain substances out of the cell. This is the selective permeability of the membrane. This process occurs through osmosis in which the desired molecules move from higher to lower concentration. Also it helps in maintaining the balance of nutrients and water within the cell. This helps in getting rid of the waste outside the cell. It provides the protection to the organelles and cytoplasm in the cell against the external injury caused by the external stressor outside the cell like water, pressure, pathogen, and others.

Explanation:

P₄o₁₀(g) + 6H₂O(l) => 4H₃PO₄(aq) + 424Kj

moles H₃PO₄ = (944.3g H₃PO₄) /(97.994g H₃PO₄ /mole  H₃PO₄)

From equation reaction ratios ...

4 moles H₃PO₄ => 424 Kj

4 moles H₃PO₄/9.64 moles H₃PO₄ = (424Kj)/(?)

How many milliliters of 0.100 M HClO4 solution are needed to neutralize 50.00 mL of 0.0832 M NaOH?

Answers

HClO4 +NaOH -----> NaClO4 + H2O
moles of NaOH = (0.0832 x 50 ) /1000= 4.16 x10^-3 moles
since the mole ratio of HClO4 to NaOH is 1:1 the moles of HClO4 is also 4.16 x 10^-3 moles

volume of HClO4 is therefore = moles/ molarity
that is 4.16 x 10^-3mol/ 0.167 mol/L= 0.0249L
multiply by 1000 to convert to ml
0.0249 x 1000= 24.9 ml

The milliliters of 0.100 M HClO4 solution are needed to neutralize 50.00 mL of 0.0832 M NaOH is 24.9 ml.

What is neutralization?

Neutralization is defined as a chemical reaction in which an acid and a base quantitatively react with one another. Because it determines how acidic or basic a solution is, a solution's pH is crucial. The interaction of H+ ions and OH- ions produces water in a neutralization reaction, which occurs when an acid and a base react to form water and a salt.

Since the mole ratio of HClO4 to NaOH is 1:1, the moles of HClO4 are equal to 4.16 x 10-3 moles.

The moles of NaOH are equal to (0.0832 x 50) /1000.

Therefore, the volume of HClO4 is equal to the moles/molarity, which is 4.16 x 10-3mol/ 0.167 mol/L= 0.0249L.

This amount is then multiplied by 1000 to get ml: 0.0249 x 1000 = 24.9 ml.

Thus, the milliliters of 0.100 M HClO4 solution are needed to neutralize 50.00 mL of 0.0832 M NaOH is 24.9 ml.

Answers

Answer:

Sound waves travel faster in a liquid than a gas, our ears are just not designed to  translate the faster moving waves.

Explanation:

Sound waves are mechanical waves which travel through vibrating the medium (the "stuff") they're traveling through. This means they actually move faster through materials that are more dense, and will move more quickly through liquid than gas, and a solid than a liquid. However, our ears are adapted to "translating" sound waves in air rather than water, so we don't understand the music well when the waves move through the water.

A similar idea explains why our vision is blurry underwater; light waves travel at a different speed (slower, not faster!) in water and our eyes perceive this change in speed as blurriness.

A mixture of four gases exerts a total pressure of 960
mm Hg. Gase A each exert 120 mm Hg. Gas B exerts
50 mm Hg. What pressure is exerted by gas C?

Answers

Omitted question:I think you mean Gas A and D each exert 120 mm Hg, if Gas D has a different value , just lug it into he equation as shown below and solve.

Answer:Gas C= 670mmHg

Explanation:

According to Dalton law of partial pressure

The total pressure of a mixture of gases is the sum of the pressures of each gas and can be illustrated as

Pressure total=P1+P2+… +Pn.

Total Pressure = Gas A + Gas B + Gas C + Gas D + Gas...

Now we have

Total Pressure = 120 mm Hg + 50mm Hg + Gas C + 120 mm Hg

960mmHg = 120 mm Hg + 50mm Hg + Gas C + 120 mm Hg

960mmHg =290mmHg +Gas C

Gas C =960mmHg -290mmHg

Gas C= 670mmHg

If you add salt to water, its boiling point increases.

When calcium chloride is added to a sample of water, the boiling point will increase. Option A is correct.

What is boiling point?

The boiling point of the liquid is the temperature at which the vapor pressure of a given liquid equals the external pressure or atmospheric pressure surrounding the given liquid.

The calcium chloride is added to a sample of water it releases the some amount heat and become exothermic and the boiling point will increase due to the reaction of water and calcium chloride.

3.) 2.46 grams of Cu(NO3)2 would contain how many formula units?

Answers

Answer:

7.90×10²¹ formula units

Explanation:

From the question given above, the following data were obtained:

Mass of Cu(NO₃)₂ = 2.46 g

Formula units of Cu(NO₃)₂ =?

From Avogadro's hypothesis,

1 mole of Cu(NO₃)₂ = 6.02×10²³ formula units

Next, we shall determine the mass of 1 mole of Cu(NO₃)₂. This can be obtained as follow:

1 mole of Cu(NO₃)₂ = 63.5 + 2[14 + (3×16)]

= 63.5 + 2[14 + 48]

= 63.5 + 2[62]

= 63.5 + 124

= 187.5 g

Thus,

187.5 g of Cu(NO₃)₂ = 6.02×10²³ formula units

Finally, we shall determine the formula units contained in 2.46 g of Cu(NO₃)₂. This can be obtained as follow:

187.5 g of Cu(NO₃)₂ = 6.02×10²³ formula units.

Therefore,

2.46 g of Cu(NO₃)₂ =

(2.46 × 6.02×10²³)/187.5

= 7.90×10²¹ formula units

Thus, 2.46 g of Cu(NO₃)₂ contains 7.90×10²¹ formula units
