Answer:

automatic transmission

Explanation:

An automatic transmission (sometimes abbreviated to auto or AT) is a multi-speed transmission used in motor vehicles that does not require any driver input to change gears under normal driving conditions.

Answer:

ionic bonds in the solute are broken and new ion-dipose forces in the solution are formed

Explanation:

HCI + NaOH --> NaCl + H2O

Neutralization reaction is the reaction between acid and base which results in formation of salt and water. Here salt is NaCl (common salt) in above reaction.

SO, (A) H20 + NaCl is your answer.

Answer:

There is too much here for me to attempt in one sitting, but I will get you started and give suggestions that may help you proceed on your own.

a)  As far as I can tell, you didn't provide the reduction potentials in the table below.  So, I looked them up and find them to be

Cu2+ +2e- ==> Cu(s)  Eº = +0.34 V

Zn2+ + 2e- ==> Zn(s)  Eº = -0.76 V

Net ionic equation:  Cu2+(aq) + Zn(s) ==> Cu(s) + Zn2+(aq)

b)  Eºcell = 0.34 V + 0.76 V = 1.10 V

c)  ∆Gº = -nFEº  where n = number of electrons transferred (2) and F = 96,485 C/mol e- and Eº = 1.1 V

d)  Again, there is no diagram

e)  same

f)  Use the Nernst equation  Ecell = Eºcell - 2.303RT/nF log Q  where R = 8.314; T = Kelvin; F = Faraday const. and Q = reaction quotient, i.e. products/reactants

g)  the cell voltage is an intensive property.  That should help you answer this part of the question

Answer:

1.3 atm

Explanation:

Apply the ideal gas law: PV = nRT

Since we need to find the pressure, solve for pressure:

P = nRT / V

Plug in our given values of n = 4.6 moles, R = 0.08206 (ideal gas law constant using atm), T = 325 K, and V = 96.8 L:

P = 4.6(0.08206)(325) / 96.8 = 1.267 atm -> 1.3 atm (two significant figures)

Answer:

22.45g of Fe will be produced

Explanation:

The balanced reaction is:

Fe₂O₃(s) + 3CO(g) → 2Fe(s) + 3CO₂(g)

Where 1 mole of Iron (III) oxide reacts with 2 moles of Iron

To solve this question we have to find the moles of iron (III) oxide. With these moles and the balanced reaction we can find the moles of iron produced and its mass:

Moles iron (III) oxide -Molar mass: 159.69g/mol-

32.1g Fe₂O₃ * (1mol / 159.69g) = 0.201 moles Fe₂O₃

Moles Iron:

0.201 moles Fe₂O₃ * (2mol Fe / 1mol Fe₂O₃) = 0.402 moles of Fe

Mass Fe -Molar mass: 55.845g/mol-

0.402 moles of Fe * (55.845g/mol) =

Answer:

587.5 L (Option A)

Explanation:

The reaction is:

2 C₈H₁₈ + 25O₂  → 16CO₂  + 18H₂O

We know that in STP conditions 1 mol of any gas is contained in 22.4L

Then, we can make a rule of three, to determine the moles of produced carbon dioxide.

22.4L is the volume for 1 mol

376 L will be the volume for  (376 . 1) 22.4 = 16.78 moles at STP conditions.

Stoichiometry is 16:25.

16 moles of CO₂ are produce by the reaction of 25 moles of O₂

Then, 16.78 moles of CO₂ were produced by (16.78 . 25) /16 = 26.2 moles.

Now, the rule of three again.

1 mol of oxygen gas is contained at 22.4L, at STP conditions

26.2 moles might be contained at (26.2 . 22.4)/1 = 587.5 L

Answer:

1.8 moles of NaCl must be produced.

Explanation:

Based on the reaction:

HCl + NaOH → NaCl + H2O

1 mol of HCl reacts with 1 mol of NaOH to produce 1mol of NaCl

To solve this question we must find, as first, the limiting reactant:

1.8 moles of HCl will need 1.8 moles of NaOH for a complete reaction (Ratio of reaction 1:1). As there are 3.3 moles of NaOH,

HCl is limiting reactant

When the 1.8 moles of HCl react completely,

1.8 moles of NaCl must be produced because 1 mole of HCl produce 1 mole of NaCl

Answer:

Insects belong to the class Insecta, and arachnids to the class Arachnida; both classes fall under the Arthropoda phylum, along with crustaceans (crabs, lobster and shrimp). All arthropods have an exoskeleton and jointed legs. They have segmented bodies and appendages, which are divided into different segments. Arachnids belong to an even larger group of animals called “arthropods” which also include insects and crustaceans (lobster, crabs, shrimp, and barnacles).

Respiration is the process of exchange of gases between the cell and atmosphere. The path of respiration involves Outside Air⇒  Nose⇒ Lungs⇒ Bloodstream⇒ Cell.

Respiration is the movement of oxygen from the outside environment to the cells and the removal of carbon dioxide from the cells into the outside environment.

Respiration is of two types depending upon the presence of oxygen:

1. Aerobic Respiration: This takes place in the presence of oxygen

2. Anaerobic Respiration: This takes place in the absence of oxygen.

The path of respiration includes inspiration of outside air into the nose, through the nostrils this air is passed on to the lungs. The alveoli is the site of gaseous exchange in the lungs. In the lungs, oxygen is inspired and carbon dioxide is expired.

The oxygen gas which is inspired by the lungs is dissolved in the blood. Oxygen forms a complex with the hemoglobin protein present in the blood. This blood is then circulated to all the cells and tissues of body. Thus, the oxygen is supplied to all the cells and tissues. The path includes Outside Air⇒  Nose⇒ Lungs⇒ Bloodstream⇒ Cell.

Answer:

Explanation:

Turgor pressure is the pressure forced or in other words, exerted onto the cell wall of the plant. It's caused by the movement of water into the cell. This causes the water to rush and burst into the cell, which increases the pressure onto the cell wall. Due to that, cell swells up, which helping the plant to stand upright and straight.
