Answer: D

Explanation: The engine cycle begins with the intake stroke as the piston is pulled towards the crankshaft (to the left in the figure). The intake valve is open, and fuel and air are drawn past the valve and into the combustion chamber and cylinder from the intake manifold located on top of the combustion chamber.

Which chemical is the reducing agent in the redox reaction below?

posledela

Option (a) is correct.

A reducing agent is the one which loses electrons to other substance.

Here, Zn has oxidation number 0 in the L.H.S of the equation, but on R.H.S its oxidation number is +2 i.e. it Zn has donated two of its electrons to $Fe^{2+}$ .

Hence, Zn is the reducing agent here.

If the gram-formula mass of substance X is 180 g/mol, determine the molarity of the solution at Point E

Alina [70]

<h3><u>Answer;</u></h3>

<u>= 5 M or 5 moles/liter</u>

<h3><u>Explanation;</u></h3>

At point E, 90 g of substances X are dissolved in 100 g of the solvent.

100g of the solvent is equal to 100 ml

Molarity is the number of moles of a substance in one liter of a solvent.

90 g of X are in 100 ml

But; the RFM of X = 180 g/l

Therefore; the moles of X in 90 g = 90/180

= 0.5 moles

Therefore;

0.5 moles of X are contained in 100 ml of the solvent;

Thus, molarity = 0.5 × 1000/100

=<u> 5 M or 5 moles/liter</u>

miv72 [106K]

1 kpa = 7.5 mm of Hg [Remember it or can be found on internet ]

So, 275 kpa = 7.5 x 275 = 2062.5 mm of Hg
