Answer:

Check the explanation

Explanation:

Lets start by drawing the ICE chart

reaction is

...............CO + H2O ========= CO2 + H2

I.............2.6.........3.4..........................0................0

E...........1.88........2.68......................0.72............0.72

since reaction is 1 : 1 if 0.72 atm of H2 are produced then the same amount of CO2 will be formed

calculate Kp this is the relationship between the pressure of products and the pressure of reactants

Kp = Pproducts / Preactants = [Pco2* PH2] / [PCO * PH2O]

Kp = 0.72 * 0.72 / (1.88 * 2.68) = 0.1029

Write the ICE chart again

...............CO + H2O ========= CO2 + H2

I.............1.88.........2.68+1.1.................0.72................0.72

C...........-x............. -x..............................+x........................+x

E......1.88 - x...........3.78-x.....................0.72+x..... ..0.72+x

Kp is = (0.72+x)*(0.72+x) /[ (1.88-x)*(3.78-x) ] = 0.1029

lets say that x is the change of pressure.

If you solve this equation you will get a value of x equal to 0.1

Pressure of CO2 is

0.72 + 0.1= 0.82 atm

using 2 sig figures this would be

8.2x10-1 atm

A material has an ASTM grain size number of 7. Determine the magnification, if the number of grains per square inch observed is:

Luden [163]

Answer:

A) M = 100X

B) M = 36X

C) M = 178.88X

Explanation:

Given data:

ASTM grain size number 7

a) total grain per inch^2 - 64 grain/inch^2

we know that number of grain per square inch is given as

$Nm = 2^{n-1} (\frac{100}{M})^2$

where M is magnification, n is grain size

therefore we have

$64 = 2^{7-1}(\frac{100}{M})^2$

solving for M we get

M = 100 X

B) total grain per inch^2 = 500 grain/inch^2

we know that number of grain per square inch is given as

$Nm = 2^{n-1} (\frac{100}{M})^2$

where M is magnification, n is grain size

therefore we have $500 = 2^{7-1}(\frac{100}{M})^2$

solving for M we get

M = 36 X

C) Total grain per inch^2 = 20 grain/inch^2

we know that number of grain per square inch is given as

$Nm = 2^{n-1} (\frac{100}{M})^2$

where M is magnification, n is grain size

therefore we have $20 = 2^{7-1}(\frac{100}{M})^2$

solving for M we get

M = 178.88 X

Name the following covalent compound:

mote1985 [20]

Answer:

Pentasulfur nonanitride.

Explanation:

In order to name a compound properly, we need to identify the type of a compound we have. The given compound consists of two non-metals, sulfur and nitrogen. This implies that we have a covalent compound in contrast to an ionic compound which consists of a metal and a non-metal.

To name a molecular/covalent compound, we should use prefixes stating the number of atoms we have. In this case, we have 5 sulfur atoms. The prefix for 5 is 'penta'. That said, we have 'pentasulfur' as our beginning of the name.

We also have 9 nitrogen atoms. The second atom in the molecular formula would have an ending of '-ide', so we expect to have 'nitride'. Adding a prefix for 9, we'd have 'nonanitride'.

Putting everything together, the name is pentasulfur nonanitride.

Some common prefixes:

mono – one (we don't state mono for the first atom, e. g., we would name CO as carbon monoxide instead of monocarbon monoxide);

di – two;

tri – three;

tetra – four;

penta – five;

hexa – six;

hepta – seven;

octa – eight;

nona – nine;

deca – ten.

Notice that 'decanitride' would be correct in case you had 10 nitrogen atoms, similarly, tetra and hexa stand for 4 and 6 instead of 5 given sulfur atoms.

Hey there!

Static electricity is a missing charge. When positive ions are formed (where an electron is missing), this imbalance is called static electricity.
