C6H12O6 -------> 6 C + 6 H20moles C6H12O6 = ( 1745 g ) / ( 180 g/mol ) = 96.94 mol C6H12O6mol C produced = ( 96.94 mol C6H12O6 reacted ) ( 6 mol C made / mol C6H12O6 reacted )mol C produced = 58.17 moles C produced <-----------------------Hope I Helped You!!! :-)Have A Good Day!!!

What are four physical properties of aluminum foil?

Answers

1) solid
2) ductile
3) malleable
4) silver in color

Malleable means that it is "flexible" or can be permanently reshaped easily. Ductile means that it can be drawn out into a wire. Aluminum foil's state of matter is solid, and it appears in a silver color.

Which has the longest bond length for the Cl-O bond?1. ClO4-
2. ClO3-
3. ClO2-
4. ClO-

Answers

Answer:

4 ClO-

Explanation:

Bond length ∝ 1/ Bond order

Bond order of ClO − =1,

Bond order of ClO 2− =1.5,

Bond order of ClO 3− =1.66 ,

Bond order of ClO 4− =1.75.

Thus the order of bond length is

ClO 4− <ClO3− <ClO2−

<ClO −

Of the elements Na, C, Si, and P, which is a metal?a. Na
b. C
c. Si
d. P

Answers

Answer: Option (a) is the correct answer.

Explanation:

A metal is a substance which loses electron(s) in order to attain stability.

For example, sodium is an alkali metals with atomic number 11 and its electronic distribution is 2, 8, 1.

So, in order to attain stability sodium will readily lose 1 electron and forms $Na^(+)$ ion.

Whereas non-metals are the substances which gain electron(s) in order to attain stability.

For example, atomic number of carbon is 6 and its electronic configuration is 2, 4.

To attain stability a carbon atom shares it 4 valence electrons with another atom.

Thus, we can conclude that out of the given options, Na is a metal.

a. Na - Sodium

Sodium is an alkali metal in Group 1A of the periodic table. Metals are found in groups 1A, 2A, and 3A, along with the transition and inner transition metals.

Which statement correctly compares an atom of an alkali metal with an atom of the alkaline earth metal next to it on the periodic table?

Answers

The atom of alkaline earth metal has one more proton and one more electron than the alkali metal that is next to it to the left on the periodic table. Then the atomic number of the alkali metal is one unit less than the atomic number of the alkaline earth metal next to it.

Calculate the volume of each of the following gases at STP 7.6 mol Ar 0.44 mol C2,H3

Answers

For Ar :

1 mol ------------ 22.4 L ( at STP )
7.6 mol ---------- x L

x = 7.6 * 22.4

x = 170.24 L
-----------------------------------------------------------------
For C2H3:

1 mol ------------ 22.4 ( at STP)
0.44 mol --------- y L

y = 0.44 * 22.4

y = 9.856 L

hope this helps !.

The volume of 0.44 moles of ethylene gas at STP is approximately 10.33 liters.

To calculate the volume of gases at Standard Temperature and Pressure (STP), we can use the ideal gas law:

PV = nRT

Where:

P = Pressure (at STP, it's 1 atmosphere, or 1 atm)

V = Volume (in liters)

n = Number of moles

R = Ideal gas constant (0.0821 L·atm/mol·K)

T = Temperature (at STP, it's 273.15 K)

Let's calculate the volume for each gas:

For 7.6 moles of Ar (argon):

P = 1 atm

n = 7.6 moles

R = 0.0821 L·atm/mol·K

T = 273.15 K

Now, plug these values into the ideal gas law:

V = (nRT) / P

V = (7.6 moles * 0.0821 L·atm/mol·K * 273.15 K) / 1 atm

V ≈ 172.75 liters

So, the volume of 7.6 moles of argon gas at STP is approximately 172.75 liters.

For 0.44 moles of C2H3 (ethylene):

P = 1 atm

n = 0.44 moles

R = 0.0821 L·atm/mol·K

T = 273.15 K

Now, plug these values into the ideal gas law:

V = (nRT) / P

V = (0.44 moles * 0.0821 L·atm/mol·K * 273.15 K) / 1 atm

V ≈ 10.33 liters
