4 0

Answer:

Atomic number=No. of protons=No. of electrons in ground state(unchanged atom)

Atomic number=13=No. of protons

Atomic mass=no. of protons+no. of neutrons=13+14=27

For isotope no. of proton=13(same atomic number but different mass number are isotopes)

no. of electrons=13

no. of neutrons=14+2=16

Explanation:

 <span>You have to use a Newman projection to make sure that the H on C#2 is anti-coplanar with the Br on C#1. (Those are the two things that are going to be eliminated to make the alkene.) 

My Newman projection looks like this when it's in the right configuration: 
Front carbon (C#2) has ethyl group straight up, H down/left, and CH3 down/right 
Back carbon (C#1) has H straight down, Ph up/left, and Br up/right. 

Then when you eliminate the H from C#2 and the Br from C#1, you will have Ph and the ethyl group on the same side of the molecule, and you'll have the remaining H and CH3 on the same side of the molecule. 

This is going to give you (Z)-2-methyl-1-phenyl-1-butene.</span>

Write a balanced chemical equation, including states of matter, for the combustion of gaseous benzene, c6h6.

Almost all hydrocarbon 'burn' reactions involve oxygen; it's by far the most reactive substance in air. 

<span>Hydrocarbon combustions always involve </span>
<span>[some hydrocarbon] + oxygen --> carbon dioxide + steam. </span>

C6H6(l) + O2 (g)--> CO2 (g)+ H2O (g)

<span>Balance carbon, six on each side: </span>
C6H6(l) + O2 (g)--> 6CO2 (g)+ H2O (g)

<span>Balance hydrogen, six on each side: </span>
C6H6(l) + O2 (g)--> 6CO2(g) + 3H2O (g)

<span>Now, we have fifteen oxygens on the right and O2 on the left. </span>
<span>Two ways to deal with that. We can use a fraction: </span>
C6H6 (l)+ (15/2)O2 (g)--> 6CO2 (g)+ 3H2O (g)

<span>Or, if you prefer to have whole number coefficients, double everything </span>
<span>to get rid of the fraction: </span>
2C6H6 (l)+ 15O2 (g)--> 12CO2 (g)+ 6H2O (g)

<span>With the SATP states thrown in... </span>
C6H6(l) + (15/2)O2(g) --> 6CO2(g) + 3H2O(g)

A slice of cheese has a mass of 14 g and a volume of 11 cm3. What is the density of the cheese in units of g/cm3 and g/mL
cluponka [151]

Answer:

Density =1.27g/cm

Explanation:

Density is the mass per volume of a substance.

That is

Density = mass/volume

Given that mass = 14g

Volume  = 11cm³

Therefore

Density = 14/11 g/cm³

Density =1.27g/cm³

I hope this was helpful, please mark as brainliest
