15.75 moles of oxygen is required for 4.5 mole of ethane.

<h3>What is a Combustion Reaction ?</h3>

The reaction in which a fuel  gets oxidized by an oxidizing agent is called a Combustion Reaction , releasing a large amount of energy is called Combustion Reaction.

It is given in the question that

4.50 mole of ethane undergoes Combustion

2C₂H₆   +  7O₂   ->  4CO₂  +6H₂O

Mole fraction of ethane to oxygen is 2:7

Moles of ethane = 4.5

4.5 /x = 2/7

4.5 * 7 / 2 = x

x = 15.75 moles.

Therefore 15.75 moles of oxygen is required for 4.5 mole of ethane.

If an atom has 35 protons in the nucleus, how many will it have orbiting nucleus
yan [13]
It will have 35 ''electrons'' . Basically the number of protons in the nucleus of an atom is always equal to the number of electrons but its just that protons are positively charged and electrons are negatively charged.  <span />

What limitation is placed on electrons in the bohr model of the atom?
Olegator [25]
I thinking the limitation is that a shifting electron will always move from a more excited states to a less excited state. Electrons could not circle the nucleus because they would lose energy by emitting electromagnetic radiation and spiral into the nucleus. In addition Bohr was not able to explain electrons orbits of large atom w/many electrons.

C16H32O2(aq) --> 16CO2(g) + 16H2O(l) ... said its wrong though? 
<span>This is because you haven't added any oxygen needed for the combustion, so your equation does'nt balance. Also a solution in water [aq] doesn't burn! </span>
<span>Try </span><span>C16H32O2(s) + 23O2(g) --> 16CO2(g) + 16H2O(l)

In three different experiments, the following results were obtained for the reaction
faust18 [17]
From the given observations,
You can see that as the concentration is doubled, half-life is halved.

That is,half-life is inversely proportional to concentration

As t( half-life) ~ 1/a^(n-1)

For this case n = 2,second order reaction.

R = k X a^n

Using the above formula you will get the rate and rate constant.

What is the mass of a steel cylinder that has a density of 75.0 g/mL and a volume of 12 mL?
siniylev [52]
<span>
hey there!:

density = 75.0 g/mL

Volume = 12 mL

mass = ?

Therefore:

D = m / V

75.0 =m / 12

m = 75.0 * 12

m = 900 g

Answer B
