Answer:

A. write balanced chemical equation (including states), for this process.

Explanation:

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

Hydrocarbon combustions always involve

[some hydrocarbon] + oxygen --> carbon dioxide + steam.

C6H6(l) + O2 (g)--> CO2 (g)+ H2O (g)

Balance carbon, six on each side:

C6H6(l) + O2 (g)--> 6CO2 (g)+ H2O (g)

Balance hydrogen, six on each side:

C6H6(l) + O2 (g)--> 6CO2(g) + 3H2O (g)

Now, we have fifteen oxygens on the right and O2 on the left.

Two ways to deal with that. We can use a fraction:

C6H6 (l)+ (15/2)O2 (g)--> 6CO2 (g)+ 3H2O (g)

Or, if you prefer to have whole number coefficients, double everything

to get rid of the fraction:

2C6H6 (l)+ 15O2 (g)--> 12CO2 (g)+ 6H2O (g)

With the SATP states thrown in...

C6H6(l) + (15/2)O2(g) --> 6CO2(g) + 3H2O(g)

Is there are a total of 7.3 x 10^29 atoms in a sample of glucose, C6H12O6(s),what amount in miles of glucose is in the sample?

Vadim26 [7]

(7.3 x 10^29 atoms) / (24 atoms/molecule) / (6.022 x 10^23 molecules/mol) =

5.1 x 10^4 mol C6H12O6

Why are halogens reactive?

erica [24]

<u>Halogens are reactive because:</u>

They have high electronegativity and also high nuclear charge. So, they are reactive and also gain an electron when they react with other elements.

Since they are very reactive, halogens are very harmful to living organisms. Some of the halogens are fluorine, chlorine, bromine, iodine, astatine. These are mostly non metals. Fluorine is one of the most reactive gas and also very toxic gas. When Fluorine reacts with glass along with small amounts of water, it forms silicon tetra fluoride (SiF4). Hence fluorine should be handled with substances like the inert organofluorine compound Teflon.

Develop a product by using principles of science to encounter environment related problems

Oxana [17]

It is because we are, this is the first time in human history, where we have technology and science is widely accepted, without being ridiculed by religious figures.
Science can provide us with enough detailed knowledge about nature to solve and prevent environmental problems. ... It is possible to prevent pollution in the future and develop 'clean' industrial processes that have no environmental impacts.
Develop a product by using principles of science to encounter environment related problems
It is currently believed that science and technology can provide effective solutions to most, if not all, environmental problems facing western industrial societies. ... It can therefore be concluded that science and technology have only very limited potential in solving current and future environmental problems.
Ways Technology is Helping the Environment
We use Less Energy to do Things.
Energy Production is Becoming Cleaner.
Clean Energy Systems are More Effective.
Food Production is Becoming More Eco-friendly
Recycling is Reducing Waste and Pollution.
Cities are Becoming Less Polluted
We Are Becoming More Aware Of Our Effect On The Planet
We Can Share More Knowledge And Understanding

What type of bond would be formed between hypothetical elements X and Y in the the compound XY based on their electronegativity

Mnenie [13.5K]

The bond is polar covalent because the difference in electronegativity is greater than 0.4, but less than 1.7.

Electronegativity refers to the ability of an atom in a compound to attract the electrons of the bond towards itself. It is a periodic trend that increases across the period but decreases down the group.

The electronegativity difference between the two atoms as shown in the question is 1.55. This means that the bond is polar covalent because the difference in electronegativity is greater than 0.4, but less than 1.7.
