Which of the following could result from the fission of carbon?

1 answer:

3 0

In nuclear reactions, there are can be two kinds: nuclear fission and nuclear fusion. From the word itself, fusion is combination while fission is breaking. Nuclear reactions are different from chemical reactions. Whereas chemical reactions from compounds by exchanging elements, nuclear reactions add or eliminate subparticles, like protons, neutrons and electrons.

So, when carbon is split up, their protons should add up to 6, which is its atomic number. From the choices, the only obvious answer is two lithium atoms. To investigate further, lithium has an atomic number of 3. So, two lithium atoms would equal to 6.

Therefore, the answer is two lithium atoms.

Suppose Gabor, a scuba diver, is at a depth of 15m15m. Assume that: The air pressure in his air tract is the same as the net wat

alexandr1967 [171]

Answer:

The ration of molar concentration is "2.5".

Explanation:

The given values are:

Average density of salt water,

= $1.03 \ g/cm^3$

Net pressure,

= $2.00 \ atm$

Increase in pressure,

= $1.00 \ atm$

Now,

The under water pressure will be:

= $\frac{15 \ m}{10}\times 1 \ atm +1 \ atm$

= $1.5\times 1+1$

= $1.5+1$

= $2.5 \ atm$

hence,

The ratio will be:

= $\frac{(\frac{n}{V})_{15m} }{(\frac{n}{V})_{surface} }$

or,

= $\frac{P}{P_s}$

= $\frac{2.5}{1}$

= $2.5$

This type of pure substance contains more than one type of element chemically bonded

Alex787 [66]

Answer:

A. Compounds

Explanation:

Firstly, don't let the word "pure" confuse you; this is pretty much irrelevant to the question.

The key to answering this question lies in "substance" and "more than one type of element chemically bonded."

Something you ought to memorize is that a substance is either an element or compound. Therefore, you can eliminate choices B./C.

Next, use the part of the definition that says "more than one type of element chemically bonded" to conclude that it's a compound. Not only is this the definition of a compound, but the fact that is says more than one type of element should automatically tell you that it is different from just a regular element (Choice D.).

A water bath in a physical chemistry lab is 1.85m long, 0.810m wide and 0.740m deep. If it is filled to within 2.57 in from the

jenyasd209 [6]

Answer:

The volume of water in water bath is 1,011 Liters.

Explanation:

Length of the water bath, L = 1.85 m

Width of the water bath, W= 0.810 m

Height of the water bath ,H= 0.740 m

Height of the water in water bath, h= 0.740 m - 2.57 inches

1 m = 39.37 inch
