It is empirical formula

<span><span>C3</span><span>H2</span>N</span> tells you the lowest possible whole number ratio of atoms in that molecule. That EMPIRICAL FORMULA must have the same ratio as the actual, MOLECULAR FORMULA. The empirical mass and molecular mass must share the same ratio as the formulas do, so find the mass of <span><span>C3</span><span>H2</span>N</span>: <span>3(12g)+2(1g)+14g=52g</span> and compare that to the molecular weight of 260g. <span><span><span>MF</span><span>EF</span></span>=<span><span>MW</span><span>EW</span></span></span>so<span><span><span>MF</span><span>EF</span></span>=<span><span>260g</span><span>52g</span></span>=5</span><span>the actual formula is five times heavier than the empirical formula, so take the empirical formula and multiply each subscript by 5. That's why it works</span>

How can exposoure to high energy waves be both harmful and helpful to cells??
belka [17]
Exposure to high energy waves can be helpful to cells by damaging DNA in cells, meaning if somebody were to have cancer cells it breaks down the bad cells and it can shrink tumor. It can be harmful by damaging skin cells, which we need as our first line of defense. Meaning, it could cause skin cancer. Hope this helped!

Which element in period 4 has the highest electronegativity
vova2212 [387]

<span>Electronegativity is the property of an element that measures the ability of it to attract and form electron bonds. The trend in the periodic table in terms of electronegativity decreases from right to left and from top to bottom. In the case of period 4, the element with the highest electronegativity is bromine. </span>

Answer the following questions for H2CrO4:
Sholpan [36]

If this molecule is one half of a buffer, then the formula of the second half of the buffer is M2CrO4 where M is a univalent metal.

<h3>What is a strong acid?</h3>

A weak acid is one that is able to ionize completely in solution. The acid called chromic acid H2CrO4 is not  able to ionize completely in solution.

We know that a buffer is composed of a weak acid and its salt or a weak base and its salt hence if the acid H2CrO4 is present in a buffer then the other half must be  salt of the acid.

If this molecule is one half of a buffer, then the formula of the second half of the buffer is M2CrO4 where M is a univalent metal.

Why does electronegativity increase as you move from left to right across
Katen [24]

Answer: increasing number of protons increases the positive charge of the nucleus.

Explanation: because as the electronegativity moves from left to right on the periodic table the protons do increase to make it into a positive charge.
