Element 6 has the lowest ionization energy

Answer:

Element 6 has the lowest ionization energy

Explanation:

The ionization energy increases across the period but decreases down the group of a periodic table.

Which implies that the elements with the lowest ionization energies would be in the bottom left-hand corner of the periodic table. The change in ionization energies is also increases going down the periodic table (by change within a group) than going across the periodic table (by change within a period). From the 3 elements above we could infer that element 6 has the lowest ionization energy.

Calculate the density of a solid in g/cm3 if it weighs 38.3 kg and has a volume of 0.00463 m3.

RideAnS [48]

Answer: D=8.27 g/cm³

Explanation:

Density is mass/volume. Mass is in grams and volume is in liters. In this case, the problem wants our volume to be in cm³. All we need to do is to make some conversions to convert kg/m³ to g/cm³.

$D=\frac{38.3kg}{0.00463m^3} *\frac{(1m)^3}{(100cm)^3} *\frac{1000g}{1kg}$

With this equation, the m³ and kg cancel out, and we are left with g/cm³.

D=8.27 g/cm³

A chemist dissolves silver nitrate (AgNO₃) in water. He also dissolves ammonium chloride (NH₄Cl) in water. He mixes the two solu

Leviafan [203]

Answer: $AgNO_3(aq)+NH_4Cl(aq)\rightarrow AgCl(s)+NH_4NO_3(aq)$

Explanation:

A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas.

The balanced chemical equation for reaction of silver nitrate in water.and ammonium chloride in water to give precipitate of silver chloride :

$AgNO_3(aq)+NH_4Cl(aq)\rightarrow AgCl(s)+NH_4NO_3(aq)$

How do you write a polynomial in standard form?

olchik [2.2K]

<span>One way to write a polynomial is in standard form. In order to write any polynomial in standard form, you look at the degree of each term. You then write each term in order of degree, from highest to lowest, left to write. First, look at the degrees for each term in the expression.</span> and in this way you will be able to write polynominal in standard form.
