Answer:

ll matter is composed of extremely small particles called atoms.

Atoms of a given element are identical in size, mass, and other properties. Atoms of different elements differ in size, mass, and other properties.

Atoms cannot be subdivided, created, or destroyed.

Atoms of different elements can combine in simple whole number ratios to form chemical compounds.

In chemical reactions, atoms are combined, separated, or rearranged.

Each atom is uniform, homogeneous, colorless, tasteless, and indivisible.ll atoms of a given element are identical in mass and properties. Compounds are formed by a combination of two or more different kinds of atoms. A chemical reaction is a rearrangement of atom.

Sergio [31]

Answer:

See explanation

Explanation:

The third and fourth elements in the first transition series are vanadium and chromium. They contain 23 and 24 electrons respectively.

In universe L, the electron configuration of vanadium is;

[X] 3d3 4s2

In universe L, the electron configuration of chromium is;

[X] 3d4 4s2

The electron configuration of chromium has to change since there are four instead of five d orbitals in universe L.

What is the pOH of 0.50 molar H3BO3?

Crazy boy [7]

Answer:

A. 10.25

Explanation:

Pkb =4.77

So pka = 14 - pka = 9.23

$Ka =10^{-pka}$

$H_3 BO_3 (aq)+ H_2 O(l) H_2 BO_3^- (aq)+H_3 O^+ (aq)$

Initial 0.50M 0 0

Change -x +x +x

Equilibrium 0.50M-x +x +x

$Ka =\frac {((x)(x))}{(0.50M-x)}$

$5.88\times10^{-10}= \frac {x^2}{(0.50M-x)}$

(-x is neglected) so we get

$5.88\times10^{-10}\times0.50=x^2\\\\x^2=2.94\times10^{-10}$

$x=\sqrt{x^2}=1.72\times10^{-5} M=H^3 O^{+}$

$pH=-log[H^3 O^+]\\\\pH=-log[1.72\times10^{-5}]\\\\pH=4.76$

pOH = 14 - pH

= 14 - 4.76

pOH = 9.24 is the answer

Option A - 10.25 is the answer which is close to 9.24

A sample of gold has a mass of 96.5 g and a volume of 5.00 cm3. What is the density of gold in g/cm3

viva [34]

Answer: The density would be p = 19.3 g/cm3 because

Explanation: because if you calculate density the formula would be d = m

so just use the values giving and you get the answer by plugging the 96.5 mass then 5 for the volume then divide it.
