Answer:

Explanation:

In a chemical formula, the oxidation state of transition metals can be determined by establishing the relationships between the electrons gained and that which is lost by an atom.

We know that for compounds to be formed, atoms would either lose, gain or share electrons between one another.

The oxidation state is usually expressed using the oxidation number and it is a formal charge assigned to an atom which is present in a molecule or ion.

To ascertain the oxidation state, we have to comply with some rules:

The algebraic sum of all oxidation numbers of an atom in a neutral compound is zero.
The algebraic sum of all the oxidation numbers of all atoms in an ion containing more than one kind of atom is equal to the charge on the ion.

For example, let us find the oxidation state of Cr in Cr₂O₇²⁻

This would be: 2x + 7(-2) = -2

x = +6

We see that the oxidation number of Cr, a transition metal in the given ion is +6.

Answer:

Scenario B

Explanation:

In Scenario B; Yuki reads an article in the Professional Journal of Medicine stating that ginger root can help prevent some types of cancer. The article was published in a professional journal. Manuscripts sent to professional journals for publication must pass through a peer review process in order to ascertain the reliability of the data presented.

Magazine articles may not go through a peer review process since it is not written for the consumption of a professional audience.

What is the [OH-] in a solution that has a [H3O+] = 1.0 x 10-6 M?

nika2105 [10]

Answer:

explanation

$kw = 1 \times {10}^{ - 14}$

$oh = {?}$

$h3o = 1.0 \times 10 {}^{ - 6}$

formula

$kw = h3o \times oh$

$insert \: values$

$1.0 \times 10 {}^{ - 14} = 1.0 \times {10}^{ - 6} \times oh$

$\frac{1.0 \times 10 {}^{ - 14} }{ 1.0 \times 10 {}^{ - 6} } = oh$

$1 \times {10}^{ - 8}$

Rank the following substances in order from most soluble in water to least soluble in water: methane, CH4; 2-butanol, C4H9OH; ma

Taya2010 [7]

Answer: The given substances are placed in order from most soluble in water to least soluble in water as follows.

$MgCl_{2}$ > $C_{4}H_{9}OH$ > $C_{3}H_{8}$ > $CH_{4}$

Explanation:

It is known that like dissolves like which means a polar compound will be soluble in a polar solvent. And, a non-polar compound will be soluble in non-polar solvent.

Ionic compounds are soluble in polar solvent like water. For example, $MgCl_{2}$ is an ionic compound and it is readily soluble in water.

2-butanol ( $C_{4}H_{9}OH$ ) is also a polar compound and it will also dissolve in water but to a lesser extent as compared to magnesium chloride.

Whereas both methane and propane are non-polar in nature. But as propane is larger in size as compared to methane so, it will be slightly more soluble in water as compared to methane.

Thus, we can conclude that the given substances are placed in order from most soluble in water to least soluble in water as follows.

$MgCl_{2}$ > $C_{4}H_{9}OH$ > $C_{3}H_{8}$ > $CH_{4}$
