The gallionella bacteria  reaction

that is Fe2+ →  Fe3+ is example of  oxidation reaction (answer A)

Explanation

oxidation reaction reaction occurs when electrons are lost during reaction by a molecule or ion or atom. when oxidation occurs  the oxidation state of the molecule or ion or atom increases. For this reason Fe2+ → Fe3+ is a oxidation reaction since the oxidation state move from oxidation state 2 to 3

Describe how you would prepare 350 ml of 0.100 m c12h22o11 starting with 3.00l of 1.50 m c12h22o11
Leona [35]

To prepare 350 mL of 0.100 M solution from a 1.50 M solution, we simply have to use the formula:

M1 V1 = M2 V2

So from the formula, we will know how much volume of the 1.50 M we actually need.

 

1.50 M * V1 = 0.100 M * 350 mL

V1 = 23.33 mL

 

So we need 23.33 mL of the 1.50 M solution. We dilute it with water to a volume of 350 mL. So water needed is:

350 mL – 23.33 mL = 326.67 mL water

 

 

Steps:

1. Take 23.33 mL of 1.50 M solution

<span>2. Add 326.67 mL of water to make 350 mL of 0.100 M solution</span>

An element's atomic number is 68. How many protons would an atom of this element have?
Evgen [1.6K]
Answer: 68.

Explanation:

The atomic number is the number that idenfities an element.

The atomic number is the number of protons of an element.

Every element has a different number of protons.

The elements are arranged in the periodic table as per their atomic number (number of protons).

The first element is hydrogen (H), its atomic number is 1, and it has 1 proton.

The second element is helium (He), its atomic number is 2 (it has 2 protons)-

Those two elements form the first period (row) of the periodic table.

The second row (period) has the elements Li, Be, B, C, N, O, F and Ne, whose respective atomic numbers (number of protons are) 3, 4, 5, 6, 7, 8, 9, and 10, respectively.

And so, you may idenfity each of the 118 elements known, with a different atomic number (number of protons).
