Answer:

0.9 moles of water

Explanation:

Use mole ratios:

5 : 6

divide by 5 on both sides

1 : 1.2

multiply by 0.75 on both sides

0.75 : 0.9

So the result is 0.9 moles of water

(Please correct me if I'm wrong)

Calculate the volume of hydrogen if you have 12.1 moles of Hydrogen.
vodomira [7]

To Find :

The volume of 12.1 moles hydrogen at STP.

Solution :

We know at STP, 1 mole of gas any gas occupy a volume of 22.4 L.

Let, volume of 12.1 moles of hydrogen is x.

So, x = 22.4 × 12.1 L

x = 271.04 L

Therefore, the volume of hydrogen gas at STP is 271.04 L.

how to determine the aspects for core and valence electrons in a periodic table. How comes in some elements like cobalt the 3d i
dusya [7]

Answer:

See explanation

Explanation:

The electron configuration of an atom in an element determines the property of the atom. The core electrons are found inside the atom while the valence electrons are found on the outermost shell of the atom.

For cobalt, the outermost shell electron configuration is; [Ar] 3d7 4s2. The 3d7 and 4s2 are found in the valence shell of cobalt.

For arsenic, the electronic configuration is [Ar] 3d¹⁰ 4s² 4p³. The valence electrons are 4s2, 4p3. The 3d electrons are found inside the arsenic atom.

O₂(g) as a reactant

<h3>Further explanation</h3>

In chemical reactions, there is a reaction between reagents and products

Reaction:

aA + bB ⇒ cC

Substances A and B are called a reactants

Substance C is called a product

In the above reaction:

  • Reactants: C, O₂ and CO
  • Products: CO and CO₂

CO functions as a product in the first reaction and functions as a reactant in the second reaction  

In the final chemical equation :

CO(g)+30₂(g) → CO₂(g)

O₂ is on the left so it is called the reactant
