Chemistry
1 answer:
nexus9112 [7]3 years ago
6 0

Explanation:

<em>First</em><em> </em><em>two</em><em> </em><em>pictures</em><em> </em><em>go</em><em> </em><em>together</em>

From top to bottom, <em>ionisation energy</em> <em>decreases</em><em> </em>[electron shielding], while from left to right, ionisation energy <em>increases</em><em> </em>[valence shell stability]. Noble gases always always possess such high energy of ionisation because they are stable, with Helium having the highest ionisation of all elements.

From top to bottom, <em>electron affinity</em> <em>decreases</em> [decrease in atomic radius], while from left to right, electron affinity <em>increases</em><em> </em>[increase in atomic radius].

There are many more trends, but I have ran out of space, so I will put this in the comments.

I am joyous to assist you anytime.

Consider the following equation. 2H2(g) + O2(g) 2H2O(g); ΔH is negative. Which statement is true? The reaction is endothermic fr
Svetradugi [14.3K]

Answer is: Increased pressure would increase the rate of forming water vapor.

According to Le Chatelier's Principle, the position of equilibrium moves to counteract the change, the position of equilibrium will move so that the concentration of products (water waper) of chemical reaction increase, if:

1) decrease temperature, because this is exothermic reaction (ΔH is negative).

2) increase concentration of reactants (oxygen and hydrogen).

3) increase pressure of the system, so reaction moves to direction where is less molecules.

How many nickel atoms are in a nickel coin with a mass of 3.95g
lyudmila [28]

Answer:

4.05 × 10²² atoms

Explanation:

Step 1: Given data

Mass of nickel: 3.95 g

Step 2: Calculate the moles corresponding to 3.95 g of nickel

The molar mass of nickel is 58.69 g/mol.

3.95 g × (1 mol/58.69 g) = 0.0673 mol

Step 3: Calculate the atoms in 0.0673 moles of nickel

We will use Avogadro's number: there are 6.02 × 10²³ atoms of nickel in 1 mole of atoms of nickel.

0.0673 mol × (6.02 × 10²³ atoms/1 mol) = 4.05 × 10²² atoms
