Compare a sodium ion and neutral sodium atom in size. what causes the size difference

Chemistry
1 answer:
n200080 [17]3 years ago
4 0
A cation is smaller than its parent atom.
Therefore, here a sodium ion is smaller than the neutral sodium atom.

Reason: Since the sodium atom loses an electron to form an electropositive ion(cation), its nuclear charge increases(the number of protons exceeds the number of electrons) and the orbital electrons are pulled with a greater energy.
Thus,the sodium ion shrinks in size.

bromine gas and nitric oxide can combine to form nitrosyl bromide, nobr. br2 (g) 2 no (g) ⇌ 2 nobr (g) if the reaction has reach
Vadim26 [7]

The reaction would shift to the right (forward).

Balanced chemical reaction: Br2(g) + 2NO(g) ⇌ 2NOBr(g)

According to the Principle the position of equilibrium moves to counteract the change.

The equilibrium shift to the right, so more product (nitrosyl bromide) will be produced. If the product is removed, the reactants will react to produce that product and set equilibrium.

Concentration of the reactants (bromine gas and nitric oxide) is reducing, while concentration of product is increasing.

In a chemical reaction, chemical equilibrium is the state in which both reactants and products are present in concentrations which not change with time.

Speed of direct and irreversible chemical reaction are equal

4.4 mol nitrogen.<br><br> VN2 = ____L
Arlecino [84]

Answer:

99 L

Explanation:

Step 1: Given data

Moles of nitrogen: 4.4 moles

Step 2: Calculate the volume occupied by 4.4 moles of nitrogen

The volume occupied by a gas depends on other conditions such as pressure  (P) and temperature (T). If we have this information, we can calculate the volume of the gas using the ideal gas condition.

P × V = n × R × T

Since the task doesn't inform the conditions, we can assume it is under standard pressure (1 atm) and temperature (273.15 K). At STP, 1 mole of any gas occupies 22.4 L.

4.4 mol × 22.4 L/1 mol = 99 L
