When fluoride reacts with the metal it forms an F negative ion the fluorine Adam has gained an electron an undergone _______.

Chemistry
1 answer:
Anika [276]3 years ago
4 0

Answer:

Reduction.

Explanation:

Fluorine atom has gained an electron and undergone reduction because when an atom gains electron it reduced itself thus acting as an oxidant to oxidize another atom .

   For exam sodium fluoride  NaF is a salt when sodium fluoride undergo breakdown at that time the fluoride atom gains an electron and is converted to F- anion by the process called reduction .

Aluminum has a specific heat capacity of 0.902 J/g °C. How much energy is released when 1.0 kg
Ghella [55]

Answer:

The energy released is 13.53j

Explanation:

Q = Mc∆temp.

Q = energy

M = mass

c = specific heat capacity

∆temp. = change in temperature

Q = 1 x 0.902 x (35 - 20)

Q = 0.902 x 15 = 13.53j

How much does 0.0273 moles of Na2O weigh
devlian [24]

Answer:

1.69 g Na₂O

General Formulas and Concepts:

<u>Chemistry - Atomic Structure</u>

  • Reading a Periodic Table
  • Using Dimensional Analysis

Explanation:

<u>Step 1: Define</u>

0.0273 mol Na₂O

<u>Step 2: Identify Conversions</u>

Molar Mass of Na - 22.99 g/mol

Molar Mass of O - 16.00 g/mol

Molar Mass of Na₂O - 2(22.99) + 16.00 = 61.98 g/mol

<u>Step 3: Convert</u>

<u />0.0273 \ mol \ Na_2O(\frac{61.98 \ g \ Na_2O}{1 \ mol \ Na_2O} ) = 1.69205 g Na₂O

<u>Step 4: Check</u>

<em>We are given 3 sig figs. Follow sig fig rules and round.</em>

1.69205 g Na₂O ≈ 1.69 g Na₂O

You are asked to write observations about a 100g sample of Nitrogen-16 before it decays, but you're running late. In order to ma
san4es73 [151]

Answer:

You cannot make observations if you are 57 seconds late into the lab.

Explanation:

The atomic nucleus can split by decay into 2 or more particles as a result of the instability of its atomic nucleus due to the fact that radioactive elements possess an unstable atomic nucleus.

Now, the primary particles which are emitted by radioactive elements in order to make them decay are alpha, beta & gamma particles.

The half life equation is;

N_t = N₀(½)^(t/t_½)

Where:

t = duration of decay

t_½ = half-life

N₀ = number of radioactive atoms initially

N_t = number of radioactive atoms remaining after decay over time t

We are given;

t = 57 secs

N₀ = 100 g

Now, half life of Nitrogen-16 from online sources is 7.2 seconds. t_½ = 7.2

Thus;

N_t = 100(1/2)^(57/7.2)

N_t = 0.4139g

We are told that In order to make observations, you require at least .5g of material.

The value of N_t you got is less than 0.5g, therefore you cannot make observations if you are 57 seconds late.
