How many protons, electrons, and neutrons does the following isotope contain? 27 A13+

Chemistry

Lapatulllka [165]3 years ago
7 0

Hey there!

27 tells us the sum of protons and neutrons is 27.

Al tells us we have 13 protons.

3+ tells us that there are 3 less electrons than protons.

13 + n = 27

neutrons = 14

13 - 3 = 10 electrons

27Al3+ has 13 protons, 14 neutrons, and 10 electrons.

Hope this helps!

Write a balanced chemical equation for the reaction that occurs when silver (I) oxide decomposes into silver metal and oxygen ga
PolarNik [594]

Explanation:

The grey powder of silver ( I ) oxide i.e.  Ag₂O  breaks down to give a metal called the silver metal and an odorless , colorless gas , which is the oxygen gas .

The balanced chemical reaction is as follows -

Silver oxide ----->  Silver + oxygen

Ag₂O   ------>   Ag  (s)  +  O₂  (g)

The balanced reaction is -

2 Ag₂O (s)  ------>  4 Ag  (s)  +  O₂  (g)

A 1,900-m3 water tower has been cleaned with a chlorine solution. The vapors of chlorine in the tower exceed allowable concentra
yaroslaw [1]

Answer:

t = 1862 s

Explanation:

To do this, we need first to determine the theorical detention time, which can be determined with the following expression:

t₀ = ∀/Q  (1)

Where:

t₀: detention time

∀: Volume of the fluid in the reactor

Q: Flow rate in the reactor

With this time, we must use the following expression to determine the time that the workers will take to vent the tank:

C = C₀ e^(-t/t₀)   (2)

From here, we must solve for time t, and the expression will be:

t = ln(C₀/C) * t₀   (3)

Now that we know the expression to use, let's solve for t. Using (1) to determine the detention time, ∀ is 1900 m³, and Q is 2.35 m³/s so:

t₀ = 1900 / 2.35 = 808.51 s

Now, let's solve for the time t. C will be 0.0015 mg/L (or 1.5 mg/m³ cause in 1 m³ we have 1000 L) and C₀ 15 mg/m³:

t = ln(15/1.5) * 808.51

<h2>t = 1861.66 s or simply 1862 s</h2><h2></h2>

Hope this helps
