1. Lemon juice (pH 2.2) = Acidic

2. Salt solution (pH 7) = Neutral

3. Baking soda (pH 9) = Alkaline

4. Bleach (pH 13) = Alkaline

5. Tomato juice (pH 4) = Acidic

6. Gastric juices (pH 1) = Acidic

<h3>Explanation: </h3>

The pH scale measures how acidic or alkaline a substance is. The pH scale ranges from <u>0 to 14.</u>

A pH of 7 is neutral.

Acidic substances have pH less than 7.

Alkaline(Base) substances have a pH greater than 7

Hence, the given samples can be categorized as acidic, basic or neutral based on their pH values.

1. Lemon juice (pH 2.2 < 7) = Acidic

2. Salt solution (pH 7 = 7) = Neutral

3. Baking soda (pH 9 > 7) = Alkaline

4. Bleach (pH 13 >7) = Alkaline

5. Tomato juice (pH 4 < 7) = Acidic

6. Gastric juices (pH 1 < 7) = Acidic

How many ozone particles are needed to form 24 particles of oxygen gas?

bearhunter [10]

First, you have to know the chemical formula of ozone and oxygen gas. Oxygen gas is O₂; it is one of the few gases that are diatomic in nature. The chemical formula of ozone is O₃. In oxygen gas, there are 2 particles of the oxygen element, while there are 3 particles for the ozone. There might be a slight difference but this induces a great difference in their properties. Oxygen is essential to living things because this is the gas that we breathe in. However, ozone is not safe to breathe in. It is a very strong oxidizing agent, almost 4 times as strong as the oxygen. Its main function is to block the UV rays from entering the Earth's atmosphere which can be harmful to our health.

Having known their chemical formula and properties, we know that an oxygen gas has 2 particles of oxygen element. So, if there are 24 particles of oxygen gas, that would mean 48 particles of the oxygen element. Since an ozone compound contains 3 particles of the oxygen element, then 48/3 = 16. It would take 16 particles of ozone to form 24 particles of the oxygen gas.

From the balanced reaction below, when you have 3.33 moles of (NH4)2Cr2O7, how many grams of N2 will be produced

natima [27]

Answer:

$m_{N_2}=93.3gN_2$

Explanation:

Hello there!

In this case, for this stoichiometry-based problem, it is firstly necessary to realize that the decomposition of ammonium dichromate is given by:

$(NH_4)_2Cr_2O_7(s)\rightarrow N_2(g)+4H_2O(l)+Cr_2O_3(s)$

Thus, since the mole ratio between ammonium dichromate and the gaseous nitrogen (molar mass = 28.02 g/mol) is 1:1, we can compute the produced mass of the latter via stoichiometry as shown below:

$m_{N_2}=3.33mol(NH_4)_2Cr_2O_7*\frac{1molN_2}{1mol(NH_4)_2Cr_2O_7}*\frac{28.01gN_2}{1molN_2}\\\\ m_{N_2}=93.3gN_2$

Best regards!
