.A solution that serves as a pH indicator may be made using red cabbage, which is frequently available in homes. In essence, the color of the cabbage depends on the acidity of the solution and a pigment molecule called flavin or anthocyanin.
To determine whether a material is an acid or a base, red cabbage indicator is a purple-colored solution
Vinegar is an acid and its pH value is less than 7 and hence
Red color is produced
Baking soda is base and its pH value is greater than 7 and between 8-9
and the color produced is sky blue
Bleach is the green which is also a basic and because the pH value is 10-11
Householder cleaner is having pH 11-13 which is basic and hence the yellow is the color of household cleaner .
A basic solution goes away from being basic and toward the center of the pH scale when an acid is introduced. The base is "neutralized" in this manner.

Answer:
From the given variable values, we can calculate the density of the rock sample to be = 10750_Kg/m^3
Explanation:
To solve this question, we recollect that density is the mass per unit volume of a substance and the SI unit of density is Kg/m^3 with symbol
ρ
The given variables are as follows
mass of rock sample = 8.6g
The volume displaced in the graduated cylinder is
(Final volume level of the cylinder) - (initial volume level of the cylinder)
13.6ml - 12.8 ml= 0.8ml = volume of the rock sample
Therefore, density = 8.6/0.8 = 10.75g/ml = or 1000×10.75 Kg/m^3 =10750Kg/m^3
Density of the rock sample is 10750Kg/m^3
To solve this we assume that the gas inside the
balloon is an ideal gas. Then, we can use the ideal gas equation which is
expressed as PV = nRT. At a constant pressure and number of moles of the gas
the ratio T/V is equal to some constant. At another set of condition of
temperature, the constant is still the same. Calculations are as follows:
T1 / V1 = T2 / V2
V2 = T2 x V1 / T1
V2 = 231 x 556 / 278
V2 = 462 cm³
Answer:
The answer is
<h2>33.0 mL</h2>
Explanation:
The volume of a substance when given the density and mass can be found by using the formula
<h3>
![volume = \frac{mass}{density}](https://tex.z-dn.net/?f=volume%20%3D%20%20%5Cfrac%7Bmass%7D%7Bdensity%7D%20)
</h3>
From the question
mass = 89.4 g
density = 2.71 g/mL
The volume is
![volume = \frac{89.4}{2.71} \\ = 32.9889298892...](https://tex.z-dn.net/?f=volume%20%3D%20%20%5Cfrac%7B89.4%7D%7B2.71%7D%20%20%5C%5C%20%20%3D%2032.9889298892...)
We have the final answer as
<h3>33.0 mL</h3>
Hope this helps you
To be fair, you have to have a very high IQ to understand Rick and Morty. The humour is extremely subtle, and without a solid grasp of theoretical physics most of the jokes will go over a typical viewer's head. There's also Rick's nihilistic outlook, which is deftly woven into his characterisation- his personal philosophy draws heavily from Narodnaya Volya literature, for instance. The fans understand this stuff; they have the intellectual capacity to truly appreciate the depths of these jokes, to realise that they're not just funny- they say something deep about LIFE. As a consequence people who dislike Rick & Morty truly ARE idiots- of course they wouldn't appreciate, for instance, the humour in Rick's existential catchphrase "Wubba Lubba Dub Dub," which itself is a cryptic reference to Turgenev's Russian epic Fathers and Sons. I'm smirking right now just imagining one of those addlepated simpletons scratching their heads in confusion as Dan Harmon's genius wit unfolds itself on their television screens. What fools.. how I pity them.
And yes, by the way, i DO have a Rick & Morty tattoo. And no, you cannot see it. It's for the ladies' eyes only- and even then they have to demonstrate that they're within 5 IQ points of my own (preferably lower) beforehand. Nothin personnel kid
