Answer: When water is added to vinegar, the vinegar's acidity decreases, which results in a higher number on the pH scale. However, diluting vinegar with water can never make it alkaline, because water itself is not alkaline; the pH of the mixture can't be higher than the higher pH value of the two components.
Explanation: it loses acidity. Diluting it can never make it alkaline and the PH mixture can’t be higher.
The thermodynamics of leaching of ilmenite in hydrochloric acid for titania pigment production is an industrial production of nano-sized titanium dioxide (TiO2).
<h3>What is thermodynamics?</h3>
Thermodynamics is defined as the change in the energy of system that brings about work in that system.
The leaching of ilmenite which is a titanium-iron oxide mineral with HCl can lead to the production of titanium dioxide (TiO2).
The use of thermodynamics in this process controls the heat and energy of the leaching system leading to a better yield of final products.

In order to follow the law of conservation of mass, each side must contain an equal amount of each atom
Answer:
The atmosphere refers to the gaseous envelope of earth, comprised of variable gases with definite proportions. The layers of the earth's atmosphere are as follows-
- Troposphere- This layer starts from the ground and extends up to a height of about 10 km. Here, the temperature decreases with the increasing altitude. All the weather phenomenon takes place in this layer.
- Stratosphere- It starts from 10 km and extends up to a height of about 50 km. Here the temperature increases as the altitude increase. This is because of the presence of the ozone layer that receives the harmful UV radiation emitted from the sun.
- Mesosphere- This layer extends from a height of about 50 km to about 80 km above the earth's surface. Here, again the temperature decreases with the increasing altitude.
- Thermosphere- This layer starts from a height of about 80 km and extends up to about 500 km above the ground surface. In this region again the temperature increases with the increasing elevation.
- Exosphere- This layer ranges from about 500 km to 10,000 km above the earth's surface. Here, the temperature gradually increases with the increasing height.
This variation in temperature occurs because of the certain reason. In the troposphere and the mesosphere, the temperature decreases with height because the pressure and height are inversely proportional to each other. The stratosphere experiences increasing temperature because of the presence of the ozone layer that is responsible for holding the greenhouse gases and the harmful UV radiation. The thermosphere and the exosphere experience high temperatures because of the receiving of the direct sunlight. Due to these above reason, there occurs this temperature change in a unique pattern.
To determine the mass of xenon tetrafluoride, we need to know first the number of fluorine atoms present in <span>oxygen difluoride. We need to convert first the mass into moles then make use of the relation of the elements from the chemical formula. Then, use the avogadro's number to convert it to number of atoms. Then, we do the reverse of the steps above but this time for </span><span>xenon tetrafluoride.
25.0 g OF2 ( 1 mol / 54 g ) ( 2 mol F / 1 mol OF2 ) ( 6.022 x10^23 atoms F / 1 mol F ) ( 1 mol / 6.022x10^23 atoms) ( 1 mol XeF4 / 4 mol F ) (207.3 g / 1 mol XeF4) = 47.99 g XeF4</span>
