One way to slow down the global climate change is to reduce the use of nonrenewable sources such as fossil fuels because, they release harmful gases that leads to global warming.
What is global warming?
The increase in the overall atmospheric temperature is called global warming. Global warming is mainly caused by green house gases such as carbon dioxide, methane, oxides of nitrogen etc.
Green house gases intensely absorbs heat energy that radiates out from earth. Thus they trap the temperature in the atmosphere make the planet warmer.
Nonrenewable energy sources such as nuclear reactions, fossil fuels, coal etc. coal and petroleum are highly rich in toxic gases and burning them releases these gases including carbon dioxide and methane to the atmosphere increase the rate of global warming.
Therefore, reducing the use of nonrenewable resources is a good way to slow down the global climate change.

El peso equivalente del metal se calcula por regla de tres simple:
Answer:
El peso equivalente del metal es 1/20 g
Explanation:
Una muestra contiene 160 g de bromo y 2 g de hidrógeno. Otra muestra de bromuro metálico contiene 4 g de bromuro y 1 g de metal. Encuentra el peso equivalente del metal
Aquí tenemos la primera muestra que tiene la relación de bromo a hidrógeno de 160 g de bromo a 2 g de hidrógeno.
Eso es 160 g de bromo está presente con 2 g de hidrógeno
Dividiendo la combinación anterior por 160 para encontrar la cantidad de hidrógeno que se combina con 1 g de bromo, tenemos
(160 g) / 160 de bromo está presente con (2 g) / 160 de hidrógeno
1 g de bromo está presente con 1/80 g de hidrógeno
Por lo tanto, 4 g de bromo están presentes con 4/80 g de hidrógeno o tenemos;
4 g de bromo están presentes con 1/20 g de hidrógeno
Por lo tanto, el peso equivalente del metal = 1/20 g.

A mixture of sand and table salt can be separated by filtration because the substances in the mixture differ in solubility in water. Thus, the correct option for this question is D.
What is meant by Solubility?
Solubility may be defined as the phenomenon in chemistry that involves the maximum amount of a substance that will significantly be disbanded in a given amount of solvent at a particular temperature.
The answer to the above question is better understood by the fact that when you mix both salt and sand in the water, you may find that salt is completely soluble in water while sand is not. This is because the bond of water is not competent enough to dissolve the sand.
Therefore, the correct option for this question is D.

(2) The entropy of the LiBr(aq) is less than the entropy of the water.
(3) The dissolving of the LiBr(s) in water is an endothermic process.
(4) The dissolving of the LiBr(s) in water is an exothermic process.
Answers
The statement best explains why the thermometer reading initially increases when LiBr(s) is dissolved in the water is the dissolving of the LiBr(s) in water is an exothermic process.
What is a thermometer?
A thermometer is an instrument that is used to measure the temperature of an object.
An exothermic process is in which the heat and energy is released in the outer system.
Thus, the correct option is (4) The dissolving of the LiBr(s) in water is an exothermic process.

Final answer:
The rate of cooling of the water is 2.5°C per minute, calculated by using the difference in temperature over the time interval and assuming a linear rate of cooling.
Explanation:
The rate of cooling of water is the change in temperature over time. If the temperature of water drops from 60 degrees Celsius to 35 degrees Celsius in ten minutes, we can calculate the rate by subtracting the final temperature from the initial temperature and then dividing by the time elapsed. The formula for the rate of cooling is:
Rate of cooling = (Initial Temperature - Final Temperature) / Time
In this case:
Rate of cooling = (60°C - 35°C)/10 minutes = 2.5°C per minute
This calculation assumes that the cooling process follows a linear rate, which might not be the case in real-world scenarios as the rate can change over time due to various factors such as the properties of the container, the environment, and the volume of water.
