Answer:
The mass of silver block = 73.95 g
Explanation:
Given,
For water:
Mass = 100.0 g
Initial temperature = 24.8 °C
Final temperature = 26.2 °C
Specific heat of water = 4.184 J/g°C
For silver:
Mass = x g
Initial temperature = 59.4 °C
Final temperature = 26.2 °C
Specific heat of water = 0.2386 J/g°C
Heat gain by water = Heat lost by silver
Thus,
Where, negative sign signifies heat loss
Or,
So,
<u>Hence, the mass of silver block = 73.95 g</u>
Answer: the answer would be B
It is a group of atoms that have bonded together to form a larger unit, such as water (H2O), carbon dioxide (CO2), and sugar (C6H12O6). c:
Answer: Acid rain.
Explanation:
According to some experts, acid precipitation can lead to acid rain. Acid rain is a product of chemical reactions caused by the release of compounds such as sulfur dioxide and nitrogen oxides into the air. These substances can form in the atmosphere itself and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.
There are specific theories that nitrogen oxides cause acid rain, in other sulfur oxides, which are produced by the combustion of coal or petroleum products, for example, in thermal power plants, automobile engines, and plants for the production and purification of metals. With water vapor, they produce nitric or sulfuric acid, respectively. This natural disaster is very bad for flora and fauna, it has a particular negative reflection on forests and the aquatic world, especially fish.
