Answer:
Explanation:
Its a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. These substances rise high into the atmosphere in which they mix and react with water, oxygen, and other chemicals to form more acidic pollutants.
Answer:
If you multiply the miles per hour (30) by 60 (the amount of minutes in an hour) you should get the number for miles per minute. if you multiply that number by 60, you should get the number for miles per second.
A mixture is a new substance that you get when you mix two or more different substances together and blend them so you either create a homogeneous mixture or a heterogeneous one. In your case (assuming that your choices are aqueous ammonia, liquid mercury, gaseous ethane, solid iodine), the correct answer is aqueous ammonia, given that it is a mixture of ammonia and water, whereas the other options are not mixtures because they only consist of one element.
Explanation:
In chemistry, a combination forms once 2 or additional substances are combined such every substance retains its own chemical identity. Chemical bonds between the elements area unit neither broken nor fashioned. Note that albeit the chemical properties of the elements haven't modified, a combination could exhibit new physical properties, like boiling purpose and freezing point. For instance, combining along water and alcohol produces a combination that features a higher boiling purpose and lower freezing point than alcohol.
