Coarse and fine adjustment The coarse adjustment knob should only be used with the lowest power objective lens. Once it is in focus, you will only need to use the fine focus. Using the coarse focus with higher lenses may result in crashing the lens into the slide.

Properties of substances can be classified as physical or chemical properties. Which statements describe chemical properties? (C
Tamiku [17]

The correct answers are options C, that is, silver tarnishes and becomes black when exposed to oxygen, and option E, that is, diesel fuel burns when it is heated.  

Chemical changes refer to the modifications in which the chemistry at molecular level is modified as the initial substance gets transformed into a new and different final substance. This change occurs with the dissociation of old bond and production of new bonds respectively.  

Silver gets tarnished and becomes black when exposed to oxygen. This refers to a chemical change as silver a white and lustrous substance gets transformed into a tarnish black final substance. However, silver does not easily react with oxygen at usual circumstances. It easily reacts with sulfur comprising components in the air and generates black compound as Ag₂S.  

Burning of diesel fuel when it is heated. Diesel refers to a mixture of hydrocarbons varying approximately from C₁₀H₂₀ to C₁₅H₂₈. When these hydrocarbons get burnt they generate novel substances, that is, carbon dioxide and water. Hence, it is also a chemical reaction.

Hello!

My argument: Which is better a Ps4 or an Xbox 1


The Ps4 is a better all-round console. The PS4 costs $100 less but has less games than the Xbox 1. The Xbox 1 now came up with dual compatible games. This means that certain games can now run on the Xbox 1 and the Xbox 360. The overall winner is really undetermined. The controller for Xbox has more quicker response time and is specifically built to be an extremely comfortable in your hands. Unlike the PS4 which their controller is built for nothing they really didn't do anything to theirs. Although the console comparisons are the same. The hard drive for the Xbox is non- removable meaning that if you want the hard drive. you would have to break the Xbox to get it . Unlike the Ps4 when you can take it out easily and switch it with any console and still have your data. I am an Xbox fan since for ever but I think that the two consoles are built the same.


Hope it helps!
