Which statement does NOT correctly compare silicon with another element? A) Silicon is a better conductor of electricity than su
Vesna [10]

Answer:


Step-by-step explanation:

Silicon is a member of Group 14 (IVA) in the periodic table. The periodic table is a chart that shows how chemical elements are related to one another. Silicon is also part of the the carbon family. Other carbon family elements include carbon, germanium, tin, and lead. Silicon is a metalloid, one of only a very few elements that have characteristics of both metals and non-metals.

Silicon is the second most abundant element in the Earth's crust, exceeded only by oxygen. Many rocks and minerals contain silicon. Examples include sand, quartz, clays, flint, amethyst, opal, mica, feldspar, garnet, tourmaline, asbestos, talc, zircon, emerald, and aquamarine. Silicon never occurs as a free element. It is always combined with one or more other elements as a compound.By the early 1800s, silicon was recognized as an element. But chemists had serious problems preparing pure silicon because it bonds (attaches) tightly to oxygen. It took chemists many years to find out how to separate silicon from oxygen. That task was finally accomplished in 1823 by Swedish chemist Jons Jakob Berzelius (1779-1848).

Silicon's most important application is in electronic equipment. Silicon is one of the best materials from which to make transistors and computer chips. The total weight of silicon used for this purpose is relatively small. Much larger amounts are used, for example, to make metal alloys. An alloy is made by melting and mixing two or more metals. The mixture has properties different from those of the individual metals.

If the area of a square is 36 inches what is the length of one side?
Pavel [41]
To find the length of a square given the area, we just need to take the square root of the area given. The sqrt of 36 is 6, so each side is 6 inches. :)

The Floyds have considered three options to ensure they have at least $1,375 saved for their trip.
ANTONII [103]

I am guessing you are talking about Option 3. They start with $125. So they times it by 1.25 as we are using the multiplier method. So in the First month, it will be 156.25. Second it will be 195.3125. So in August it will be $476.837157. Of couse round it and you will get $476.84.

I believe there is a more efficent way of doing this but I have forgotten.

Tegan needs to make 686868 more snow blocks to finish building an igloo. Write an equation for the number of blocks Tegan still
Keith_Richards [23]

Answer:

We are given:

No: of blocks Tegan still needs to make = m.

No: of blocks Tegan has completed = c

Total No:of more snow blocks need to make = 68 .

Total number of more snow blocks need to make = Total number of blocks -  The number of blocks Tegan has completed.

m = 68 - c.

Therefore, the equation for the number of blocks Tegan still needs to make, m, when she has completed c blocks is

m = 68 - c.

For example.

Suppose if c = 10, it means Tegan still needs to make 68-10 = 58 block.
