Chemistry
1 answer:
nasty-shy [4]3 years ago
8 0

Answer:

no matter is destroyed or created, it merely changes form. In terms of atoms and bonds, there will be the same amount of atoms at the beginning of an experiment as the amount of atoms at the end of experiment. All that will have happened, is that during the reaction, bonds will have been broken and formed making new compounds. However, the amount of atoms remains exactly the same because matter can not be created or destroyed

Hope this helps!

Express in scientific notation. Make sure your answer has the same number of significant figures as the starting value. (1.8 x 1
slamgirl [31]

Answer : The answer is, 0.2\times 10^{-4}

Explanation :

Scientific notation : It is defined as the way or representation of expressing the number that are too big or too small that is written in the decimal form. That means always written in the power of 10 form.

For example : 8000 is written as, 8.0\times 10^3  in this notation, the significant figure is, 1 but 0.8\times 10^4  in this notation, the significant figures are, 2

The given problem are :

\frac{1.8\times 10^{-2}}{9\times 10^2}=0.2\times 10^{-4}

According to the divide and multiplication rules of scientific figures, the final answer is only as precise as the value with the least number of significant figures.

Hence, the answer is, 0.2\times 10^{-4}
