A rock that forms when magma hardens beneath Earth's surface is called an intrusive igneous rock.
The teacher
should discuss safety procedure with students at the beginning of the experiment
or laboratory assignment. The teacher
should give list of rules for students.
1.
Always wear safety goggles.
2.
Never
touch or rub eyes of face during science investigation.
3.
Keep lids on when not in use.
4.
Never use broken/chipped glassware.
A haploid cell is a cell typically with half the number of chromosomes (a sex cell) used for reproduction.
A diploid cell is the opposite, a full set of chromosomes not intended for sexual reproduction but typically used in mitosis.
<h3>Answer</h3>
15 = 1.5 × 10^1
1.5 =1.5 × 10^0
0.015 = 1.5 × 10^-2
0.15 = 1.5 × 10^-1
150 = 1.5 × 10^2
<h3>How to convert to scientific notation</h3>
- Move the decimal point in your number until there is only one non-zero digit to the left of the decimal point. Let says it is X
- Count how many places you moved the decimal point. Let say it is Y.
- If you moved the decimal to the left b is positive.
- If you moved the decimal to the right b is negative.
- If you did not need to move the decimal b = 0.
- Write your scientific notation number as X x 10^Y.
Answer:
Azurite and Magnesite react with hydrochloric acid.
Explanation:
These 2 rocks contain the carbonate mineral calcite dolomite. Carbonate minerals are unstable in contact with hydrochloric acid. When acid begins to effervesce (fizz) on a specimen, a reaction takes place and bubbles of carbon dioxide evolve, thus indicating the presence of minerals like calcite dolomite.
Hope my answer is correct and helpful :)
