It's B.Rock and mineral fragments.
67,029 to three significant figures
0.15 to one significant figure
52.8005 to five significant figures
3.17497 to three significant figures
a) 67000 b) 0.20 c) 52.8010 d) 3.17000 are the answers respectively.
Distance is a physical quantity which is measured in meter. If a man travel then it is measured in meters that defines that how much he travel from one point to another point for all these type of things we use to measure distance.
Centimeter is also a physical quantity which is use to measure distance. 1 centimeter is equal to 0.01 meter and 1 centimeter is equal to 0.00001 kilometer.the kilometer is large quantity to measure distance while centimeter is smaller quantity to measure distance.
Kilometer is also a physical quantity which use to measure the distance 1 kilometer is equal to 1000 mtr and 1 kilometer is equal to 100000 centimeter.
For above conclusion, we easily states that the kilometer is large quantity to measure distance while centimeter is smaller quantity to measure distance. Centimeter is also a physical quantity which is use to measure distance. 1 centimeter is equal to 0.01 meter and 1 centimeter is equal to 0.00001 kilometer.
Therefore, a) 67000 b) 0.20 c) 52.8010 d) 3.17000 are the answers respectively.

WARNING: DON'T PUT LINKS I WILL REPORT YOU!
If you have 1.0 mole of each of the following compounds, which will have the most molecules?
Х
NI3 (nitrogen triiodide)
KCI (potassium chloride)
Lici (lithium chloride)
O C2H2 (ethyne)
O They all have the same number of molecules.
7
1/1 point
fn 35 moles of Iron (Fe)?
Answer:
6. They all have the same number of molecules.
7. 19.5 g
Explanation:
6. From Avogadro's hypothesis, we understood that 1 mole of any substance contains 6.02×10²³ molecules i.e
1 mole = 6.02×10²³ molecules
Considering the question given above, each compounds has just 1 mole. Thus, they will also have the same number of molecules.
7. Determination of the mass of iron (Fe)
Number of mole of Fe = 0.35 mole
Molar mass of Fe = 55.85 g/mol
Mass of Fe =?
Mass = mole × molar mass
Mass of Fe = 0.35 × 55.85
Mass of Fe = 19.5 g
Thus, the mass of 0.35 mole of iron (Fe) is 19.5 g
