7 0

Answer:

Option D, Index fossil helps scientists to determine the relative ages of rocks by their positions

Explanation:

Index fossils are arranged in layer in such a way that the lowest layer represent the oldest fossil and the top most layer represents the youngest fossil. Scientist use this concept to determine the relative age of the rocks based on their position beneath the earth’s surface

Hence, option D is correct

_________ drives most natural processes in the atmosphere, like the water cycle and weather phenomena.
Semenov [28]

Answer:

The correct answer is the a=heat

Explanation:

Hello! Let's solve this!

Heat is responsible for regulating the temperature on Earth. When the temperature rises, the evaporation of water occurs, so it influences the water cycle. It also influences the climatic phenomena by increasing and lowering the temperature.

The correct answer is the a=heat

Which element, if combined with chlorine, will have the greatest attraction for the chlorine electrons? N P As
motikmotik

The Nitrogen (N) will have the greatest attraction for the chlorine electrons.

Answer: A) N

Explanation

The tendency or the ability to attract electrons is termed as electronegativity.

The electronegativity tend to increase from left to right in the periods and bottom to top in the groups of the periodic table. So it is known that the halogen group consists of the most electronegative elements.

Though chlorine has high electronegativity of 3.16, the electrons of chlorine can be attracted by other electronegative elements provided that their electronegativity should be in the range of the electronegativity of Cl.

So among the elements given, Nitrogen (N) has an electronegativity of 3.04, Phosphor (P) has an electronegativity of 2.19 and Arsenide electronegativity is 2.18.

Thus it can be seen that the electronegativity is maximum for Nitrogen among the three elements so it should have the greatest tendency to attract Cl electrons.

Calculate the mass of hydrogen in 500 g of Al(C2H3O2)3
Zigmanuir [339]
<span>Answer is: the mass of hydrogen is 22,05 grams.
m(</span>Al(C₂H₃O₂)₃)<span> = 500 g.
M</span>(Al(C₂H₃O₂)₃) = 27 + 6 ·12 + 9 · 1 + 6 · 16 · g/mol = 204 g/mol.<span>
n</span>(Al(C₂H₃O₂)₃) = m(Al(C₂H₃O₂)₃) ÷ M(Al(C₂H₃O₂)₃).
n(Al(C₂H₃O₂)₃) = 500 g ÷ 204 g/mol.
n(Al(C₂H₃O₂)₃) = 2,45 mol.
n(Al(C₂H₃O₂)₃) : n(H) = 1 : 9.
n(H) = 22,05 mol.
m(H) = 22,05 mol · 1 g/mol
m(H) = 22,05 g.
