Answers
Answer:
Mechanical weathering:
It is the physical breakdown of rocks and minerals into smaller fragments without changing their chemical composition.
It occurs due to external forces such as freeze-thaw cycles, abrasion, and plant roots expanding.
Chemical weathering:
It is the alteration of rock or mineral material into new compounds as a result of chemical reactions with water, air, and acids.
It occurs due to the reaction of minerals with water, carbon dioxide, oxygen, and other agents to form new compounds such as oxides, hydroxides, and carbonates.
Both:
Both processes work together to break down and transform the earth's crust.
Both processes are essential for soil formation and the creation of new landscapes over geological time scales.

WHERE IS ENERGY STORED DURING PHOTOSYNTHESIS?
O starch
O oxygen
O valence electrons
O chemical bonds
please help I'm confused
Answers
Answer:
it is the chlorplasts
Explanation:
Photosynthesis is the process plants and some algae use to convert light energy to chemical energy stored as sugar within chloroplasts -- the energy factories found in plant cells.
Energy is stored in chemical bonds during photosynthesis.
During photosynthesis, the radiant energy from the sun is converted to chemical energy in carbohydrates.
Inorganic materials in the form of carbon dioxide and oxygen combine to form carbohydrates in the presence of radiant energy according to the equation below:
\(6CO_2 + 6H_2O ---> C_6H_1_2O_6 + 6O_2\)
The energy is thus, stored in chemical bonds in the carbohydrate and this is what is oxidized during respiration to release the locked energy.

Which seismic waves are call “push/pull” because they compress and extend as theymove through the earth? *
Which type of seismic wave can move through solid layers of the earth but not through the liquid outer core? *
Which seismic wave is the first to reach a seismic station, and therefore is the fastest? *
Answers
Answer:
1.A 2.P waves are the fastest kind of seismic wave. a longitudinal P wave has the ability to move through solid rock and fluid rock, like water or the semi-liquid layers of the earth. It pushes and pulls the rock it moves through in the same way sound waves push and pull the air. 3.The second type of body wave is the S wave or secondary wave, which is the second wave you feel in an earthquake. An S wave is slower than a P wave and can only move through solid rock, not through any liquid medium. It is this property of S waves that led seismologists to conclude that the Earth’s outer core is a liquid. 4.P Waves The first kind of body wave is the P wave or primary wave. This is the fastest kind of seismic wave, and, consequently, the first to 'arrive' at a seismic station. The P wave can move through solid rock and fluids, like water or the liquid layers of the earth.Explanation:

what is an interesting fact about the first 10 atoms in the periodic table??? Please answer..
Answers
Answer:
Although Dmitri Mendeleev is most often cited as the inventor of the modern periodic table, his table was just the first to gain scientific credibility. It wasn't the first table that organized the elements according to periodic properties.
There are about 94 elements on the periodic table that occur in nature. All of the other elements are strictly human-made. Some sources state more elements occur naturally because heavy elements may transition between elements as they undergo radioactive decay.
Technetium was the first element to be made artificially. It is the lightest element that has only radioactive isotopes (none are stable).
The International Union of Pure Applied Chemistry, IUPAC, revises the periodic table as new data becomes available. At the time of this writing, the most recent version of the periodic table was approved in December 2018.
The rows of the periodic table are called periods. An element's period number is the highest unexcited energy level for an electron of that element.
Columns of elements help to distinguish groups in the periodic table. Elements within a group share several common properties and often have the same outer electron arrangement.
Most of the elements on the periodic table are metals. The alkali metals, alkaline earths, basic metals, transition metals, lanthanides, and actinides all are groups of metals.
The present periodic table has room for 118 elements. Elements aren't discovered or created in order of atomic number. Scientists are working on creating and verifying elements 119 and 120, which will change the appearance of the table, though they were working on element 120 before element 119. Most likely, element 119 will be positioned directly below francium and element 120 directly below radium. Chemists may create much heavier elements that may be more stable because of the special properties of certain combinations of proton and neutron numbers.
Although you might expect atoms of an element to get larger as their atomic number increases, this does not always occur because the size of an atom is determined by the diameter of its electron shell. In fact, element atoms usually decrease in size as you move from left to right across a row.
The main difference between the modern periodic table and Mendeleev's periodic table is that Mendeleev's table arranged the elements in order of increasing atomic weight, while the modern table orders the elements by increasing atomic number. For the most part, the order of the elements is the same between both tables, though there are exceptions.

How many sulfur atoms are generated when 9.42 moles of H2S react according to the following equation: 2H2S+SO2→3S+2H2O
A) 8.51 × 10^24
B) 3.78 × 10^24
C) 8.51 × 10^23
D) 9.42 × 10^23
Answers
Answer:
A) 8.51 × 10²⁴
Explanation:
1. Gather all the information
2H₂S + SO₂ ⟶ 3S + 2H₂O
n/mol: 9.42
2. Calculate the moles of S atoms
The molar ratio is 3 mol S:2 mol H₂S
\(\text{Moles of S} = \text{9.42 mol H$_{2}$S} \times \dfrac{\text{3 mol S }}{\text{2 mol H$_{2}$S }} = \text{14.13 mol S}\)
3. Calculate the atoms of S
\(\text{Atoms of S } = \text{14.13 mol S} \times \dfrac{6.022 \times 10^{23}\text{ S atoms}}{\text{1 mol S}} = \mathbf{8.51 \times 10^{24}}\textbf{ S atoms}\)
The sulfur atoms that should be generated is \(A) 8.51 \times 10^24\).
Given that,
9.42 moles of H2S reacted to the given equation.Also, 1 mole for the substance contains \(6.022 \times 10^23\) no of atoms & molecules. The calculation is as follows:\(= \frac{3\times 6.022\times 10^23\times 0.42}{2}\\\\= 85.0909 \times 10^23\\\\= 8.509 \times 10^24\\\\= 8.51 \times 10^24\)
Therefore we can conclude that the sulfur atoms that should be generated is \(A) 8.51 \times 10^24\).

Nicole has 2 glasses on the counter: one of water and one of sugar-water. She is baking a cake and needs to use the sugar-water for the glaze. Both glasses look identical, but one contains a mixture and the other contains a compound.
Is sugar-water a mixture or a compound? Define mixtures and compounds, and explain how, without tasting it, Nicole can test to make sure she is using the sugar-water in the glaze.
Answers
Answer:
sugar-water is a mixture not a compound.(homogeneous mixture.)
Explanation:
Compounds are substances formed by the chemical combination of two or more elements. Mixtures are substances formed by physically mixing two or more substances together.
The solution of sugar in water is considered a mixture not a compound because the particles of sugar and water are not completely dissolve nor mixed in a fixed proportion or ratio. hope this helped :)
Answer: Nicole can take a small amount of sample from both of the glasses, she can place the samples in two separate containers and leave them out in the sun, so that the water gets evaporated. One of the two containers will contain a residue of sugar. The one containing the sugar residue, is the sugar-water solution.

What happens to the atoms that make up hydrogen fuel as it burns?
Answers
Answer:
When hydrogen fuel burns, its atoms combine with oxygen atoms in the air, which creates a chemical reaction that releases energy in the form of heat and light. The hydrogen atoms lose their outermost electrons, becoming positively charged ions (protons). These ions combine with the oxygen atoms to form water molecules (H2O), which evaporate into the air as steam. Therefore, the atoms that make up hydrogen fuel ultimately become part of water molecules during the process of combustion.
