A transform boundary occurs when two tectonic plates move past one another.
What causes tectonic plates to move? What is a convergent boundary? What is a divergent boundary? What is a transform boundary? What is a transform boundary?
Tectonic Plates Movement:
The tectonic plates can be thought like the pieces of the broken or cracked shells. The heat from radioactive processes within the planet's interior causes the plates to move, The heat from radioactive processes within the planet's interior causes the movement of the tectonic plates.
Convergent Boundary:
Convergent boundary is that area or is that boundary from which the plates moves towards each other.
Divergent Boundary:
Divergent boundary is that boundary or area from which the tectonic plates starts moving away from each other.
Transform boundary:
The transform boundary is that boundary which causes a fault or error between the tectonic plates.
So we can conclude that a transform boundary occurs when two tectonic plates move past one another.

Josh prepares a solution by mixing sodium nitrate and water. To calculate the molarity of the solution, Josh should calculate the moles of which substance, and why?
sodium nitrate, because it is the solvent
sodium nitrate, because it is the solute
water, because it is the solvent
water, because it is the solute
Answer:
sodium nitrate, because it is the solute
Explanation:
To find the molarity of the solution, Josh should determine the number of moles of the sodium nitrate.
Molarity is defined as the number of moles of solutes in a given volume of solution.
Molarity = [tex]\frac{n}{v}[/tex]
n is the number of moles of solute
v is the volume of solution
Answer:
C: sodium nitrate, because it is the solute

If the theoretical yield of the reaction below corresponds to 99.2 g and the actual yield was 60.9 g, calculate the percent yield.
Given: Li2O + H202LiOH
20
Answer:
61.39%
Explanation:
The percent yield of a substance can be calculated using the formula:
Percent yield = actual yield/theoretical yield × 100%
Based on the information provided on the reaction in this question, the theoretical yield is given as 99.2g while the actual yield is given as 60.9g.
Hence, the percent yield is calculated thus:
% yield = 60.9/99.2 × 100
% yield = 0.6139 × 100
% yield = 61.39%
The percent yield is 61.39%

How can biologic weathering result in chemical erosion?
plants transpire water vapor
bacteria release acids and other agents that break down rock
large herds trample rocks and break up soil
roots loosen soil and break rocks
Answer:
bacteria release acids and other agents that break down rock
Explanation:
One of the ways in which biological weathering results in chemical erosions is through bacteria releasing acids and other agents to break down a rock.
Weathering is defined as the physical disintegration and chemical decomposition of rocks to form sediments and soils.
The process of erosion removes the weathered materials from the earth surface.
Chemical weathering involves the decay of rocks by chemical means.
The bacteria is a biological organismAs it releases its acids and the rocks begin to break down, biological weathering takes placesWhat type of soil is best for growing plants?

calculate the number of magnesium atoms in a 120.0g sample of forsterite mg2sio4. be sure your answer has a unit symbol if necessary, and round it to 4 significant digits.
The number of magnesium atoms present in forsterite are 10.272 x 10²³
Equation :First we have to calculate the moles of magnesium
moles of forsterite = mass of forsterite / molecular mass of forsterite
moles of forsterite = 120.0 g / 140.69 g/mol
moles of forsterite = 0.8529 mole
Now we have to calculate the number of magnesium atoms
The formula of forsterite is mg2sio4
In the forsterite molecule, there 2 atoms of magnesium, 1 atoms of silicon and 4 atoms of oxygen.
As, 1 mole of forsterite contains 2 x 6.022 x 10²³ number of magnesium
So, 0.8529 mol of forsterite contains
= 0.8529 x 2 x 6.022 x 10²³
= 10.272 x 10²³ number of magnesium atoms
Therefore, the number of magnesium atoms present in forsterite are 10.272 x 10²³.

When 8.0 moles of chromium react, how many moles of chromium (lll) oxide are produced?
Moles of chromium (lll) oxide produced : 4 moles
Further explanationThe reaction equation is the chemical formula of reagents and product substances
A reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reagents and products.
Reaction
4Cr+3O₂⇒2Cr₂O₃
moles of Cr=8 moles
From the equation, mol ratio Cr : Cr₂O₃ = 4 : 2, so mol Cr₂O₃ :

A student used a pipette to add 25.0 cm of KOH of unknown concentration to
a conical flask.
The student carried out a titration experiment to find the volume of 0.150 mol/dmº
H2SO4 needed to neutralise the KOH.
The student found that, on average, 17.20 cm of the H2SO4 solution was
required for neutralisation.
Calculate the concentration of the KOH solution.
The concentration of the KOH solution = 0.2064 M
Further explanationTitration is a procedure for determining the concentration of a solution (analyte) by reacting with another solution whose known concentration (usually a standard solution) is called the titrant. Determination of the endpoint/equivalence point of the reaction can use indicators according to the appropriate pH range
Acid-base titration formula

At normal temperature and pressure, hydrogen chloride (HCl), a gas composed of the element's hydrogen and chlorine, is a gas.
An aqueous solution of hydrogen chloride is what is known as hydrochloric acid, commonly referred to as muriatic acid. It has an unmistakably strong odor and is colorless. It is categorized as a powerful acid. In the digestive tracts of the majority of animal species, including humans, it is a part of the stomach acid. In the food, textile, metal, and rubber sectors, hydrogen chloride (HCl) is frequently employed as a bleaching agent to neutralize alkaline substances. When discharged into the soil, it is neutralized, and when it comes into contact with water, it hydrolyzes quickly.
