Explanation:
100cm = 1m
1cm=1/100 m
175cm = 175/100 m = 1.75m.
hope this helps you.
If a student is 175 cm tall, then according to the metric system the same student is 1.75 m tall.
What is a Metric system?A metric system may be defined as a type of system that significantly weighs and measures the mass and distance respectively in which the meter is the unit of length and the kilogram is the unit of weight.
A metric system is a standard system of measurement which utilizes the meter, liter, and gram as base units of length for distance, capacity for volume, weight for mass, etc.
According to the question, the height of a student in cm = 175 cm.
Then, from the general conversion rule,
1 meter = 100 cm.
1 cm = 1/100 meter.
175 cm. = 175/100 = 1.75 meters.
Therefore, if a student is 175 cm tall, then according to the metric system the same student is 1.75 m tall.

Zinc metal reacts with aqueous copper(II) chloride, as shown in this equation. If 3.03 x 1021 atoms of zinc react, how many grams of Cu will form? Show the sequence of conversions necessary, then calculate the numerical answer. Zn (s) + CuCl2 (aq) ---> ZnCl2 (aq) + Cu (s)
Answer:
0.320 g Cu.
Explanation:
Hello there!
In this case, case, according to the presented chemical reaction, it is possible to determine that the mole ratio of zinc to copper is 1:1 and therefore, we will have the same amount of atoms for the both of them. Moreover, since one mole of copper contains 6.022x10²³ atoms of this element, with a mass of 63.546 g (molar mass); it is possible for us to write up the following mathematical setup in order to calculate the produced grams of copper:
[tex]3.03x10^{21}atoms Zn*\frac{1atom Cu}{1atom Zn}*\frac{1molCu}{6.022x10^{23}atoms Cu}*\frac{63.546gCu}{1molCu} \\[/tex]
Thus, the numerical result turns out to be:
0.320 g Cu

Is a nonrenewable resource
Explanation:
"The fuel for fusion reactors can be drawn from sea water in an almost unlimited supply. The fuel for fission, on the other hand, comes from a limited supply of uranium. Once it is depleted, it cannot be easily replenished. For this reason, nuclear power is considered a nonrenewable resource."

Lithium arsenate (Li3AsO4) and iron nitrate (Fe(NO3)3) are dissolved in water. What precipitate would you expect to form? what is the name and formula?
Answer:
CO₃²⁻ + H₂O <----------------> HCO₃⁻ + OH⁻The chemical formula of the precipitate is Fe(OH)₃Explanation:
Fe(NO₃)₃ and K₂CO₃ are strong electrolytes and completely dissociate in water. Carbonate ions is a weak base and combine with water to form hydroxide ions (OH⁻), CO₃²⁻ + H₂O <----------------> HCO₃⁻ + OH⁻ Ferric, Fe (III), combines with these hydroxide ions to form insoluble precipitates. Fe(OH)₃ is only partially soluble i.e., it does not completely dissociate in water. When the solutions of Fe(NO₃)₃ and K₂CO₃ are mixed, Fe(OH)₃ precipitates out due to the strong electrostatic attraction between Fe (III) and hydroxide ions.Two reactant particles collide with proper orientation. The collision will be effective if the particles have
(A) sufficient potential energy
(B) high activation energy
(C) high ionization energy
(D) sufficient kinetic energy
And explain why, and answer in brainly
The collision will be effective if the particles have sufficient kinetic energy (Option D).
Kinetic energy is motion energy, conversely to potential energy.Kinetic energy is required to produce the collision between particles.The more kinetic energy the particles have, then the more collision will occur, thereby it increases the rate of a chemical reaction.In conclusion, the collision will be effective if the particles have sufficient kinetic energy (Option D).

1. The pH of a solution made by combining 150.0 mL of 0.10 M KOH with 50.0 mL of 0.20 M HBr is closest to which of the following?
Answer:
12
Explanation:
The pH of the solution prepared has been 1.25.
The pH of the solution resulting from the mixing of the two solutions can be given by:
Hydrogen ion concentration = [tex]\rm \dfrac{M_1V_1\;-\;M_2V_2}{V_1\;+\;V_2}[/tex]
Where, M1 and M2 have been the molarity of the solution and V1 and V2 have been the volume of the solutions.
For the given resulted solution:
Hydrogen ion concentration = [tex]\rm \dfrac{0.1\;\times\;0.15L\;-\;0.2\;\times\;0.05L}{0.15\;+\;0.05\;L}[/tex]
Hydrogen ion concentration = 0.055 M
pH can be defined as the negative logarithm of hydrogen ion concentration.
pH = - log (Hydrogen ion concentration)
pH = -log (0.055)
pH = 1.25
The pH of the solution prepared has been 1.25.

Determine the freezing point depression of 2 kg of water when 2 mol salt is added to it. The kf of water is 1.86 degrees C/M. Show all your work.
Answer: The freezing point depression is [tex]1.86^0C[/tex]
Explanation:
Depression in freezing point is given by:
[tex]\Delta T_f=K_f\times m[/tex]
[tex]\Delta T_f[/tex] = Depression in freezing point
[tex]K_f[/tex] = freezing point constant = [tex]1.86^0C/m[/tex]
m= molality = [tex]\frac{\text {moles of solute}}{\text {mass of solvent in kg}}=\frac{2mol}{2kg}=1m[/tex]
[tex]\Delta T_f=1.86mol/kg^0C\times 1m[/tex]
[tex]\Delta T_f=1.86^0C[/tex]
Thus freezing point depression is [tex]1.86^0C[/tex]

An unknown amount of Al203 decomposed producing 215 g of solid aluminum. 2Al2O3=4Al+3O2 How many grams of oxygen gas should be produced
Answer:
191.11 grams of oxygen gas should be produced.
Explanation:
The balanced reaction is:
2 Al₂O₃ → 4 Al + 3 O₂
By stoichiometry of the reaction (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:
Al₂O₃: 2 molesAl: 4 molesO₂: 3 molesBeing the molar mass of each compound:
Al₂O₃: 102 g/moleAl: 27 g/moleO₂: 32 g/moleBy reaction stoichiometry, the following mass quantities of each compound participate in the reaction:
Al₂O₃: 2 moles* 102 g/mole= 204 gramsAl: 4 moles* 27 g/mole= 108 gramsO₂: 3 moles* 32 g/mole= 96 gramsThen you can apply the following rule of three: if by stoichiometry 108 grams of aluminum are produced along with 96 grams of oxygen, 215 grams of aluminum are produced along with how much mass of oxygen?
[tex]mass of oxygen=\frac{215 grams of aluminum*96 grams of oxygen}{108grams of aluminum}[/tex]
mass of oxygen= 191.11 grams
191.11 grams of oxygen gas should be produced.
