Answer:
A Infiltration
Explanation:
The downward movement of water through pore spaces and other spaces in soil due to gravity is called infiltration.
Infiltration is greatly due to the force of gravity forcing water through pore spaces downward.
The ground water recharge is also impacted by this downward motion of water. In areas where the surface of the soil is covered with concrete, infiltration is not possible. Soil water content is due to the movement of water by infiltration.What is the product(s) in the reaction below?
Answer:
imma go with the answer B
The product in the reaction [tex]\rm Zn + 2HCl \rightarrow[/tex] is [tex]\rm ZnCl_2 + H_2[/tex]. The correct answer is option D.
A reaction is a process that involves the transformation of one or more substances into one or more different substances.
The reaction between zinc (Zn) and hydrochloric acid (HCl) is a classic example of a single displacement reaction. In this reaction, zinc reacts with hydrochloric acid to produce zinc chloride ([tex]\rm ZnCl_2[/tex]) and hydrogen gas ([tex]\rm H_2[/tex]).
The balanced chemical equation for this reaction is:
[tex]\rm Zn(s) + 2HCl(aq) \rightarrow ZnCl_2(aq) + H_2(g)[/tex]
Therefore, the product of the reaction between zinc and hydrochloric acid is zinc chloride ([tex]\rm ZnCl_2[/tex]) and hydrogen gas ([tex]\rm H_2[/tex]). Option D is the correct answer.

How many moles are in 9.07 x 10^23 atoms of sodium chloride?
Answer:
1.5 moles of sodium chloride are present.
Explanation:
Given data:
Number of moles of sodium chloride = ?
Number of atoms of sodium chloride = 9.07×10²³
Solution:
The given problem will solve by using Avogadro number.
It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance. The number 6.022 × 10²³ is called Avogadro number.
1 mole = 6.022 × 10²³ atoms
9.07×10²³ atoms × 1 mol / 6.022 × 10²³ atoms
1.5 moles of sodium chloride are present.
How does the number of molecules in 1 mol of oxygen compare with the number of molecules in 1 mol of nitrogen?
1 mol of oxygen has fewer molecules.
1 mol of oxygen has more molecules.
Each sample has the same number of molecules.
The molecules cannot be compared without knowing the mass.
Answer:
Each sample has the same number of molecules.
Explanation:
Just took the quiz on edge 2021
Taking into account the definition of Avogadro's number, each sample has the same number of molecules.
Avogadro's NumberAvogadro's Number or Avogadro's Constant is called the number of particles that make up a substance (usually atoms or molecules) and that can be found in the amount of one mole of said substance. Its value is 6.023×10²³ particles per mole.
Avogadro's number applies to any substance.
This caseAvogadro's number applies to any substance. This means that the number of molecules in 1 mol of oxygen is equal to the number of molecules in 1 mol of nitrogen.
Finally, the correct answer is the third option: each sample has the same number of molecules.

How many grams are in 3.00 x 10^24 molecules of Zn(C2H3O2)2?
Answer:
Mass = 917.4 g
Explanation:
Given data:
Number of molecules = 3.00 ×10²⁴ molecules
Mass in gram = ?
Solution:
1 mole contain 6.022 × 10²³ molecules
3.00 ×10²⁴ molecules × 1 mol / 6.022 × 10²³ molecules
0.5×10¹ mol
5 mol
Mass in gram:
Mass = number of moles × molar mass
Mass = 5 mol × 183.48 g/mol
Mass = 917.4 g

How much energy is required to melt 2 kg of copper? Use the table below and
this equation: Q = mLfusion
A. 125.6 kJ
B. 9460 kJ
C. 414 kJ
D. 4730 kJ
Answer:
C. 414 kJ
Explanation:
Given parameters:
Mass of copper = 2kg
Unknown:
Amount of energy required to melt the copper = ?
Solution:
To solve this problem, we use:
Q = m L
m is the mass
L is the latent heat of fusion of copper = 207kJ/kg
So;
Q = 2 x 207 = 414kJ
