Answer:
The collision of oceanic plates and any other plates in which the oceanic plate slides beneath the other plate creates the biggest earth quakes. Most of these earth quakes occur beneath the sea or oceans and can cause volcanic eruptions as well. Tsunami is another oceanic event that occurs due to earth quakes occurring due to shifting of plates beneath the sea.
what’s another term for weak solutions
If u mean in terms of concentration, it will be 'Dilute'
One that is almost or entirely ionized in water is considered to be a strong acid or alkali. Nitric acid, sulfuric acid, and hydrochloric acid are a few examples. Weak solutions are not ionized in water.
What is a weak solution ?Bases provide a similar problem: a strong base is one that is completely ionized in solution. A weak base is one that is less than 100% ionized in solution.
The fundamental elements that do not completely ionize in water are known as weak bases. Ammonia is one substance that is a weak base. A portion of NH3 that dissolves in water separates into ammonium cation.
An acid that partially separates into its ions in water or an aqueous solution is referred to as a weak acid. On the other hand, in water, a strong acid completely dissociates into its ions. While the conjugate acid of a weak base is also a weak acid, the conjugate base of a weak acid is also a weak solution.
Thus, Weak solutions are not ionized in water.

Answer:
H2SO4 cannot be used with CaCO3 to produce CO2 gas
Explanation:
Because it does not dissolve in water- it forms a barrier on the surface of the unreacted CaCO3 which prevents any further reaction. A small volume CO2 is produced, this stops in short time.

6. El oxígeno gaseoso se calienta a presión constate de 50 °C a 300 K. Se conoce que inicialmente el volumen del sistema era de 1,3 litros. ¿Cuál es el volumen final del sistema?
Answer:
El volumen final del sistema es 1.2L
Explanation:
La ley de Charles establece que el incremento de la temperatura de un gas produce un incremento en el volumen directamente proporcional cuando la presión permanece constante. La ecuación es:
V₁/T₁ = V₂/T₂
Donde V es volumen y T temperatura absoluta de un gas en 1, el estado inicial y 2, su estado final.
Reemplazando:
V₁ = 1.3L
T₁ = 50°C + 273.15K = 323.15K
V₂ = Incógnita
T₂ = 300K
1.3L/323.15K = V₂/300K
1.2L = V₂

What category of organisms makes up the largest percent of the the fossils discovered? A. Land animals B. Marine animals C. Microorganisms
Answer:
Marine animals
Explanation:
A fossil is any remains of ancient life. Fossils can be body fossils, which are remains of the organism itself or trace fossils, such as burrows, tracks, or other evidence of activity(Lumen Learning).
Fossils of land animals are less common because they may not have been buried. However, land organisms may become buried underneath by mudslides or ash from a volcanic eruption, or covered by sand in a sandstorm.
Marine fossils are more common owing to quick burial. Marine animals that die near a river delta may be buried by sediment carried by the river. A storm at sea may shift sediment on the ocean floor, covering and helping to preserve skeletal remains(Lumen Learning).
mass-mass problem:
If 25.0 grams of carbon dioxide are used in photosynthesis how many grams of glucose (C6H12O6) could be Produced according
to the following equation : 6CO2 + 6H2O → C6H12O6 + 602
Answer:
17.05 g of glucose
Explanation:
The equation of the reaction is given as;
6CO2 + 6H2O → C6H12O6 + 602
From the equation;
6 mol of CO2 produces 1 mol of C6H12O6
Converting to masses;
CO2:
Mass =Number of moles * Molar mass
Mass = 6 mol * 44 g/mol = 264 g
C6H12O6:
Mass = Number of moles * Molar mass
Mass = 1 mol * 180 g/mol = 180 g
This means 264g of CO2 produces 180g of C6H12O6
25g of CO2 would produce x g of C6H12O6
264 = 180
25 = x
x = 25 * 180 / 264
x = 17.05 g
5. A boat travels 325,000 meters in 800 seconds. What was its speed?
Answer:
406m/s
Explanation:
Speed = distance ÷ time
Answer:
406 m/s
Explanation:
Divide 325,000 meters by 800 and 800 seconds by 800 (because we are trying to find the speed in meters per second.
325,000÷800 = 406.25 meters
800÷800 = 1 second
≈ 406 m/s

What property allows objects to be subject to gravity?
friction
mass
inertia
acceleration
Answer: i gotcu the answer is mass
Explanation: The more weight of the object the more its subject to gravity like a feather barley is while a bowling ball smashes into the ground :D
The property allows objects to be subject to gravity is mass. Therefore, option B is correct.
What is mass ?Mass is a physical body's total amount of matter. Inertia, or the body's resistance to acceleration when a net force is applied, is also measured by this term.
The strength of an object's gravitational attraction to other bodies is also influenced by its mass. The kilogram serves as the SI's fundamental mass unit. The amount of matter object present is also known as mass.
The amount of matter that makes up every item or body is the greatest way to understand mass. Everything that we can see has mass. Examples of objects with mass include a table, a chair, your bed, a football, a glass, and even air. The mass of a thing determines whether it is light or heavy.
Thus, option B is correct.

how many atoms of alumminum are in 3.9 mol of aluminum
Answer:
2.35 x 10²⁴ atoms Al
Explanation:
Given 3.9 moles of aluminum (Al), determine number of aluminum atoms in that quantity of substance.
By definition a mole is the mass of substance containing one Avogadro's Number (N₀) of particles. That is, 1 mole = 1 N₀ = 6.023 x 10²³ particles*.
So, if 1 mole aluminum contains 6.023 x 10²³ atoms of aluminum then
3.9 moles Al = 3.9 moles Al x 6.023 x 10²³ atoms Al/mole Al = 2.35 x 10²⁴ atoms Al.
________________
*The complete equivalent relationship is ...
1 mole (atoms or compounds) = 6.023 x 10²³ atoms or molecules = 1 formula weight of the substance = 22.4 Liters (if in gas phase at STP conditions (0°C and 1atm pressure).

The F1-ion is classified as a(n).
and has:
A.anion, 1 valence electron
B.anion, 8 valence electrons
C.cation, 2 valence electrons
D.cation, O valence electrons
Answer:
B
Explanation:
The [tex]\rm \bold{F^1^-}[/tex] is the fluorine anion with 8 valence electrons. Hence, option B is correct.
An ion is defined as the atom with the change in the valence electrons by the loss or gain of electrons to complete the outer shell.
What type of ion is [tex]\rm F^1^-[/tex]?The ions with the gain of electrons result in a negative charge and are termed anions. The ions with a loss of electrons have a positive charge and are termed cations.
The F is the halogen atom of group 17 with 7 valence electrons. The ion formed for F requires 1 electron to complete its valence shell.
The ion [tex]\rm F^1^-[/tex] has a negative charge, which denotes it gains an electron and forms anion.
The gain of electrons results in the number of valence electrons being 8.
Thus, [tex]\rm F^1^-[/tex] is the fluorine anion with 8 valence electrons. Hence, option B is correct.
