Answer:
V = 5000 mL
Explanation:
¡Hola!
En este caso, dado que la molaridad de una solution se calcula al dividir las moles por el volume de solución en litros, es posible calcular el volumen cuando se dividen las moles por la molaridad, tal y como se muestra a continuación:
[tex]M=\frac{n}{V}\\\\V=\frac{n}{M}[/tex]
Así, podemos reemplazar la molaridad y moles dadas para obtener:
[tex]V=\frac{1.5mol}{0.3mol/L}=5L[/tex]
Que en mililitros sería:
[tex]V=5L*\frac{1000mL}{1L}\\\\V=5000mL[/tex]
¡Saludos!

Answer:
A. the sun is the smallest object in our solar system
Explanation:
In 2009, the Hubble Space Telescope discovered the smallest object ever seen in visible light at the time within the Kuiper Belt. The Kuiper Belt Object (KBO) found was a mere 3,200 feet (975 meters) across and was 4.2 billion miles away.
What happens to sediments that get deposited in basins?
Sedimentary basins are regions of the Earth where long-term subsidence creates accommodation space for accumulation of sediments. As the sediments are buried, they are subject to increasing pressure and begin the processes of compaction and lithification that transform them into sedimentary rock.

how humans can improve the negative aspects of soil use FULL SENTENCES 50 POINTS PLEASE HELP
Answer:
Using diverse nutrient sources can help maintain soil health. Manure and compost add organic matter as well as an array of nutrients, but using just compost or manure to meet the nitrogen needs of the crop every year can result in excessive phosphorus levels in the soil.
A sample of unknown gas has a temperature of 378k. When the temperature is increased to 546k,the volume also increases to 1047 ml. What was the original volume ?
Given :
A sample of unknown gas has a temperature of 378 K.
[tex]T_i = 378 \ K , \ T_f = 546 \ K[/tex]
When the temperature is increased to 546 K, the volume also increases to 1047 ml.
[tex]V_f - V_i = 1047 \ ml[/tex]
Solution :
We know, temperature is directly proportional to volume.
[tex]\dfrac{T_i}{T_f}=\dfrac{V_i}{V_f}\\\\\dfrac{T_i}{T_f} = \dfrac{V_i}{1047 + V_i}\\\\\dfrac{V_i}{1047+V_i}=\dfrac{378}{546}\\\\546V_i = 378V_i + 378\times 1047\\\\168V_i = 3,95,766\\\\V_i = 2,355.75\ ml[/tex]
Therefore, the original volume is 2.355.75 ml.
What causes the release of energy in an exothermic reaction? Bonds breaking Bonds breaking A catalyst A catalyst Bonds being formed Bonds being formed Electrons escaping the bond
Answer:
weak bonds break and strong bonds form
Explanation:
An exothermic reaction is a chemical reaction in which heat energy is evolved during the reaction process.
Bond formation requires energy while bond breakage releases energy. More energy is needed for the formation of weak bonds as compared to strong bonds.
Hence, when weak bonds break, they release more energy than needed to make a corresponding strong bond leading to the release of the remaining energy as heat.

What does the little 2 in 2CO2 mean?
Answer:
it means 2 oxygen atoms in the molecule
Explanation:
Balance the following chemical equation:
C2H60+02 → CO2 + H20
Answer:
Explain: In order to balance the chemical equation, you need to make sure the number of atoms of each element on the reactant side is equal to the number of atoms of each element on the product side. In order make both sides equal, you will need to multiply the number of atoms in each element until both sides are equal.

How many grams of glycerine, C3H8O3, are needed to make 100. mL of 2.60 M solution?
Answer:
the mass of the glycerine needed in the given solution is 23.92 g
Explanation:
Given;
molarity of the solution (C₃H₈O₃), C = 2.60 M
Volume of the solution, V = 100 mL = 100 x 10⁻³ L = 0.1 M
The molarity of a solution is given as follows;
[tex]Molarity = \frac{amount \ of \ solute \ (moles)}{volume \ of \ solution \ (L)} \\\\amount \ of \ solute \ (moles) = Molarity \ \times volume \ of \ solution \ (L)\\\\amount \ of \ solute \ (moles) = 2.6 \times 0.1 \\\\amount \ of \ solute \ (moles) = 0.26 \ mole[/tex]
The molecular mass of the given solution;
molecular mass = (12 x 3) + (8 x 1) + (16 x 3)
molecular mass = 92 g/mol
The mass of the glycerine needed in the given solution is calculated as follows;
reacting mass = amount of solute (moles) x molecular mass (g/mol)
reacting mass = 0.26 x 92
reacting mass = 23.92 g
Therefore, the mass of the glycerine needed in the given solution is 23.92 g

A. Lithium
B. Helium
C. Oganesson
D. Francium?
Answer:
It's D. Francium
Explanation:
Atomic radii vary in a predictable way across the periodic table. The atomic radius increases from top to bottom in a group and decreases from left to right across a period. Thus, Helium is the smallest element, and Francium is the largest.

A projectile is projected with an initial velocity of 40 m/s at a 45o angle to the horizontal. , calculate the total time travelled.
Answer:
5.77 s
Explanation:
From the question,
The total time travelled by the projectile = Time of flight (T)
T = 2usinθ/g............ Equation 1
Where T = Time of Flight of the projectile, u = Initial velocity, θ = Angle of projection to the horizontal, g = acceleration due to gravity
Given: u = 40 m/s, θ = 45°
Constant: g = 9.8 m/s²
Substitute these values into equation 1
T = 2(40)sin(45°)/9.8
T = 80sin(45°)/9.8
T = 80×0.7071/9.8
T = 5.77 s
A solid substance turns directly into a gas. Which term describes this change?
A)deposition
B)evaporation
C)melting
D)sublimation
Given what we know, we can confirm that the correct term to describe the change from a solid into a gas is sublimation.
What is sublimation?Sublimation is the change from a solid-state into a gas state.Most of the time one will first observe the change into a liquid state, however, with sublimation, the change is directly from the solid into the gas, such is the case with dry ice. Dry Ice is frozen carbon dioxide, as it thaws, it changes directly into its gaseous state.Therefore, we can confirm that sublimation describes the process by which an element passes from a solid directly into a gas, without first becoming a liquid.
