Answer: Least Common Multiplier of a6m, 0.003 moles 0.01elamos
Steps 6m, 0.003 moles
Compute an expression comprised of Factors that appear either in a6m or 0.003 moles
= 0.018elamos
Explanation:
Taking into account the definition of molarity, 0.005 liters of a 6.0 M solution of acetic acid contain 0.0030 moles.
Definition of molarityMolar concentration or molarity is a measure of the concentration of a solute in a solution and indicates the number of moles of solute that are dissolved in a given volume.
The molarity of a solution is calculated by dividing the moles of solute by the volume of the solution:
[tex]molarity=\frac{number of moles}{volume} [/tex]
Molarity is expressed in units [tex]\frac{moles}{liters} [/tex].
This caseIn this case, you have a 6.0 M solution of acetic acid that contain 0.0030 moles. Replacing in the definition of molarity:
[tex]0.6\frac{moles}{liters} =\frac{0.0030 moles}{volume} [/tex]
Solving:
0.6 [tex]\frac{moles}{liters} [/tex]× volume= 0.0030 moles
volume= 0.0030 moles ÷0.6 [tex]\frac{moles}{liters} [/tex]
volume=0.005 liters
Finally, 0.005 liters of a 6.0 M solution of acetic acid contain 0.0030 moles.

Answer:
it will all fall unless these is air
Explanation:
Answer:
If you do it carefully enough, a small amount of water will pour out of the glass — that's supposed to happen. But try not to let any air bubbles get into the glass. Finally, slowly remove the hand holding the cardboard in place.

Explanation:
A 25.0 L tank of nitrogen gas is at 25 oC and 2.05 atm . If the temperature stays at 25 oC and the volume is decreased to 14.5 L , what is the new pressure?
Answer:
[tex]\boxed {\boxed {\sf P_2 \approx 3.53 \ atm}}[/tex]
Explanation:
In this problem, the temperature stays constant. The volume and pressure change, so we use Boyle's Law. This states that the pressure of a gas is inversely proportional to the volume. The formula is:
[tex]P_1V_1=P_2V_2[/tex]
Now we can substitute any known values into the formula.
Originally, the gas has a volume of 25.0 liters and a pressure of 2.05 atmospheres.
[tex]25.0 \ L * 2.05 \ atm = P_2V_2[/tex]
The volume is decreased to 14.5 liters, but the pressure is unknown.
[tex]25.0 \ L * 2.05 \ atm = P_2 * 14.5 \ L[/tex]
Since we are solving for the new pressure, or P₂, we must isolate the variable. It is being multiplied by 14.5 liters and the inverse of multiplication is division. Divide both sides by 14.5 L .
[tex]\frac {25.0 \ L * 2.05 \ atm }{14.5 \ L}=\frac{P_2 *14.5 \ L}{14.5 \ L}[/tex]
[tex]\frac {25.0 \ L * 2.05 \ atm }{14.5 \ L}= P_2[/tex]
The units of liters cancel.
[tex]\frac {25.0 * 2.05 \ atm }{14.5 }=P_2[/tex]
[tex]\frac {50.25\ atm }{14.5 }=P_2[/tex]
[tex]3.53448276 \ atm = P_2[/tex]
The original values of volume and pressure have 3 significant figures, so our answer must have the same.
For the number we found, that is the hundredth place.
3.53448276The 4 in the thousandth place (in bold above) tells us to leave the 3 in the hundredth place.
[tex]3.53 \ atm \approx P_2[/tex]
The new pressure is approximately 3.53 atmospheres.
Ionic compounds are held together with ionic bonds between ions. The ions are formed when valence electrons are
Answer: Electrovalent bonds are produced when electrons are transferred from atoms of one element to atoms of another element, producing positive and negative ions. The bond which is formed by the transfer of electrons between the atoms is called electrovalent bond or ionic bond. Electrovalent bonds are only formed between metals and non-metals. Electrovalent bonds are not formed between two non-metals.
In simple words electrovalent bond involves the transference of a certain number of electrons to another dissimilar atom which has a tendency to gain electrons so that both acquire stable inert gas configurations. The electrostatic attraction always tends to decrease the potential energy. Hence, the potential energy of the system is much less than it was before the formation of an ionic bond.
Explanation: An Ionic bond is the bond formed by the complete transfer of valence electron to attain stability.
This type of bonding leads to the formation of two oppositely charged ions – positive ion known as cations and negative ions are known as anions.
The presence of two oppositely charged ions results in a strong attractive force between them. This force is an ionic or electrovalent bond.
Ionic bonds form between atoms with large differences in electronegativity, whereas covalent bonds formed between atoms with smaller differences in electronegativity.
The compound formed by the electrostatic attraction of positive and negative ions is called an ionic compound.

What is the pressure if 3 mol of gas has a volume of 2.3 L at 15°C?
Answer:
30.84atm
Explanation:
Using the ideal gas formula:
PV = nRT
Where;
P = pressure (atm)
V = volume (L)
n = number of moles (mol)
R = gas law constant (0.0821Latm/molK)
T = temperature (K)
According to the provided information in this question,
P = ?
V = 2.3 L
n = 3 mol
T = 15°C = 15 + 273 = 288K
Using PV= nRT
P = nRT/V
P = (3 × 0.0821 × 288) ÷ 2.3
P = 70.9344 ÷ 2.3
P = 30.84atm

The gas in a balloon occupies 1.25 L at 298 K. At what temperature in Celsius (C) will the balloon expand to 6.50 L? (Remember to keep the correct place value in your final answer- thousands place)
Answer:
1549.6K
Explanation:
Using Charles law equation;
V1/T1 = V2/T2
Where;
V1 = initial volume (L)
V2 = final volume (L)
T1 = initial temperature (K)
T2 = final temperature (K)
According to the information supplied in this question:
V1 = 1.25 L
V2 = 6.50 L
T1 = 298K
T2 = ?
Using V1/T1 = V2/T2
1.25/298 = 6.5/T2
0.004195 = 6.5/T2
T2 = 6.5 ÷ 0.004195
T2 = 1549.6K
what happened to the weather after mount tambora epurted?
Answer:
The eruption of Mount Tambora eventually reduced the average global temperature by as much as 3 °C.
Explanation:
The Mount Tambora eruption was the largest and most destructive volcanic event in recorded history, expelling as much as 150 cubic km (roughly 36 cubic miles) of ash, pumice, and other rock, and aerosols—including an estimated 60 megatons of sulfur—into the atmosphere. As that material mixed with atmospheric gases, it prevented substantial amounts of sunlight from reaching Earth’s surface, eventually reducing the average global temperature by as much as 3 °C.

What is the approximate total mass of the reactants, and how should it compare with the total mass of the products? Multiple choice question. a. 62 g, which should be less than the total mass of the products b. 62 g, which should equal the total mass of the products c. 372 g, which should be less than the total mass of the products d. 372 g, which should equal the total mass of the products
Answer:
b. 62 g, which should equal the total mass of the products
Explanation:
According to the law of conservation of mass, which states that mass of a substance can neither be created nor destroyed, hence, the mass of the reactants of a reaction must be equal to the mass of the products in that reaction.
As stated in this question, if the total mass of reactants is 62g, then, in accordance to the law of conservation of mass, the total mass of products should also be equal to 62g.

If the pressure of a gas is 1.01 atm and the temperature is 25°C, then if the pressure is increased to 1.10, what is the new temperature?
Answer:
T2 = 51.6°C
Explanation:
Given:
P1 = 1.01 atm
T1 = 25°C + 273 = 298K
P2 = 1.10 atm
T2 = ?
P1/T1 = P2/T2
Solving for T2,
T2 = (P2/P1)T1
= (1.10 atm/1.01 atm)(298K)
= 324.6 K
= 51.6°C
where Tc = Tk - 273

Explanation:Therefore a strong acid will contribute more H+ ions than a weak acid. Therefore, the pH of a strong acid solution will be higher than a weak acid solution.
How much heat do you need to raise the temperature of 300 g of ethanol from 0°C to 20°C?
Answer:
14.6
Explanation:
I just took the test
The amount of heat to raise the temperature is 14.7J.
How do you calculate the heat needed to raise the temperature?The specific heat capacity of a substance is the quantity of heat needed to raise the temperature of a unit quantity of the substance by one degree. Calling the amount of heat added Q, which will cause a change in temperature ∆T to a weight of substance W, at a specific heat of material Cp, then Q = w x Cp x ∆T
By applying the formula, we get
Q = w x Cp x ∆T
Q = 300 * 2.46 * 20/1000
Q = 14.760J
What is heat?
Heat is energy that is transferred from one body to another as the result of a difference in temperature.
