Explanation:
A sound wave has a frequency of 3250 Hz and a
wavelength of 0.1 m. What is its velocity? SHOW
YOUR WORK
help please!!
Answer:
c = 325.0 m/s.
Explanation:
Hello there!
In this case, since the frequency, velocity and wavelength are related via:
[tex]c=\lambda *f[/tex]
Whereas c is the velocity, lambda the wavelength and f the frequency. Thus, we plug in the given data to obtain:
[tex]c=3250s^{-1}*0.1m\\\\c=325.0m/s[/tex]
Best regards!
. Which of the following statements is false?
a. The actual yield is the amount of product
actually produced by a chemical reaction.
B. The percent yield= actual yield/ theoretical yield (X) 100%
C. The theoretical yield is the amount of product
that can be made based on the amount of
limiting reagent.
d. The limiting reactant is completely consumed in
a chemical reaction.
e. All of the above are true statements.
Answer: A. The actual yield is the amount of product actually produced by a chemical reaction.
The actual yield is the amount of product actually produced by a chemical reaction. This statement is false. Therefore, the correct option is option A.
What is percent yield?Chemists use the calculation percent yield to assess the effectiveness of chemical reactions. Every chemical reaction that they deal with has a predicted outcome. The great majority of the time, even with a desired outcome in mind that should occur chemically, this doesn't actually happen. The percent yield equation gives chemists an indication of how successfully the reaction actually went, as opposed to the best possible outcome they had anticipated.
The percent yield equation is useful for various purposes, such as finances, in addition to helping us understand chemical reactions better. The percent yield metric is used by businesses that produce chemical-based goods to assess their financial health and productivity. The actual yield is the amount of product actually produced by a chemical reaction. This statement is false.
Therefore, the correct option is option A.

Answer:
446 mmHg
Explanation:
From the question given above, the following data were obtained:
Total pressure (Pₜ) = 871 mmHg
Partial pressure of He (Pₐ) = 281 mmHg
Partial pressure of N₂ (P₆) = 144 mmHg
Partial pressure of O₂ (P꜀) =?
The partial pressure of O₂ can be obtained as follow:
Pₜ = Pₐ + P₆ + P꜀
871 = 281 + 144 + P꜀
871 = 425 + P꜀
Collect like terms
P꜀ = 871 – 425
P꜀ = 446 mmHg
Therefore, the partial pressure of O₂ in the mixture is 446 mmHg

Consider the following diagram of a chemical reaction.
A series of four increasingly more complex chemical structures. The first diagram shows that when heat is applied to R single bond O single bond O single bond R, it creates 2 R single bond O with 1 electron dot. The next structure brings in more complex structures and other atoms, such as H and C. This process continues until the final molecule has a long chain of six starting with R O and ending with C with a single electron dot. There are four single side chains, 3 P h and 1 H.

0.25m
3.96M
Heeeellllppppp meeee pls
Answer:
3.96 M
Explanation:
Step 1: Given data
Concentration of the concentrated solution (C₁): 8.9 MVolume of the concentrated solution (V₁): 76 mLConcentration of the diluted solution (C₂): ?Volume of the diluted solution (V₂): 171 mLStep 2: Calculate the concentration of the diluted solution
We can calculate the concentration of the diluted solution using the dilution rule.
C₁ × V₁ = C₂ × V₂
C₂ = C₁ × V₁/V₂
C₂ = 8.9 M × 76 mL/171 mL = 3.96 M

There are 4.67 * 10 ^ 24 hydrogen gas molecules the react with 21.0 Liters of oxygen gas STP conditions to form water. How many grams of water will form? How many moles of the excess reactant will remain after the reaction is completed?
Answer:
I am almost done
Explanation:
21.0 L
↓
2H₂(g) + O₂(g) → 2H₂O(l)
↑
4.67 × 10²⁴ moles
[This is done so the equation is balanced and the reaction can occur]
[subscripts are the number of atoms, and the coefficients are the number of molecules]
______________
Since there are about 6.02 × 10²³ moles in one mol of a substance.
4.67 × 10²⁴ / 6.02 × 10²³ =
7.7547174437 mol.
Next, we must determine the grams per mole of each substance, this can be done with the periodic table.
Since hydrogen, and oxygen gas are diatomic, they will consist of two atoms each. So the atomic mass will be multiplied by 2 to get the molecular mass. Therefore H₂ will have a molecular mass of 1.00794 × 2 = 2.01588 g/mol.

What does the total thermal energy of a system depend on?
Answer:
The correct answer is - temperature, state of molecules, and the number of molecules.
Explanation:
The total thermal energy of a system or the total internal energy of a system solely depends on three major aspects of the system's or objects that are the number of molecules or atoms in the system, the temperature of the system, and the state or arrangement of the molecules of the system. More the molecules or atoms present in a system at a particular temperature higher the total thermal energy the system has.
Thus, the correct answer is - temperature, state of molecules, and the number of molecules.
The generic metal hydroxide M(OH)2 has Ksp = 8.05×10−12. (NOTE: In this particular problem, because of the magnitude of the Ksp and the stoichiometry of the compound, the contribution of OH− from water can be ignored. However, this may not always be the case.)
a) What is the solubility of M(OH)2 in pure water?
b) What is the solubility of M(OH)2 in a 0.202 M solution of M(NO3)2?
Answer:
a. in pure water Solubility (x) = 1.26 x 10⁻⁴M
b. in 0.202M M⁺² Solubility (x) = 9.963 x 10⁻¹²M
The large drop in solubility is consistent with the common ion effect.
Explanation:
a. Solubility in pure water
Given: M(OH)₂ ⇄ M⁺² + 2OH⁻
I --- 0 0
C --- x 2x
E --- x 2x
Ksp = [M⁺²][OH⁻]² = (x)(2x)² = 4x³ => x = CubeRt(Ksp/4)
solubility in pure water = x = CubeRt(8.05 x 10⁻¹²/4) = 1.26 x 10⁻⁴M
b. Solubility in presence of 0.202M M⁺² as common ion.
Given: M(OH)₂ ⇄ M⁺² + 2OH⁻
I --- 0.202M 0
C --- +x +2x
E --- 0.202M + x 2x
≈ 0.202M
Ksp = [M⁺²][2x]² = (0.202)(2x)² = (0.202)(4x²) = 8.05 x 10⁻¹²
=> x = (8.05 x 10⁻¹²)/(0.202)(4) = 9.963 x 10⁻¹²M
