define acidic salt with example
Answer:
[tex] \color{magenta} \huge{ \boxed{answer}}[/tex]
Acidic SaltAcid salts are a class of salts that produce an acidic solution after being dissolved in a solvent. Its formation as a substance has a greater electrical conductivity than that of the pure solvent. An acidic solution formed by acid salt is made during partial neutralization of diprotic or polyprotic acids.

i need a paragraph basically explaining what the carbon cycle is
Answer:
The carbon cycle explains how carbon travels from one reservoir to another on the earth. This cycle is vital for the Earth's atmosphere and carbon balance to remain stable.
Explanation:
Answer:
The carbon cycle describes the process where carbon atoms continually travel from the atmosphere to the Earth and then back into the atmosphere. Since Earth's atmosphere forms a closed environment, the amount of carbon in this system doesn't change.

The density of acetic acid is 1.05 g/mL. What is the volume of 327 g of acetic acid
Answer:
[tex]311.43\ \text{mL}[/tex]
Explanation:
[tex]\rho[/tex] = Density of acetic acid = [tex]1.05\ \text{g/mL}[/tex]
[tex]m[/tex] = Mass of acetic acid = [tex]327\ \text{g}[/tex]
[tex]V[/tex] = Volume
Density is given by
[tex]\rho=\dfrac{m}{V}\\\Rightarrow V=\dfrac{m}{\rho}\\\Rightarrow V=\dfrac{327}{1.05}\\\Rightarrow V=311.43\ \text{mL}[/tex]
The volume of acetic acid is [tex]311.43\ \text{mL}[/tex].

An 85.00 g sample of an unknown compound contains 24.26 g molybdenum, 24.33 g sulfur, and the rest is oxygen. How many moles of molybdenum are present in the compound
Answer:
A) 0.253 mol B) 0.7603 mol C) 2.276 mol D) MoS₃O₉ or Mo(SO₃)₃ E) molybdenum(VI) sulfite
Explanation:
For all the Mole problems you want to find divide grams of the element in compound by the molar mass of the element.
24.26 g Mo / 95.95 g = 0.2528
24.33 g S / 32.06 g = 0.7589 mol S
36.41 g O / 16 g = 2.276 mol O
S / Mo = 0.7587 mol / 0.2529 mol = 3/ 1
O / Mo = 2.276 mol / 0.2529 mol = 9/ 1
The empirical formula of the compound is MoS₃O₉ or Mo(SO₃)₃.
The number of mole of molybdenum present in the compound is 0.253 mole
From the question given above, the following data were obtained:
Mass of compound = 85 g
molybdenum = 24.26 g
Sulphur = 24.33 g
The number of mole of molybdenum in the compound can be obtained as follow:
Mass of molybdenum = 24.26 g
Molar mass of molybdenum = 95.95 g/mol
Mole of molybdenum =?Mole = mass / molar mass
Mole = 24.26 / 95.95
Mole of molybdenum = 0.253 moleTherefore, the number of mole of molybdenum present in the compound is 0.253 mole

A 17.5 ml sample of an acetic acid (ch3co2h) solution required 29.6 ml of 0.250 m naoh for neutralization. the concentration of acetic acid was __________ m.
Answer:
0.423M
Explanation:
The reaction of acetic acid with NaOH is:
CH₃CO₂H + NaOH → CH₃CO₂Na + H₂O
That means the moles of NaOH added = Moles acetic acid in the solution
To solve this problem we need to find the moles of NaOH added to find the moles of acetic acid and its concentration using its volume as follows:
Moles NaOH:
29.6mL = 0.0296L * (0.250mol / L)= 0.0074 moles NaOH = Moles acetic acid
Molarity acetic acid:

How much heat is required to raise the temperature of 10.0 g of iron from 25°C to 100.°C? The specific heat capacity of iron is 0.46 J/g°C.
Answer:
345J
Explanation:
-mass of iron (m) = 10.0 g
-temperature (ΔT) = final temperature- initial temperature= 100-25= 75 degree Celsius
-Specific Heat capacity of iron (c)= 0.46J/g°C.
Heat (Q)=?
Solution:
Formula for Heat is :
Q=m x c x ΔT
Q= 10 x 0.46 x 75
Q= 345 J.
so, 345 joules of heat are needed to increase the temperature of 10 grams of iron.
From the above formula, all other questions can easily be solved from the same procedure.
345 joules of heat is required to raise the temperature of 10.0 g of iron from 25°C to 100°C.
How we calculate the required heat in any reaction?Required heat of any reaction can be calculated as:
Q = m x c x ΔT, where
In the question given that:
m = mass of iron = 10g
c = specific heat capacity of iron = 0.46J/g°C
ΔT = change in temperature = final temperature- initial temperature= 100-25= 75 degree Celsius
Now putting all these values in the above equation, we get
Q= 10g x 0.46J/g°C x 75°C = 345J
Hence, 345 joules of heat is required.

How many moles are needed in a 100. mL solution of a 0.10M CuSO4 5H2O solution?
Answer: The moles needed are 0.01.
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.
[tex]Molarity=\frac{n\times 1000}{V_s}[/tex]
where,
n = moles of solute [tex](CuSO_4.5H_2O)[/tex] = ?
[tex]V_s[/tex] = volume of solution in ml
Now put all the given values in the formula of molarity, we get
[tex]0.10=\frac{n\times 1000}{100}[/tex]
[tex]n=\frac{0.10\times 100}{1000}=0.01[/tex]
Therefore, the moles needed are 0.01.
