Explanation:There are two main types of mixtures, homogeneous mixtures and heterogeneous mixtures. The components of a homogeneous mixture are evenly distributed throughout the mixture. The properties of a mixture are the same everywhere. The components of a heterogeneous mixture are not evenly distributed. Different regions of this mixture have different properties.
Particles in a homogeneous mixture do not settle down or separate when left alone. Particles in a heterogeneous mixture eventually separate or settle when left alone.
Colloids are a type of heterogeneous mixture that do not naturally settle out quickly, and can be separated with different methods. A suspension is another type of heterogeneous mixtures in which the components of the mixture will quickly settle out or can be filtered or separated.Here are photos of Edge just incase.

What is the molecular formula for a compound that is 34.31% sodium, 17.93% carbon, 47.76% oxygen and has a molar mass of 134.00g?
Answers
Answer: Na2C2O4 probably sodium oxalate
Explanation: assume you have 100 g substance.
Mass of Na is m(Na) = 34.31 g, m(C) = 17.93 g and m(O) = 47.76 g.
Calculate moles n(Na) = 34.31 g/22.99 g/mol= 1.49 mol.
For C n(C) = 1.49 mol and n(O) = 2.985. You divide all by 1.49 you
Get n(Na) : n(C) : n(O) = 1:1:2 M(NaCO2) = 67 g/mol.
Divide 134:67 = 2. You get formula Na2C2O4

If 0.25 moles of KBr is dissolved in 0.5 liters of
heavy water which has a mass of 1,100 grams
per liter, what is the concentration?
Answer in units of m (molal).
Answers
Answer:
[KBr] = 454.5 m
Explanation:
m is a sort of concentration that indicates the moles of solute which are contianed in 1kg of solvent.
In this case, the moles of solute are 0.25 moles.
Let's determine the mass of solvent in kg.
Density of heavy water, solvent, is 1.1 g/L and our volume is 0.5L.
1.1 g = mass of solvent / 0.5L, according to density.
mass of solvent = 0.5L . 1.1g/L = 0.55 g
We convert the mass to kg → 0.55 g . 1kg /1000g = 5.5×10⁻⁴ kg
m = mol/kg → 0.25 mol /5.5×10⁻⁴ kg = 454.5 m
Calculate the specific heat of the substance if 373 J is required to raise the temperature of a 312 gram sample by 25°C?
Answers
Explanation:
Q = 373J
∆∅ = 25°C
m = 312g
c = x
Q = mc∆∅
373 = 312(x)(25)
373 = 7800x
x = 373/7800
x = 0.0478J/(g°C)
The specific heat of the substance if 373 J is required to raise teh temperature of a 312 gram sample by 25°C is 0.0478 J/g
What is specific heat?The amount of energy needed to raise the temperature of one gram of a substance by one degree Celsius.
By the formula of specific heat
Q = mc∆∅
Q = 373J
m = 312g
∆∅ = 25° C
Putting the values in the equation
[tex]373 = 312\times c \times (25)\\\\373 = 7800c\\c= \dfrac{373}{7800} = 0.0478J/(g \circ C)[/tex]
Thus, the specific heat of the substance if 373 J is required to raise teh temperature of a 312 gram sample by 25°C is 0.0478 J/g

A 25.2 mL sample of phosphoric acid was titrated with 32.0 mL
of 0.550 M NaOH solution. What is the concentration of the
sample given the acid-base reaction shown below?
H3PO4 + 3NaOH = Na3PO4 + 3H2O
M
Answers
Answer: 0.233 M
Explanation: (0.550 M)(0.0320 L)= 17.6e-3 mol NaOH
3:1 ratio of NaOH to H3PO4 so divide the moles of NaOH (17.6e-3) by 3. You will get 5.86e-3.
Finally, divide this number (the moles of H3PO4) by the volume (0.252 L) to get 0.233 M
The concentration of given acid base reaction will be 0.226 M
What is Acid base reaction?The chemical reactions that take place when acids and bases are combined together are known as acid-base reactions. Acids and bases are discussed in terms of hydrogen ion exchange in the Bronsted-Lowry hypothesis. A conjugate acid as well as a conjugate base are the end products of such a reaction.
The given acid base reaction is :
H3PO4 + 3NaOH = Na3PO4 + 3H2O.
It can be seen that 3 moles of NaOH give one moles of Na3PO4.
Moles of NaOH = 0.550 M/ 0.0320 L = 17.18
So, by divide the moles of NaOH = 17.18 /3 = 5.72
The given volume = 25.2 mL = 0.252 L
Concentration of acid base reaction = n / v
where, n = moles of solute , v = liters of solution.
Now, put the value of given data in above concentration of acid base reaction formula.
Concentration of acid base reaction = 5.72 / 0.252 L = 22 .69
Therefore, the concentration of acid base reaction will be 0.226M.
