Answer:
For 1hour whole milk feed = (60,000 /6 )Kg=10,000Kg
So that the flow rate of whole milk feed = 10,000 kg/hr
Mass of whole milk=10,000 kg
Mass of cream = x kg Mass of skim milk=(1-x) Mass balance equation is Whole milk= skim milk + cream 10,000kg=skim milk + x kg So, skim milk = (10,000-x) kg Material balance on fat is 10,000kg×0.04 = (10,000-x)×0.004 + x On solving the above equation we get the value of x So, x=361.44 kg So that the flow rate of cream = x= 361.44kg/hr and mass of skim milk= (10,000-x)=(10,000-361.44)kg = 9,638.56 kg So that the flow rate of skim milk = 9,638.56 kg/hr. for checking
(Whole milk) flow rate = (skim milk + cream) flow rate
10,000 kg/hr = (9,638.56 + 361.44) kg/hr 10,000 kg/hr = 10,000 kg/hr Hence it is proved.

Which best explains why an Al 3+ ion is smaller than an Al atom?
In forming the Al³+ ion, the Al atom loses the electrons in its outermost energy
level, causing a decrease in the atomic radius.
In forming the Al3+ ion, the Al atom gains three protons and the resulting net
positive charge keeps the electrons more strongly attracted to the nucleus,
reducing the radius.
The Al3+ ion contains more electrons than the Al atom, which results in a greater
attraction for the nucleus and a smaller atomic radius.
In forming the A13+ ion, the Al atom adds electrons into a higher energy level,

Please enter your answer with two sig figs, no units, no scientific notation.
Explain please <3
Answers
The aquarium has 0.35 g of dissolved oxygen in it.
What is mass?The quantity of matter in an object is expressed in terms of mass. It is a scalar number, and units like grams, kilograms, and pounds are used to measure it. Weight, the force of gravity acting on an object, is not the same as mass. An object's mass is a fundamental characteristic that exists regardless of where it is or the gravitational environment it is in.
How do you determine it?Henry's law, which connects the concentration of a gas in a solution to its partial pressure, can be used to determine the mass of oxygen (O2) that would be dissolved in a 40 L aquarium:
C = kH x P
where P is the partial pressure of the gas, kH is the Henry's law constant, and C is the concentration of the gas in the solution.
To solve the concentration by rearranging the equation, we obtain:
C = (kH x P)
Using the above values for kH and P, we obtain:
C = (1.3 10^-3 M/atm) x (0.21 atm) = 2.73 10^-4 M.
This indicates that the aquarium's dissolved oxygen concentration is 2.73 x 10^-4 M.
We can use the following equation to determine the mass of O2 dissolved in the aquarium:
Mass = concentration x volume x molar mass.
where O2 has a molar mass of 32 g/mol.
Inputting the values provided yields:
mass = (2.73 x 10^-4 M) x 40 L x 32 g/mol = 0.35 g
As a result, the aquarium has 0.35 g of dissolved oxygen in it.

a gallon of paint. covers an average of 20.0m^2 of surface. The paint costs $10.00 per gallon. What is the cost of the paint needed to cover a surface that is 108.0ft long by 10.0ft wide?
Answers
Answer:
60 dollars.-
Explanation:
1 meter = 3.28 feet
1 square meter = 3.28^2 feet^2
1 square meter = 10.7584 square feet.
20 square meters = 10.7584 * 20 = 215.168 square feet.
The area to be painted is 108.0 * 10.0 = 1080 square feet
The number of cans of paint needed = 1080/215.168
The number of cans of paint needed = 5.09 cans
Even with so little above 5, you have to round up. So it is 6 cans of paint needed.

Answer:
Does a reaction occur when aqueous solutions of copper(II) nitrate and calcium chloride are combined?
Explanation:
The given reaction is an example of a chemical double displacement reaction.
The mutual interchange of the ions takes place.
The balanced chemical equation of the reaction is:
\(Cu(NO_3)_2(aq)+CaCl_2(aq) -> Ca(NO_3)_2(aq)+CuCl_2(aq)\)
All the products formed are also highly soluble.
So, all the ions are spectator ions.
Hence, all will cancel with each other and ions remain in the net ionic equation and hence, the reaction does not take place.

A sample of 0.49 g of carbon dioxide was obtained by heating 1.22 g of calcium carbonate. What is the percent yield for this reaction
Answers
The percent yield for the reaction of a sample of 0.49 g of carbon dioxide was obtained by heating 1.22 g of calcium carbonate is 92.4%
Given the mass of carbon dioxide (\(CO2\)) = 0.49g
The mass of calcium carbonate (\(CaCO3\)) = 1.22g
The reaction is as follows:
\(CaCO3(s) -- > CaO(s)+CO2(s)\)
As we see 1 mole of CaCO3 is required to produce 1 mole of \(CO2\)
The molar mass of calcium carbonate, = 100.09 g/mol.
The molar mass of given carbon dioxide = 44g
mass of \(CaCO3\) used = number of moles x molar mass = 1 * 100 = 100g
Mass of \(CO2\) produced = 1 * 44 = 44g
Here for 100g of \(CaCO3\) 44g of \(CO2\) is produced.
Then for 1.22g of \(CaCO3\) = 44 * 1.22/100 = 0.53g of \(CO2\) is produced.
But the actual yield of carbon dioxide is 0.49 g
The percent yield is calculated by dividing the actual yield by the theoretical yield and multiplying by 100.

Explanation:
The equilibrium constant for the reaction is 14. The equilibrium will shift towards the product.
What is equilibrium?Equilibrium is defined as a condition in which the forward and backward reaction rates are identical. When all of the external forces acting on an object are balanced, the object is said to be in equilibrium in a reference coordinate system. This indicates that all external forces and moments acting on this item have a net effect of zero.
When sulfur dioxide SO2 concentration is increased, the Q value rises to 1.4.
Q = [ SO₃ ]² / [ SO₂ ]² [ O₂ ]
Q = 1.4
Where K
K = [ SO₃ ]² / [ SO₂ ]² [ O₂ ]
K = 14
Q will shift to the right to consume the extra SO2 and restore the equilibrium position since Q is less than K.

Answers
Answer:
Br-CH2-CH(CH3)2-C(Cl)H-CH(CH3)2-CHO
Explanation:
The molecule has a total of 14 carbon atoms, 13 hydrogen atoms, and 1 bromine atom. The carbon atoms are arranged in a chain with a methyl group attached to the second carbon atom, a chlorine atom attached to the third carbon atom, and two methyl groups attached to the fourth carbon atom. The fifth carbon atom has a carbonyl group attached to it.
The molecule is an aldehyde, which means that it has a carbonyl group (C=O) at the end of the chain. The carbonyl group is polar, and the oxygen atom has a partial negative charge. The hydrogen atom has a partial positive charge. This polarity makes the aldehyde group susceptible to nucleophilic attack.
The bromine and chlorine atoms are both electrophilic, which means that they have a partial positive charge. This makes them susceptible to nucleophilic attack.
The methyl groups are non-polar and do not have any significant reactivity.
The molecule is a chiral molecule, which means that it has a mirror image that is not superimposable on itself. This is because the carbon atom with the carbonyl group is attached to four different groups.
The molecule is a liquid at room temperature and has a strong odor. It is used in a variety of products, including perfumes, flavorings, and plastics.

In this case, since the reaction between silver nitrate and sodium acetate is:
\(AgNO_3(aq)+NaC_2H_3O_2(aq)\rightarrow AgC_2H_3O_2(s)+NaNO_3(aq)\)
In such a way, we can calculate the concentration of silver and acetate ions in the solution as shown below, and considering that the final total volume is 50.00 mL or 0.0500 L:
\([Ag^+]=\frac{20.00mL*0.077M}{50.00mL}=0.0308M\)
\([C_2H_3O_2^-]=\frac{30.00mL*0.043M}{50.00mL}=0.0258M\)
In such a way, we can calculate the precipitation quotient by:
\(Q=[Ag^+][C_2H_3O_2^-]=0.0308*0.0258=7.95x10^{-4}\)
Which is smaller than Ksp and meaning that the precipitation does not occur.
