what mass of calcium chloride will be produced from 3.750 moles of hcl reacting with ca(oh)2
Answer:
208.125g
Explanation:
Given parameters:
Number of moles of HCl = 3.75moles
Unknown:
Mass of CaCl₂ that will be produced = ?
Solution:
The reaction equation is given as:
2HCl + Ca(OH)₂ → CaCl₂ + 2H₂O
Now, to find the mass of CaCl₂, we have to work from the known to the unknown.
The known specie here is the number of moles of HCl;
2 mole of HCl will produce 1 mole of CaCl₂
3.75moles of HCl will produce [tex]\frac{3.75}{2}[/tex] = 1.875moles
The mass of CaCl₂;
Mass of CaCl₂ = number of moles of CaCl₂ x molar mass
Molar mass of CaCl₂ = 40 + 2(35.5) = 111g/mol
Mass of CaCl₂ = 1.875 x 111 = 208.125g

What products will most likely form when a carboxylic acid reacts with an amine at high temperatures, or in the presence of a catalyst
Answer:
An amide and water are the products formed
Explanation:
Here, we want to know the possible products that could be formed from the reaction of a carboxylic acid with an amine.
An anime has the functional group NH2 while for an organic acids, we have COOH.
So essentially we want to know the result of these two functional groups coming together to react.
The reaction between these two will form an amide in conjunction with water.
Take for example;
R-COOH + R’-NH2 ———> R-COHN -R’ + H2O
Where R and R’ may be the same or different alkyl or aryl groups

Carbon dioxide consists of a central carbon atom with an oxygen atom on each side. Draw a model of the molecule formed by putting lines between the atoms to represent bonds so that each atom has the correct number of bonds.
Answer:
O=C=O
Explanation:
PLATO ANSWER
In carbon dioxide (CO₂), bonding occurs through a combination of covalent and double covalent bonds between the carbon atom and the oxygen atoms.
Carbon dioxide is a linear molecule composed of one carbon (C) atom and two oxygen (O) atoms. Each oxygen atom shares a double bond with the central carbon atom, resulting in a stable molecular structure.
Covalent bonding involves the sharing of electrons between atoms to achieve a stable electron configuration. In the case of carbon dioxide, each oxygen atom shares four electrons with the carbon atom, and the carbon atom shares four electrons overall with the two oxygen atoms.

A nuclear power plant is scheduled to undergo a retrofitting. What is the most likely outcome of the change?
The power plant will no longer generate radioactive wastes.
The power plant will recycle the water it uses to cool the reactor.
The power plant will be able to reprocess its used uranium fuel.
The power plant will switch from fission reactions to fusion reactions.
Answer:
It's B
Explanation:
I got it right on edjenuity
The most likely outcome of the retrofitting of a nuclear power plant is that it will be able to reprocess its used uranium fuel. Therefore, option C is correct.
What is nuclear power plant?A nuclear power plant is a facility that generates electricity by harnessing the heat produced by nuclear reactions. At the heart of a nuclear power plant is the reactor, where a controlled chain reaction of nuclear fission occurs.
Reprocessing is a process by which the used nuclear fuel is chemically treated to separate out and recover the unused uranium and plutonium, which can then be reused as fuel. This reduces the amount of radioactive waste produced by the plant and also extends the life of the uranium fuel.
The fission reactions to fusion reactions is not currently a viable option for power generation, and the idea that a retrofitting would eliminate radioactive wastes is unlikely, as nuclear power plants will always produce some amount of radioactive waste.
Thus, option C is correct.

Calculate the standard biological Gibbs free energy for the reaction: pyruvate- + NADH + H+(aq) ---> Lactate- + NAD+ at 309 K given that the standard Gibbs free energy = -65.0 kJ/mol at this temperature. This reaction occurs under conditions of low oxygen supply, such as in muscle cells during strenuous exercise. Note: See Box 7.1 on page 164. The biological standard state has hydrogen ions at 1x10-7 molar instead of 1 M.
Answer:
[tex]-23592.19\ \text{J/mol}[/tex]
Explanation:
T = Temperature = 309 K
[tex]\Delta G^{\circ}[/tex] = Standard Gibbs free energy = -65.0 kJ/mol
R = Gas constant = 8.314 J/mol K
[tex][H^+][/tex] = Biological standard state has hydrogen ions = [tex]10^{-7}\ \text{molar}[/tex]
Reaction quotient is given by
[tex]Q=\dfrac{1}{[H^+]}\\\Rightarrow Q=\dfrac{1}{10^{-7}}\\\Rightarrow Q=10^7[/tex]
Standard biological Gibbs free energy is given by
[tex]\Delta G=\Delta G^{\circ}+RT\ln Q\\\Rightarrow \Delta G=-65000+8.314\times 309\times \ln10^7\\\Rightarrow \Delta G=-23592.19\ \text{J/mol}[/tex]
The standard biological Gibbs free energy of the reaction is [tex]-23592.19\ \text{J/mol}[/tex]

What mass of solute should you measure out in order to make 1,000 mL of a 0.3 M solution of magnesium phosphate Mg3(PO4)2?
Hey there !
Molecular Weight: 262.86 g/mol
Volume in liters : 1,000 mL => 1,000 / 1000 => 1 L
Number of moles of solution :
number of moles = volume x molarity
number of moles = 1 x 0.3 => 0.3 moles
Therefore:
1 mole Mg₃(PO₄)₂ ------------------- 262.86 g
0.3 moles ----------------------------- mass of Mg₃(PO₄)₂ ??
mass of Mg₃(PO₄)₂ = 0.3 x 262.86 / 1
mass of Mg(PO₄)₂ => 78.858 g

Help plz! Complete the following combustion reaction. Write your balanced equation two different
ways. (1 point)
C3H18 + O2 >
C3H18 + O2 >
Answer:
C₃H₈ + 5 O₂ ⇒ 3 CO₂ + 4 H₂O
2 C₃H₈ + 10 O₂ ⇒ 6 CO₂ + 8 H₂O
Explanation:
The combustion reaction is when propane reacts to oxygen to form a compound of carbon and water. If the product of carbon is carbon dioxide, the combustion is called complete. Let's considered the unbalanced combustion reaction.
(Note: I assume is C₃H₈, propane, because C₃H₁₈ doesn´t exist).
C₃H₈ + O₂ ⇒ CO₂ + H₂O
We will start balancing C and H that are just in 1 compound on each side, and finally we will balance O atoms. One way to do so is:
C₃H₈ + 5 O₂ ⇒ 3 CO₂ + 4 H₂O
We can get a different way of balancing the equation if we, for instance, multiply all the stoichiometric coefficients by 2.
2 C₃H₈ + 10 O₂ ⇒ 6 CO₂ + 8 H₂O

In which Colorado Rockies scenario was there more erosion? Why was there more erosion in the scenario?
Answer:
There was more erosion in the Colorado Rockies scenario where there was steady rain compared to the scenario in the same area where there was only a drizzle. There is more erosion because the steady rain increased the volume of the river more than the drizzle did. Because there was more water added to the river, the river flowed faster. The faster a river flows, the more sediments it transports or erodes.
Explanation:
Edge
There was greater erosion inside the Colorado Rockies situation when there was persistent rain.
What is erosion?Erosion is the loss of soil or rock from the Earth's crust's surface, as well as the movement of the removed material by natural forces (such as wind or water). The term "erosion" is used in its broadest sense to refer to the overall thinning and moulding of all landmasses on the surface of the planet, such as the corrosion of rock in its natural position, the vehicles and public of weathered material, as well as erosion brought on by wind action, marine, as well as glacial processes.
In contrast to the situation within the identical region where there was simply a drizzle, there was greater erosion inside the Colorado Rockies situation when there was persistent rain. Because the volume of a river was raised by the constant rain more than by the drizzle, there is more erosion. The river flowed more quickly as a result of the additional water. A river transfers or erodes more material the quicker it runs.
Therefore, there was greater erosion inside the Colorado Rockies situation when there was persistent rain.
