The solubility of ZnCO3 in water is quite low. What could you add to increase the solubility? Explain fully how your method would work.
There is a way to decrease the concentration of an ion here. The carbonate ion happens to be easy to decrease. All we have to do is add some acid (say HCl) to the container. The following sequence of reactions explains how this WO r ks.
As long as more acid is added, this process will continue until all the solid Zn CO3 has been dissolved
The murder weapon weighs 150 grams. The initial temperature of the weapon before being tested was 100 oC. After placing the weapon in the water, the temperature dropped to 25.13 oC. Find the specific heat capacity of the unknown metal by first calculating the heat energy gained by the water.
Water
Mass = 2500 g
Initial temperature = 25 o C Final temperature = 25.13 oC
Equations
q = m C p Δ T C p = q / (mΔT)
1. How much heat energy (q) did the water gain?
2. What is the specific heat capacity (C p) of the unknown metal?
3. Compare the heat capacity you calculated with the one below, which one matches?
Specific heat capacity of metal (J / g or C)
Silver 0.235
Gold 0.129 Lead 0.121
Copper
4. What metal was the murder weapon made of?
0.385
1. heat gained : 1358.5 J
2. Cp metal = 0.121 J/g C
3/4 The metal = Lead
Further explanationThe law of conservation of energy can be applied to heat changes, i.e. the heat received/absorbed is the same as the heat released
Q in = Q out
Heat can be calculated using the formula:
Q = mc∆T
Q water(gained) = Q metal (lost)
1. Heat of water gained
[tex]\tt Q=2500\times 4.18\times (25.13-25)=1358.5~J[/tex]
2. The specific heat capacity (C p) of the unknown metal :
[tex]\tt Cp=\dfrac{1358.5}{150\times (100-25.13)}=0.121~J/g^oC[/tex]
According to Le Chatelier's principle, what happens to the equilibrium constant (K) when the concentration of the reactants is doubled? The value of the equilibrium constant (K) is doubled. The value of the equilibrium constant (K) is halved. The value of the equilibrium constant (K) remains the same. The value of the equilibrium constant (K) changes unpredictably.
Answer:
The value of the equilibrium constant (K) remains the same.
Explanation:
A state of dynamic equilibrium is said to have been achieved in a reaction system when the rate of forward reaction equals the rate of reverse reaction.
At equilibrium, doubling the initial concentration of reactants have no effect on the equilibrium constant K. The equilibrium will rather shift to the left or right as required in order to annul the constraint.

Answer:
What is the question?
Explanation:
What of these should Hailey include in her list?
Synthetic polymers are biodegradable.
Synthetic polymers are not flexible.
Synthetic polymers are recycled cheaply.
Synthetic polymers are inexpensive to produce.
Answer:
Hailey should add, they are inexpensive to produce.
Explanation:
Reason being why they are inexpensive to produce, is due to them being chemical based and easy to product in the factory setting. Which makes them extremely cheap to make.
Reason being why the others are wrong, synthetic polymers are not biodegradable as they are made in a factory with oils. Synthetic polymers are not flexible due to them being used for harder products. Synthetic polymers are not recycled cheaply as they are made with chemicals which makes it very hard to recycle.

What is the similarity between teeth and eggshells?
Explanation:
Because they share a similar composition, similar chemicals affect their structures in positive or negative ways. For example, fluoride – a staple in many dental practices – strengthens both enamel and eggshells and helps protect them from acids. Acids weaken and break down both substances. Scientists find this particularly concerning given that the ocean is growing increasingly acidic. They fear this may weaken the eggs of some marine species and harm their chance of survival. Most dentists recommend limiting aggressively acidic foods and beverages such as soft drinks.
If molten sodium chloride is split by electrolysis, which reaction occurs at the anode?
2Cl2 (g) →2Cl− (l) + 2e−
2Cl− (l) →Cl2 (g) + 2e−
2Na (l) →2Na+ (l) + 2e−
2Na+ (l) + 2e−→2Na (l)
Answer: [tex]2Cl^-(l)\rightarrow 2e^-+Cl_2(g)[/tex]
Explanation:
Electrolysis of a subastance is breaking it into its constituents by the action of electrical current.
In the electrolysis of molten sodium chloride, sodium metal is produced at the cathode which is a negative electrode and chlorine gas produces as the anode which is a positive electrode.
[tex]2NaCl(l)\rightarrow 2Na^++2Cl^-[/tex]
At anode : [tex]2Cl^-(l)\rightarrow 2e^-+Cl_2(g)[/tex]
At cathode : [tex]2Na^+(l)+2e^-\rightarrow 2Na(l)[/tex]
2Cl- (l) → Cl2 (g) + 2e-
what hypothesis is best for chemical reaction?
will give Brainliest
Answer:
If the reactants in the chemical reactions are known, then the products can be predicted because the pattern of the chemical reactions is being followed. The pattern for a single replacement is A + BC --> AC + B. This is like the Hear It Pop Chemical Reaction which is also an example of the single replacement.

bigger size elements have low ionization energy and high shielding effect .justify the statement
Bigger size elements have low ionization energy and high shielding effect because:
Shielding effect:This effect describes the decrease in attraction between an electron and the nucleus in any atom with more than one electron shell. The more electron shells there are, the greater the shielding effect experienced by the outermost electrons.When shielding effect decreases the attraction force exerted by the nucleus increases on valence electrons.As a result, atoms will be larger.Find more information about Shielding effect here:

It requires energy to melt ice. Applying salt to the ice created a chemical reaction melting the ice. Were did the energy come from to melt the ice? *
Answer:
HOPE IT HELPS...
Explanation:
When added to ice, salt first dissolves in the film of liquid water that is always present on the surface, thereby lowering its freezing point below the ices temperature. Ice in contact with salty water therefore melts, creating more liquid water, which dissolves more salt, thereby causing more ice to melt, and so on
Determine the number of moles in a sample of calcium that contains 6.34 x 1022
atoms.
Answer:
0.105 molesExplanation:
To find the number of moles in a substance given it's number of entities we use the formula
[tex]n = \frac{N}{L} \\[/tex]
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
[tex]n = \frac{6.34 \times {10}^{22} }{6.02 \times {10}^{23} } \\ = 0.105315...[/tex]
We have the final answer as
0.105 molesHope this helps you
does SiF4 have polar covalent bonds?
Answer:
SiF4 is not a polar covalent bond.
Explanation:
SiF4 is a nonpolar molecule because the fluorine's are arranged around the central silicon atom in a tetrahedral molecule with all of the regions of negative charge cancelling each other out.

Which sample contains the same number of atoms as a gram-atomic mass of He?
1.
6 g of C
2.
7 g of Li
3.
8 g of o
4.
9 g of F
Submit Answer
Answer: 2. 7g of Li
Explanation: A mole of any substance contains the same number of particles (Avogadro's number, 6.02*10^23). 1 gram atomic mass of He (4g) is equivalent to 1 mole; so is 1 gram atomic mass (7g) of Li

How does knowing the meaning of prefix-trans help you remember what happens to light that strikes a translucent object ?
Explanation:
The prefix trans- and its variant tra- mean "across".
A translucent substance allows some light to go "across" it to the other side. Also, think about a transparent substance: it allows light to go "across" it; or a translation, it is a going "across" from one language into another.
