Answer:
None of the conditions will favor either the forward reaction or backward reaction , hence the answer is D
Explanation:
- The principle of chemical Equilibrium is applied here, where the concentration of the reactants or the forward reaction is same as the concentration of the products or the backward reaction.
- The equilibrium constants is also involved here, K can be in terms of pressure (Kp) or concentration (Kc) hence equilibrium constant is the ration of the concentration of the products to the concentration of the reactants raised to the power of the coefficient of the reactants and products.
- Partial pressure , total pressure and the mole fraction relationship is also applied
- The step by step explanation is as shown in the attachment below.
Answer : Group 14 elements are likely to have substances that have both metal and non-metallic properties.
Explanation :
Metalloid : It is a type of element whose properties lies in between the metals and non-metals.
There are commonly six metalloids : Boron(group 13), Silicon & Germanium(group 14), Arsenic & Antimony(group 15), Tellurium(group 16).
Properties of Metalloids :
- Metalloids look like metals but behave largely like non-metals.
- Metalloids are solid, brittle and lustrous.
- Metalloids has ability to conduct electricity.
Therefore, Group 14 elements are likely to have substances that have both metal and non-metallic properties.
Sulfur DIOXIDE is a covalent compound with various ionic properties. Hope this helps
Answer:
mL sugar sold needed = 2.2215 mL sugar
Explanation:
mass sugar = 7.57 g
∴ wt% = 5% = (g sugar/g sln)×100
⇒ 0.05 = g sugar/g sln
∴ g sln = 100 g
⇒ g sugar = 5 g
∴ δ sugar = 1.157 g/mL
⇒ mL sugar = (5 g)×(mL/1.157 g) = 4.322 mL
⇒ mL sugar needed = (7.57 g)/(1.157 g/mL) = 6.543 mL
mL of the sugar sold needed = 6.543 mL - 4.322 mL = 2.2215 mL sugar
The answer to this question would be: C) a single replacement reaction
In single replacement reaction the molecule made in just one with an element. In this case, the compound is just swapping its element with a more reactive one, results in a more stable compound.
Contrast to the single replacement reaction, double replacement reaction or metathesis is the reaction which results in two new compounds. The cation from the molecule reaction is switching with the cation from other molecules.
In contrast to the double replacement reaction,
