Any type of metal may join with a non-metal, such as carbon, nitrogen, oxygen, sulfur, phosphorus, and selenium, to create ionic compounds.
A chemical compound known as an ionic compound is one that contains ions bound together by the electrostatic forces known as ionic bonding. Despite having both positively and negatively charged ions, or cations and anions, the molecule is generally neutral.
In most cases, ionic compounds are created between metal and nonmetal components. For instance, the ionic compound calcium chloride is made up of the metal calcium (Ca) and the nonmetal chlorine (Cl) (CaCl2).
A nonmetal and a metal can create an ionic bond, which is the attraction between two ions with opposing charges.
Thus, metal are joined with a non-metal, such as carbon, nitrogen, oxygen, sulfur, phosphorus, and selenium, to create ionic compounds.

Answer/Explanation:
Aluminum and oxygen
Fluorine and oxygen
Ionic compounds are formed when any type of metal is combined with a non-metal such as carbon, nitrogen, oxygen, sulfur, phosphorus, and selenium.
(any)metal + nonmetal = ionic compound
10.20 g C6H12O6 x (1 mole C6H12O6 / 180 g C6H12O6) = 0.0567 mole C6H12O6
Then convert grams of water to kilograms of water by dividing by 1000.
355 g / 1000 = .355 Kg of H2O
molality (m) = (0.0567 mole C6H12O6 / .355 Kg of H2O) = 0.160 m
Then plug it in to the formula Δtf = Kfm
Δtf = (-1.86 °C/m) x (0.160 m)
Δtf = -0.298 °C

Methane and ethane demonstrate the law of definite composition and the law of multiple proportions as these both compounds have the exact atoms but in different ratios.
As for methane, it can be seen that every methane molecule contains 4 hydrogen atoms and 1 carbon atom. Where masses of carbon and hydrogen are in ratio - 12 g C / 4 g H -- reduce to 3g C/ 1 g H .
Ethane contains 2 carbon atoms and 6 hydrogen atom and their mass ratio will be - 24 g C / 6 g H -- reduce to 4 g C/ 1 g H .
So both ethane and methane demonstrate the law of definite composition and the law of multiple proportions.
Law of definite composition: The elements which are present in the compound is combined in the same proportion by mass.
Law of multiple proportion: When two or more compounds are formed by the combination of two elements then the mass ratio of one element is combined with the fixed mass of the other element.
In case of methane, it consist of one carbon atoms and four hydrogen atoms implies that has definite composition. In terms of mass, in methane, carbon and hydrogen atoms are combined in a definite ratio i.e. 12 g C/ 4 g H. Thus, methane has definite composition.
Now, carbon and hydrogen combines to give a class i.e. hydrocarbon. In this case, for every constant mass of carbon the ratio of hydrogen will always reduce to 4/3 ratio for the formation of ethane (hydrocarbon). Thus, law of multiple proportion followed.
Similarly, in case of ethane, this compound also consist of exact atoms but in different ratios.
In case of ethane, it consist of two carbon atoms and six hydrogen atoms implies that has definite composition. In terms of mass, in ethane, carbon and hydrogen atoms are combined in a definite ratio i.e. 24 g C/ 6 g H. Thus, methane has definite composition.
Now, carbon and hydrogen combines to give a class i.e. hydrocarbon. In this case, for every constant mass of carbon the ratio of hydrogen will always reduce to a specific ratio for the formation of methane (hydrocarbon). Thus, law of multiple proportion followed.
the salt bridge
c.
the electrolyte solutions
b.
one of the half-cells
d.
the moving electrons
Answer: Option (a) is the correct answer.
Explanation:
In a voltaic cell, salt bridge is used for connecting oxidation and reduction half cells.
The main purpose of using salt bridge in a voltaic cell is that it helps in maintaining electrical neutrality in the internal circuit occurring at anode and cathode of the cell.
Without salt bridge in a voltaic cell there will be imbalance of charges as a result solution in anode compartment will become positively charged whereas solution in cathode compartment will become negatively charged.
Thus, we can conclude that the salt bridge balances charges that may build up as reduction and oxidation occur in a voltaic cell.
