Answer: The correct answer is option a.
Explanation: Binary ionic compounds are the compounds made up of two ions, one is cation which is metal and another is anion which is a non-metal.
Rules for the naming of Binary Ionic compound.
1. First write the full name of cation.
2. The anion is named after using the suffix '-ide'. For example: If the anion is bromine, the name will be bromide and so on.
3. If the metal atom is Transition element, then the roman numeral is included after the metal name to indicate the oxidation number of the metal.
So, in order to write the name of Binary Ionic Compound, we first write metal followed by non-metal. Hence, the correct option is option a.
Answer:
a. Combustion.
b. 
c. 
Explanation:
Hello.
a. In this case, given the reaction by which propane is converted into carbon dioxide and water:
It is known as a combustion reaction since it is about a fuel (here propane) which is burnt by the oxygen contained in the air (21%).
b. Since the carbon dioxide contains all the carbon in the products based on the law of conservation of mass, the yielded grams are computed via a mole mass relationship:
Since 44 grams of carbon dioxide contain 12 grams of carbon.
c. As well as b., all the hydrogen is given off in form of water, thus, the required mass turns out:
Since 18 grams of water contain 2 grams of hydrogen.
Best regards.

<span>A characteristic feature of diatom cells is that they are encased within a unique cell wall made of silica (hydrated silicon dioxide) called a frustule.</span>
It can only do that when one of the components of the mixture is a magnetic
material.
When you have that situation, you pass the magnet over the mixture ... shaking
the mixture if it's a dry mixture of powders or pieces ... and the magnetic part of
the mixture moves toward the magnet, while the nonmagnetic parts of the mixture
couldn't care less about the magnet and they just stay where they are.
