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:
C. 0.4.
Explanation:
<em>∵ mole fraction of acetic acid (X acetic acid) = (no. of moles acetic acid)/(total no. of moles) = (no. of moles acetic acid)/(no. of moles of acetic acid + no. of moles of water).</em>
<em></em>
- no. of moles of acetic acid = 2, no. of moles of water = 3.
- Total no. of moles = no. of moles of acetic acid + no. of moles of water = 2 + 3 = 5.
<em>∴ mole fraction of acetic acid (X acetic acid) = (no. of moles acetic acid)/(total no. of moles) =</em> (2)/(5)<em> = 0.4.</em>
Answer:
Radiant, chemical
Explanation:
it turns the radiant energy from the sun into chemical sorry if I am wrong but I am vary sure I am right
The empirical formula : Na₂Cr₂O₇
<h3>Further explanation</h3>
Given
170 g sample contains :
29.84 g sodium, 67.49 g chromium, and 72.67 g oxygen
Required
The compound's empirical formula
Solution
mol ratio of elements :
Na : 29.84 : 23 g/mol = 1.297
Cr : 67.49 : 51,9961 g/mol = 1.297
O : 72.67 : 16 g/mol = 4.54
Divide by 1.297
Na : Cr : O = 1 : 1 : 3.5 = 2 : 2 : 7
Since lead time is the time period between <span>the starting and completion of producing a product, lead time is a major process flow structure.</span>
