Answer:
CER all starts with a question asked by the teacher. This question is based on a phenomena or lab experience. The student's explanation or answer, as you may have guessed, will consist of three parts: a claim, the evidence, and the student's reasoning. A claim is a statement that answers the question. Start with a hook or attention getting sentence. Briefly summarize the texts • State your claim. Make sure you are restating the prompt. Include a topic sentence that restates your claim and your reason.
Answer:
The melting and boiling points of molecular compounds are generally quite low compared to those of ionic compounds. This is because the energy required to disrupt the intermolecular forces between molecules is far less than the energy required to break the ionic bonds in a crystalline ionic compound (Figure 6.2. 1) .
Explanation:
hopefully this helps :)
if not then here. (Most of the time, the melting points of ionic compounds are very high compared to the melting points of molecular compounds.)
Answer:
the answer is D =decreasing the temperature ️️️
Answer:
480.40 g.
Explanation:
- According to the balanced equation:
<em>2 SO₂(g) + O₂(g) → 2 SO₃(g),</em>
it is clear that 2.0 moles of SO₂ react with 1.0 mole of oxygen to produce 2.0 moles of SO₃.
- We can get the no. of moles of SO₃ produced:
∵ 2.0 moles of SO₂ produce → 2.0 moles of SO₃, from the stichiometry.
∴ 6.0 moles of SO₂ produce → 6.0 moles of SO₃.
- Then, we can get the mass of the produced 6.0 moles of SO₃ using the relation:
<em>mass = no. of moles x molar mass of SO₃</em> = (6.0 moles)(80.066 g/mol) = <em>480.396 g ≅ 480.40 g.</em>
The given question is incomplete. The complete question is :
Which anion would bond with K+ in a 1: 1 ratio to form a neutral ionic compound?
a) 
b) 
c) 
d) 
Answer: b)
Explanation:
For formation of a neutral ionic compound, the charges on cation and anion must be balanced. The cation is formed by loss of electrons by metals and anions are formed by gain of electrons by non metals.
Here potassium is having an oxidation state of +1 called as cation and thus is an anion must have an oxidation state of -1 if they have to combine in 1: 1 ratio to give neutral ionic compound.
Thus the anion has to be 
which combines with 
in 1: 1 ratio to give
