Answer:
24 moles
Explanation:
given data
= 48 grams
to find out
how many moles of 
will be produced
solution
we know that Stoichiometry is here as
......................1
so we get here mole of solute that is express as
mole = 
..........................2
put here value for
mole = 
mole of = 24 mole
and
we can say that here as per equation 1 that one mole of is go with one mole of
so here 24 mole is go with 24 moles mole of
so we can say will be produced 24 moles
Answer:
The electron dot diagram shows the arrangement of dots without identifying the element.
? with 2 dots each above and right and 1 dot each below and left.
Which element’s symbol could replace the question mark in the diagram?
carbon (C)
tellurium (Te)
beryllium (Be)
cesium (Cs)
Explanation:
Answer: letter b.
Why?
Because Entropy(ΔS) INCREASES when INCREASING disorder in a reaction.
A. INCORRECT. Negative ΔS. This is because there are less molecules of gas in the products compared to the reactants.
B. CORRECT. Positive ΔS. This is because you are increasing disorder by breaking down a solid(highly ordered) molecule into two ions in solution(in solution they are less ordered).
C. INCORRECT. Negative ΔS. This is because you are going from a (g)gas which has more disorder to a (s)solid which has much less disorder than a gas.
D. INCORRECT. Negative ΔS. This is because you are decreasing disorder by building a single molecule. There are also more moles of gas on the reactants side indicating a negative ΔS.

Answer:
25°C
Explanation:
To convert from Kelvin to Celcius we can use this equation:
Temperature in Kelvin - 273 = Temperature in Celcius
298K - 273 = 25°C
