The most abundant alkali metal is *Sodium*
Answer:
Option (3) 334J.
Explanation:
The following data were obtained from the question:
Mass (m) = 1g
Heat of fusion (ΔHf) = 334J/g
Heat (Q) =?
The heat released can be obtained as follow:
Q = m·ΔHf
Q = 1 x 334
Q = 334J.
Therefore, the heat released when 1g is converted to ice is 334J.
Answer:
Lithium Chloride would be the best one
Sodium Hydroxide would be the second best
Explanation:
Answer: The mass is 1030.692 grams (1.03 x 10^3 grams if you apply sig figs)
This is a units conversion problem, we'll first need the molar mass of ammonium sulfate: 132.14 g/mol
Then we can solve so that:
7.80 moles (132.14 g/moles) = 1030.692 grams
Answer:
took the test but the answer is CAT-CGA-TCC mutates to CAT-TCC or in another way its last one d hope this helps
