Answer:
true
covalent bonds are between non metals and nonmetals. and they are sharing electrons.
The molarity and normality of 5.7 g of Ca(OH)2 in 450ml 0f solution is calculated as follows
molarity = moles/volume in liters
moles =mass/molar mass
= 5.7g/74g/mol = 0.077moles
molarity = 0.077/450 x1000= 0.17M
Normality = equivalent point x molarity
equivalent point of Ca(OH)2 is 2 since it has two Hydrogen atom
normality is therefore = 0.17 x2 = 0.34 N
Answer: 208g
Explanation: Since 224 grams produces 96 grams more, then 112 grams will produce 208 grams.
It's melting, so solid to liquid
