Answer:
Nonmetals tend to gain electrons while metals tend to lose electrons.
Explanation:
You would have to use the molarity of calcium hydroxide to find the moles of calcium hydroxide. Once you have moles, just convert using mole:mole ratio and find the grams of sodium hydroxide.
+4 and +6 I think not sure tho
Some measure of examining information
The total heat required to convert the ice to steam is 155,000 J.
The given parameters:
- <em>Mass of the ice, m = 50 g</em>
- <em>Initial temperature of the ice, t = -10 ⁰C</em>
- <em>Final temperature of the ice, T = 0⁰C, 100⁰C and 120⁰C</em>
- <em>Specific heat capacity of water = 4.184 J/g⁰C</em>
- <em>Heat of fusion of ice, = 333.55 J/g</em>
- <em>Heat of vaporization, = 2,230 J/g</em>
