Methane CH4 1 carbon atom : 4 hydrogen atoms
Sulfuric acid H2SO4 2 hydrogen atoms : 1 sulfur atom: 4 oxygen atoms
A triple covalent bond can be formed between d) C & O
The final temperature of the water after dropping the iron ball has been 60.
The heat transferred by the iron ball can be given by:
Heat (Q) = mcT
Q = heat transferred = 8.4 kJ
Q = 8400 J
m = mass = 200 g
c = specific heat = 4.2 J/g.
T = change in tempertaure = Initial temperature - final temperature
T = Final temperature - 50
8400 J = 200 g 4.2 J/g. (Final temperature - 50 )
Final temperature = 60.
The final temperature of the water after dropping the iron ball has been 60.
Transparent is completely clear, like a clean window.
Translucent is like a really dirty window, because it still allows light in, but you cant really see through it.
I hope this helps! :)
Answer:
f(x) = 6x²-3
f(x) = 0
6x²-3 = 0
6x² = 3
x² = 3/6
x² = 1/2
x = 1/√2 , -1/√2
Roots of f(x) = 1/√2 , -1/√2
Verification = (i) 6(1/√2)² - 3
= 6(1/2) - 3
= 3-3
= 0
(ii) 6(-1/√2)² - 3
= 6(1/2) - 3
= 3-3
= 0
