The chemical formula for steam is H2O(g)
mass of steam = mole of steam * molar mass of H2O
= 1 * (1*2+16) = 18 g
by E = m * c * change in temperature,
From 140C steam to 100C steam
18 * 2.01 * (140-100) = 1447.2J
latent heat of vaporization of water = 2.26x10^6 J/kg* 0.018 = 40680 J
From 100C water to 0C water
18 * 4.2 * (100-0) = 7560 J
latent heat of fusion of ice = 334 J/g * 18 g = 6012 J
From 0C ice to -45C ice
18 * 2.09 * (45-0)
= 1692.9 J
1447.2 + 40680 + 7560 + 6012 + 1692.9 = 57392.1 J
Answer: 7.71 + 4.31 + 1.7 + 4.00141=
17.72141
7.71 x 4.31 x 1.7 x 4.00141= 226.04433255
Explanation:
(i) 7.71 + 4.31 + 1.7 + 4.00141
= 7.71000+4.31000+1.70000+ 4.00141 [make like decimals]
= 17.72141 [By adding the corresponding places ]
(ii) 7.71 x 4.31 x 1.7 x 4.00141 =( 7.71 x 4.31) x 1.7 x 4.00141
= 33.2301 x 1.7 x 4.00141
= (33.2301 x 1.7) x 4.00141
= 56.49117 x 4.00141
= ( 56.49117 x 4.00141 )
= 226.04433255
Hence, 7.71 + 4.31 + 1.7 + 4.00141=
17.72141
7.71 x 4.31 x 1.7 x 4.00141= 226.04433255
A sodium chloride is like most of the ionic compounds
existing here on earth in which they are composed of having a high melting
point and by this, if found in underground rock deposits, they are usually in a
form of solid.
Answer:
Anabolic Reaction : Photosynthesis
Occurs in plant life : Both
a way to store energy : Both
Catabolic Reaction : Cellular Respiration
a way to release energy : Both
involves oxygen and carbon dioxide : oxygen releases by the process of photosynthesis. Oxygen is involved in areobic respiration and not in anarobic respiration.
