Answer:
metano= CH4
C= 12 g/mol
H= 1g/mol x 4 = 4g/mol
CH4= 12g/mol + 4g/mol = 16g/mol
(las masas están aproximadas).
AsH3 has five valence electrons, so the molecule will have 3 bonding domains and one non-bonding domain (lone pair) around the central atom. The geometry is trigonal pyramidal, and the angles are around 107 degrees.
AsH3 and hydrogen are very close in electrongativity, so there really is no partial charges. There may be a slight electron pull towards hydrogen, but it would be nearly insignificant
Answer:
light, heat, and sound. Hope i helped!
Explanation:
EDIT: oh yeah theres also energy lol how did i miss that?
Answer:
The total number of molecules remains the same
The heat lost by the beads is equal to the heat gained by the water. The specific heat capacity of water is 4.18 joules/gram. "w" will denote water's property and "b" will denote the beads' properties.
mw x Cpw x ΔTw = -mb x Cpb x ΔTb
100 x 4.18 x (29.9 - 25) = 34.5 x Cpb x (100 - 29.9)
Cpb = 0.84 joules/gram
