The metalloids are Boron, Silicon, Geranium, etc and are found to the right of the metals and the left of the nonmetals. Since that is not an option, the best choice would be: The metalloids are located below nonmetals and above metals within a group.
-Are the most used in daily life and basic human needs
(such as oxygen,nitrogen,carbon, etc)
Answer: The reaction of 1 mol of C to form carbon monoxide in the reaction 2 C(s) + O2(g) ( 2 CO(g) releases 113 kJ of heat. How much heat will be released by the combustion of 100 g of C according the the above information? According to the balanced chemical equation;
Explanation:
F = (mass)(acceleration) = ma
m = 55 kg
Vi = 20 m/s
t = 0.5 s
Vf = 0 m/s (since she was put to rest)
a=(Vf-Vi)/t
a=(0-20)/5
a = 40 m/s^2 (decelerating)
F = ma = (55 kg)(40 m/s^2)
F = 2200 N
Answer:
2 CH3COOH + Ba(OH)2 --> Ba(C2H3O2)2 + 2H2O
To make it less clustered, you can use Ac for C2H3O2.
2 HAc + Ba(OH)2 --> Ba(Ac)2 + 2H2O
The acetic acid reacts with the base barium hydroxide to form the salt barium acetate and water.
Explanation:
final answer. C
