Answer:
C) Q = 14888.5 J
Explanation:
∴ m H2O = 622.7 g
∴ <em>C</em> H2O = 4.18 J/g°C
∴ ΔT= 96.7°C - 90.98°C = 5.72°C
⇒ Q = (622.7 g)(4.18 J/g°C)(5.72°C)
⇒ Q = 14888.508 J
Answer:
Less than 7 ph value are acidic. Greater than 7 ph value are basic.
Answer:
trigonal planar
Explanation:
The molecule SO3 is of the type AX3. The molecule is symmetrical and non polar.
There are three regions of electron density in the molecule. This corresponds to a trigonal planar geometry. This means that the three oxygen atoms are arranged at the corners of a triangle. The bond angle is 120 degrees.
Answer:
A compound is "a substance formed when two or more chemical elements are chemically bonded together." There are two main types of chemical bonds: covalent and ionic.
