Li2O.. Because Li is +1 and O2 is -2
Answer:
66622.653 mi/hr
Explanation:
The average speed at which the Earth rotates around the Sun = 29.783 km/s
Also, The conversion of km to miles is shown below:
1 km = 0.621371 miles
The conversion of s to hr is shown below:
1 s = 1 / 3600 hr
So,

Thus,
<u>The average speed at which the Earth rotates around the Sun in miles per hour = 66622.653 mi/hr</u>
The correct answer for the question that is being presented above is this one: "B) Temperature."
Here are the following choices:
A) all of these measurements are needed
B) Temperature
C) Molar Mass
D) Pressure
E) Mass
Answer:
HBr, CH3C(OH)2 and CH3COOH, Br-
Explanation:
The conjugate acid-base pairs acid reacts with base to form a conjugate acid and conjugate base.
Conjugate acid is formed when a bases receives a proton (H+) and a conjugate base is formed when an acid losses a proton (H+).
From the given equation:
HBr, CH3C(OH)2 and CH3COOH, Br- are conjugate acid-base pair, where HBr is an acid and CH3C(OH)2 is a conjugate acid while CH3COOH and Br- is the conjugate base.
