Answer:
alcohol thermometers are used rather than Mercury thermometers in very cold regions because alcohol has a lower freezing point than Mercury.
Explanation:
Answer:
Dryer sheets stop static cling by absorbing static electricity formed by different fabrics during your dryer cycle. The fabric softeners that coat dryer sheets are positively charged ions to balance the electrons and ions that cause static cling, leaving you with soft clothes without the static.
Explanation:
The acceleration of a car that starts at 12.5 m/s and reaches 25.5 m/s in 5.00 seconds is 2.6m/s².
<h3>How to calculate acceleration?</h3>
The acceleration of a moving object can be calculated using the following formula:
a = (v - u)/t
Where;
- a = acceleration (m/s²)
- v = final velocity (m/s)
- u = initial velocity (m/s)
- t = time (s)
According to this question, a car starts at 12.5 m/s and reaches 25.5 m/s in 5.00 seconds.
a = (25.5 - 12.5)/5
a = 13.0/5
a = 2.6m/s²
Therefore, the acceleration of a car that starts at 12.5 m/s and reaches 25.5 m/s in 5.00 seconds is 2.6m/s².

Moles Pbl2 = 0.8628 g : 461.01 g/mol = 0.001871
moles I = 2 x 0.001871 = 0.003742
[I-] = 0.003742/ 0.0429
= 0.0872 M
