Answer:
FBr is a chemical formula representing "flourine monobromide."
Explanation:
Of course, FBR could represent a number of things, from the Federal Board of Revenue to a fluidized bed reactor. I gave the answer I did because you listed this question as Chemisty.
Answer:
Increasing precision with multiple measurements
Explanation:
The more measurements you take (provided there is no problem with the clock!), the better your estimate will be. Taking multiple measurements also allows you to better estimate the uncertainty in your measurements by checking how reproducible the measurements are.
In ionic bonding, atoms SHARE ELECTRONS
Answer:
Change in temperature = ΔT = 26.8°C
Explanation:
Given data:
Heat absorbed = 600 j
Mass = 25.0 g
Specific heat capacity = 0.897j /g°C
Change in temperature = ΔT= ?
Solution:
Formula:
q = mcΔT
600 j = 25.0 g ×0.897 j/g°C×ΔT
600 j = 22.425 j/°C×ΔT
ΔT = 600 j /22.425 j/°C
ΔT = 26.8°C
