Hello there!
The correct answer is B
Remember that acceleration is the change in velocity divided by the change in time.
So, what we need to do here is take +25 divide it by 5.0, which equals to 5
So yeah, that's how we got the acceleration :)
I hope this helps!
Good luck with your Science studies!
Answer:
0.0165 (L) * 0.750 (mol/L) = 0.0124 mol NaOH in 16.5 mL
Explanation:
Answer:
Cl2 at 250 K < Cl2 at 300 K < H2S at 250 K < H2S at 300 K.
Explanation:
Answer:
The answer to your question is: Oxygen (O) and Selenium (Se)
Explanation:
Elements located in group VIA needs to gain 2 electrons to achieve noble gas electron configuration.
Oxygen (O) is located in group VIA so it needs to gain two electrons to become stable.
Strontium (Sr) is located in group IIA so it needs to lose 2 electrons to become stable.
Sodium (Na) is located in group IA so it needs to lose one electron to become stable.
Selenium (Se) is located in group VIA so it needs to gain 2 electrons to become stable.
Bromine (Br) is located in group VIIA so it needs to gain one electron to become stable.
