kondor19780726 [428]
Self-awareness is the ability to focus on yourself and how your actions, thoughts, or emotions do or don't align with your internal standards. If you're highly self-aware, you can objectively evaluate yourself, manage your emotions, align your behavior with your values, and understand correctly how others perceive you.

A chemist has a 3.25-mole sample of potassium (K) to use in an experiment. What is the mass of this sample?
s344n2d4d5 [400]
Hi!
• For this you want to convert moles to grams
• To do this you would simply multiple your moles times the atomic mass of potassium
3.25 x 39.098= 127.0685
• So your answer for this should be about 127.07 depending on how you need to round!

If you ate a bite of Whataburger, how would it travel through your digestive system?
solmaris [256]

Answer:

After you eat, it takes about six to eight hours for food to pass through your stomach and small intestine. Food then enters your large intestine (colon) for further digestion, absorption of water and, finally, elimination of undigested food. It takes about 36 hours for food to move through the entire colon.
