atom and what type of ion is it?

Answers

Answer:  the atom is a CATION (ion) of +2 charge.

Explanation:

The charge on an atom = # of protons - # of electrons

                                       = 10 - 8

                                       = +2

When you rub an inflated balloonon your head on a dry day,it can make your hair stand up! what force is that?

Answers

When you rub an inflated balloon on your head and it makes your hair stand up, the force that makes the hair stand up is known as static electricity.

When the balloon is rubbed on the head, electrons from the hair atoms move into the balloon, thus making the balloon to be negatively charged and the hair positively charged due to loss of electrons.

Unlike charges attracts. Thus, when you try to pull the balloon away slowly, the positively charged hair and the negatively charged balloon will attract each other and this is usually what makes the hair stand up.

More on static electricity can be found here: https://brainly.com/question/24160155

Answer:

static electricity

Explanation:

this is because there is an imbalance between negative and positive charges

when you keep on rubbing, a negative charge is created which is carried by electrons.

when you pull the balloon away slowly, the opposite charges attract to each other which makes your hair attract to the balloon

what type of carbohydrates provide the body with a sustained release of energy?

Answers

Answer:

Fiber-rich, complex carbs

Complex carbs with fiber take much longer to digest than simple carbs. This helps to maintain stable blood sugar levels because sugar enters the bloodstream gradually . Complex carbohydrates provide sustained energy and help you feel fuller for longer because they are digested more slowly.

Which form of carbohydrates can your body use for energy?Glucose, also known as blood sugar, is the primary energy source for your body's cells, tissues, and organs. Glucose can be used right away or stored for later use in the liver and muscles.Carbohydrates are the body's preferred fuel source because they can be quickly converted to glucose. A light carbohydrate snack right before exercise is a good idea for quick energy. Eat protein with carbs to slow the rate at which your body absorbs them for longer-lasting energy.Fat is the most concentrated source of energy in the body, providing more than twice the potential energy of carbohydrate or protein (9 calories per gram versus 4 calories each per gram).
