A toy balloon filled with air has an internal pressure of 1.25 atm and avolume of 2.50 L. If I take the balloon to the bottom of the ocean wherethe pressure is 95 atmospheres, what will the new volume of the balloonbe? How many moles of gas does the balloon hold? (Assume T 285 K)

Answers

Ideal Gas Law
Given: P1= 1.25 atm P2= 95 atm
V1= 2.50 L

Unknown: V2=?

Formula: V=nRT/P; n = RT / PV

Solution: n = (0.0821 L x atm / K x mol) (285K) / (1.25 atm) ( 2.50L)

= 23.40 / 3.125

Answer: n = 7.49 moles of gas the balloon holds

Which of the following statements about elements and atoms is true?

Answers

Atoms of different elements are different based on the number of protons they have in their nucleus. This number, known as the atomic number, is unique to each element and defines its identity.

The modern atomic theory states that atoms of one element are the same, while atoms of different elements are different. What makes atoms of different elements different? The fundamental characteristic that all atoms of the same element share is the number of protons.

All atoms of hydrogen have one and only one proton in the nucleus; all atoms of iron have 26 protons in the nucleus. This number of protons is so important to the identity of an atom that it is called the atomic number (Z).

The number of protons in an atom is the atomic number of the element. Thus, hydrogen has an atomic number of 1, while iron has an atomic number of 26. Each element has its own characteristic atomic number.

the first one

Explanation:

An athlete with a high count of red blood cells will perform well in tests of physicalendurance because
(a) waste products will be removed from the body easily.
(b) excess levels of glucose will increase levels of respiration.
(c) the reduced plasma volume will lower carbon dioxide levels.
(d) high levels of oxygen will be available to the muscles.

Answers

Red blood cells are the carriers of oxygen from the lungs to everywhere else
in the body. If there is a high count of red cells in the blood, then high levels
of oxygen will be available to the muscles.
