B.. it is a combination reaction... A + B--> AB
Outcome (dependent) variable-drinking energy drinks
Test (independent) variable- more aggressive
Answer:
Electrons are found in shells or orbitals that surround the nucleus of an atom. Protons and neutrons are found in the nucleus. They group together in the center of the atom.
Explanation:
-----
Energy lost to condense = 803.4 kJ
<h3>Further explanation</h3>
Condensation of steam through 2 stages:
1. phase change(steam to water)
2. cool down(100 to 0 C)
1. phase change(condensation)
Lv==latent heat of vaporization for water=2260 J/g
![\tt Q=300\times 2260=678000~J](https://tex.z-dn.net/?f=%5Ctt%20Q%3D300%5Ctimes%202260%3D678000~J)
2. cool down
c=specific heat for water=4.18 J/g C
![\tt Q=300\times 4.18\times (100-0)=125400](https://tex.z-dn.net/?f=%5Ctt%20Q%3D300%5Ctimes%204.18%5Ctimes%20%28100-0%29%3D125400)
Total heat =
![\tt 678000+125400=803400~J](https://tex.z-dn.net/?f=%5Ctt%20678000%2B125400%3D803400~J)
Answer: Mass of gas is 0.001 pounds.
Explanation:
Density is defined as the mass contained per unit volume.
Given : Mass of gas = ?
Density of gas =
Volume of gas = 389 ml = 0.389 L (1L=1000ml)
Putting in the values we get:
(1g =0.002 lb)
Thus the mass of gas is 0.001 pounds.
