Answer: 274.75 mL
Explanation:
Initial volume of gas V1 = 250.0 mL
Initial temperature of gas T1 = 30.0 C
Convert temperature in Celsius to Kelvin
(30.0°C + 273 = 303K)
New volume V2 = ?
New temperature T2 = 60.0 C
(60.0°C + 273 = 333K)
Since, volume and temperature are involved while pressure is constant, apply the formula for Charles law
V1/T1 = V2/T2
250.0 mL/303K = V2/333K
Cross multiply
250.0 mL x 333K = 303K x V2
83250 = 303V2
V2 = 83250/303
V2 = 274.75 mL
Thus, the volume will be 274.75 mL
Answer: Blue liquid density = 45 grams/70 mL Density = .64 g/mL Yellow liquid density = 80 grams/ 65mL Density = 1.23 g/mL After the liquids are combined the blue less dense liquid will rise to the top, while the yellow more dense liquid will sinks to the bottom.
Sodium has 11 protons, therefore number of neutrons must be 23 – 11 = 12 neutrons.
Sodium has 12 neutrons.
<h3>What are neutrons?</h3>
The neutron is a subatomic particle with the symbol n that is slightly heavier than a proton and has a neutral charge (i.e., neither a positive nor a negative charge). Atoms' nuclei are made up of protons and neutrons. Protons and neutrons are both referred to as nucleons because of how similarly they function inside the nucleus and because they both have masses that are about equal to one atomic mass unit. Nuclear physics describes their characteristics and interactions.
The arrangement of electrons around an atom's hefty nucleus largely determines its chemical characteristics. The amount of protons, or atomic number, determines the charge of the nucleus, which determines the electron configuration.
