Answer:
hydrogen is a colorless, odorless, nonmetallic, tasteless, highly flammable diatomic gas
Explanation:
Hydrogen is part of the Noble gas family
1. molarity = (moles)/vol in litres
0.5=[(weight/40)*1000]/4
0.5 = weight/16
weight of NaOH = 8 grams
2. weight = 0.45*850*84/100 gms
molecular weight = 85m (not sure abt this)
Answer:
The rows on the periodic table are called periods. All the elements in a period have valence electrons in the same shell. The number of valence electrons increases from left to right in the period. When the shell is full, a new row is started and the process repeats.

Answer:
The pressure of the gas is 0.278 atm
Explanation:
Step 1: Data given
Number of moles of the ideal gas = 0.540 moles
Volume = 35.5 L
Temperature = 223 K
Step 2: Calculate the pressure of the gas
p*V = n*R*T
⇒with p = the pressure of the gas = TO BE DETERMINED
⇒with V= the volume of the gas = 35.5 L
⇒with n = the moles of the gas = 0.540 moles
⇒with R = the gas constant = 0.08206 L*atm/mol*K
⇒with T = the temperature of the gas = 223 K
p = n*R*T / V
p = 0.540 * 0.08206 * 223 / 35.5
p = 0.278 atm
The pressure of the gas is 0.278 atm
Nuclear fusion
Explanation:
For a given mass, the energy released is greatest for a reaction involving nuclear fusion.
Nuclear reactions generally release far much more energy compared to chemical energy because they involve the interaction between strong nuclear forces. There are two main types of nuclear reactions which are fusion and fission.
Nuclear fusion powers the sun and releases the greatest amount of energy.
- In nuclear fusion, light atoms combines to form heavier ones.
- The reaction degenerates into chain reaction in which huge amount of energy is released.
- This reaction occurs in the core of sun and furnishes the solar system with radiant energy.
