I would say A.evaporate because the water is getting absorbed.
Answer:
The correct option is: Br₂--------->2 Br(g)
Explanation:
Bond dissociation is a process in which energy is applied to break a chemical bond between the atoms of a molecule to give free atoms.
In the given reaction: Br₂-------->2 Br(g)
The covalent bond in Br₂ molecule dissociates to give two moles of bromine atoms. Therefore, it is a bond dissociation reaction.
They can try to increase the amount of plants put in the ground because the plants take in the carbon and give us more oxygen to breath healthy.
Answer:
b) 3x10³m³
Explanation:
The volume of each astronaut breathing in m³ is:
500cm³ * (1x10⁻⁶m³ / 1cm³) = 5x10⁻⁴m³
In 1 minute, the volume is:
5x10⁻⁴m³ * 15 = 7.5x10⁻³m³
In 1 hour:
7.5x10⁻³m³ /min * (60min / 1 hour) = 0.45m³/h
In 1 day:
0.45m³/h * (24h / 1 day) = 10.8m³/day
In 1 year:
10.8m³/day * (365 days / 1 year) = 3942m³ = 3.9x10³m³
That is approximately:
<h3>b) 3x10³m³</h3>
