Answer:

The production of hydrogen releases CO₂.

Explanation:

Hydrogen is not a primary fuel, it means that it is not available to be used directly, it must be produced. The production generally uses fossil fuels, and in that case, CO₂ is produced, which is a greenhouse gas (GHG).

So, to obtain that fuel, CO₂ is released, which has a negative effect on the environment because it intensifies the greenhouse effect and global warming.

Advocates for the use of hydrogen fuel cells posit that unlike other sources of power, these fuel cells do not emit harmful carbon emissions in the air that cause pollution and affect global warming. Although the chemical process involves burning hydrogen<span>, it emits water, heat and other emissions but not carbon.

I hope my answer has come to your help. God bless and have a nice day ahead!

When the pressure that a gas exerts on a sealed container changes from 22.5 psi to ? psi, the temperature changes from 110 degre
natta225 [31]
Using Gay-Lussac's Law, pressure is proportional to (absolute) temperature in Kelvin. We first convert the temperature values to Kelvin: 110 C = 383.15 K, while 65 C = 338.15 K.
P1/T1 = P2/T2
22.5/383.15 = P2/338.15
P2 = 19.9 psi

1. Calculate the momentum of a 1,500 kg car traveling at 6 m/s.
ziro4ka [17]

Answer:

1.9000kgm/s

2.258,000kgm/s

Explanation:

1.Momentum is given as the product of mass by velocity of an object.

Momentum,p=mv

m=1,500kh, v=6m/s

p=1500*6\\p=9000kgm/s

2.Momentum,p=mv

m=7800kg, v=30m/s

p_1=7800*30\\p_1=234,000kgm/s\\

new mass=7800+800=8600

As mass is increased, so does the resultant velocity as mass is directly proportional to velocity.

p_2=8600*30\\p_2=258,000kgm/s

We could reduce soil erosion and recycle phosphorus from farm and human waste so that we could help make food production sustainable and prevent algae blooms. We can also do land reclamation as well to help solve this problem. With the land, we would have to design a system to where the land could be functional again in order to plant crops, trees, also to help the wildlife that was once a part of the island. Therefore if the design is done before the mining then afterward we can do the reclamation of the land which would help the people to be able to function after the mining. It would also help the future generations that come along after the previous generations. Everyone must work together in the process in order for everyone to survive. If all this is done then the people of the island would not have to import their food. The reclamation process is the most important thing that has to be designed first whether it is land, soil, water, lakes, and clay then after plant trees, vegetation, and other forms of plants to help replenish the land after the mining is done.
