Answer:
combination reaction
Explanation:
i'm not sure i just searched it on the internet
Answer:
This can be solved using Dalton's Law of Partial pressures. This law states that the total pressure exerted by a gas mixture is equal to the sum of the partial pressure of each gas in the mixture as if it exist alone in a container. In order to solve, we need the partial pressures of the gases given. Calculations are as follows:
Explanation:
P = 3.00 atm + 2.80 atm + 0.25 atm + 0.15 atm
P = 6.8 atm
3.5 atm = x (6.8 atm)
x = 0.51
Answer:
The law of constant composition says that the composition of a homogeneous mixture is always the same
Explanation:
The law of constant composition that is also known as Proust's Law says that when two substances react with each other, to form a compound they will always do in a constant weight ratio, that is, the ratio of the masses between two substances that form a compound, must be proportional.
Climax Community
A climax community is the end result of ecological succession. The climax community is a stable balance of all organisms in an ecosystem, and will remain stable unless a disaster strikes.
Human Activity
It's important to note that human activity has the greatest impact on the amount and quality of wildlife habitat in many areas of the world. Wildlife habitat can be destroyed or its quality diminished as a result of urban growth, agricultural practices, pollution, or habitat destruction.
People can also have a positive impact on wildlife populations through improvement and protection of habitat or ecosystems. Planting trees and shrubs and providing sources of food and water in individual yards is one way people can help wildlife.
A chemical substance that gains or accepts electrons from others is called lewis acids. The Lewis acid in the reaction is Trihydridoboron 
<h3>What are lewis acids and bases?</h3>
For the formation of the covalent bonds the molecule or the atoms that accept or gain an electron from the other species present in the reaction are called lewis acids. The species formed after accepting electrons are called a conjugate base.
The species that donates electrons to the other species are called lewis base and the species formed after the electron donation is called a conjugate acid.
Therefore, option B. 
is the lewis acid as it gains an electron.
