Answer:
Conservation of Energy and Mass The law of conservation of mass states that in a chemical reaction mass is neither created nor destroyed. For example, the carbon atom in coal becomes carbon dioxide when it is burned. The carbon atom changes from a solid structure to a gas but its mass does not change.
Explanation:
Hope it helps :)
pls mark brainliest :P
Answer:
The four are Ll
The four will have long feathers
Explanation:
A Punnett square is a graphical representation of all possible genotypes of an offspring that is likely to arise from a particular cross or breeding event. To create a Punnett square, knowledge of the genetic composition of the parents is highly required. The two things a Punnett square can tell you are the genotypes and phenotypes of the offspring. In its simplest form, the Punnett square consists of a square divided into four quadrants. A Punnett square allows the prediction of the percentages of phenotypes in the offspring of a cross from known genotypes.
The genotypes of the four offsprings are Ll, Ll, Ll and Ll. This implies that they are all heterozygous. They will all have long feathers since the long feather (L) is dominant in all the species. In terms of phenotype, they will all have long feathers.
Answer:
All secondary consumers will die because they will lose their food source
Answer:
34.2 g
Explanation:
In the Hall-Heroult process, Al³⁺ (from Al₂O₃) is reduced to Al. The reduction half-reaction is:
Al³⁺ + 3 e⁻ ⇒ Al
We can establish the following relations:
- 1 A = 1 c/s
- 1 mole of e⁻ has a charge of 96468 c (Faraday's constant)
- 1 mol of Al is produced when 3 moles of e⁻ circulate
- The molar mass of Al is 26.98 g/mol.
Suppose a current of 6800 A is passed through a Hall-Heroult cell for 54.0 seconds. The mass of Al produced is:

Lithium Fluoride.
