the protein’s specific sequence is?
Answer:
The linear sequence of amino acids within a protein is considered the primary structure of the protein. Proteins are built from a set of only twenty amino acids, each of which has a unique side chain. The side chains of amino acids have different chemistries.

The density of gold is 19. 3 g/cm3. What is the volume of a 13 g gold nugget? (Density: D = ). 25 cm3. 67 cm3 1. 48 cm3 2. 50 cm3.
Answer:
0.67 cm³Explanation:
The volume of a substance when given the density and mass can be found by using the formula
[tex]volume = \frac{mass}{density} \\[/tex]
From the question
mass = 13 g
density = 19.3 g/cm³
We have
[tex]volume = \frac{13}{19.3} \\ = 0.673575...[/tex]
We have the final answer as
0.67 cm³Hope this helps you

There are no transition elements between the Group 2 element magnesium and the
Group 3 element aluminium.
Give a reason why, in terms of electronic structure.
Answer:
Atomic orbital energy ordering.
Explanation:
The transition metals constitute the d-block. The answer to your question has to do with the energy ordering of atomic orbitals. Specifically, the 3s orbitals are lower in energy than 3p, which are lower in energy than 4s, which are lower in energy than 3d (remember the principal quantum number for d orbitals is one minus the principle quantum number of the shell so n = 4 level's d orbitals are the 3d orbitals). According to the Aufbau principle, atomic orbitals are filled with electrons from the lowest energy up. So the orbitals would have to be filled in the order of 3s, 3p, 4s, and then 3d. Magnesium has its last valence electron residing in the 3s orbital and Aluminum has its last valence electron residing in the first 3p orbital (specifically the 3px orbital, which is aligned horizontally in the 3d plane. The three p orbitals for all principle quantum levels are px, py, pz, with the x, y, z describing the orientation in the 3d plane). The 3d has not yet been reached in terms of energy ordering. This is why there are no transition elements between magnesium and aluminum, in terms of electronic structure.

Answer:
Liquid
Explanation:
Liquid
Answer:
Gas
Explanation:
Gas takes the shape and volume of its container because it doesn't have a definite shape or volume.
Liquid is wrong because it takes the shape of its container, but has a definite volume.
Gas is wrong because it has a definite shape and volume.
Crystal is definitely wrong.

How to add moisture to the air without a humidifier?
There are quite a few ways to add moisture into the air without a humidifier
A few things that can help add moisture are hanging your clothing to dry. hang drying your damp clothes will add moisture to the air over time as it evaporates and it will make your house smell like fresh clothes.
Another thing is a bath, allow the water to cool off and leave the bathroom door open, the steam will add moisture to the air as the water cools.
This might seem silly but putting bowls or vases of water out on the windowsill on a sunny day mill moistens the air as it evaporates.
You can also get houseplants, moisture evaporates from the leaves and stems of plants. transpiration can help increase the humidity in your home.
not sure if this is the answer you were looking for but if so im glad i could help. have a great day!
When the metal was added to the calorimeter, some of the water splashed out. How would the loss of water in the Styrofoam cup affect the final temperature
The final temperature of the cup may be less than accurate thereby affecting the entire results of the experiment carried out using the cup.
A styrofoam cup is an insulated material. A styrofoam cup prevents heat gain or looses from the cup. Heat is gained by the water inside the styrofoam cup. The cup prevents exchange of energy with the environment.
When water is lost from the styrofoam cup, the final temperature of the cup may be less than accurate thereby affecting the entire results of the experiment carried out using the cup.

Pls help me!! Explain how the N:Z ratio can help predict the type of radiation Zr-85 and Zr-95 emit.
No links pls
Based on N:Z ratio, Zr-85 is expected to decay by positron emission. Zr-95 is expected to emit beta particles in a beta decay.
The N:Z ratio determines the stability of a nucleus. If a nucleus has N:Z ratio >1.5 or <1.0, such a nucleus is unstable and will undergo radioactive decay. The aim of such a decay is to attain a favorable N:Z ratio.
For Zr -85, the N:Z ratio is 1.1 while the N:Z ratio of Zr-95 is 1.4. Zr -85 is expected to decay by positron emission which increases the N:Z ratio. For Zr-95, the nucleus tends to undergo processes that decrease the N:Z ratio such as beta emission.

Calculate the normality of a solution made by diluting 12 g of H3PO4 with water to produce 250.0 mL of solution.
The normality of a solution made by diluting 12 g of H3PO4 with water to produce 250.0 mL of solution is 1.47 eq/L.
The normality of a solution is;
N = Mass of solute in grams/volume of solution in litres × Equivalent weight
Mass of solute = 12 g
volume of solution = 250.0 mL or 0.25 L
Equivalent weight = Molar mass of H3PO4/n
n = Number of hydrogen ions in H3PO4
Equivalent weight = 98 g/mol/3 = 32.7
Substituting values;
N = 12/0.25 × 32.7
N = 1.47 eq/L
