How might sharing data gathered by different regions allow scientists to better predict the weather.

By sharing data from different regions, this allows scientists to better predict the weather. Weather travels in patterns. If it is raining in England there is a chance it will rain in Germany. This all has to do with the wind patterns

How does the structure of amino acids allow them to form a polypeptide

melamori03 [73]

Amino acids which are known to be linked by peptide bonds they form polypeptide chains.

Proteins are linear polymers are formed by way of linking an a-carboxy group of one amino acid to a-amino of different amino acids which have peptide bond. The formation which results from two amino acids which result in a loss of a water molecule. The best process of the reaction is hydrolysis.

An atom that has 13 protons and 15 neutrons is isotope of the element A.) nickel B.) silicon C.) aluminum D.) phosphorus. Why?

joja [24]

An atom that has 13 protons and 15 neutrons is isotope of Aluminium (answer C)

Explanation

Isotope is a form of the same element with the equal number of protons but difference number of neutrons in their nuclei.

In other words isotope has the same atomic number but different mass number.

Atomic number of a element is determined by number of protons of an element.

from the periodic table Aluminum in atomic number 13 therefore it has 13 protons therefore an atom that has 13 protons and 15 neutrons is a isotope of Aluminium.

A rectangular block of solid carbon (graphite) floats at the interface of two immiscible liquids.

Sergio039 [100]

Explanation:

Let us take the volume of block is x.

Since, the block is floating this means that it is in equilibrium. Formula to calculate net force will be as follows.

$F_{net} = Buoyancy force(F_{b}) - weight force(w)$

Also, buoyancy force $(F_{b})$ = (volume submerged in water × density of water) + (volume in oil × density of oil)

$(F_{b})$ = $(0.592 V \times \rho) + (1 - 0.592)V \times 1000 g$

= $(0.592 V \times \rho + 408 V)$ g

As, W = V × density of graphite × g

It is given that density of graphite is $2.16 g/cm^{3}$ or 2160 $kg/m^{3}$ .

So, W = 2160 V g

$F_{net}$ = (0.592 V \rho + 408 V) g - 2160 V g = 0

$0.592 \rho$ = 1752

$\rho$ = 2959.46 $kg/m^{3}$ or 2.959 $g/cm^{3}$ is the density of oil.

It is given that mass of flask is 124.8 g.

Mass of 35.3 $cm^{3}$ oil = $35.3 \times 2.959$ 104.7 g

Hence, in second weighing total mass will be calculated as follows.

(124.8 + 104.7) g

= 229.27 g

Thus, we can conclude that in the second weighing mass is 229.27 g.

Carbon dioxide and water react to form bicarbonate ion and hydronium ion. Hyperventilation (rapid breathing) causes more carbon

Juliette [100K]

Hyperventilation will blow off carbon dioxide which reduces the alkaline component of the blood, resulting in acidosis and a lower blood pH. (See Andromeda Strain). This is why re-breathing into a bag to increase carbon dioxide in your blood will make you feel less faint. Basically It increases the pH ... you can look at CO2 as an acid ... and when reduced ... alkalinization of the pH occurs

Describe in general terms the structure of ionic solids such as nacl

allochka39001 [22]

Ionic compounds are chemical compounds in which ions are held together in a lattice structure by ionic bonds. They have a high melting and boiling point, and they have a high hardness and are very brittle. The cations and anions are stuck together in a sense. So in this case, sodium (Na) is attracted to Chlorine (Cl).
