<h3>Further explanation</h3>

Given

Atomic symbol

Required

Atomic composition

Solution

Atomic number = number of protons = number of electrons

Mass Number (A) is the sum of protons and neutrons

Number of protons and Number of Neutrons  in nucleus

Number of electrons in the shell

From the picture:

protons = 3

neutrons = 4

electrons = 3

atomic number = protons = electrons = 3

mass number = protons + neutrons = 3+4 = 7

Near Tatooine's famous Mos Eisley Space port you found a 520.79 mL block of gold. What is the mass in kilograms of this block?
postnew [5]

Answer:

10.051kg of gold is the mass in kilograms

Explanation:

The density of gold is 19.3g/mL. To solve this question we need to convert the volume of the block of gold to grams using its density. Then, we must convert grams to kilograms using the equivalence factor (1000g = 1kg):

<em>Mass in grams:</em>

520.79mL * (19.3g / mL) = 10051g of gold

<em>Mass in kilograms:</em>

10051g of gold * (1kg / 1000g) = 10.051kg of gold

En el laboratorio, un vaso precipitado vacío tiene una masa de 0,50 kg. Este vaso se llena con 300 cm3 de una solución saturada
faust18 [17]

Answer:

Density = 0.0007667 Kg/cm³

Explanation:

Given the following data;

Mass of empty beaker = 0.50 kg

Volume of solution = 300 cm³

Mass of glass+solution = 730 g

To find the density of the solution in the glass;

First of all, we would convert the value in grams to kilograms.

Conversion:

1000 grams = 1 kg

730 = X kg

Cross-multiplying, we have;

X = 730/1000 = 0.73 kg

Next, we would determine the mass of the solution.

Mass of solution = Mass of glass+solution - Mass of empty beaker

Mass of solution = 0.73 - 0.50

Mass of solution = 0.23 kg

Lastly, we would solve for the density of the solution;

Density can be defined as mass all over the volume of an object.

Simply stated, density is mass per unit volume of an object.

Mathematically, density is given by the formula;

Density = \frac {mass}{volume}

Substituting into the formula, we have;

Density = \frac {0.23}{300}

Density = 0.0007667 Kg/cm³

3- Fully folded proteins typically have polar side chains on their surfaces, where electrostatic attractions and hydrogen bonds
Elden [556K]

Answer:

Option C= A hydrogen bond formed between a polar side chain and a hydrophobic side chain.

Explanation:

All three given options a, b and d have common mechanism to accommodate the polar amino acid.

A= A hydrogen bond forms between two polar side chains.

B= A hydrogen bond from between a polar side chain and protein back bone.

D =  hydrogen bond form between polar side chains and a buried water molecules.

All these are use to accommodate the polar amino acid.

While option C is not used. which is:

A hydrogen bond formed between a polar side chain and a hydrophobic side chain.
