A block has a density of 1.73 g/mL. What is the block's density in mg/L?
172

Answers

Answer 1

A block has a density of 1.73 g/mL has a density of  1.73 * 10⁶ mg/L.

What is density of a substance?

The density of a substance is the ratio of the mass of a a given volume of a substance and the volume of that substance.

Mathematically, the density of a substance is given by the formula shown below:

Density = mass of substance/volume of substance.

Depending on the units in which the mass and volume of the substance is given, the unit of density can be given as follows:

kilogram per cubic meter; kg/m³

gram per cubic centimeter; g/cm³

gram per liter; g/L

milligram per liter; mg/L

The given block  has a density of 1.73 g/mL.

To convert from gram to mg, we multiply by 1000

1.73 g = 1.73 * 1000 = 1730 mg

to convert from mL to L, we divide by 1000

1 mL = 0.001 L

Density of the block in mg/L = 1730 mg/ 0.001 L

Density of the block in mg/L = 1.73 * 10⁶ mg/L

To make a water-insoluble substance water-soluble, a chemist could add groups with bonds between.

Answers

To make a water insoluble substance water soluble, a chemist can add groups with bonds between atoms with different attraction for electrons.

A water soluble drug or substance is easier to be taken up in your digestive system.

Positive and negative are attracted which makes a cohesive structure. When polar compounds or ions gets added to the water, these compounds breaks down or degrades into smaller components. They also might dissolve to become the part of the solution.

The partial charges of water attracts the various parts of a compound. When attraction occurs, it gets more soluble in the water.

Answers

Water is most  polar solvent that is used for the process of re-crystallization and Ethanol is less polar than water .  Ethanol is miscible with both water and hexane.

Water acts as a polar solvent because it can attracted to either the positive or negative electrical charge on the solute .Hence, water is most polar solvent. Ethanol is less polar to water but  very polar molecule due hydroxy group, which forms hydrogen bond with other molecules.Hexane is a non polar compound.

Yes is my final answer

Explanation:

1. Scrap iron is used to displace copper because it is a more reactive, cheaper metal, making it a cost-effective way to produce copper. Scrap or old iron is also easier to obtain, as it is one of the world’s most recycled scrap metals. During a displacement reaction, iron reacts with a copper sulphate solution. This causes the iron ion to displace the copper to form iron sulphate, with solid copper being produced as a result.

Density of a substance is

Density = Mass / Volume

Electronegativity

The tendency of an atom to pull electrons towards itself is called electronegativity.

It is the tendency of an atom to attract bonding pair of electrons towards itself. These atoms which are more electronegative are able to bear a negative charge and be stable.

Unlike electropositive elements which tend to lose electrons , electronegative elements hold on tightly to the electrons.

The electronegativity is measured using the Pauling Scale where the most electronegative element of the periodic table, Fluorine , is given a value of 4 and the rest of the elements have values lower than 4 according to the trends followed by their groups and periods.

The least electronegative element of the periodic table , Cesium has a value of 0.7 on the Pauling Scale.

Electronegativity increases when we move from left to right in the periodic table and it decreases (in general) when we move down the group.

Answers

Answer:

x = 1/2 y = 1

Step-by-step explanation:

Now form equation for y,

→ 6x - y = 2

→ y = 6x - 2

Then the value of x will be,

→ -4x + 3y = 1

→ -4x + 3(6x - 2) = 1

→ -4x + 18x - 6 = 1

→ 14x = 1 + 6

→ x = 7/14

→ [ x = 1/2 ]

Hence, the value of x is 1/2 (or) 0.5.

Now the value of y will be,

→ y = 6x - 2

→ y = 6(1/2) - 2

→ y = 3 - 2

→ [ y = 1 ]

Hence, the value of y is 1.

Emeralds are composed of 4 different elements in a fixed proportion. they are composed of 5.030% beryllium, 10.040% aluminum, 31.351% silicon and 53.579% oxygen. the empirical and molecular formula are the same

Answers

The empirical formula of emerald is Be3Al2Si6O18.

The empirical formula of a compound tells us about the simplest ratio between the atoms present in the compound.

We are given that emerald consists of 5.030% beryllium, 10.040% aluminum, 31.351% silicon and 53.579% oxygen.

So, we need to first convert the percentages into number of moles of the elements.

Let us assume that there is 100 grams of emerald.

Hence, the mass of each element in it is 5.030 grams beryllium, 10.040 grams aluminum, 31.351 grams silicon and 53.579 grams oxygen.

To calculate the moles, we need to divide their given mass by their molar mass

Moles of beryllium(Be) = 5.030/9 = 0.55

Moles of aluminium(Al) = 10.040/27 = 0.37

Moles of silicon(Si) = 31.351/28 = 1.107

Moles of oxygen(O) = 53.579/16 = 3.34

Now, we need to divide the moles by the lowest common number among them i.e, 0.37.

So, 0.55/0.37 = 1.5

0.37/0.37 = 1

1.107/0.37 = 3

3.34/0.37 = 9

So, the ratio of Be:Al:Si:O comes out to be 1.5:1:3:9.

As the ratio contains 1.5, so we need to multiply it by 2 to get a whole number.

So, (1.5:1:3:9) x 2 = 3:2:6:18

Thus, the empirical formula of emerald is Be3Al2Si6O18.

The Haber process is typically carried out at a temperature of approximately [tex]500^{0}C[/tex]. The rate of the forward reaction would be decreased if the temperature were lowered to [tex]100^{0}C[/tex].

For every [tex]10^{0} C[/tex] increase in temperature, most reactions double in rate. On the other hand, a temperature that is too low cannot be used because the rate of the reaction will be significantly slowed. As a result, a compromise temperature  [tex]450^{0}C[/tex] is used, which is high enough for the rate to be quite fast but low enough to yield a relatively high ammonia yield. This reaction takes place at a pressure of 200 atm. 

Higher temperatures accelerate the rate of reaction. We've seen that when reactions are carried out at a higher temperature, the rate of reaction increases. A higher temperature would allow the Haber process to occur more quickly.

Temperature increases typically increase the rate of reaction. The average kinetic energy of the reactant molecules increases as the temperature rises. As a result, a larger proportion of molecules will have the minimum energy required for an effective collision.

A chemist adds a chemical to pure water and there is a 100-fold increase in the concentration of hydrogen ions. What is the best approximation of the new ph value?.

Answers

If a chemist adds a chemical to pure water and there is a 100-fold increase in the concentration of hydrogen ions then the best approximate value of new pH is 5.

When only pure water is there.

H₂O ⇌ H⁺ + OH⁻

pKw = pH + pOH

14 = pH + pH ( This is because the value of pH and pOH is same in water and we need to consider pH here.)

14 = 2pH

pH= 14/2 = 7

So, pH of pure water is 7.

Concentration of hydrogen ions in pure water can be calculated using the equation

pH = -log[H⁺]

7 = -log[H⁺]

[H+] = 10⁻⁷ M

So, the concentration of hydrogen ions in pure water is 10⁻⁷ M.

Now, the chemist added a chemical to this pure water such that there is   100- fold increase in concentration of hydrogen ions.

So, the new concentration of hydrogen ions is calculated as shown below.

[H⁺] = 100 ×10⁻⁷ M

      = 10⁻⁵ M

The new concentration of hydrogen ions is 10⁻⁵ M.

Now, the new pH can be calculated using the formula

pH  = -log[H⁺]

      = -log[10⁻⁵]

      = -×-5log[10]        

       = 5×1

Since, the concentration of amino acid and NaOH are same, that is 0.1 M.

   Concentration of amino acid = concentration of NaOH

                                          0.1 M = 0.1 M
