how many miles of Fe are in 11.8 g of Fe

Answer:

477 ºC

Explanation:

on an isobaric process, an increase on the volume implies an increase on the temperature:

V1/T1 = V2/T2

T2 = V2T1/V1 = 15.0 L×150 K/3.00 L = 750 K

t/ºC = T/K - 273 = 750 K/K - 273

t = 477 ºC

V1: initial volume

T1: initial temperature

V2: final volume

T2: final temperature

Answer:  If a reaction produces a gas such as oxygen or carbon dioxide, there are two ways to measure the reaction rate: using a gas syringe to measure the gas produced, or calculating the reduction in the mass of the reaction solution.

Answer:

When a saturated solution at a high temperature is cooled, why is the solution separated as a solid? When a saturated solution at a high temperature is cooled, inter molecular space between the molecules of the solution decreases. As a result, no more solute can remain in a solution separating out as a solid crystal.

Water forms the basis of almost every type of cosmetic product, including creams, lotions, makeup, deodorants, shampoos and conditioners. Water plays an important part in the process, often acting as a solvent to dissolve other ingredients and forming emulsions for consistency.

Answer:

1. m(NH₄)₂HPO₄ = 1.62 g

2. molesC₃H₇NO₂ = 1.79 moles

3. V = 4.87x10⁹ L

Explanation:

These questions are pretty easy to solve, using the correct expressions and formula.

1. To do this, we just need the density of the (NH₄)₂HPO₄. In this case, the reported density is 1.62 g/mL, therefore:

d = m/V  (1)

Where:

d: density (g(mL)

m: mass of the compound (g)

V: volume of the compound (mL)

As we already have the volume, we can solve for m:

m = d * V  (2)

m = 1.62 * 1

2. To do this, we need the atomic weights of each element that composes the alanine.

C: 12 g/mol;  H: 1 g/mol;   N: 14 g/mol;     O: 16 g/mol

With these atomic weight, let's determine the molar mass of alanine:

MM C₃H₇NO₂ = 3(12) + 7(1) + 14 + 2(16) = 89 g/mol

Now to get the moles, we use the following expression:

moles = m/MM (3)

moles = 159 / 89

3. We have the mass and density of the nitric acid, we just solve for Volume from expression (1) of part 1:

V = m/d  (3)

V = 1.612x10¹⁰ pounds / 12.53 pounds/gallons

V = 1.287x10⁹ gallons

Converting this to liters:

V = 1.287x10⁹ * 3.7854

Answer:

[tex]\boxed {\boxed {\sf 421,786.7818 \ mol \ H_2O}}[/tex]

Explanation:

We are asked to convert from molecules of water to moles.

1 mole of any substance contains the same number of particles (atoms, molecules, formula units, etc). This is Avogadro's Number: 6.022*10²³. In this problem, the particles are molecules of water.

Use Avogadro's Number to make a ratio.

[tex]\frac {6.022 *10^{23} \ molecules \ H_2O}{1 \ mol \ H_2O}[/tex]

Multiply by the number of molecules given: 2.54 *10²⁹

[tex]2.54 *10^{29} \ molecules \ H_2O \times \frac {6.022 *10^{23} \ molecules \ H_2O}{1 \ mol \ H_2O}[/tex]

Flip the ratio so the units of molecules of water cancel.

[tex]2.54 *10^{29} \ molecules \ H_2O \times \frac {1 \ mol \ H_2O}{6.022 *10^{23} \ molecules \ H_2O}[/tex]

[tex]2.54 *10^{29} \times \frac {1 \ mol \ H_2O}{6.022 *10^{23} }[/tex]

Condense the problem into 1 fraction.

[tex]\frac {2.54 *10^{29} }{6.022 *10^{23} }\ mol \ H_2O[/tex]

[tex]421786.7818 \ mol \ H_2O[/tex]

2.54 *10²⁹ molecules of water are 421, 786.7818 moles of water.

Answer:

H2O

=(1×2)+(8)

=20

Explanation:

We have 1 Hydrogen(H) and 8 Oxygen(O)neutrons . Following the molecule formula, H2O, which means we have 2 Hydrogen that needs to times with 1 neutron;and we have only 1 Oxygen which has 8 neutrons. So 2 (H) have to times 1 and 1(O) have to times 8.

Answer:

t = 50 s

Explanation:

P = W/t

Solving for t,

t = W/P = (3430000 J)/(68600 Watts)

= 50 s

Note: 1 Watt = 1 J/s

According to the question, the time that is taken by the crane which has the power of 68600 W to 3430000 J of work is 50 seconds.

Power may be defined as the amount of energy that is significantly transmitted or converted per unit of time. In a more simple sense, it is also characterized as the measure of the rate of doing work.

According to the question,

The power of the crane = 68600 W.

The amount of work that the crane has to do = 3430000 J.

Time may be calculated with the help of the following formula:

Therefore, according to the question, the time that is taken by the crane which has the power of 68600 W to 3430000 J of work is 50 seconds.
