Explanation:

Because when you move the decimal point once, it it equal to 10 and to convert in the metric system, you must multiply or divide by 10. For example, when converting 4 centimeters to millimeters, you can multiply by 10 to get 40 millimeters or you can move the decimal point to the right and add another 0 to get 40.

Answer:

Q = 126.5 kJ

Explanation:

Given that,

Mass, m = 1210 g

Specific heat of water, c =  4.184 J/g°C

Initial temperature, [tex]T_i=20^{\circ} C[/tex]

Final temperature, [tex]T_f=45^{\circ} C[/tex]

We need to find the heat absorbed by water. The formula that is used to find the heat absorbed is given by :

[tex]Q=mc\Delta T[/tex]

Putting all the values in it we get :

[tex]Q=1210\ g\times 4.184\ J/g^{\circ} C\times (45-20)^{\circ} C\\Q=126566\ J\\\\\text{or}\\\\Q=126.5\ kJ[/tex]

So, the amount of heat absorbed is 126.5 kJ.

Answer:

2.08g

Explanation:

Given parameters:

  Volume of CuSO₄  = 3.29mL

  Molarity  = 4M

Unknown:

Mass of CuSO₄ = ?

Solution:

Let us find the number of moles from the given parameters first;

     Number of moles  = molarity x volume

           1000mL = 1L

Express the volume of the given CuSO₄ in L = 3.29 x 10⁻³L

   Number of moles  = 4 x 3.29 x 10⁻³ = 0.013mol

So;

  Mass of CuSO₄ = number of moles x molar mass

      Molar mass of  CuSO₄  = 63.6 + 32 + 4(16) = 159.6g/mol

 Mass of CuSO₄  = 0.013mol  x 159.6g/mol

 Mass of CuSO₄  = 2.08g

5 electrons Nitrogen (N) have around its Lewis dot model. Therefore, the correct option is option D among all the given options.

Nitrogen (N), a nonmetallic element belonging to Periodic Table Group 15 [Va]. It is a colorless, flavorless, and odorless gas that makes up the majority of the atmosphere on Earth and is a component of all living things.

In terms of cosmic abundance, nitrogen is the sixth most abundant element. The main supply of nitrogen for trade and industry is the atmosphere of Earth, which contains 75.51 percent nitrogen by weight. Aside from nitrogen oxides and nitric acid, the atmosphere also includes variable tiny quantities of ammonia and ammonium salts. 5 electrons Nitrogen (N) have around its Lewis dot model.

Explanation:

The cart has a lot of potential energy, little kinetic energy, and little thermal energy when it is in position A. The kinetic energy and potential energy both rise as the cart moves towards position B, while the thermal energy rises as thermal energy from the track is transmitted to the cart through friction

Kinetic energy, which may be seen in the movement of an object, particle, or group of particles, is the energy of motion.

The cart has a lot of kinetic energy, little potential energy, and little thermal energy after it reaches position C. The cart has some thermal energy and a high potential energy at point D.

It also has a low kinetic energy. Gravity, momentum, and friction are all connected with potential energy, kinetic energy, and thermal energy, respectively.

Position A is when the potential energy is at its highest, and its kinetic energy is at its peak in position C and at its lowest in position A, whereas thermal energy is at its peak in position B and at its lowest in position A.

From the question

mass = 8.11 g

volume = final volume of water - initial volume of water

volume = 44.72 - 25.26 = 19.46 mL

We have

Answer:

1.55×10²² molecules.

Explanation:

We'll begin by calculating the number of mole in 5.32 g of pure lead (Pb). This can be obtained as follow:

Mass of Pb = 5.32 g

Molar mass of Pb = 207 g/mol

Mole of Pb =?

Mole = mass /molar mass

Mole of Pb = 5.32/207

Mole of Pb = 0.0257 mole

Finally, we shall determine the number of molecules in 0.0257 mole of Pb. This can be obtained as follow:

From Avogadro's hypothesis,

I mole of Pb contains 6.02×10²³ molecules.

Therefore, 0.0257 mole will contain = 0.0257 × 6.02×10²³ = 1.55×10²² molecules.

Therefore, 5.32 g of pure lead (Pb) contains 1.55×10²² molecules.

Answer:

A) oxygen moles/sec = 48 * 10 ^-14  mol/sec

B) mass of oxygen = 1536*10^-14 grams

Explanation:

cross sectional area of cylinder = 2cm^2 = 2 * 10^-4 m^2

length of cylinder = 5 cm = 0.05 m

concentration at one end = 0.2 mol m^-3

concentration falls linearly at other end = 0.05 mol m^-3

Diffusion constant of oxygen = 8 * 10^-10  m^2 s^-1

A ) Number of moles of oxygen passing every second

 N = A * D * [tex]\frac{dc}{dt}[/tex]   ------- ( 1 )

A = area , D = diffusion constant,  [tex]\frac{dc}{dt}[/tex] = rate of change of diffusion

dc /dt = ( 0.2 - 0.05 ) / 0.05  = 3 mol m^-4

back to the equation

N = ( 2 * 10^-4 ) * ( 8 * 10^-10 ) * ( 3 ) = 48 * 10 ^-14  mol/sec

B) Mass of oxygen passing down the cylinder each second

This can be obtained by converting : 48 * 10^-14 moles to grams

1 mole of oxygen  =  32 grams of oxygen

therefore : 48 * 10^-14 moles of oxygen = ( 32 * (48*10^-14) = 1536*10^-14 grams

You will need to look up the Standard Heats of Formation* for each substance and apply Hess's Law Equation.

ΔH⁰(rxn) = ∑ΔH⁰(Products) - ∑ΔH⁰(Reactants)

*Std Heats of Formation can be found in the appendix of most college chem texts.

For this problem:

Given               CaCO₃(s)       =>           CaO(s)        +      CO₂(g)

∑ΔH⁰:          -635.1 Kj/mole            -393.5Kj/mole         -1206.9

ΔH⁰(rxn) = [(-393.5 Kj/mole) + (-393.5Kj/mole)] - (-1206.9Kj/mole)

= (-635.1 -393.5 + 1206.9) Kj/mole

= +178.3 Kj/mole

Over 68 per cent of the fresh water on Earth is found in icecaps and glaciers, and just over 30 per cent is found in groundwater. Only about 0.3 per cent of our freshwater is found in the surface water of lakes, and rivers.

The Earth is a watery place. About 71 per cent of the Earth's surface is water-covered, and the oceans hold about 96.5 per cent of all Earth's water.

The majority of Earth’s fresh water is stored in underground aquifers.

Aquifers are layers of sedimentary formations such as sandstone and fractured hard rocks where water after infiltration from soil reaches and fill the interstitial spaces.

Aquifers are huge in size in basins and contain a huge amount of underground water of fresh quality.

So, over 68 per cent of the freshwater is present on Earth.

where

C1 is the concentration of the stock solution

V1 is the volume is the volume of the stock solution

C_2 is the concentration of the diluted solution

V2 is the volume of the diluted solution
