Answer:

29.40182

Explanation:

The pOH of a solution : 13.756

Mass HCl=10.4 g

mol HCl (MW=36.5 g/mol) :

[tex]\tt mol=\dfrac{mass}{MW}=\dfrac{10.4}{36.5}=0.285[/tex]

Volume of HCl = 500 ml = 0.5 L

[tex]\tt M=\dfrac{n}{V}\\\\M=\dfrac{0.285}{0.5}=0.57~M[/tex]

HCl ⇒ H⁺ + Cl⁻

[H⁺]=[HCl]=0.57 M

pH= - log[H⁺]

pH=-log[0.57]=0.244

pH+pOH=14

pOH=14-0.244

pOH=13.756

Answer:

STP conditions imply a temperature of 273.15 K and a pressure of 100 kPa. When tose conditions are met, 1 mole of any ideal gas will have a volume of 22.7 L. So, if 1 mole occupies a volume of 22.7 L, 2 moles will occupy a volume twice as big. Likewise, 0.5 moles will occupy half the volume 1 mole occupies. Assuming that the gas is at standard temperature and pressure (STP), one mole of any gas occupies 22.4 L . This means the number of moles of O2 is 222.4=0.089 mol .

Location: nucleus, contribution to mass: usually about half, charge: positive

Explanation:

Protons are a part of the nuclear particles alongside the neutrons. Protons and neutrons are all together called sub-atomic particles and they share the nucleus at the center of an atom together.

Answer:

inertia

Explanation:

Answer:

Law of inertia, also called Newton's first law, postulate in physics that, if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force.

Answer:

4.5 moles of lithium sulfate are produced.

Explanation:

Given data:

Number of moles of lead sulfate = 2.25 mol

Number of moles of lithium nitrate = 9.62 mol

Number of moles of lithium sulfate = ?

Solution:

Chemical equation:

Pb(SO₄)₂ + 4LiNO₃      →     Pb(NO₃)₄ + 2Li₂SO₄

Now we will compare the moles of lithium sulfate with lead sulfate and lithium nitrate.

                       Pb(SO₄)₂        :         Li₂SO₄

                            1                :             2

                          2.25           :          2/1×2.25 = 4.5 mol

                       LiNO₃            :             Li₂SO₄

                           4                :                2

                           9.62           :             2/4×9.62 = 4.81 mol

Pb(SO₄)₂  produces less number of moles of Li₂SO₄ thus it will act as limiting reactant and limit the yield of  Li₂SO₄.

Explanation:

I majored in Physics

Answer:

A. There will be no change

Explanation:

Velocity is defined as the directional speed of an object in motion. Balanced forces do not result in any change in motion. Thus, there would be no change in velocity.

Answer:

Explanation:

The Kinetic Energy (K.E) of an object can be calculated as:

We are given:

K.E = 480 K

Velocity of the object = v = 8 m/s

Using the values, we get:

Thus, the mass of the object will be 15 kg.

The mass of the object at the given momentum and speed is determined as 5 kg.

The momentum of the object is calculated as follows;

P = mv

where;

m = P/v

m = 40/8

m = 5 kg

Thus, the mass of the object at the given momentum and speed is determined as 5 kg.

Answer:

moles or atoms?

Explanation:

you can't have a molecule of any so there's two different answers that I can give you:

how many moles? 1.5

how many atoms? 9.03x10^23 atoms

At STP 1 mole of an ideal gas occupies 22.4L.

33.6 L x 1 mol/22.4 L = 1.5 moles of Neon

1.5 moles Ne x 6.02x1023 atoms/mole = 9.03x1023 atoms

9.03x10²³ molecules are in 33.6 liters of neon (Ne) gas at STP. At STP 1 mole of an ideal gas occupies 22.4L.

The smallest unit of matter that may be split without producing electrically charged particles is the atom. It is also the smallest piece of substance with chemical element-like characteristics. Electric forces, which link electrons towards the nucleus of atoms, cause them to be drawn to any positive charge.

Space makes up the majority of an atom. The remainder is made up of a cloud of negatively charged electrons around a positively charged nucleus made up of protons and neutrons. Compared to electrons, that are the smallest charged particles in nature, the nucleus is tiny and dense.  

At STP 1 mole of an ideal gas occupies 22.4L.

33.6 L x 1 mol/22.4 L = 1.5 moles of Neon

1.5 moles Ne x 6.02x10²³ atoms/mole = 9.03x10²³ atoms

Therefore, 9.03x10²³ molecules are in 33.6 liters of neon (Ne) gas at STP.

The higher pressure container

Boyle's Law  stated that :

At a constant temperature, the gas volume is inversely proportional to the pressure applied  

[tex]\rm p_1V_1=p_2.V_2\\\\\dfrac{p_1}{p_2}=\dfrac{V_2}{V_1}[/tex]

From the diagram (picture), it shows that the volume of container D is greater than container E, so the pressure applied to container D will be less than the pressure applied to container E

Answer:

H. an exothermic reaction that released thermal energy.

Explanation:

The student will most conclude that this is a chemical reaction in which thermal energy is released to the environment.

Such reactions accompanied by the release of thermal energy are exothermic reactions.

For endothermic reactions, heat is absorbed. At the end of the reaction, the system is cold.
