Answer:

23 protons, 23 electrons, 33 neutrons

Explanation:

I don't know why my answer got deleted but no worries, I can answer again. The number of protons and electrons is equal to the atomic number which is 23 and the number of neutrons is 56 - 23 = 33 because atomic mass denotes the number of protons and neutrons.

Answer:

The noble gases are the chemical elements in group 18 of the periodic table. They are the most stable due to having the maximum number of valence electrons their outer shell can hold. Therefore they rarely react with other elements since they are already stable

Answer:

idk but i tryed

Explanation:

The simplest way to use the periodic table to identify an element is by looking for the element’s name or elemental symbol. The periodic table can be used to identify an element by looking for the element’s atomic number. The atomic number of an element is the number of protons found within the atoms of that element.

Answer:

64g of O2.

Explanation:

We'll begin by calculating the number of molecules in 73g if HCl.

This is illustrated below:

From Avogadro's hypothesis, we understood that 1 mole of any substance contains 6.02×10²³ molecules. This implies that 1 mole of HCl also contains 6.02×10²³ molecules

1 mole of HCl = 1 + 35.5 = 36.5g

Thus, if 36.5g of HCl contains 6.02×10²³ molecules, then 73g of HCl will contain = (73 x 6.02×10²³)/36.5 = 1.204×10²⁴ molecules.

Therefore, 73g of HCl will contains 1.204×10²⁴ molecules.

Now, we shall determine the mass of oxygen that will contain 1.204×10²⁴ molecules.

This can be obtained as follow:

1 mole of O2 = 16x2 = 32g

32g of O2 contains 6.02×10²³ molecules.

Therefore, Xg of O2 will contain 1.204×10²⁴ molecules i.e

Xg of O2 = (32 x 1.204×10²⁴)/6.02×10²³

Xg of O2 = 64g

Therefore, 64g of O2 will contain the same number of molecules (i.e 1.204×10²⁴ molecules) in 73g of HCl.

Answer:Carbon containg molecules

Explanation:

Protoplasm is made up of necleus and carbon containing molecules

Answer:

Protoplasm is composed of a mixture of small molecules such as ions, amino acids, monosaccharides and water, and macromolecules such as nucleic acids, proteins, lipids and polysaccharides. In eukaryotes the protoplasm surrounding the cell nucleus is known as the cytoplasm and that inside the nucleus as the neoplasm.

Explanation:

Answer:

-1,300 kJ

Explanation:

P₄  +  3 O₂  ⇒  P₄O₆     ΔH = -1,640.1 kJ    (EQ 1)

P₄O₁₀  ⇒  P₄  +  5 O₂    ΔH = 2,940.1 kJ    (EQ 2)

These are the equations you are given.  You need to make these equations into the equation below.

P₄O₆  +  2 O₂  ⇒  P₄O₁₀  (end equation)

Look at the product side of the end equation.  You need to produce P₄O₁₀.  In the EQ 2, P₄O₁₀ is on the reactant side.  Flip the equation.  Since you flipped the equation, the enthalpy will have the opposite sign.

P₄  +  5 O₂  ⇒  P₄O₁₀    ΔH = -2,940.1 kJ

On the reactant side of the end equation, you need P₄O₆ and 2 O₂.  First, rearrange the equation so that P₄O₆ is on the right side.  In EQ 1, P₄O₆ is on the product side.  Flip the equation.  Like the last one, the sign will change.

Now, cancel out all possible values.  P₄ will cancel out since there is one on each side of the equation.  Since there is 5 O₂ on one side and 3 O₂ on the other, subtract the two and put the remainder on the side of the larger value.

P₄  +  5 O₂  ⇒  P₄O₁₀    ΔH = -2,940.1 kJ

P₄O₆  ⇒  P₄  +  3 O₂     ΔH = 1,640.1 kJ    

P₄O₆  +  2 O₂  ⇒  P₄O₁₀

This should be the resulting equation.  Now, add the two enthalpies together to find the overall enthalpy.

-2,940.1 kJ  +  1,640.1 kJ  = -1,300 kJ

The overall enthalpy is -1,300 kJ.

Answer:

when high-energy particles from the sun are trapped by earth's magnetic field

Explanation:

it is produced by a "depression" in the Earth's magnetic field in that area, caused by the fact that the center of the Earth's magnetic field is deviated from its geographic center by 450 km. Such an anomaly is thought by some to be a side effect of a Geomagnetic Reversal. These radiation belts originate from the Earth's intense magnetic field that is the product of their rotation. That field traps charged particles (plasma) from the Sun (solar wind), as well as charged particles that are generated by interaction of the Earth's atmosphere with cosmic radiation and high-energy solar radiation.

amount of time the two substances are in contact. area in contact between the two substances. specific heat of the material that makes up the substances. the density of the two substances in contact.

The characteristics determine how easily two substances change temperature is amount of time the two substances are in contact, area of contact between the two substances, specific heat of the material that makes up the substances and the density of the two substances in contact. Therefore, option B, C, D and E are correct.

When two substances that have different surface temperatures come in contact, conduction happens. The substance with the higher temperature always transfers energy to the one with the lower temperature.

When two objects with different temperatures come in contact with one another, energy moves from the hotter (higher temperature) object to the cooler (lower temperature) object until both objects reach the same temperature.

The latitude of the location has an impact on the air temperature there. The location's elevation. separation from the ocean.

Thus, option B, C, D and E are correct.

Calcium reacts with water to give calcium hydroxide Ca(OH)2. this product is slightly soluble in water.

Aluminium  is less reactive than Ca, so it reacts with only steam, to give aluminium hydroxide Al(OH)3. This product is insoluble in water.

Answer : The initial concentration of HI and concentration of HI at equilibrium is, 0.27 M and 0.386 M  respectively.

Solution :  Given,

Initial concentration of H_2 and I_2 = 0.11 M

Concentration of H_2 and I_2 at equilibrium = 0.052 M

Let the initial concentration of HI be, C

The given equilibrium reaction is,

    H_2(g)+I_2(g)\rightleftharpoons 2HI(g)

Initially               0.11   0.11            C

At equilibrium  (0.11-x) (0.11-x)   (C+2x)

As we are given that:

Concentration of H_2 and I_2 at equilibrium = 0.052 M  = (0.11-x)

The expression of K_c will be,

K_c=\frac{[HI]^2}{[H_2][I_2]}

54.3=\frac{(C+2(0.058))^2}{(0.052)\times (0.052)}

By solving the terms, we get:

C = 0.27 M

Thus, initial concentration of HI = C = 0.27 M

Thus, the concentration of HI at equilibrium = (C+2x) = 0.27 + 2(0.058) = 0.386 M

Answer:

transferred.

Explanation:

hehe

Answer:

Your answer would be destroyed and Transferred.

Explanation:

The reason why is because energy is never created or destroyed because it is just transferred to different forms of energy. Suich as a ball at the top of a hill. It's not moving, so it has potential energy, (potential energy is energy that is stored) and let's say that some wind comes through and gives that ball a push, so now the ball is moving and is going downhill. now the ball has kinetic energy because it was transferred to a moving energy from a stored energy.

2SO₂ + O₂ → 2SO₃

Donde 2 moles de SO₂ reaccionan por mol de O₂.

El peso atómico del SO₂ es:

1S = 32g/molₓ1 = 32g/mol

2O = 16g/molₓ2 = 32g/mol

SO₂ = 32g/mol + 32g/mol = 64g/mol

Y el peso atómico de O₂ es:

2O = 16g/molₓ2 = 32g/mol

Las moles de SO₂ y O₂ son:

SO₂: 40g ₓ (1mol / 64g) = 0.625 moles

O₂: 25g ₓ (1mol / 32g) = 0.7813 moles

Para una completa reacción de SO₂ se necesitan:

0.625 moles SO₂ ₓ (1mol O₂ / 2 mol SO₂) = 0.3125 moles de O₂

Así, las moles en exceso de O₂ son:

0.7813 moles - 0.3125 moles = 0.4688 moles O₂

En gramos:

0.4688 moles O₂ ₓ (32g / mol) = 15g O₂ están en exeso.

given to hospital = n / 4

given to school = 1/2 x 3n /4

= 3n / 8

given to grocer = 1 / 3 x (3n / 8 )

= n / 8

No of bags distributed

= n / 4 + 3n / 8 + n / 8

C: The surroundings heat up and the system decreases in volume.

D: The surroundings heat up and the system does not change volume.

B: The surroundings heat up and the system expands in volume.

A: The surroundings get cold and the system decreases in volume.

Explanation:

The most exothermic reactions are those that release heat, that is to say, they give up the heat as it cools and the surroundings heat up.

As for endothermics, that is, those that absorb or capture the heat of the medium, they are variables that cool the environment that surrounds them and increase their internal temperature

Answer:

Explanation:

Peter has more power, as he is able to lift the same amount of weight as Paul in a much shorter time.

If Paul can lift 100kg 10 times in 1 minute, and Peter can lift 100kg 10 times in 10 seconds, Peter is 6 times stronger than Paul, because 1 minute, or 60 seconds, is 6 times longer than 10 seconds.
