In order to satisfy charge conservation and lepton number conservation the other products must be neutron.

The principle of conservation of mass states that, the sum of the initial mass of reactants must be equal to final mass of the products.

[tex]_{15}^{30}P\ --- > \ _{14}^{30} Si \ + \ ^{0}_{1} n[/tex]

The balanced reaction of radioactive decay of phosphorous shows conservation of mass.

Thus, in order to satisfy charge conservation and lepton number conservation the other products must be neutron.

Molarity is the ratio of the moles and the volume. The mass of 2.6 M sodium phosphate solution is 2131.22 gms.

Mass is the product of the moles and the molar mass of the substance. It is given as,

Mass = Moles × Molar mass

The moles from molar concentration is used to calculate mass as:

Mass = Molarity × volume × molar mass

= 2.6 × 5.0 × 163.94

= 2131.22 gms

Therefore, 2131.22 gms is the mass of sodium phosphate.

Dust clouds that moved to the east coast of the united states were composed mostly of silt and clay particles due to constant ploughing during drought.

This is defined as dry period in the climate due to insufficient rainfall in the area at a given time.

The drought led to the soil being constantly ploughed thereby loosening and changing the soil type which is susceptible to wind erosion.

Answer:

During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil

The heat produced when iron oxide reacts with carbon monoxide is -23.47 kJ/mol.

The standard enthalpy of the reaction is given by the enthalpy of formation of the products and the reactants. The reactants and the products of the reaction are:

Fe₂O₃ (s) + 3CO (g) → 2Fe(s) + 3CO₂ (g)

We know,

The standard enthalpy of formation of iron oxide = −825.50 kJ/mol

The standard enthalpy of formation of carbon monoxide = −110.53 kJ/mol

The standard enthalpy of formation of carbon dioxide = −393.52 kJ/mol

The standard enthalpy of reaction is calculated as:

[tex]\rm \Delta H_{rxn}[/tex] = [2(0) + 3(−393.52)] - [1(-825.50) + 3(-110.53)]

= (0−1180.56+825.50+331.59)

= −23.47 kJ/mol

Therefore, −23.47 kJ/mol is produced.

Copper is a soft, ductile, and malleable metal that bends and stretches easily without breaking. Copper is a versatile metal for construction and manufacturing because of this.

Answer:

it is because of the bacteria and different things that go into waters such as ponds, rivers, lakes, seas, oceans, streams, and other body of waters and I should also add the chemicals that go into them as well

Explanation:

It can be said that water will take more heat to raise its temperature by 1°C than copper. Details about specific heat can be found below.

Specific heat capacity of a substance can be defined as the amount of heat (J) absorbed per unit mass (kg) of the material when its temperature increases 1 K or 1 °C.

According to this question, water has a specific heat of 4.184 J/g°C while Copper metal has a specific heat of 0.385 J/g°C. This shows that water has a higher specific heat.

Therefore, it can be said that water will take more heat to raise its temperature by 1°C than copper metal.
