What it’s used to determine the number of each atom in an ionic formula

Gala2k [10]

Answer:

If the electronegativity difference is greater than 2.0, then the bond is ionic.

Explanation:

For ex:

Na has the electronegativity of 0.93

Cl has the electronegativity of 3.16

we subtract 3.16-0.93

We have 2.23 electronegativity difference between Na and Cl

because 2.23 > 2.0

therefore NaCl compound has an ionic bond.

If a particle has Z = 25 and 23 electrons, what is its charge?

Anton [14]

Answer:- The charge is +2.

Explanations:- Z stands for atomic number. The Z is given as 25 means the atomic number of the element is 25. It has 23 electrons. For a neutral atom the number of electrons is same as the atomic number. Since the number of electrons is less than atomic number, the atom must have lost the electrons.

Number of electrons lost = 25 - 23 = 2

If the element lost electrons then it has positive charge. As, the electrons are lost, the charge is +2.

Which diagram shows a wave with the highest frequency? Chemistry question.

notsponge [240]

The correct answer is D

Explanation:

Wave frequency is mainly determined by the number of waves that pass through a specific point. In a diagram, this can be found by analyzing the number of crests (top of the wave) and the space between them. For example, wave B is the one with the lowest frequency because there is only one crest and this shows only one wave passing at a specific point. On the opposite, wave D is the one with the highest frequency because this shows multiple crests and this indicates the frequency is high or that many waves pass through a specific point in a short time.

The heat capacity of water is 1cal degree'g1 (1 calorie per degree centigrade, per gram). You are given 1 gallon of water at 25

sdas [7]

Answer:

The heat needed to boil 1 gallon of water is 81,490.62 Joules.

Explanation:

$Q=mc\Delta T$

Where:

Q = heat absorbed or heat lost

c = specific heat of substance

m = Mass of the substance

ΔT = change in temperature of the substance

We have :

Volume of water = V = 1 gal = 4546.09 mL

Density of water , d= 1 g/mL

mass of water = m = d × V = 1g/mL × 4546.09 mL = 4546.09 g

Specific heat of water = c = 1 Cal/g°C

ΔT = 100°C - 25°C = 75 °C

9 (boiling pint of water is 100°C)

Heat absorbed by the water to make it boil:

$Q= 4546.09 g\times 1 Cal/g^oC\times 75^oC=340,956.75 Cal$

1 calorie = 4.184 J

$Q=\frac{340,956.75}{4.184} J = 81,490.62 J$

The heat needed to boil 1 gallon of water is 81,490.62 Joules.
