What is hybrid orbitals?Hybrid orbitals are defined as the outcome of a model that generates a new set of orbitals by combining atomic orbitals on a single atom.
It can also be defined as a form of atomic orbital that emerges when two or more atomic orbitals of an isolated atom mix.
It can be defined as the forming new atomic orbitals by combining two or more common atomic orbitals.
The process which forms hybrid orbitals are known as hybridization.
There are mainly five types of hybridization.

How much heat is necessary to 20g of water at 100*C into steam at 100*C?
Answer:
To convert 100.0 g of water at 20.0 °C to steam at 100.0 °C requires 259.5 kJ of energy.
The amount of heat which is required for a phase change of a substance without any change in temperature is known as latent heat. Here the amount of heat required is 10,800 calories.
What is heat capacity?The heat capacity of a substance or a system is defined as the amount of heat required to raise its temperature through 1°C. It is denoted by C. The specific heat capacity is the amount of heat required to raise the temperature of 1 gram of the substance through 1°C.
The equation to calculate the heat required is:
Q = mc (T₂ - T₁) + mL₁
L = Latent heat of vaporization of water
m = mass
c = specific heat capacity
T₂ = Final temperature
T₁ = Initial temperature
T₂ - T₁ = 100 - 100 = 0°C
Q = 20 g × 1 cal /g°C × 0°C + 20 g × 540 cal/g
Q = 10,800 calories
Thus the amount of heat required is 10,800 calories.

Calculate the heat produced by hydrolysis of 65 kg of ATP (the molecular weight of ATP is 507.18 g/mol).
The heat produced by hydrolysis of 65 kg of ATP is -6.8 kJ.
Let's consider the thermochemical equation for the hydrolysis of ATP.
ATP + H₂O ⇒ ADP + Pi ΔG = -57 kJ/mol
We will convert 65 kg of ATP to moles using its molecular weight (507.18 g/mol).
[tex]65 \times 10^{3} g \times \frac{1mol}{507.18g} = 1.2 \times 10^{2} mol[/tex]
57 kJ of heat are released by the hydrolysis of 1 mole of ATP. The heat released by the hydrolysis of 1.2 × 10² moles of ATP is:
[tex]1.2 \times 10^{2} mol \times \frac{(-57kJ)}{1mol} = -6.8 \times 10^{3} J = -6.8 kJ[/tex]
-6.8 kJ is the heat produced by hydrolysis of 65 kg of ATP.

A 200.0 ml beaker filled with oil has a mass of 293.2 g. The mass of just the beaker is 130.2
g. What is the density of the oil?
Answer in a complete sentence. Show your work. Your final answer should have the cor-
rect number of sig figs. show work!
Answer:p=m/v
p=(292.2-130.2)/200
p=0.8100g/ml
Explanation:
Density of a substance is the ratio of its mass to volume. The density of the oil filled in a 200.01 ml beaker is 0.815 g/ml.
What is density?Density of a substance is the mass per volume. Thus we het how much of its particles are located per one unit of volume.
Mathematically density can be written as mass/ volume. The mass of the beaker containing oil is given as 293.2 g. The mass of beaker itself is 130.2 g. Hence, mass of oil is 293.2 - 130.2 = 163 g.
Volume of the oil is 200 ml. Thus density is 163 g/200 ml = 0.815 g/ml.
Hence, the oil in the beaker with 200 ml volume and 163 g mass have a density of 0.815 g/ml.

Convection currents in the atmosphere influence many weather patterns. What property of the air has the most influence on convection currents?
1. The direction of the wind
2. The velocity of the wind
3. The temperature of the air
4. The mass of the air
Convection currents are largely influenced by air temperature. A low-pressure area is produced when air is heated because it becomes less dense and rises.
What effect on the climate does convection have?For instance, the air above the Earth heats and rises as its surface warms from the sun. This air may continue to rise while cooling and producing cumulus clouds if the conditions allow.
How do air masses respond to convection currents?Climate-affecting wind patterns are driven by convection currents. Convection currents are used to shift air masses. There are two different kinds of air masses: warm and cold. From higher latitudes to lower latitudes, cold air masses travel.

d. Electrons lose energy as they travel around the nucleus
e. Each energy level has a specific energy value
The model of Neils Bohr postulates that electrons in atoms are found in specific energy levels. Transition from a higher to a lower energy level produces an emission spectrum characteristic of elements.
According to Bohr's model of the atom, an electron in atom exists in distinct energy levels. Electrons can be promoted from lower to higher energy levels when they absorb energy. The electrons are unstable in this higher energy excited state hence they quickly return to the ground state emitting energy. This emission is characteristic of elements.
