Answer:
A neutral atom have equal number of proton and electron. In other words we can say that negative and positive charges are equal in magnitude and cancel the each other and atom become neutral.
Explanation:
An atom consist of electron, protons and neutrons. Protons and neutrons are present with in nucleus while the electrons are present out side the nucleus.
All these three subatomic particles construct an atom. A neutral atom have equal number of proton and electron. In other words we can say that negative and positive charges are equal in magnitude and cancel the each other and atom become neutral. For example if neutral atom has 6 protons than it must have 6 electrons. The sum of neutrons and protons is the mass number of an atom while the number of protons are number of electrons is the atomic number of an atom.
For example
The carbon have six protons and six neutrons so its atomic mass is 12 amu and atomic number is six.
The correct answer is 221.06 °C hot.
If P₁ is the pressure at T₁ and P₂ is the pressure at T₂ then,
P₁/T₁ = P₂/T₂
It is given that P₁ = 2.38 atm
T₁ = 15.2 degree C = 273 + 15.2 = 288.2 K
P₂ = 4.08 atm
T₂ = x
Thus, 2.38 / 288.2 = 4.08 / x
x = (4.08 × 288.2) / 2.38
x = 494.06 K
x = 494.06 - 273 °C = 221.06 °C
Therefore, the tire would get 221.06 °C hot.
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.
Answer:
Reducing molecules.
Explanation:
NAD (Nicotinamide adenine dinucleotide) is the important molecule used by the living organisms for the generation of ATP. NADH is used almost in every biochemical cycle like glycolysis, kreb cycle and elelctron transport chain.
The NADH molecule is used as the reducing molecule in the biosynthesis of the different reaction. The NADH molecule reduces its hydrogen ions and also carry electrons for the synthesis of molecules. The NADH molecule is also used in the shuttle system as well.
Thus, the answer is reducing molecules.
Without the carbon cycle we wouln't have air to breathe, we would die due to the lack of air.
Plants use carbon dioxide and sunlight to make their own food and grow. The carbon becomes part of the plant. Plants that die and are buried may turn into fossil fuels made of carbon like coal and oil over millions of years. When humans burn fossil fuels, most of the carbon quickly enters the atmosphere as carbon dioxide.
