Explanation:
The Kinetic Molecular Theory describes the behavior as well as the characteristics of an ideal gas. What are the five postulates of this theory? Provide at least 3 examples to describe these postulates.
Answers
Answer:
See explanation
Explanation:
The postulates of the kinetic theory of matter are;
Every substance is made up of tiny particles called molecules. Brownian motion and diffusion illustrates this fact.The molecules that compose matter are in constant random motion.There exists an attractive force between the molecules in matter. The attractive forces between gases are negligible. Solids have a definite shape and volume due to a high magnitude of intermolecular forces. Liquids have a volume but no definite shape due to weaker intermolecular forces. Gases have the weakest intermolecular forces hence the do not have both a shape and volume. They take on the volume of the container into which they are put. This illustrates this fact.The actual volume occupied by gas molecules is negligible relative to the volume of the container. The fact that gases are easily compressible illustrates this fact.Temperature is a measure of the average kinetic energy of the molecules of a body.answer 1-5 of lesson outline for brainiest

Question 19 (3 points)
If the density of the earth was 11.0 g/mL instead of its measured value of 5.51 g/mL, the force of gravity would
be twice what it is at sea level. If the earth's density was twice than its actual density, then in pounds per
square inch at sea level the earth's atmosphere in British units would be equal to:
a) 7.35 psi b) 14.7 psi c ) 29.4 psi d) 44.1 psl e) 98.8 psi
Answers
Answer:
c ) 29.4 psi
Explanation:
If the density of earth was twice than its actual density which is 5.51 g/mL, then at sea level the atmospheric pressure of earth in British units would be equal to 29.4 psi because increase of gravity, increase occurs in the atmospheric pressure. If we double the gravity of earth by double of the earth density, so the weight of that same mass of air will be double which leads to the doubling of the atmospheric pressure at the sea level.

A drought hits the habitat of a semi-aquatic bird population. All ponds dry up, and fish populations decline. There are two groups of birds in the population that differ in leg length and diet. Long-legged birds eat fish, while short-legged birds eat insects. The drought has little effect on insect populations.
Answers
Answer:
The population of the long-legged birds decreases.
Explanation:
The population of the short-legged birds increases whereas the population of long-legged birds decreases due to availability of food in that environment. The long-legged birds feed on fish whose population decreases due to drought conditions so the population of long-legged birds also decreases while on the other hand, the population of short-legged birds increases or remain the same because they feed on the insects and the insects are available in large amount and less affected by the drought conditions.

. I am described as being conductive, malleable, shiny, and reactive with HCl. I am one of the most reactive elements. I turn black within seconds when I am exposed to air. If someone drops water on me, I will explode. When I do explode I send off characteristic purple-red (violet) flame. Who am I?
Answers
Answer:
Potassium
Explanation:
Most reactive metal in the reactivity series
The element in the question is referred to the alkali metal which is known as Potassium
Potassium is a highly reactive metal and reacts with Hydrochloric acid to
form a salt known as Potassium chloride and hydrogen gas.
Hcl + K ⇒ Kcl₍s₎ + H₂₍g₎
Potassium has a white color but when it reacts with water it explodes and
gives out a purple-red color as a result of the high excitation of electrons.

A. Particle emitted = alpha particle; Protons lost = 2; Change in mass = -4
B. Particle emitted = alpha particle; Protons lost = 2; Change in mass = -4
C. Particle emitted = beta particles; protons gained = 1; Change in mass = 0
D. Particle emitted = alpha particle; Protons lost = 2; Change in mass = -4
E. Particle emitted = gamma ray; protons gained = 0; Change in mass = 0
F. Particle emitted = alpha particle; Protons lost = 2; Change in mass = -4
Explanation:
Radioactivity is the spontaneous disintegration of nucleus of an atom resulting in emission of particles and radiation unyil a stable atomic nuclei is obtained. Substances that are exhibit radioactivity are known as radioactive substances and are usually isotopes of stable atoms.
The types of radiation emitted by a radioactive substances include alpha rays, beta rays, and gamma rays.
Alpha rays or particles are fast moving positively charged particles with a mass number of four and atomic number of two. Thus, each alpha particle is a helium nucleus.
Beta rays or particles are vary fast moving stream of electrons having a mass number of zero and a charge of -1.
Gamma rays are not particles but are electromagnetic waves similar to visible light and X-rays but with shorter wavelengths. They have no mass or charge.
An atom emitting alpha particles has its mass reducing by 4 units and its atomic number decreasing by 2.
An atom emitting beta particles as it decays has no change in mass but its atomic number increases by 1.
From the table:
A. Particle emitted = alpha particle; Protons lost = 2; Change in mass = -4
B. Particle emitted = alpha particle; Protons lost = 2; Change in mass = -4
C. Particle emitted = beta particles; protons gained = 1; Change in mass = 0
D. Particle emitted = alpha particle; Protons lost = 2; Change in mass = -4
E. Particle emitted = gamma ray; protons gained = 0; Change in mass = 0
F. Particle emitted = alpha particle; Protons lost = 2; Change in mass = -4

An unknown piece of metal absorbs 1350 J of heat as 55.0 g of the metal heats up from 20.0 oC to 47.0 oC
Answers
Answer:
[tex]C=0.91\frac{J}{g\°C}[/tex]
Explanation:
Hello there!
In this case, according to the given information, it is possible to recall the equation to calculate the heat, Q, in these calorimetry problems as shown below:
[tex]Q=mC(T_f-T_i)[/tex]
Thus, given the absorbed heat, mass and temperatures, we can easily calculate the specific heat of the metal as shown below:
[tex]C=\frac{Q}{m(T_f-T_i)}[/tex]
Then, by plugging in we obtain:
[tex]C=\frac{1350J}{55.0g(47.0\°C-20.0\°C)} \\\\C=0.91\frac{J}{g\°C}[/tex]

Define respiration in plants:
Define Transpiration in plants:
( Can’t be short has to at least be long or medium sized )
Answers
Answer:
Respiration in plants: The process of respiration in plants involves using the sugars produced during photosynthesis plus oxygen to produce energy for plant growth. In many ways, respiration is the opposite of photosynthesis. ... As with photosynthesis, plants get oxygen from the air through the stomata.
Transpiration in plants: The water eventually is released to the atmosphere as vapour via the plant's stomata — tiny, closeable, pore-like structures on the surfaces of leaves. Overall, this uptake of water at the roots, transport of water through plant tissues, and release of vapour by leaves is known as transpiration.

You have to make 500 mL of a 1.50 M BaCl2. You have 2.0 M barium chloride solution available. Determine how to make the needed dilution
Answers
Answer:
You need 375 mL of BaCl2 solution.
Explanation:
M1V1=M2V2
Dilution formula. Substitute known values and solve for V1.
M1 = 2.0 M
M2 = 1.50 M
V2 = 500 mL
(2.0 M)(V1) = (1.50 M)(500 mL)
V1 = (1.50 M)(500 mL) / (2.0 M)
V1 = 375 mL
