Select True or False: The rates of radioactive decay processes, like the rates of chemical reactions, are sensitive to temperature changes.

Answer:

yes they are same thing by E=MC^2 EINSTEIN'S EQUATION

Answer:

True.

Explanation:

The mass of these three particles is less than the mass of a neutron, so they each get some energy as well. So energy and matter are really the same thing. Completely interchangeable. And finally, Although energy and mass are related through special relativity, mass and space are related through general relativity.

So energy and matter are really the same thing. Completely interchangeable. And finally, Although energy and mass are related through special relativity, mass and space are related through general relativity. ... So in a way, energy, matter, space and time are all aspects of the same thing.

Answer:

89-91=1 the answer is 1molar mass

The correct answer is:Only statements 1 and 2 are correct.

1) The bond is planar.

2) There is free rotation about the carbonyl carbon and nitrogen bond.

The bond is planar: True, Peptide bond is a planar bond because it is composed of a double bond between the carbonyl carbon and nitrogen, and the atoms on either side of the double bond are sp2 hybridized. There is free rotation about the carbonyl carbon and nitrogen bond: True, the peptide bond between amino acids in a protein is a single bond, which allows for rotation about the bond, this is one reason proteins can adopt many different conformations.There is substantial double-bond character to this bond: False, the peptide bond is actually a single bond, although it has some double-bond character, it is not a double bond.There is a net negative charge on nitrogen and net positive charge on oxygen: False, both nitrogen and oxygen atoms in a peptide bond are neutral, as there is no charge separation in the bond.

The amount of radioactive substance has decreased from 467.8 ng to 58.48 ng after 47 days, so 2.5 half-lives have occurred.

A radioactive isotope's half-life is the amount of time it takes for one half of the radioactive isotope to decay. A specific radioactive isotope's half-life is constant; it is unaffected by conditions and is independent of the initial amount of that isotope.

Half-life = 47/2.5 = 18.8 days

Decrease in Radioactive Substance = 467.8 - 58.48 = 409.32

Half-life amount = 409.32/2.5 = 163.728

Number of half-lives = 409.32/163.728 = 2.5

A chemical equation is a graphical representation of a chemical process that employs symbols and chemical formulas. Reactant entities appear on the left, as well as product entities appear on the right, with a plus sign connecting the entities in both the reactants and the products and an arrow pointing towards the products to show the direction of the reaction.

Chemical formulae can be symbolic, structural (pictorial diagrams), or a combination of the two. The absolute values of the stoichiometric numbers are represented by the coefficients adjacent to the symbols and formulae of entities. Jean Beguin drew the very first chemical equation in 1615.

Be is the second element with two valence elements When a core electron is eliminated, the energy of ionization increases. From an element's electrical configuration, it is simple to see a significant change in ionization energy.

Electronically, beryllium is configured as 1s2 2s2. The outermost shell of beryllium has two valence electrons, hence the data on ionization energy will show a sharp rise or leap from the second to the third ionization energy due to the elimination of a core electron. Nitrogen has the following electrical configuration: 1s2 2s2 2p3. The outermost shell of nitrogen has five valence electrons, thus when one of them is removed, the ionization energy data for nitrogen will show a sharp rise or leap from the fifth to sixth ionization energy.

Answer:

the number of protons and neutrons at both terminals are equal

Explanation:

When the number of positive charge and negative charge are both equally the terminal, it becomes neutral and out of charge, because first it undergo enough chemical reaction and there is no remaining tendency for positive and negative charges to get separated. When this tendency dies, the battery also will run out of charge.

Newton's law of motion that act upon the vehicles at the point of impact is the second law of motion.

Newton's second law of motion states that the force applied to an object is directly proportional to the rate of change of momentum that is produced. Mathematically, we have;

F = m·v - m·u/Δt

Where;

m = The mass of the object

v = The final velocity of the object

u = The initial velocity of the object

Δt = The duration of motion of the object during change in velocity

Therefore, given that the mass, 'M', of the truck is larger than the mass, 'm', of the minivan, where the time of change in velocity Δt, and the initial and final velocities of both automobiles are the same such as in a sudden stop, the garbage ruck will exert more force than the minivan, and therefore, the garbage truck has a greater initial momentum before the automobiles are brought to a stop.

Answer: B, a fusion recrion creates waste material that is easier to store than fission.

Fusion produces far less harmful waste than fission does. The reliance of something independent like whether a reaction will stop on its own when something goes wrong is never indefinite (technological failures are unpredictable and destructive a lot of the time when it comes down to nuclear power).

The properties of a substance are determined by the arrangement of atoms in that substance.

A substance has two types of properties: physical and chemical properties.

The physical properties of a substance does not change the physical identity of the substance.

Examples of physical properties are density, color, boiling point, melting point and hardness.

Whereas the chemical properties are those properties which alter the substance completely and transforms it into a new substance or a compound.

For example, chemical reactions such as oxidation or reduction reactions, corrosion and flammability are chemical properties which occur when change in the arrangement of atoms take place.

Most chlorine atoms contain 18 neutrons as mole ratio of chlorine-35 and chlorine-37 is more than 1.

An atom is defined as the smallest unit of matter which forms an element. Every form of matter whether solid,liquid , gas consists of atoms . Each atom has a nucleus which is composed of protons and neutrons and shells in which the electrons revolve.

The protons are positively charged and neutrons are neutral and hence the nucleus is positively charged. The electrons which revolve around the nucleus are negatively charged and hence the atom as a whole is neutral and stable due to presence of oppositely charged particles.

let the moles of chlorine-35 is n1 and chlorine-37 is n2

now we will use the formula of average atomic mass

M=n₁M₁+n₂M₂/n₁+n₂

let say, n₁/n₂=x

substitution gives,35.45=x(35)+37/x+1 which on solving gives x=3.44

The unit of f''(a) is milliliters/minute^2

The function t=f(a) models the time, in minutes, for a chemical reaction to occur as a function of the amount a of catalyst used, measured in milliliters.

So, here double differentiation is to be done.

t=f(a)

differentiating with respect to t,

d(t)/dt = d(f'(a))/dt

or, d(f'(a))/dt = 1

again differentiating with respect to t,

d [d(f'(a))/dt]/dt = d(1)/dt = 0 ...1

or, f''(a) = 0

so, here if we put 'unit expression' in Left hand side of 1

it is d [d(f'(a))/dt]/dt  i.e.  mililiters/miniute/minute [as given t is measured in minute and f(a) is measured in ml)

or, ml/minute^2
