A sample of vinegar has a hydronium concentration of 1.6 × 10-3 M. What is the pH of the vinegar?
loris [4]
PH is defined as the negative log of Hydronium Ion concentration.

So, in order to find the pH of vinegar, we find the negative log of its hydronium ion concentration.

pH=-log[ H_{3}O^{+}] \\  \\ 
pH=-log(1.6  * 10^{-3})  \\  \\ 
pH=2.8

So, the pH of given vinegar solution will be 2.8.

Therefore, the answer to this question is option B

a chemist measured 75.00g of HCL into a volumetric flask and added water until the volume was 1.000 L. what is the molarity of t
Aleks04 [339]

Answer: M = 2.08 M

Explanation: Molarity is expressed as the number of moles per unit volume in liters. First convert the mass of HCl to moles using its molar mass. Then substitute the variables to the formula for molarity.

75.00 g HCl x 1 mole HCl / 36 g HCl

= 2.08 moles HCl

For Molarity.

M = n / L

= 2.08 moles HCl / 1.000 L

= 2.08 M

Displacement is the slope of a velocity vs. time graph<br><br> A. True<br><br> B. False
mezya [45]

Answer:

The given statement is false.

Explanation:

Displacement is a vector quantity which represent shortest distance form initial position to final position.

Velocity of an object is defined as ratio of displacement of object to that of the time taken by object to move from its initial position to final position.

In displacement vs time graph the slope of the graph represent the velocity. Whereas slope of velocity vs time graph gives acceleration.

How many valence electrons are in Tc
mixer [17]
Tc is Technetium, and it has an atomic number of 43. Its atomic configuration is [Kr] 5s(1) 4d(5) [I'm on my phone so I can't do numbers on shoulders, pretend that 1 and 5 are on the s and d's shoulder]
The outside most ring is the 4d(5), and the d orbital can hold ten electrons.
Valence electrons are electrons, in you could say the outside ring that isn't filled, the extra ones. In this case, there are 5.

HELP i need the answer to this science question:
S_A_V [24]

Answer:

1. Convection: c. Transfer of energy by movement of matter.

2. Radiation: e. Transfer of energy by waves, often through empty space.

3. Thermal Energy: a. The total energy an object has. The more stuff you have the higher this will be.

4. Conduction: d. Transfer of energy by contact between two things.

5. Heat: b. Any transfer of thermal energy

______________________

<h2>Explanation(s):</h2>

<u>Explanation of #1</u>:

Convection is one of the three ways thermal energy is transferred. Convection is usually defined as the transfer of heat by the circulation or movement of the heated parts of a liquid or gas. An example of convection on earth is convection currents. Convection currents are the movement of fluid as a result of differential heating or convection. In the case of the Earth, convection currents refer to the motion of molten rock in the mantle as radioactive decay heats up magma, causing it to rise and riving the global-scale flow of magma.

<u>Explanation for #2:</u>

Electromagnetic waves are waves produced the acceleration of an electric charge and propagated by the periodic variation of intensities of, usually, perpendicular electric and magnetic fields. This transfer of energy by waves is known as radiation. Or in other words, this kind of transfer is done through the propagation of electromagnetic waves, that carry energy, without need of a material medium, in empty space. Radiation is usually defined as the complete process in which energy is emitted by one body, transmitted through an intervening medium or space, and absorbed by another body.

<u>Explanation for #3</u>:

Thermal energy can be defined in 3 different ways. First, it can be defined as the internal energy of a system in thermodynamic equilibrium due to its temperature. Second, A form of energy; sensible energy; heat. Third and last, the energy released by an explosion. Thermal energy is produced through the movement of particles within a system or object, it can be referred to as kinetic energy. Kinetic energy is usually defined as the energy of a body or a system with respect to the motion of the body or of the particles in the system.

<u>Explanation of #4</u>:

Conduction is usually defined as the transfer of heat between two parts of a stationary system, caused by a temperature difference between the parts.  Conduction is the transfer of heat through direct touch of molecules. Conduction is the transfer of thermal energy with no transfer of manner. It occurs when two materials touch. The heat movement in conduction is within and via the body itself. In contrast, heat transmission through thermal radiation frequently occurs between entities that are geographically separated. Heat can also be transferred by a mix of conduction and thermal radiation.

<u>Explanation of #5</u>:

As a noun, heat is usually defined as the state of a body perceived as having or generating a relatively high degree of warmth. There are 3 types of ways heat can be transferred which is via conduction, convection, or radiation. Heat produces thermal energy which is transmission through these 3 different processes. Thermal energy is the internal energy of a system in thermodynamic equilibrium due to it's temperature. Thermal energy is produced through heat and is transmission through the 3 processes in different ways (mentioned above obviously).

<h3>additional comment:</h3>

Definitions:

Radiation is simply the energy that is emitted by a body that has energy. Even human beings radiate energy (infra red radiation).

Convection is the transfer of heat through fluid (liquid or gas). It probably relates to astronomy in that due to gravity, a star's core is much hotter than the rest of it. The heated plasma rises to the surface like boiling water, where the heat is absorbed by the surrounding plasma through convection , then it cools and sinks down to the core again.

In the atmosphere conduction is the transfer of heat by direct contact. The best example would be the heating of the atmosphere that is directly in contact with the Earth (first few feet).

On a particle level this is energy transferred by the particles colliding with and passing energy into adjacent particles.
