What is the relationship between the concentration and the rate of the reaction?
negative
neutral
positive
Answers
Answer:
When the concentration of all the reactants increases, more molecules or ions interact to form new compounds, and the rate of reaction increases. When the concentration of a reactant decreases, there are fewer of that molecule or ion present, and the rate of reaction decreases.

Which ion has the correct charge?
07-
Na 2+
N 3+
Ca2+
Answers
Answer:
Ca(2+)
Explanation:
Sodium (Na) only have one valence electron and will lose it in order to gain a full octet. There will be an unbalance of electrons and protons where there are more protons there electrons. The correct ion formula for sodium is Na (1+).
Nitrogen has 5 valence electrons and will gain three more to gain a full octet. There will be an unbalance where there are more electrons then protons. Nitrogen will form the ion N (3-).
Calcium has two valence electrons and will lose them in order to gain a full octet. There will be an unbalance where there are more protons then electrons. Calcium will form the ion Ca 2+
Therefore, Ca2+ is the ion with the correct charge.

Voltage ______
Question 1 options:
causes current
pushes free electrons around a circuit
is measured in Volts
all of the choices
Answers
Explanation:
When a voltage source is connected to a circuit, the voltage will cause a uniform flow of charge carriers through that circuit called a current.
Voltage is the pressure from an electrical circuit's power source that pushes charged electrons (current) through a conducting loop, enabling them to do work such as illuminating a light.
In brief, voltage = pressure, and it is measured in volts (V).

During an experiment, a canister filled with hot water was added to a beaker filled with cold water. In which direction did the heat energy move?
A) The heat energy moved from the hot water of the canister into the cold water of the beaker.
B) The heat energy moved from the cold water of the beaker into the hot water of the canister.
Equal amounts of heat energy from each container moved in both directions
D) No heat energy moved, as it all remained in the canister of hot water.
Answers
Answer:
A
Explanation:
As per the concept of thermal energy, heat energy will be moved from hot water of canister to cold water of beaker as heat flows from point at high temperature to point at lower temperature.
What is thermal energy?Thermal energy is defined as a type of energy which is contained within a system which is responsible for temperature rise.Heat is a type of thermal energy.It is concerned with the first law of thermodynamics.
Thermal energy arises from friction and drag.It includes the internal energy or enthalpy of a body of matter and radiation.It is related to internal energy and heat .It arises when a substance whose molecules or atoms are vibrating faster.
These vibrating molecules and atoms collide and as a result of which heat is generated in a substance , more the collision of particles , higher is the thermal energy.

Vinegar is an ingredient commonly used by chefs. Scientists also use it as well, although they call it acetic acid. When vinegar is in its liquid or solid (frozen) states, it has a fixed volume. But when vinegar is in its gas state, it takes up the entire volume of whatever container it is in. This is why you can smell an open bottle of vinegar the minute you walk into a kitchen, even though you cannot actually see the gas particles!
Which statement best explains why the volume of vinegar gas is changeable as opposed to the fixed volume of its solid and liquid states?
A. Gas particles are always at a higher pressure than solids and liquids.
B. Gas particles are always at a higher temperature than solids and liquids.
C. Gas particles are spaced far apart and can move freely.
D. Gas particles stay close together but can move around each other.
Answers
Answer: C
Explanation: Because gas particles are free to move fast where as liquid can move a little but solid cant so it would be C
