To clean their drain pipes, some people make a solution of baking soda and vinegar. Baking soda, also known as sodium bicarbonate (NaHCO3), reacts with acetic acid (C2H4O2) in vinegar. When these substances combine, the solution becomes colder, and sodium acetate (NaC2H3O2), water (H2O), and carbon dioxide gas (CO2) form. The gas creates bubbles that help clean the inside of the pipes. is this reaction endothermic or exothermic?
Answer:
i belive its exothermic

Answer:
Lightning rods (and the accompanying protection system) are designed to protect a house or building from a direct lightning strike and, in particular, a lightning-initiated fire, Static electricity is the result of an imbalance between negative and positive charges in an object. These charges can build up on the surface of an object until they find a way to be released or discharged. One way to discharge them is through a circuit, and An electroscope is an early scientific instrument used to detect the presence of electric charge on a body. It detects charge by the movement of a test object due to the Coulomb electrostatic force on it.

Researchers have been studying how emissions from both volcanoes and human activities, such as the burning of fossil fuels, impact the atmosphere. Both types of emissions contribute to the total CO2 levels in the atmosphere. Graph 2 shows that atmospheric CO2 levels have been steadily increasing over time. This increase in CO2 levels has been linked to the increase in global surface temperatures.
Identify the part of the slow carbon cycle in which the total amounts of carbon is most likely decreasing the most and explain why this decrease occurs.
Answer:
Over the last century the burning of fossil fuels like coal and oil has increased the concentration of atmospheric carbon dioxide (CO2). This happens because the coal or oil burning process combines carbon with oxygen in the air to make CO2. as u know decreasing means going down and increasing means going up. the reason why things decrease means something went wrong or something to happen to make it go down we all try to make things increase which means we try to make things go up instead of down. a lot of reasons is y things decrease is bc during the period of time something might go wrong or happen in a bad way that makes a lot of things decrease. for example like temperature when the temperature decreases it means it goes down and it might get cold but if the temperature increases it goes up so it might be ht or warm or maybe even cool. if something ever decreases it means during the period of time something bad happened and made it go down instead of up if something ever goes wrong that means something decreased. sometimes decreasing could be a good thing but most of the time it it bad but there are sometimes when decreasing is good but not all the time.
The part of the slow carbon cycle in which the total amounts of carbon is most likely decreasing the most is from 1960 to 1970.

A lot of reasons is why things decrease is because during the period of time something might go wrong or happen in a bad way that makes a lot of things decrease. For example, Temperature. When the temperature decreases it means it goes down and it might get cold but if the temperature increases it goes up so it might be hot or warm or maybe even cool. If something ever decreases it means during the period of time something bad happened and made it go down instead of up if something ever goes wrong that means something decreased.

Jennifer is applying a constant force to swing a can on the end of a string, as shown here. If the can is moving around the circle at a constant speed, which statement correctly describes the motion of the can?
A.
The can accelerates at every point along the orbit and has changing velocity.
B.
The can has constant acceleration and changing speed.
C.
The can has constantly changing acceleration.
D.
The can moves at a constant velocity.
The statement that correctly describes the motion of the can is D. that the can move at a constant velocity.
Based on the information given, Jennifer is applying a constant force to swing the can. In this case, the force that's being acted on the can is at an unchanging rate.Also, the can is moving around the circle at a constant speed. This implies that the speed of the car reasons the same as it's neither increasing nor decreasing.Based on the information given above, since a constant force is applied by Jennifer, and the can is also moving at a constant speed, then the can move at a constant velocity.

Which is one characteristic that temperate marine and temperate continental climates have in common?
mild winters
hot summers
many tall trees
moderate amounts of precipitation
Answer: D : moderate amounts of precipitation
Explanation:
The one characteristic that temperate marine and temperate continental climates have in common is moderate amounts of precipitation. Thus, the correct option for this question is D.
What is Climate?Climate may be characterized as the long-term pattern of weather in a particular area. It is different from the weather in a way that can change from hour to hour, day-to-day, month-to-month, or even year-to-year.
According to the context of this question, A maritime climate is influenced by a nearby ocean. A continental climate is influenced by nearby land. The temperature of offshore currents affects nearby land areas.
A maritime climate is less extreme than a continental climate because the ocean moderates temperatures. Due to this, both temperate marine and temperate continental climates have moderate amounts of precipitation.
Therefore, the correct option for this question is D.

Answer:
Like magnetic poles repel each other
Explanation:
Among the following statements, the one that is true is Like magnetic poles repel each other.
What are magnets?Magnets are substances which possess their own magnetic field this magnetic field basically arises from the circular movement of negatively charge electrons. The elements which have unpaired electrons and have spin angular momentum or orbital angular momentum or they are together present are called as Magnets.
The magnetic field present is invisible but it is definitely responsible for the most notable property of a magnet. Magnetic force is a force that pulls on other ferromagnetic materials, such as iron, steel, nickel, cobalt, etc. and attracts or repels other magnets.

Explanation:

According to the concept of solubility, carbonic acid is a mixture of water and carbon dioxide.
Solubility is defined as the ability of a substance which is basically solute to form a solution with another substance. There is an extent to which a substance is soluble in a particular solvent. This is generally measured as the concentration of a solute present in a saturated solution.
The solubility mainly depends on the composition of solute and solvent ,its pH and presence of other dissolved substance. It is also dependent on temperature and pressure which is maintained.Concept of solubility is not valid for chemical reactions which are irreversible. The dependency of solubility on various factors is due to interactions between the particles, molecule or ions.
A mixture of water and carbon dioxide under high temperature and pressure forms carbonic acid as it is highly soluble,thus carbonic acid is a mixture of water and carbon dioxide.
