Alka-seltzer in an antacid that contains a mixture of sodium bicarbonate and citric acid. When the tablet is dissolved in water, the reactants which are in solid form in tablet become aqueous and react with each other.
During this reaction, Carbon Dioxide gas is evolved which causes the reaction mixture to fizz. The equation is given below.
Rate of the above reaction is affected by the Temperature.
As the temperature increases , the rate of the reaction increases. This happens because at higher temperature, the collisions between reacting species are more which result in formation of product in less time. This increases the rate of reaction.
We have been given equal volumes of water for each beaker. But the temperature of beaker c is 80°C which is the highest temperature. That means the reaction in beaker c is fastest.
Whereas beaker a is at lowest temperature (30°C) , therefore the reaction in beaker a would be slowest .
Therefore the answer that correctly orders the reaction rates from fastest to slowest reaction is beaker c > beaker b > beaker a
Answer:
Adiabatic temperature changes.
Explanation:
Temperature changes related to changes of pressure without external gain or loss of heat. If no heat is added or lost to the surroundings, then when an air parcel rises and expands, its temperature drops. Conversely, when the parcel is compressed, its temperature rises. So the term adiabatic, implies a change in temperature of the air parcel without gain or loss of heat from outside the air parcel.
Answer:
Explanation:
iron is element number 26 this means that it has 26 number of electron and proton in its atomic structure so its atomic number is 26
C. Shape, because increasing pressure has a profound influence on the volume of a gas sample, for example, it pushes the particles closer together; thus gases are considered compressible.
Answer:
, CaCO3, contains one atom of calcium, one of carbon and three of oxygen. so t<u>here are 5 atoms in CaCO3</u>
Mg(OH)2, There is one magnesium, two oxygen, and two hydrogen atoms. so <u>there are 5 atoms Mg(OH)2</u>
a molecule of acetic acid contains two carbon atoms, four hydrogen atoms, and two oxygen atoms. <u>so there are 8 atoms in acetic acid </u>
There are <u>3 atoms in CaCl2</u>
H2SO4 is a chemical compound made up of two hydrogen atom, one sulfer atom, and four oxygen atoms. <u>So there are 7 atoms in H2SO4</u>
There are <u>8 atoms in sodium phosphate</u>
