<u>Answer:</u> The correct answer is Option B.
<u>Explanation:</u>
Decomposition is a type of chemical reaction in which larger compound breaks down into two or more smaller compounds.
Double displacement reactions is defined as the chemical reaction in which exchange of ions takes place.
Synthesis reaction is a type of reaction in which two or more smaller compounds combines to form a single large compound.
Single displacement reaction is a type of reaction in which a more reactive metal displaces a less reactive metal from its chemical reaction.
In stomach, an acid is present known as hydrochloric acid and to neutralize its effect, antacid is taken which has 
as a component.
The reaction between HCl and 
is a type of neutralization reaction and it is a type of double displacement reaction.
The equation between the two follows:
Hence, the correct answer is Option B.
Answer:
state of matter
Explanation:
so take water for example, water has a melting point and a boiling point right? So if it's below 0 degrees, then it's in its solid phase. If the temperature is above 0 degrees, then the water starts to melt into its liquid phase. Then when the temperature is above 100 degrees, water starts to boil and become its gas phase. This is the same for all substances. The only difference is different substances have different melting and boiling points so the numbers will be different depending on your substance. hope this helped!
Answer:
Biochemical compounds make up the cells and other structure of organism and carry out life processes.Carbon is the basic of all biochemical compounds so carbon carried life process on the earth
Answer:
Explanation:
Since we are given the mass, specific heat, and temperature, we should use the following formula for heat energy.
The mass of the aluminum is 26.3 grams. Its specific heat is 0.930 Joules per gram degree Celsius. We need to find the change in temperature.
- The change in temperature is the difference between the initial temperature to the final temperature.
- The temperature changes <em>from</em> 23.0°C <em>to</em> 67.0°C, so the initial is 23 degrees and the final is 67 degrees.
- ΔT= final temperature - initial temperature
- ΔT= 67°C - 23°C
- ΔT= 44°C
Now we know all the values.
- m= 26.3 g
- c= 0.930 J/g °C
- ΔT= 44°C
Substitute the values into the formula.
Multiply the first two numbers together. The units of grams cancel.
Multiply again. This time, the units of degrees Celsius cancel.
<u>1076.196 Joules</u> of heat will be absorbed by the piece of aluminum.
