The addition of water to the solution slightly decreases the concentration of the hydrogen ion in the solution. As pH is dependent to this, it will also change. The decrease in the concentration will increase the pH value. Thus, the answer is letter B.
A condensation reaction occurs when two monosaccharide units are joined together to form a disaccharide. In the process, a water molecule is produced and lost.
The OH group of each monosaccharide are the ones that get joined to each other, with the removal of H2O. A disaccharide containing an -O- bridge between the two monosaccharides is formed.
Between glucose units, these bonds are usually between carbon 1 of one glucose molecule and carbon 4 or 6 on the other. Depending on the direction of the OH group at carbon 1, the link may be called an alpha or a beta linkage.
Answer:
Explanation:
_Andesitic__ magma is a mix between basaltic and rhyolitic magma. The eruption that would most likely result from this magma is a _strombolian____ eruption.
Andesitic magma straddles between basaltic and rhyolitic magma. They produce rocks that shows both basaltic and rhyolitic affinity. Examples of rocks that results from this type of magma is andesite.
Strombolian eruptions results from this type of magma. They are charactised by moderate to low bursts of magma. Their explosivity is between 2 and 3.
Answer: 500L
Explanation:
No of moles= volume× molarity/1000
No of moles =0.5moles
Volume=?
Molarity of a gas at stp = 1M
Stp means standard temperature and pressure
No of moles = volume ×molarity/1000
Substitute the values
0.5=volume×1/1000
Cross multiply
Volume = 1000×0.5
Volume = 500L
The volume is 500L
Answer: To determine the mole ratio
Explanation:
A balanced chemical equation is needed ,because it helps to determine the mole ratio of acid and base.
The mole ratio ensures that the number of moles of H+ provided by the acid is equal to number of moles of OH- ion provided by the base, For neutralization to occur, this must be the case.
