A single replacement reaction
<h3>Further explanation
</h3>
There are two types of chemical reactions that may occur.
namely single-replacement reactions and double-replacement reactions.
A single replacement reaction is a chemical reaction in which one element replaces the other elements of a compound to produce new elements and compounds
Not all of these reactions can occur. We can use the activity series, which is a list of elements that can replace other elements below / to the right of them in a single replacement reaction.
This series is better known as the Volta series, where the metal element with a more negative electrode potential is on the left, while the element with a more positive electrode potential on the right.
The more left the position of a metal in the series, the more reactive metal (easy to release electrons, the stronger as the reduction agent)
The metal activity series is expressed in voltaic series
<em>Li-K-Ba-Ca-Na-Mg-Al-Mn- (H2O) -Zn-Cr-</em><em>Fe</em><em>-Cd-Co-Ni-Sn-Pb- (H) -</em><em>Cu</em><em>-Hg-Ag-Pt-Au </em>
Fe(more active element) takes the place of Cu(less reactive element) in the CuSO4 compound
Air does move from high to low pressure so true
Hello!
For this reaction: 2H
₂ + O₂ → 2H₂O
If 19 g of oxygen reacts completely,
you'll need 2,39 g of H₂
To calculate that, you need to use the following conversion factor, applying molar equivalences, reaction coefficients, and molar masses, to go from grams of Oxygen to grams of Hydrogen:
Answer:
True.
Explanation:
Barbiturates belong to the class of sleep inducing chemicals. Alcohol and barbiturate are addictive in nature and the individuals cannot easily get rid of these addiction.
Proper treatment and rehabilitation centers are required for the treatment of addicted people. Direct withdrawal from these activities increase the chances of risk as the body is not able to become normal. The body start producing harmful chemicals even in the absence of alcohol.
Thus, the answer is true.
