Answer:
2HNO3 + Ca(OH)2 ===> Ca(NO3)2 + 2H2O
Explanation:
This a neutralisation reaction. The first thing to note is that this type of reaction forms salt and water.
Note that the formula of water is H2O. So write this at the right hand side.
==> H2O
Next note that the salt should contain the acid radical (NO3) and the metallic part of the base (Ca) written well following the rule for writing chemical equation; thus
==> Ca(NO3)2 + H2O
The next step is to write the reactants at the right hand side of the equation;
HNO3 + Ca(OH)2 ==> Ca(NO3)2 + H2O
The final step is to count the number of atoms in each side of the equation to make sure they are equal and balanced.
In the above equation, H atoms are three at the left hand side add 2 to to H- containig compound on both side as to balance up. Thus
2HNO3 + Ca(OH)2 ===> Ca(NO3)2 + 2H2O
The equation 2HNO3 + Ca(OH)2 ===> Ca(NO3)2 + 2H2O is balance.
Answer:
Smog can be classified as two types. They are
Oxidizing smog
Reducing smog
Oxidizing smog:
The smog which has the property of high concentration of oxidizing agents is known as oxidizing smog. Oxidizing smog can also known as photochemical smog.
Example: Ozone.
Reducing smog:
The smog which has high concentration of sulfur Dioxide is known as reducing smog.Photochemical smog which is very dangerous is called oxidizing smog because it consists of the oxidizing agent ozone.......the other one is reducing smog which consists of reducing agent sulphurdioxide.
2.6 M hBr
This would be the correct answer.
Their lungs would try to expand to about 4 timed the normal volume which would force air into the various body tissues. this can cause a lung expansion injury and it could case air embolism. Air embolism is when air bubbles get trapped in blood vessels. This can lead to a blockage which will could be fatal.
