Answer:
1)2kclo3=2kcl+3o2
2)2NaCl+F2=2NaF+cl2
3)Pb(OH)2+2HCl=2H2O+PbCl2
4)2Albr3+3k2so4=6kbr+al2(so4)3
5)CH4+2O2=CO2+2H2O
Answer:
B. Soap solution
Explanation:
Hardness of water refers to the degree of calcium and magnesium in the water. In other words, hard water contains excessive mineral contents. The degree of hardness of a water body can be measured using the SOAP TEST KIT.
Due to the formation of insoluble minerals, soap forms an exvessive substance in the presence of hardwater because the particles or minerals contained in the water is reacting to form something insoluble. Hence, a SOAP test kit can be used to test the hardness of water.
Answer:
To isolate the microorganism from the mice and determine if it is identical to the original unknown bacteria.
Explanation:
The next step to take is to isolate the microorganism from the mice and determine if it is identical to the original unknown bacteria.
Koch's postulates opines four criterion for which a microbe will be regarded as a causative agent of a disease if the following takes place.
That, the microorganism should be present in all the organism suffering from the disease. That these isolated microorganism are meant to be grown in a pure culture. After being grown in the culture, they should be reintroduced in the susceptible but healthy host. In conclusion, from the experimental host, the microorganism must be re-isolated. Hence, cultured to see whether it is identical to the original specific microorganism.
The net ionic equation shown is for the reaction of an aqueous mixture of sodium hydroxide and hydrochloric acid.
<h3>What is net ionic equation of a reaction?</h3>
A net ionic equation is an equation of a reaction which only depicts the ions which react to form a product.
In a net ionic equation, the spectator ions are removed.
The net ionic equation shows a reaction between hydrogen ions and hydroxide ions to form water.
Therefore, the net ionic equation shown is for the reaction of an aqueous mixture of sodium hydroxide and hydrochloric acid.
