Answer:
The answer to your question is a balanced equation
Explanation:
Chemical formulas are extremely useful in chemistry and these formulas follow the law of proportions but not the law of conservation of matter.
Coefficients indicate that an equation is balanced if these numbers are in proportion but it is not the answer.
Balanced equation is a feature of the law of conservation of matter.
Subscripts are necessary for chemical reactions but they are not a feature of the law of conservation of matter.
Explanation:
a. CGS system: centimetre as the unit of length, the gram as the unit of mass, and the second as the unit of time
b. SI system: metre as the unit of length, the kilogram as the unit of mass, and the second as the unit of time
Answer: Mass
Explanation:
The moon and the Earth have a much higher gravitational pull than people because they weigh way more.
Answer:
Electromagnetic
Explanation: I hope this helps :D
Indicators are substances that produce colour changes to indicate the presence or absence of a threshold concentration of a particular chemical specie. In neutralization reaction, indicators produce colour changes on the basis of the pH of the solution. In acid base titration, indicators are used to indicate the end point of the neutralization reaction. The end point of acid base titration is the equivalence point when the moles of the of the standard solution is equal to the moles of the unknown solution. Thus, the correct option is B. Note that the solution that contain the H+ ions is the acid.
