A)
K has a positive charge of 1
I has a negative charge of 1
S has a negative charge of 2
Pb has a positive charge of 2
2KI + PbS —> PbI2 + K2S
Explanation:
oxygen and are negatively charged anions because the oxygen atoms attract electrons. Ammonium is one of the few positively charged polyatomic ions or cations and doesn't contain oxygen.
Answer:
it is because of the bacteria and different things that go into waters such as ponds, rivers, lakes, seas, oceans, streams, and other body of waters and I should also add the chemicals that go into them as well
Explanation:
Options:
conduct an experiment
form a hypothesis
draw a conclusion
state the cause
Answer:
'<u>State the cause'</u> is not part of the scientific method.
Explanation:
The scientific method has three wholistic steps:
- Test the hypothesis
- Make observations from the experiment to the hypothesis
- Draw a conclusion or prediction from the experimental results.
A cause is neither a scientific term nor is it part of the processes of experimentation.
I hope this was helpful.
Answer:
The most state has the high volume is the gas state.
So here the answer is vaporization!!!!
Explanation:
The most state has the high volume is the gas state.
So here the answer is between vaporization and sublimation???
and when the sublimation is: the change of the material from the solid state to the gas state directly without pass to liquid state from the solid first then to the gas
and the vaporization is : The change of the material from the liquid state to the gas state by heating Ex: water vaporize at 100°
here, the answer is sublimation because the difference of volume which resulted from this process is more than the volume resulted from vaporization.
Plz mark brainlist!!
