Answer:
An oxidising agent oxidises something else. Oxidation is loss of electrons (OIL RIG). That means that an oxidising agent takes electrons from that other substance.
Explanation:
Given:
1 mole of compound synthesized from its elements
Temperature of the substances in their standard states = 25 degrees Celcius
First, gather data from reference books on the standard heats of formation of the elements. Then set up a balanced equation for the reaction. From there, calculate the heat of reaction.
There are 0.5 moles of NaCl present in a 29.22g sample.
to find moles of a compound you would look at the periodic table to find the mass. in this case, the mass of NaCl is 58.44 g/mol. now, you divide the sample mass of 29.22g by 58.44 g/mol. the grams will cancel each other out and you’re left with 0.5 mol in that sample
hope this helps!
Answer:
The correct answer is :'The gravitational force between two objects is related mathematically to their mass and the distance between them'.
Explanation:
A scientific law is a statement which explains physical phenomena and has been tested multiple times through the correct scientific methods and experimentation. It will give same results and observations after each conduct.
A scientific law comes into picture after the acceptance of a theory which explains or exposes the reason behind any physical phenomena occurrence.
So the best example of scientific law:
The gravitational force between two objects is related mathematically to their mass and the distance between them.
