I think the best answer is B. Even this is the broadest case for the Conservation of matter and the one for Energy, the only way this can be applied is in nuclear rxns.
Answer:
yes it is dangerous
Explanation:
Water reactive substances are dangerous when wet because they undergo a chemical reaction with water.
It’s D . It is a universal constant for all glasses
Answer:
0.70 M
Explanation:
- Molarity is the concentration of a given solution in moles per liter.
- Molarity is given in moles per liter of solution.
- It is calculated by dividing the moles of solute by the volume of solution.
In this case;
We are given;
Number of moles of HCl = 3.5 Moles
Volume of solvent, H₂O is 5.0 L
But, 
Therefore;

= 0.70 M
Thus, the molarity of the solution is 0.70 M or 0.70 moles/liter
