Explanation:
I think at HF is the answer because the pH value of weak acid are 4 and 5
please mark the brainliest if you are satisfied thank you very much
Answer: 1094 K
Explanation:
1560 mmHg/445 K= P2/312 k
Answer:
It released hydroxide ions (OH ¯).
Explanation:
A PH of 8.3 indicates that the solution has become a basic solution.
Now, for us to have a basic solution from the addition of an alka-seltzer to Koolaid, it means the Alka-seltzer released plenty of hydroxide ons (OH¯) to the solution.
Answer:
Lightbulb: electrical energy to light energy
Alarm Clock: electrical energy to sound energy
Rollercoaster: electrical energy to mechanical energy
Riding a Bike: chemical energy to mechanical energy
Explanation:
Light bulbs, alarm clocks, and roller coasters require electrical energy to work. This energy then changes into the subsequent types. Light bulbs primarily emit that energy in the form of light, alarm clocks change that energy into sound, and roller coasters begin to move (mechanical). People power bikes, and the energy in our body is stored as chemical energy. So, when we rides bikes, that energy gets turned into moving (mechanical) energy.
Answer:
A Chemical equation is balanced if the reactants side of the chemical reaction has the same number total of atoms of elements as the products side of the chemical equation. While a Chemical equation is unbalanced if the reactants side of the chemical reaction has a different number total of atoms of elements as the products side of the chemical equation
