Answer:
721 J
Step-by-step explanation:
At the bottom of its swing, all the potential energy of the pendulum has been converted to kinetic energy.
KE = 721 J
The scale will read <u>112 grams.</u>
Why?
Since we already know the percent error of the scale (12%) and we also know the mass of the block that is placed on the scale, we can calculate what will be the read of the scale by using the following formula:
We can see that the scale will read 112 grams.
Let's verify that we are right by using the following formula to verify if the obtained value for the scale read will be 12%:
Hence, we can see that the scale will read <u>112 grams.</u>
Have a nice day!
Answer: Aqua fortis is also known as Nitric Acid
Explanation: and the process in making aqua fortis is THE OSTWALDS PROCESS
detailed explanation by me
ammonia is also used in this process, which is reacted with oxygen and water and a catalyst platinum.
HOPE THIS HELPSS!!!
the states of the reactants and products
the temperature and pressure at which the reaction was carried out
the relative amounts of reactants and products
the type of catalyst that is used to speed up the reaction
whether the reaction can go in both directions
Explanation:
A chemical equation is an equation that shows how the reactants are combining together to give the products.
The following are the information to include when writing a chemical equation;
- the states of the reactants and products
whether solid, liquid or gases or aqueous, It is usually appended as a subscript in bracket
- the temperature and pressure at which the reaction was carried out
this shows the condition under which the reaction was carried out. It also gives useful information that can be used to quantitatively determine heat changes in a reaction.
- the relative amounts of reactants and products
this is usually derived from the balanced equation. They are the numbers appended at the beginning of the species in the equation
- the type of catalyst that is used to speed up the reaction
it is a good practices to provide the information about the catalyst used.
- whether the reaction can go in both directions
→ signifies one direction
⇔ both directions

Answer:
The mass of one mole of a substance is equal to that substance's molecular weight. ... water is 18.015 atomic mass units (amu), so one mole of water weight 18.015 grams. ... Avogadro's number is a proportion that relates molar mass on an atomic ... one molecule of water (H2O), one mole of oxygen (6.022×1023 of O atoms)
