Answer:3 atoms of Mg 6 atoms of O and 6 atoms of H
Explanation:
Answer:
Moles of
= 6 moles
Explanation:
The reaction of
and
to make
is:
⇒
The above reaction shows that 2 moles of Sc can react with 3 moles of
to form 
Mole Ratio= 2:3
For 10 moles of Sc we need:
Moles of
= 
Moles of
= 
Moles of
=15 moles
So 15 moles of
are required to react with 10 moles of
but we have 9 moles of
, it means
is limiting reactant.


Moles of ScCl_3= 6 moles
Answer:
True
Explanation:
Here is an example: chemical properties include flammability, toxicity, acidity, reactivity. we observe the changes of these properties. Therefore, It's true.
Answer:
Explanation — This page looks at the oxidation of alcohols using acidified sodium or ... of sodium or potassium dichromate(VI) acidified with dilute sulfuric acid. ... The electron-half-equation for this reaction is as follows: ... To do that, oxygen from an oxidizing agent is represented as [O]. ... Article type: Section or Page.
Gay-Lussac's law gives the relationship between pressure and temperature of a gas.
it states that for a fixed amount of gas of constant volume pressure is directly proportional to temperature.
P/T = k
where P - pressure, T - temperature and k - constant

where parameters for the first instance are on the left side and parameters for the second instance are on the right side of the equation.
temperature should be in the kelvin scale,
T1 = 22 °C + 273 = 295 K
substituting the values in the equation

T = 492 K
new temperature - 492 - 273 = 219 °C
