Answer:
73 g Mg(OH)₂
Explanation:
To find the mass of magnesium hydroxide, you need to (1) convert formula units to moles (via Avogadro's number) and then (2) convert moles to grams (via molar mass). Remember to arrange the conversions/ratios in a way that allows for the cancellation of units. The desired unit should be in the numerator. The final answer should have 2 significant figures because the given value (7.5 x 10²³) has 2 sig figs.
Avogadro's number:
6.02 x 10²³ formula units = 1 mole
Molar Mass (Mg(OH)₂):
58.32 g/mol
7.5 x 10²³ units Mg(OH)₂ 1 mole 58.32 g
----------------------------------- x ---------------------------- x -------------------- =
6.02 x 10²³ units 1 mole
= 73 g Mg(OH)₂
Answer : 4.8 florins can you exchange for your 4 guilders.
Solution : Given,
The current exchange rate for every 2.4 florins is 2.0 guilders
As per question,
The exchange rate is 2.0 guilders for every 2.4 florins
The exchange rate is 1 guilders for every 
florins
The exchange rate is 4 guilders for every 
florins
Therefore, the 4.8 florins can you exchange for your 4 guilders.
The liquid disilicon hexachloride reacts with water to form solid silicon dioxide, hydrogen chloride gas and hydrogen gas are
When liquid disilicon hexachloride reacts with water to form solid silicon dioxide , hydrogen chloride gas and hydrogen gas , the following chemical equation is:
now , we have to balance the eqaution,
Reactants product
Si 2 1
Cl 6 1
H 2 3

Explanation:
The equation of the reaction is given as;
6CO2 + 6H2O → C6H12O6 + 6O2
How many molecules of CO2 are present?
6 moles
How many atoms of oxygen are present in the reactants?
(6 * 2) + (6 * 1 ) = 12 + 6 = 18
How many atoms of carbon are present in the products?
(6 * 1 ) = 6
How many total atoms are present in C6H12O6?
6 + 12 + 6 = 24 atoms
Is the equation above balanced or unbalanced?
This is a balanced equation since the number of atoms of the elements is the same in the reactant and products.
