Answer:
Hey mate, here is your answer. Hope it helps you.
Explanation:
To show how substances in a chemical reaction interact and to keep track of all elements and the number of atoms in each element on each side of the equation.The purpose of writing a balanced chemical equation is to know: the reactants (starting material) and products (end results) that occur. the ratios in which they react so you can calculate how much reactants you need and how much products can be formed.
Answer:
Two of the three salts are soluble.
One of the three salts is soluble.
Explanation:
<em>One or two of the three salts would be soluble in water depending on if the water is cold or hot.</em>
<u>According to the solubility rules of chloride salts, all chlorides are soluble in cold water except for those of silver (Ag), lead (Pb), and mercury (I) (Hg). </u>
This thus means that both AgCl and 
would be insoluble in cold water while LiCl would be soluble.
is, however soluble in hot water.
Hence, in cold water, one of the three salts (LiCl) would be soluble, while in hot water, two of the three salts (LiCl and ) would be soluble.
Mass of water required = 64.42 g
<h3>Further explanation</h3>
Given
Reaction
6CO2 + 6H2O → C6H12O6 + 6O2
157.35 g CO2
Required
mass of water
Solution
mol CO₂ = mass : MW CO₂
mol CO₂ = 157.35 g : 44.01 g/mol
mol CO₂ = 3.575
From the equation, mol ratio CO₂ : H₂O = 6 : 6, so mol H₂O = mol CO₂=3.575
Mass H₂O = mol x MW H₂O
mass H₂O = 3.575 x 18.02
mass H₂O = 64.42 g
Answer:
Material is less dense than water so it will float in water.
Explanation:
Given data:
Mass of material = 110 g
Volume of material = 312 cm³
Will it float or sink in water = ?
Solution:
First of all we will calculate the density of material.
d = m/v
d = 110 g/ 312 cm³
d = 0.35 g/cm³
The density of water is 1 g/cm³ it means material is less dense than water so it will float in water.
