Answer:
To separate an insoluble solid from a soluble solid: Mixing the mixture with water, filtering out the insoluble solid, and then evaporating the water to isolate the soluble solid.

Answer:
i dont understand anything you typed sorry
Explanation:
2 C₁₇H₁₉NO₃ + H₂SO₄ → Product
Moles of H₂SO₄ = M x V(liters) = 0.0116 x 8.91/1000 = 1.033 x 10⁻⁴ mole
moles of morphine = 2 x moles of H₂SO₄ = 2.066 x 10⁻⁴
Mass of morphine = moles x molar mass of morphine = 2.066 x 10⁻⁴ x 285.34
= 0.059 g
percent morphine =
=
= 8.6 %
Answer:
H2SO4 + 2NaOH → Na2SO4 + 2H2O
Explanation:
This question is describing the neutralization reaction between dilute sulfuric acid (H2SO4) and sodium hydroxide (NaOH). These two compounds combine to form sodium salt and water as products (see the chemical equation below).
H2SO4 + NaOH → Na2SO4 + H2O
However, this equation is not BALANCED because the number of atoms of each element are not the same on both sides of the equation. To balance the equation, COEFFICIENTS are used as follows:
H2SO4 + 2NaOH → Na2SO4 + 2H2O
From this equation, the atoms of hydrogen (H), sulphur (S), oxygen (O), sodium (Na) are now equal on both sides, hence, it is said to be BALANCED.
<h3>
Answer:</h3>
The law of conservation of mass has already been applied. There is an equal number of each element on both sides of the equation.
<h3>
Explanation:</h3>
<u>We are given;</u>
C₂H₄ + 3O₂ → 2H₂O + 2CO₂
We need to ask ourselves the following questions;
Is the equation balanced?
- Yes, the equation because the number of atoms of each element is equal on both sides of the equation.
- That is; Reactants: 2 carbon atoms, 4 hydrogen atoms and 6 oxygen atoms.
- Products: 2 carbon atoms, 4 hydrogen atoms and 6 oxygen
What is the law of conservation of mass?
- According to the law of conservation of mass, the mass of reactants should always be equal to the mass of the products in chemical reactions.
What makes the equation obey the law of conservation of mass?
- For an equation to obey the law of conservation of mass, it must be balanced.
- In this case, <u>the equation given is already balanced and therefore obeys the law of conservation of mass</u>.
