Answer:
because it is first before the small intestine and it digests food first
Explanation:
Answer:
CaCO₃(s) + 2 H⁺(aq) + 2 Cl⁻(aq) ⇒ Ca²⁺(aq) + 2 Cl⁻(aq) + H₂O(l) + CO₂(g)
Explanation:
Let's consider the molecular equation that occurs when CaCO₃(s) reacts with HCl(aq).
CaCO₃(s) + 2 HCl(aq) ⇒ CaCl₂(aq) + H₂O(l) + CO₂(g)
The complete ionic equation includes all the ions and the compounds that do not dissociate in water.
CaCO₃(s) + 2 H⁺(aq) + 2 Cl⁻(aq) ⇒ Ca²⁺(aq) + 2 Cl⁻(aq) + H₂O(l) + CO₂(g)
Answer:
4.15 M
Explanation:
In order to find the molarity of a stock solution of Z, we use the formula;
Co = 10pd/M
where;
p = percentage by mass of Z
d = density of Z
M= molar mass of Z
Substituting values;
Co= 10 * 35 * 1.4/118
C0= 4.15 M
Answer:
<h3>The answer is 82.86 cm³</h3>
Explanation:
The volume of a substance when given the density and mass can be found by using the formula
From the question
mass of wood = 44 g
density = 0.531 g/cm³
It's volume is
We have the final answer as
<h3>82.86 cm³</h3>
