Answer: He ruptured his Achilles tendon
Explanation:
A compound is composed of 2 or more different elements and or atoms, and thus 1. CS2 would be a compound for the above reason.
Answer:
Explanation:
= Mass of metal = 19 g
= Specific heat of the metal
= Temperature difference of the metal =
V = Volume of water = 150 mL =
= Density of water =
= Specific heat of the water = 4.186 J/g°C
= Temperature difference of the water =
Mass of water
Heat lost will be equal to the heat gained so we get
The specific heat of the metal is .
We are given with the ionic equation
<span>Li+(aq) + OH−(aq) + H+(aq) + Cl−(aq) → Li+(aq) + Cl−(aq) + H2O(l)
First, let us make sure that the equation is balanced. By inspection, the species on the left is balanced with the species on the right.
Next, we must identify any spectator ions. These are ions which are present in both the reactant and product side. The spectator ions are
Li+ (aq)</span>
Cl−(aq)
Cancel out the spectator ions resulting in the net ionic equation.
OH−(aq) + H+(aq) → H2O(l) <span />
