<h3>
Answer:</h3>
- The complete ionic equation is;
H⁺(aq)CHO₂⁻(aq) + K⁺(aq) OH⁻(aq) → K⁺(aq) CHO₂⁻(aq) + H₂O(l)
H⁺(aq) + OH⁻(aq) → H₂O(l)
<h3>
Explanation:</h3>
- The balanced equation for the reaction between HCHO₂ and KOH is given by;
HCHO₂(aq) + KOH(aq) → KCHO₂(aq) + H₂O(l)
- Ionic equation involves writing a balanced equation showing all the ions in a chemical reaction.
- The complete ionic equation will therefore be;
H⁺(aq)CHO₂⁻(aq) + K⁺(aq) OH⁻(aq) → K⁺(aq) CHO₂⁻(aq) + H₂O(l)
- Net ionic equation on the other hand, shows only the ions that are directly involved in the reaction and omits the spectator ions.
- The net ionic equation will be;
H⁺(aq) + OH⁻(aq) → H₂O(l)
Answer:
90 °C
Explanation:
First, we must know the specific heat capacity of water, which is defined as the energy required to heat 1 gram of water by one degree Celsius. The specific heat capacity of water is 1 cal·g⁻¹°C⁻¹.
The equation we will use is Q = mcΔt, where Q is the heat energy, m is the mass, c is the specific heat capacity, and Δt is the temperature change. We will rearrange the equation to solve for Δt and substitute the values:
Δt = Q / (mc) = (90 kcal)(1000 cal/kcal) / (1 kg)(1000 g/kg)(1 cal·g⁻¹°C⁻¹) = 90 °C
For a first order reaction, the half life is inversely proportional to the rate constant.
The formula is
half life = ln(2)/k = 0.693/k
where k is the rate constant
t = 5.50 minutes
k = ln(2)/5.50 = 0.126 min^-1
Your rate constant is 0.126 min^-1.
The right answer for the question that is being asked and shown above is that: "<span>b. number/timed." Reaction Rate refers to the </span> speed of reaction<span> for a reactant or product in a particular </span>reaction<span> is intuitively defined as how fast or slow a</span>re action<span> takes place.</span>
