Answer:
Chemotherapy drugs are powerful medications that attack rapidly growing cancer cells. Unfortunately, these drugs also attack other rapidly growing cells in your body — including those in your hair roots. Chemotherapy may cause hair loss all over your body — not just on your scalp.
Answer:
1) Reaction rate= 0.001230 M/s
2) Reaction rate= 0.001052 M/s
3) Reaction rate=0.000855 M/s
Explanation:
Average Rate of the reaction is defined as rate at any instant of time is the rate of change in concentration of any one of the reactants or products with respect to particular time.It is given as;
: concentration at time respectively.
1) Interval: 0 s to 195 s
2) Interval: 195 s to 556 s
3) Interval: 556 s to 825 s
2. HF(aq) + K^(+)(aq) +OH^(-)(aq) → K^(+)(aq) + F^(-)(aq) + H_2O(ℓ)
<em>Step 1</em>. Write the <em>molecular equation
</em>
HF(aq) + KOH(aq) → KF(aq) + H_2O(ℓ)
<em>Step 2</em>. Write the <em>total ionic equation
</em>
HF and H_2O are <em>weak electrolytes</em>, so we write them as <em>molecules</em>.
HF(aq) + K^(+)(aq) +OH^(-)(aq) → K^(+)(aq) + F^(-)(aq) + H_2O(ℓ)
