Answer:
A
Explanation:
water molecules are combined to make food
Answer:
b. contributes to binding of O2 by hemoglobin in lungs and release of O2 from hemoglobin in tissues.
Explanation:
- The Bohr effect is a phenomenon described by Christian Bohr. Is an affinity that binds oxygen and hemoglobin and is inversely related to the concentration of carbon dioxide. As CO2 reacts with water and an increase in CO2 results in a decrease in blood ph.
Answer:
c) 0.10M NaCl
Explanation:
<em>Options are:</em>
<em>a) 0.20M NaCl</em>
<em>b) Very acidic</em>
<em>c) 0.10M NaCl</em>
<em>d) 0.10M HCl + 0.20M NaOH</em>
<em>e) Slightly acidic.</em>
<em />
Based on the reaction:
NaOH + HCl → H₂O + NaCl
You can see than 1 mole of NaOH reacts per mole of HCl producing 1 mole of NaCl
Assuming 1L of 0.20M HCl reacts with 1L of NaOH, moles of both compounds are:
1L * 0.20mol/L = 0.20 moles reacts. That means moles of NaCl produced are 0.20moles in 2L. Molarity of NaCl is:
0.20mol / 2L = 0.10M NaCl
That means, right option is:
<h3>c) 0.10M NaCl</h3>
Answer:
Both alcohols are flammable, and both are used as disinfectants. There are varying grades of both in terms of purity, ethanol is more widely used in wet laboratories whereas isopropyl alcohol is preferentially used to disinfect electronic devices.
