Answer: to reach mineral ores on the surface of earth
Explanation:
Out of
the following given choices;
A. increasing
the pH of the salt.
B. increasing
the surface area of the salt.
C. increasing
the pressure of the salt.
<span>D. increasing
the temperature of the salt.</span>
The answer is B. When a substance is reduced to smaller
sizes, its surface area to volume ratio increases. Therefore crushing barium
salts to smaller particles increase the surface area on which it reacts with
the acid. This consequently increases the rate of speed of the reaction.
Answer:
2NaCl > Cl2 + 2Na
Explanation:
2 moles of sodium chloride is irreversible to chlorine gas plus 2 moles of solid sodium
The density of the patient's hemoglobin in their blood in units of g/ml = 0.2g/mL
<h3>Calculation of hemoglobin density</h3>
Hemoglobin is the red blood cell pigment that transports oxygen to the body cells.
1 gram of hemoglobin = 2.15mg
Blood volume of the patient is = 4.9ml
Density= mass/volume
Therefore the density of patients hemoglobin= 1/4.9 = 0.2g/mL
