Bacillus: rod shaped
Spiral: curve, spiral, or twisted
Ans2) Bacteria are classified into five groups according to their basic shapes:
spherical (cocci),
rod (bacilli),
spiral (spirilla),
comma (vibrios) or corkscrew
(spirochaetes)
Answer:
Concept: Advanced Chemistry Techniques
- Use the periodic table to locate the nearest noble gas (At the far right)
- P is #15 and the nearest noble gas is #10 NE
5 x 2 = 10
3 x 3 = 9
10/9, or 1 1/9 is your answer
hope this helps
Answer:
B. , C. and D.
Explanation:
pH is defined as the negative logarithm of the concentration of hydrogen ions.
Thus,
pH = - log [H⁺]
pH scale generally runs from 1 to 14 where pH = 7 represents neutral medium, pH < 7 represents acidic medium and pH > 7 represents basic medium.
Also, pH + pOH = 14
(a) So, pOH = 11.21
pH = 14 - 11.21 = 2.79
The solution is acidic.
(b) pH = 9.42
The solution is basic.
c. [OH⁻] > [H⁺]
More concentration of hydroxide ions leads to basic solution.
d. [OH⁻]> 1.0 x 10⁻⁷ M
1.0 x 10⁻⁷ M leads to neutral solution and hydroxide ions concentration greater than this yields to basic solution.
