The reaction is:
2 KClO3(s) → 3 O2(g) + 2 KCl(s) <span>
<span>A catalyst simply lowers the activation energy so MnO2 is not
part of the overall reaction.
By stoichiometry:
<span>3.45 g KClO3 x 1 mol/ 122.55g KClO3 x 3 mol O2/ 2 mol KClO3 x
31.99g/ 1 mol O2 = 331.096/ 245.1 = 1.35 grams O2 produced
Answer:1.35 grams O2</span></span></span>
Answer:
C. 10.540 moles
Explanation:
divide grams by molar mass to get moles
Answer:
C. By being honest in recording the results of their own experiments
Explanation:
Honesty in recording results is ethical behaviour and the basis of scientific research.
A. is wrong. If you repeat the same experiment, you should always get the same result.
B. is wrong. Copying someone else's results is cheating and certainly unethical behaviour.
D. is wrong. Making up data is dishonest and unethical behaviour.
E. is wrong. Following your own instincts about safety procedures is unethical because your instincts may be wrong. following them may result in injury to yourself or to others.
1 mm ---------- 0.1 cm
38.2 mm ------ ?
38.2 x 0.1 / 1
= 3.82 cm
Answer: enzymes.
Explanation:
Microbial products are products derived from microorganisms. They may be primary or secondary metabolites. They are known to be environment friendly since they have biological origin. They are often degraded by enzymes which are also biological molecules. Degradation of materials using enzymes typically generates nontoxic products.
