Answer:
Average speed of the motorist is 58 km/hour.
Explanation:
Total distance covered by motorist = D = 406 km
Total time taken motorist = T = 7 Hours
The formula of an average speed is given by:
Average speed of the motorist is:
B. Bias makes the results less reliable.
C. Bias makes the results easier to interpret.
D. Bias makes the results not publishable.
Answer:
B
Explanation:
Bias may make one side look worse than they actually are.
(1) H–Br (3) H–F(2) H–Cl (4) H–I
This is an example of negative mutation. Negative mutations produce a phenotype that acts antagonistically to the wild-type phenotype. On the other hand positive mutation produce a phenotype that acts synergistically to the wild-type phenotype.
The negative mutation will negatively affect the long term survival of the butterfly species as the mutation makes the new butterfly offsprings more visible to predators.
Answer: The correct answer is Option B.
Explanation: The compound given to us is . To write the IUPAC name for this compound, we need to follow some rules:
1. First write the name of the cation with its oxidation state in roman numbers.
2. Then write the name of the anion which may be a polyatomic ion or a non-metal.
3. The anion is used with a suffix '-ide'. Example: For chlorine, the anion would be named as chloride, for sulfur, the anion would be sulfide.
For the given compound, 2 silver atoms are needed to neutralize the charge on 1 sulfur atom.
Hence, the oxidation number of silver atom is '1'. So, the IUPAC name for the compound will be silver (I) sulfide.
Therefore, the correct option is B.
