Yes it is polar because if you drew it out, it would be a trigonal pyramidal. Since it has a lone pair, it would be polar.
Answer:
Balanced equations and mole ratios
In general, mole ratios can be used to convert between amounts of any two substances involved in a chemical reaction.
Explanation:
yw
Answer:
67.91 g of CuCl2; 32.09 g of Cu.
Explanation:
The two masses add to 100.0 g, the initial amount of starting material, demonstrating the law of conservation of matter.
Answer:
by statistical analyses, especially by determining the p-value
Explanation:
In general, observations and results obtained from experimental procedures are subjected to a statistical test to check the robustness of the working hypothesis. The p-value is the most widely used statistical index in order to test such observations and results. The p-value is the statistical probability of obtaining extreme observed results when the null hypothesis is considered correct. A p-value lesser than 0.05 generally is considered statistically significant and then the null hypothesis can be rejected. In consequence, a very low p-value (which is obtained by statistical analysis of the observations and results), indicates that there is strong evidence in support of the alternative hypothesis.
Answer: The answer is Fossil A is younger than the index fossil.
Explanation: Because it’s the newest layer
