0.357mol Au * (196.96g/1 mol)= 70.1g
You must use dimensional analysis to solve this problem by using the molar mass of Au (gold) to find out how much mass would be in only .357mol Au
Answer:
D. Different functional groups and different physical and chemical properties
Explanation:
A functional group is an atom or group of atoms within a molecule that determines the chemical and physical properties of the compounds it appears in.
The functional group of an alcohol is the -OH group while that of an ether is an oxygen atom bonded to two alkyl or aryl groups, R-O-R'.
Based on the above;
Option A is wrong because they have different functional groups, hence different properties
Option B is wrong because they don't have same functional group even though their properties are different
Option C is wrong because they have different properties even though they have different functional groups
Option D is correct because they have different functional groups and different properties.
Answer:
Anything that can be done to increase the frequency of those collisions and/or to give those collisions more energy will increase the rate of dissolving.
Explanation:
depended on the temperature
Answer:
1. aa
2. They have similar DNA
Explanation:
1. According to the question 1, wrinkled seeds (A) are dominant over round seeds (a) in pea plants. This means that, based on the law of dominance proposed by Mendel, wrinkled seeds will be expressed over round seeds in a heterozygous state (Aa).
However, since the round seed phenotype is a recessive trait, it will only be expressed when the alleles for round seeds (a) are the same in the gene i.e. aa genotype.
2. Based on the information in question 2, Ricky, who is working on a family tree for his school project, realizes that his close relatives all look similar in the pictures he collected. This is possible because of the SIMILARITY OF THEIR DNA (genetic material). Note that, relatives are connected by the genes that are inherited from one another, hence, they possess a similar DNA, which is the most valid reason for the resemblance.
