98. A solution of 0.075 M CoBr$_2$ is saturated with H$_2$S ([H$_2$S] = 0.10 M). What is the minimum pH at which CoS begins to precipitate? CoS(s) $\rightleftharpoons$ Co$^{2+}$(aq) + S$^{2-}$(aq) $K_{sp}$ = 2.3 × 10$^{-27}$ H$_2$S(aq) + 2H$_2$O(l) $\rightleftharpoons$ 2H$_3$O$^{+}$(aq) + S$^{2-}$(aq) K = 8.9 × 10$^{-27}$

What genotypes and in what frequencies would you expect in future offspring from these two parents? 2. Phenylketouria(PKU) is an inherited disease caused by a recessive allele. If a woman and her husband, who are both carriers, have three children, what is the probability of each of the following? i. All three children are of normal phenotype. ii. All three children have the disease. 3. The genotype of F1 individuals in a tetrahybrid cross is AaBbCcDd. Assuming independent assortment of these four genes, what are the probabilities that F2 offspring will have the following genotypes? i. aabbccdd ii. AaBbCcDd iii. AABBCCDD iv. AaBBccDd v. AaBBCCdd 4. What is the probability that each of the following pairs of parents will produce the indicated offspring?(assume independent assortment of all gene pairs) i. AABBCC X aabbcc ---à AaBbCc ii.

In maize plants, a dominant allele I inhibits kernel color, while the recessive allele i permits color when homozygous. At a different locus, the dominant allele P causes purple kernel color, while the homozygous recessive genotype pp causes red kernels. If plants heterozygous at both loci are crossed, what will be the phenotypic ratio of the offspring?

The average length of a 4-year-old fish is 27 inches, and that of a 19-year-old fish is 54.9 inches. A fish's age and average length are approximately linearly related. Let L be the average length (in inches) of the fish at age a years. Find an equation of a linear model to describe the data. Discuss each part of (a)-(c) (a) What does it mean that \"A fish's age and average length are approximately linearly related.\" (b) \"The equation of linear model to describe the data\" is a linear equation - namely, equation of a line. Explain how you find the slope of the line, and what is the meaning of the slope. (c) What is the equation of linear model? (d) From your linear model, what is the average length of the fish at birth? Do you think this answer is reasonable?

Use FIFO to calculate CGM, ASE, and Ending WIP for February. 2. Christineco makes waffles. Spoilage is detected only when waffles are complete. Beginning WIP is 78% complete with respect to materials and 34% complete with respect to conversion. Ending WIP is 58% complete with respect to materials and 27% complete with respect to conversion. Normal spoilage is 40 waffles. Of the completed units, 52 were spoiled. Units Beg WIP Started Completed 800 3200 3550 Costs DM Beg WIP $880 Feb Costs $2,500 Conversion $5,600 $22,450 Using FIFO, create the journal entries for CGM and Abnormal Spoilage Expense. Are costs increasing or decreasing?
