When the equation Si(s) + HF(aq) → SiF4(g) + H2(g) is balanced, what is the coefficient for HF?

When the following equation is balanced using the smallest possible integers, what is the number in front of the substance in bold type?KClO3 → KCl + KClO4

In Dexter and Kerry cattle, animals may be polled (hornless) or horned. When many offspring were obtained from matings between polled Kerrys and horned Dexters, one-half were found to be polled Dexters and one-half polled Kerrys. When these two types of F1 cattle were bred with one another, the following F2 data were obtained: 3/8 polled Dexters, 3/8 polled Kerrys, 1/8 normal Dexters, 1/8 normal Kerrys. A geneticist was puzzled by these data and interviewed farmers who had bred these cattle for decades. She learned that Kerrys were true-breeding. Dexters, on the other hand, were not true-breeding and never produced as many offspring as Kerrys. Using symbols explain the inheritance of the traits and explain why Dexters are not true breeding.

The two general types of reactions in photosynthesis are 1. ___________________________________, and  2. ______________________________________________.

When the following equation is balanced using the smallest possible integers, what is the coefficent of oxygen gas?C5H12(g) + O2(g) → CO2(g) + H2O(g)

When the following equation is balanced using the smallest possible integers, what is the number in front of the substance in bold type?MnO2 + HCl → MnCl2 + Cl2 + H2O

When the following equation is balanced using the smallest possible integers, what is the number in front of the substance in bold type?PCl5 + H2O → H3PO4 + HCl

When the following equation is balanced using the smallest possible integers, what will be the coefficient for the substance that has been emboldened?NBr3 + NaOH → N2 + NaBr + HOBr

A heterozygous tall pea plant self fertilizes and produces 9 tall plants and 7 dwarf ones. The dwarf phenotype is hypothesized to be present only in homozygous recessive individuals.  Calculate χ2 for this data and enter this value. Using the table above, estimate the probability.  

When the following equation is balanced using the smallest possible integers, what is the number in front of the substance in bold type?SiCl4 + H2O → SiO2 + HCl
