An experiment is designed to determine if the amount of sugar in a drink affects the likelihood that bees will be attracted to it. sample a is 100 ml of pure water. sample b is 100 ml of water with 1 gram of sugar dissolved in it. sample c is 100 ml of water with 2 grams of sugar dissolved in it. all samples are placed on a picnic table. one observer is assigned to each drink. the observers count the number of bees that visit the drink during a 15-minute interval. in the above experiment, which factor is the independent variable? the number of bees that visit the amount of sugar in the sample the temperature of the sample the color of the sample

Consider three unlabeled bottles, each contain small pieces of one of the following metals. - magnesium - sodium - silver the following reagents are used for identifying the metals. - pure water - a solution of 1.0 molar hcl - a solution of concentrated hno3 (a) which metal can be easily identified because it is much softer than the other two? describe a chemical test that distinguishes this metal from the other two, using only one of the reagents above. write a balanced chemical equation for the reaction that occurs. (b) one of the other two metals reacts readily with the hcl solution. identify the metal and write the balanced chemical equation for the reaction that occurs when this metal is added to the hcl solution. use the table of standard reduction potentials (attached) to account for the fact that this metal reacts with hcl while the other does not. (c) the one remaining metal reacts with the concentrated hno3 solution. write a balanced chemical equation for the reaction that occurs. (d) the solution obtained in (c) is diluted and a few drops of 1 m hcl is added. describe what would be observed. write a balanced chemical equation for the reaction that occurs.
