A class was performing an experiment to discover the pH values of some common household substances. The results of three groups are shown in the table below. Substance Group 1 pH Group 2 pH Group 3 pH Lemon juice 2.2 2.2 2.1 Vinegar 2.8 2.8 8.2 Baking soda 8.4 8.5 8.4 Milk of magnesia 10.2 10.3 10.2 Which statement best describes evidence that Group 3’s data are less valid than the data for the other two groups? Group 3’s pH value for lemon juice is lower than the values of the other two groups. Group 3’s pH value for vinegar is much higher than the values of the other two groups. Group 3’s pH value for baking soda does not exactly match the values of the other two groups. Group 3’s pH value for milk of magnesia is different from the value obtained by Group 2.

This is s cute awee : (( . well if she's showing you signs that she may like you , then shoot your shot ! don't be afraid . & if you're unsure that she's giving you these signs , then wait out for a little bit . most girls are different . some may act really sweet , but only bc you're a good friend of hers . that , or she might like you . you just never know . but i think you should sit down with her & tell her how you feel . but don't be awkward & shy . just be straight up & tell her how you feel . if the feelings aren't mutual , then don't cry about it . you need to respect her decision & look for others in the world . feelings can be difficult & confusing , but don't be afraid to show them . i say you play it out & if you're still unsure about it , talk to her . - rach
