For the reaction 2 HCl + Na2CO3 → 2 NaCl + H2O + CO2 8.0 moles of CO2 is collected at STP. What is the volume of CO2? 1) 57.6 L 2) 22.4 L 3) 0.0250 L 4) 2.80 L 5) 179 L 6) 0.357 L

Mrs. smith ordered a root beer float (vanilla ice cream + root beer). mrs. smith noticed that the three states of matter (solid, liquid, and gas) all existed simultaneously in her root beer float. a. identify each phase of matter in the root beer float. b. describe the particles of all three phases of matter in the root beer float. (how are the particles arranged and moving? ) c. identify one phase change you would see in a root beer float and described what causes this change.

How can you use chemical equations to predict the products of the reaction you can carry out?

Avariable that is not being directly tested during an experiment should be changed varied experimented controlled
