Scientists are planning an investigation to collect evidence to help predict future magnetic pole reversals of Earth’s magnetic field. Using the information in Figure 3, describe how scientists can collect data on changes in Earth’s magnetic poles and explain how this data can be used to predict future magnetic pole reversals

In a laboratory experiment, a fermenting aqueous solution of glucose and yeast produces carbon dioxide gas and ethanol. the solution was heated by burning natural gas in a bunsen burner to distill the ethanol that formed in the flask. during the distillation, the ethanol evaporated and then condensed in the receiving flask. the flame of the burner was kept too close to the bottom of the flask and some of the glucose decomposed into a black carbon deposit on the inside of the flask. during this experiment the following changes occurred. which of these changes involved a physical change and not a chemical change? check all that apply. 1-condensation of ethanol 2-evaporation of ethanol 3- formation of carbon dioxide gas from glucose burning of natural gas 4-formation of ethanol from glucose by yeast 5-formation of a carbon deposit inside the flask

In a reaction (at equilibrium) that makes more moles of gas than it consumes, what is the effect of increasing the pressure?

Match the mixture with the substance// i really need on this guys (it’s a pic btw)
