When sodium hydroxide and sulfuric acid react, sodium sulfate and water are produced. Here is the balanced reaction: 2NaOH + H2SO4 → NaSO4 + 2H2O
If two moles of sodium hydroxide (the limiting reactant) are used, one mole of NaSO4 should be produced. How many grams of NaSO4 should be produced?

Asystem containing an ideal gas at a constant pressure of 1.22×10^5 pa gains 2140 j of heat. during the process, the internal energy of the system increases by 2320 j. what is the change in volume of the gas?

Give your knowledge of these things in your paper, you will compare and contrast analog and digital signals to determine which is more reliable for encoding and transmitting information. you’ll compare these features: signal shape numerical values for signal measurements amount of data that can be transmitted energy requirements privacy and security (ability of the signal to be encoded in a secret code) clarity of signal in the space provided, write down what you already know about any of these features. if you’re not sure, write down questions you might have about the features.
