Hey I need help with some chemistry homework! 1. 12700 J/

(116 g) (4.8°C)

2. (75kg) (5.0m)/ (2.5s) (6.0s)

3. (12kg) (30m)/ (10s)

What does x represent in the formula for the compound xcl4?

Select the correct answer. when carbon dioxide dissolves in water, it sometimes reacts with water to form carbonic acid as in this balanced equation: co2 + h2o → h2co3. if 495 milliliters of carbon dioxide at 25°c and 101.3 kilopascals reacts with excess water, what is the theoretical yield of carbonic acid? use the periodic table and the ideal gas resource a. 0.889 g b. 1.10g c. 1.27g d. 2.02g what's the answer! quick!

Does the number of ions in solution increase, decrease, or remain constant? it continuously decreases. it continuously increases. it decreases at first, then increases. it increases at first, then decreases.
