Answer:
A chemical change occurred, a gas and precipitate was produced
Explanation:
From the question , we are informed of science lab, where Cash mixes two clear liquids together in a beaker. Bubbles are produced, and a white solid forms and settles to the bottom.
In this case the change that took place is chemical change ( is one where new product are formed after two substance react) the bubbles that is produced signify the presence of gas in the product, white solid formed is reffered to as a precipitate( which is reffered to as solid that is been formed from a particular solution).
Pressure is created by the number of collisions that occur between the molecules and the surface of container. If the temperature in the container is increased this will cause the molecules to move faster. ... By increasing the number of collisions, this will increase the pressure in the container.
Ex: A 5% increase in absolute temperature will resultin a 5% increase in the absolute pressure. ... Resultant pressure changes will vary. A useful thumb rule for water is that pressure in a water-solid system will increase about 100 psi for every 1 F increase in temperature.
This is called as such because the proton or H+ has taken on both lone electron pairs on the oxygen in the water molecule. As such it is s coordinate covalent bond.
