Answer:
Zinc is Zn and Magnesium is Mg
Answer: The pressure after the tire is heated to 17.3°C is 167 kPa
Explanation:
To calculate the final temperature of the system, we use the equation given by Gay-Lussac Law. This law states that pressure of the gas is directly proportional to the temperature of the gas at constant pressure.
Mathematically,
where,
are the initial pressure and temperature of the gas.
are the final pressure and temperature of the gas.
We are given:
Putting values in above equation, we get:
Hence, the pressure after the tire is heated to 17.3°C is 167 kPa

2. co2 and h20 was the product of the reaction
3. cu is replaced with co
4. 2 compounds become one compound
5. ca is replaced with na and na is replaced with ca
<span> some unique properties about ice that differ from liquid water to water vapor are that it is a solid, not a liquid or gas. It also expands. </span>
Answer:In astronomy, geography, and related sciences and contexts, a direction or plane passing by a given point is said to be vertical if it contains the local gravity direction at that point. [1] Conversely, a direction or plane is said to be horizontal if it is perpendicular to the vertical direction. In general, something that is vertical can be drawn from up to down (or down to up), such as the y-axis in the Cartesian coordinate system.

Historical definition
Girard Desargues defined the vertical to be perpendicular to the horizon in his 1636 book Perspective.
The word horizontal is derived from horizon,[2] whereas vertical originates in the late Latin verticalis, which is from the same root as vertex, meaning "highest point".[3]
