Explanation:
Silver nitrate can react with various compounds to form different products. The weight of products may be different from the original solution introduced due to combustion reaction, as heat energy is released during the chemical process.
Answer:
D It must be equal to 1.00
Explanation:
The refraction in the second medium must be equal to 1. The refraction index is given as the ration of the angle of incidence to the angle of refraction. This is given as a fraction. In other words:

where Θ₁ and Θ₂ are angles of incidence an refraction, and n is the refractive index.
At a critical angle, the refraction is equal to the reflection inside the medium. This results in a phenomenon called total internal reflection where light is reflected internally in the medium.
Answer:
1. 315.4 K
2. 1560 °C
Explanation:
To convert from celsius to Kelvin, the following formula can be used:
T(K) = T(°C) + 273
Where:
T(K) => Temperature in Kelvin
T(°C) => Temperature in degree celsius
1. Determination of the temperature in Kelvin.
Temperature (T) in °C = 42.4 °C.
Temperature (T) in K =?
T(K) = T(°C) + 273
T(K) = 42.4 °C + 273
T(K) = 315.4 K
2. Determination of the temperature in degree Celsius.
Temperature (T) in K = 1833 K
Temperature (T) in °C =?
T(K) = T(°C) + 273
1833 = T(°C) + 273
Collect like terms
T(°C) = 1833 – 273
T(°C) = 1560 °C
