Answer:
The temperature change is 80°C
Explanation:
Heat absorbed by the melting ice (Q) = mL = 312×336 = 104,832 J
∆T = Q/mC = 104,832/312×4.2 = 80°C
Answer:
Lithium
Explanation:
Alkali metals are group of metals which are present in first group of periodic table. As we know atomic number is equal to number of protons contained by a particular element. Therefore, the alkali metals along with there number of protons are listed below;
Alkali Metal Number of Protons
Lithium 3
Sodium 11
Potassium 19
Rubidium 37
Cesium 55
Francium 87
Hence, it is cleared from above table that Lithium is having fewer protons than 10.
