I’m assuming you mean 5g of magnesium :)
Answer:
Metamorphic rock
Explanation:
metamorphic rocks do not get hot enough to melt they just get denser if they did they would become igneous rocks.
Answer:62.66°C or 235.66K
Explanation:Q=McpT, the energy was given in calories so you first convert to Joules by multiplying the value in calories by 4.184J.
17*4.184=71.128kJ.
71.128kJ=mcpT
71.128kJ=245*4.187*(T-Tm)
Tm is the final temperature of the mixture. The T is the temperature given which should be converted to Kelvin by adding 273...T=32+273=305K.
71128J=245*4.187*(305-Tm)
71128=312873.575-1025.815Tm
1025.815Tm=312873.575-71128
1025.815Tm=241745.58
Tm=241745.58/1025.815
Tm=235.66K
3.07g H2
27.4/26.98/2x3x1.01x2=3.07
