Answer: 12.011g/mol
Explanation: The molar mass of any element is usually stated at the bottom of periodic table (depending of your table anyways). Remember that the periodic table speaks to you in moles so every molar mass under the element is for 1 mole. By this I mean for example, 1 mole of Carbon = 12.011g of Carbon.
Answer:
32/21
Explanation:
Find the GCD (or HCF) of numerator and denominator. GCD of 32 and 21 is 1.
32 ÷ 121 ÷ 1.
Reduced fraction: 3221. Therefore, 32/21 simplified to lowest terms is 32/21.
Answer:

Explanation:
Hello,
In this case, for us to compute the absorbed heat, we apply the following equation:

Whereas we use the mass, specific heat and temperature change for the piece of aluminium, thus, we obtain:

It is positive as the heat is entering, therefore the temperature raises.
Best regards.
The answer is homogenous i think
