Carl adds a 6.70-gram cube of ice at 0.0°C to cool a glass of juice, As the ice melts, the temperature of the newly melted water

rises to 25.4°C. Water’s heat of fusion is 334 joules/gram, and its specific heat is 4.186 joules/gram degree Celsius. How many joules of energy did the ice cube gain?

Answer:

2,950

joules.

Explanation:

The units don’t need conversion, and the formula doesn’t need changing.

First, determine the energy required to melt the ice:

Q = mHf

Q = 6.70 g × 334

Q = 2,240 J

Next, determine the energy needed to raise the temperature of the newly melted water:

Q = mCΔT

Q = 6.70 g × 4.186 × (25.4°C – 0.0°C)

Q = 712 J

Now, add the energy values. Express the answer to 3 significant figures:

2,240 J + 712 J = 2,950 J.

2. What group is Ballardium located? (Bu) *
elena-14-01-66 [18.8K]

Answer:

This question appears incomplete

Explanation:

There is no such element known as "Ballardium (Bu)" in the periodic table. However, there are elements with a bit of similarity in spellings and pronunciation such as Beryllium (Be) which is found in group 2 (meaning it is an alkali earth metal), Berkelium (Bk) which is an actinide (meaning it is radioactive) and Vanadium (V) which is found in group 5 of the periodic table (meaning it's a transition metal).

A gas with an empirical formula C2H2O has a molecular weight of 120.6g/mol. A possible molecular formula for the gas is
Virty [35]

M(C2H2O)= 12.0*2 +1.0*2 +16.0 = 42 g/mol is a molar mass for empirical formula.

120.6g/mol/42g/mol ≈ 3

So, empirical formula should be increased 3 times,

and molecular formula is C6H6O3.

Answer is D.
