12500 J/ (106 g) (4C) reduce to one

Sloan [31]

The given expression is $\frac{12500 J}{(106g)(4^{0}C )}$

This expression denotes the specific heat of a substance which indicates a heat energy of 12500 J is involved in raising the temperature of 106 g of the substance by $4^{0}C$ . Generally, the units of specific heat are $\frac{J}{g.^{0}C }$

$\frac{12500 J}{(106g)(4^{0}C )}$ = $\frac{12500 J}{(106g)(4^{0}C } = 29.5 \frac{J}{g^{0}C }$

Therefore, $\frac{12500 J}{(106g)(4^{0}C )}$ when reduced to one unit will be 29.5 $\frac{J}{g^{0}C }$

if a 1.85g mass of zinc produces 475 mL og gas and your balloon weighs 0.574 g and the room temperature is 20.5°C. calculate the

aleksley [76]

<span>You will use an ideal gas equation here. Let us denote 'x' as the unknown sample of zinc if another 1 ml of it is added to make a total of 476mL gas. The ideal gas equation is PV = nRT. Assume atmospheric conditions and then substitute everything to the equation.

(1atm)(0.476L) = (1.85 + x)(0.08206 L-atm/mol-K)(20.5+273K)
x = 1.83 g of zinc</span>

The table shows a chemical equation and the dimensional analysis used by a student to calculate the number of moles of Ba3N2 req

a_sh-v [17]

Answer:

c 3 mol of Ba(OH)₂ and 1 mol of Ba₃N₂ should be interchanged

Explanation:

Ba₃N₂ + 6H₂O → 3Ba(OH)₂ + 2NH₃

n/mol: 9.2

$\text{Moles of Ba$_{3}$N}_{2} = \text{9.2 mol Ba(OH)}_{2} \times \dfrac{\text{1 mol Ba$_{3}$N}_{2}} {\text{3 mol Ba(OH)}_{2}}= \text{x mol Ba$_{3}$N}_{2}$

They want to find moles of Ba₃N₂, so that should be in the numerator of the conversion factor,

Moles of Ba(OH)₂ should be in the denominator to cancel the units in 9.2 mol Ba(OH)₂,

What units measure heat? <br><br> What factors determine heat capacity?

guajiro [1.7K]

The heat is measured with degree Celsius and degree Fahrenheit. The heat capacity depends on both it's mass and it's chemical composition.
