What is the specific heat of silicon if the temperature of a 4.11 g sample of silicon

Chemistry
1 answer:
monitta3 years ago
4 0

Answer:

The right solution is "0.7107 J/g°C".

Explanation:

The given values are:

Mass,

m = 4.11 g

Temperature,

ΔT = 3.8°C

Heat,

Q = 11.1 J

The specific heat of silicon will be:

⇒  C=\frac{Q}{m \Delta T}

On substituting the values, we get

⇒      =\frac{11.1}{4.11\times 3.8}

⇒      =\frac{11.1}{15.618}

⇒      =0.7107 \ J/g^{\circ}C

A 17g sample of H2O2 was decomposed to yield 1g of H2 and 16g of O2 An unknown sample containing only H and O was decomposed to
ludmilkaskok [199]

Answer:

Explanation:

Our H_2O_2 sample yielded 1g of H_2 and 16g of O_2, but our unknown sample yielded 2 times as much H_2  for the same amount of O_2.

What does this mean? that the H:O proportion for the unknown sample is twice the H:O proportion for the H_2O_2 sample.

What is the  H:O proportion for the H_2O_2 sample? As we can see from its formula, it's 1:1, therefore the proportion for the unknown formula must be 2:1.

That means, two H atoms for every O atom. We could write that as: H_2O and you should recognize that formula, for it is one of the most common compounds on earth, Water.

How many oxygen atoms are in 3.70 g of quartz?
Ad libitum [116K]

Answer:

The formula of Quartz is SiO2. So, 1 mole of Quartz will have 2 moles of oxygen atoms, i.e. 2 x 6.022 x 10^23 atoms of oxygen. The molar mass of quartz is 60 g per mol. So, 60 g quartz means 1 mole quartz.
