it will sink
Explanation:
the solid iron will sink because it is dense than the liquid iron I will sink and it will melt
What’s the question Bc I don’t understand what u are trying to ask
Answer:
Explanation:
The frequency and the wavelength of a wave are related by the equation
where
v is the speed
f is the frequency
is the wavelength
For the sound wave in this problem, we have
f = 634 Hz (frequency)
(wavelength)
Therefore, the speed of the wave is
The speed of sound in air depends on the temperature according to the equation
where T is the temperature.
In this problem, we know the speed, so we can calculate the temperature:
Answer:
167,3 grams of O2 (g)
Explanation:
According to the following balanced equation:
C3H8 + 5 02 ---> 3 CO2 + 4 H20
We calculate the mass of the moles:
5 mol O2 = 16grams/mol x2x 5= 160 grams/mol
1 mol C3H8= 3 x12 grams/mol + 8 x 1 gram/mol= 44 grams/mol
If 44 grams C3H8 react with--------- 160 grams O2
46 gramsC3H8 react with --------X = (46x160)/44 =167, 3 grams O2
