Gram formula mass means the <span> mass of one moles of the compound
so </span> The mass of 1.0 moles of this compound is <span>48g</span>
<span>so i conclude option 3 is correct
hope it helps</span>
A sample of water is taken and kept in a beaker in a freezer at a constant temperature of 0°C. If the system is at dynamic equilibrium, which of these statements is true?
Answer:
A current will not be induced.
Explanation:
The wire is not part of a closed circuit.
The electrical charges have no place to flow to.
Answer:
the answer is c
Explanation:
it's c because the moon has to be a full moon to be a solar eclipse when the sun moon and earth line up
The coefficient of expansion is 13 * 10^-6 m per meter length.per oK
The temperature difference = 42 - - 8 = 50 oC
delta T = (42 + 273) - (-8 + 273) = 50 oK
delta L = L * 13* 10^6 m/oK
oK = 50 oK delta L = 19.5 cm = 19.5 cm [1m / 100 cm] = 0.195m
So we need to find the length and it is computed by:
0.195= L * 13 * 10^-6 * 50 L = 0.195 / (13*10^-6*50) L = 300 m
