Answer:
D
Explanation:
The weight of an object will change if the object is brought farther away from Earth, or placed on a different planet since the force of gravity on the object will change. However, the mass of the object will remain the same regardless of whether the object is on Earth, in outer space, or on the Moon. hope this helps have a good day :)
Full moon
A lunar eclipse can occur only at full moon. A total lunar eclipse can happen only when the sun, Earth and moon are perfectly lined up — anything less than perfection creates a partial lunar eclipse or no eclipse at all.
In gaseous particles are slightly lighter than those in pasma which look like liquid
Answer:
3.79 moles
Explanation:
To convert moles to gams of a substance we need to find the molar mass of the substance. For Ca(OH)₂ th molar mass is:
1Ca = 40.08g/mol
2O = 2*16g/mol = 32g/mol
2H = 2*1.01g/mol = 2.02g/mol
The molar mass is:
40.08g/mol + 32g/mol + 2.02g/mol = <em>74.1g/mol</em>
<em />
And moles are:
281g * (1mol / 74.1g) =
<h3>3.79 moles</h3>
