The presence of an atmosphere, temperature, and distance from the Sun do not affect a planet's gravity. Are the objects in the solar system still or are they in motion? The Sun's gravity pulls the planets in orbit around it, and some planets pull moons in orbit around them.
A substance that donates electrons to form a covalent bond. So the answer is B
First, write out a complete balanced reaction for the combustion of ethane, ethane + O2 -> CO2 + H20. Then, divide the grams of ethane by its Molar Mass and multiply by 32, the molar mass of O2.
Answer: 6.75 moles of 
can be produced from 13.5 moles Na
Explanation:
The balanced chemical equation for formation of from Na is:
According to stoichiometry :
4 moles of Na give = 2 moles of
Thus 13.5 moles of 
give =
of
Thus 6.75 moles of can be produced from 13.5 moles Na
Well that's a not easy task. <span>The specialized forecasters analyze near-real-time ground- and space-based observations to assess the current state of the solar environment which includes the areas from the Sun to the Earth and points in between. Space weather forecasters also analyze the pattern of solar activity. </span>
