1) the sun (greek name Helios gives heliocentric)
2) A. Newton's laws of motion can prove this as well as Kepler's Laws
3) D. Inertia keeps it from falling onto the sun and gravity keeps it from going off in a straight line
4) moons. They orbit planets not suns directly
5) B (International Space Station gives a hint)
Answer:
a sound wave is an electromagnetic wave
Answer:
The maximum mass of water that could be produced by the chemical reaction is 10.1 g
Explanation:
The equation of reaction involves the combustion of 2 moles of hexane (C6H14) with 19 moles of oxygen (O2) to produce 12 moles of carbon dioxide (CO2) and 14 moles of water (H2O)
From the equation of reaction above,
2 moles of C6H14 (172 g) produced 14 moles of H2O (252 g)
6.9 g of C6H14 would produce (6.9×252/172) = 10.1 g of water (to 3 significant figures)
Also, from the equation of reaction,
19 moles of O2 (608 g) produced 14 moles of H2O (252 g)
17.3 g of O2 would produce (17.3×252/608) = 7.17 g of water (to 3 significant figures)
Maximum mass of water produced = 10.1 g
C. 16 times
Because depending on this ... (4)^2= 16
And (1)^2 =1
