Answer:
A Planet
Explanation:
The earth for example, is a large body that orbits the sun, our local star
Answer:
0.5 mole
Explanation:
C=12u
O=16u
1 mole carbon dioxide=44 grams
so 22grams = 0.5 mole
Formula for density is mass / volume.
100 ml is volume. 76.5g of cooking oil is
the mass.
Therefore
76.5/100 = .765g/ml
Answer:
Explanation:
(a) Balanced reaction of gallium with oxygen is as follows:

(b) 
Multiply the carbon dioxide by 6 to balance carbon as follows:

After that multiply H2O by 7 to balance hydrogen as follows:

Finally balance oxygen by multiplying O2 by 19/2. Therefore, balanced reaction is as follows:

(c) 
first balance calcium, by multiply
by 3 as follows:

After that balance phosphorous by multiplying
by 2 as follows:

Finally balance Na by multiplying NaCl by 6. Therefore, balance reaction is as follows:

When the parallel light rays exit a convex lens, it comes away or diverge.
