<span>The answer should be false, because mass should not have to do with how bright a star is </span>

The brightness of a star is measured as luminosity. It is a simple factor of energy emitted by a star in a unit time or generally per second.

the following factors may affect the brightness of a star

a) Temperature of star

b) size of star: larger the size more the brightness

c) distance from observer : closer the star brighter it will appear

so massive stars or stars with large mass have lower absolute brightness will be false.

Explanation:

First to show combustion, you use O₂.

So C₆H₁₀O₅ + O₂ is the reaction. Assuming complete combustion, all you get as products are CO₂ and H₂O. Then you have to balance the full reaction.

C₆H₁₀O₅ + 6O₂ -----> 6CO₂ + 5H₂O

What is the expected mass (in kg) of a 10 over 5 B isotope? 1 proton = 1.6726 × 10-27 kg 1 neutron = 1.6749 × 10-27 kg A.1.67 ×

$^{10}_5 B$
An atom of this isotope contains 5 protons and 10-5=5 neutrons.

$5 \times 1.6726 \times 10^{-27} + 5 \times 1.6749 \times 10^{-27} = \\
8.363 \times 10^{-27} + 8.3745 \times 10^{-27}= \\
16.7375 \times 10^{-27}= \\
1.67375 \times 10^{-26} \approx \\
1.67 \times 10^{-26}$

The answer is A. 1.67 × 10⁻²⁶ kg.
