Answer:
Garnet is a hard transparent mineral that is often used as gemstones and abrasives and quartz is the most abundant mineral on the earth's surface. They are both minerals that come out of the earth and that's about the most they have in common.
Explanation:
I got this answer correct.
Answer:
a) 74.87 % carbon
Explanation:
Molecular mass of CH₄ is 16.042 g / mole.
Now we divide the following reasoning for 1 mole of methane:
if in 16.042 g of CH₄ there are 12.01 g of carbon
then in 100 g of CH₄ there are X g of carbon
X = (100 × 12.01) / 16.042= 74.87 % carbon
Answer:
<em>Mass number = protons + neutron</em>
<em />
<em>The mass number of an element is the sum of the protons and neutrons. The number of neutrons for a given element is the only number that can change and still have the identity of the element stay the same, (because the atomic number is the number of protons).
</em>
<em>
</em>
<em>In this case the mass number would be 11</em>

Answer : Option C) It explained the odds of finding the position of an electron.
Explanation : Schrödinger's theory of the atomic model is true for the probability of finding the electron around the nucleus. Schrödinger used odd mathematical equations to describe the likelihood of finding an electron in a certain position around the nucleus. This atomic model was known as the quantum mechanical model of the atom. He posed an equation which is now called as the Schordinger’s Wave Equation, which incorporates both the wave-like and particle-like behaviors of electrons, which stated that electrons can act like waves/light and particles. Which later helped to develop the uncertainty principle for finding the probable position of the electron.
Answer : To balance a chemical equation you need to find the same number of molecules on both the sides of the reaction.
Here in the reaction ;
here we can see that I is not balanced so we need to balance that,
also nitrate is unbalanced we need to work on that as well.
so on solving we get,
