Answer:
because you are a living organism. you also have feeling.
Answer:
(102 900 ÷ 12) + (170 × 1.27) = 8800
Step 1. Evaluate the expressions inside the parentheses (PEMDAS)
102 900 ÷ 12 = 8575
170 × 1.27 = 215.9
In multiplication and division problems, your answer can have no more significant figures than the number with the fewest significant figures.
Thus, the underlined digits are not significant, but we keep them in our calculator to avoid roundoff error.
Step 2. Do the addition (PEMDAS).
8575
+ 215.9
= 8790.9
Everything that you add to an insignificant digit gives an insignificant digit as an answer.
Thus, the underlined digits are not significant.
We must drop them and round up the answer to 8800.
Explanation:
There are three subatomic particle that are present in an atom. These are electrons, protons, and neutrons. Among these three, I believe the <span>subatomic particle that plays the greatest part in determining the properties of and element would be the electron. It is what determines how the element would react in different conditions.</span>
Answer:
yes the Bohr model predicts their spectra accurately
Explanation:
The Bohr model based on one electron system
The atom H has a single atom and the ion Be+3 has a single atom as well and this proves that the Bohr model predicts their spectra accurately .
also apply the equation model to further explain
E = 
z = atomic number
for H the value of z = 1
for Be+3 the value of z = 4
when this values are substituted into the equation above
E = 
, E = 
this results show that the energy level of Be+3 is higher than the energy level of H by a factor of 16 , and this shows that their line patterns are similar
Mass is a coherent, typical large body of matter with no definite shape. Another way to describe matter is a very heavy or large object.Matter can also be described with length. This is how i know matter is a very large length or weight. (Hope this helped) :)
