Answer: Elements are arranged from fewest protons to most protons.
Explanation:
The question is incomplete, the complete question is;
A block is pulled 0.90 m to the right in 2.5 s. What is the blocks average speed to the nearest hundredth of a m/s
Answer:
0.36 m/s to the hundredth place
Explanation:
Now let us remember the definition of speed. Speed is defined in physics as distance/time.
Here we have the distance as 0.9 m
We have the time as 2.5 s
Hence the average speed is obtained from;
Speed = 0.9/2.5 = 0.36 m/s to the hundredth place
Answer:
5.00 moles O₂
General Formulas and Concepts:
<u>Chemistry - Atomic Structure</u>
- Using Dimensional Analysis
- Avogadro's Number - 6.022 × 10²³ atoms, molecules, formula units, etc.
Explanation:
<u>Step 1: Define</u>
3.01 × 10²⁴ molecules O₂
<u>Step 2: Convert</u>
= 4.99834 moles O₂
<u>Step 3: Check</u>
<em>We are given 3 sig figs. Follow sig fig rules and round.</em>
4.99834 moles O₂ ≈ 5.00 moles O₂
Answer:
Endergonic
Explanation:
Endergonic reactions are reaction that requires a particular amount of energy to initiate the reaction. If there is no energy, the reaction will not occur.
The answer is : 28.01 .. I know this because I just did this !
