<span>The electron transport process makes water and ATP and is sometimes called Oxidative phosphorylation because it requires oxygen.</span>
Answer:
In a Lewis symbol, the symbol for the element is used to represent the atom and its core electrons. Dots placed around the atom are used to indicate the valence electrons. ... In 1916, Gilbert Newton Lewis, an American chemist, suggested that molecules were formed when atoms shared pairs of outer electrons.
Explanation:
KOH + H2SO4 —> K(+) + HSO4(-) + H2O
Or a total reaction
2 KOH + H2SO4 —> 2 K(+) + SO4(2-) + 2 H2O
Number of significant figures will be 1.
Given:
weight of acetylsalicylic acid = 0. 4g
Significant figures are the digits of value which carry meaning towards the resolution of the measurement. They are also called significant figures in chemistry. All the experimental measurements have some kind of uncertainty associated with them.
When we convert 0.4g acetylsalicylic acid to mg we get value 400mg
when we convert 400mg to gram we get value of 0.4 gram
Since 0 before a decimal is not significant so there is only one significant figure that is 4.
<h3>How do you determine the number of significant figures?</h3>
- The zero to the left of a decimal value less than one is meaningless.
- All trailing zeros that are placeholders are meaningless.
- The presence of zeros between non-zero numbers is significant.
- Non-zero numbers are all significant.
- If a number contains more digits than the desired number of significant digits, it is rounded.
<h3>Why 'Hidden Figures' is so important?</h3>
It's an important story for a variety of reasons, and it comes at a time when people are looking to Hollywood more than ever to tell stories that represent them. Hidden Figures is that movie for many, and it's critical that everyone sees these women in action. This is why. This film tells a story that you've probably never heard before.

Answer:1962kJ
Explanation:
m=2000 kg
h=100m
G=9.81m/s²
GPE=m*G*h
GPE=2000kg*100m*9.81m/s²=1,962,000J=1962 kJ
