4.45x10
Step-by-step explanation:
Solution
<h3>V= π r squared h=π·10872·12≈4.45441×10 7 times </h3><h3 /><h3>Im pretty sure thats the answer </h3>
Step-by-step explanation:
Hey there! Down here :D
![\bf{Ca + O_2 \longrightarrow CaO}](https://tex.z-dn.net/?f=%20%5Cbf%7BCa%20%2B%20O_2%20%5Clongrightarrow%20CaO%7D)
Now , let's balance it by Multiplying 2 on Calcium Side.
![\sf{2Ca + O_2 \longrightarrow 2CaO}](https://tex.z-dn.net/?f=%20%5Csf%7B2Ca%20%2B%20O_2%20%5Clongrightarrow%202CaO%7D)
Is the Required Equation.
Hope it helps :)
<h3>Redox Reaction: Is it?</h3>
Yes, this is because:-
![\sf{2Ca + O_2 \longrightarrow 2CaO}](https://tex.z-dn.net/?f=%20%5Csf%7B2Ca%20%2B%20O_2%20%5Clongrightarrow%202CaO%7D)
- Here, Calcium acts as Reducing Agent
- And Oxygen is oxidizing agent.
- And also, Cao gets oxidized.
It is also a Combination reaction.
![\sf{A + B \longrightarrow AB}](https://tex.z-dn.net/?f=%20%5Csf%7BA%20%2B%20B%20%5Clongrightarrow%20AB%7D)
- Here A is Calcium
- Here B is Oxygen.
You said you was gonna hut me down so whats up BlTCH
You will need to know that the sum of "two complementary angles" is 90
therefore
Let x = one angle
then
90-x = second angle
.
Now, we construct our equation based on the sentence:
"The sum of the measures of two complementary angles exceeds the difference of their measures by 86°."
x + 90-x = x-(90-x)+86
90 = x-90+x+86
90 = 2x-90+86
90 = 2x-4
94 = 2x
47 degrees = x (first angle)
.
Second angle:
90-x = 90-47 = 43 degrees (second angle) hope it helps
