C8H18 + O2→ CO2 + H2O

Chemistry
1 answer:
siniylev [52]4 years ago
8 0

The balanced equation is 2C_{8} H_{18}  + 25O_{2}  ---> 16CO_{2}  + 18H_{2} O

<u>Explanation</u>:

We begin by balancing the  C  and the  H  atoms first,

             C_{8} H_{18}  + O_{2}  ---> 8CO_{2}  + 9H_{2} O

Now, counting the number of  O  atoms on either side;

reactant side  --->  2

product side  ----> 25

So,C_{8} H_{18}  + \frac{25}{2} O_{2} ---> 8CO_{2}  + 9H_{2} O

⇒  2C_{8} H_{18}  + 25O_{2}  ---> 16CO_{2}  + 18H_{2} O

How does mg2+ block the effect of extracellular calcium on neurotransmitter release?
svetlana [45]
<span>Magnesium is a strong anode than calcium. So, Mg will be oxidized into Mg2+. So instead of having Ca being the reducing agent, Mg will takes its place. That's how the "Blocking" occur.
</span><span>Without Ca2+, no neurotransmitter was released because the exocytosis of the synaptic vesicles is dependent upon Ca2+.
</span>So, when magnesium is added to the extracellular fluid it blocks the calcium channels and inhibits the release of <span>neurotransmitter.</span>

At stp,a certain mass of gas occupies a volume of 790cm3. find the temperature at which the gas occupies 1000cm3 amd has a press
Luden [163]

The temperature : 332.75 K

<h3>Further explanation</h3>

Conditions at T 0 ° C and P 1 atm are stated by STP (Standard Temperature and Pressure). At STP, Vm is 22.4 liters / mol.

volume of gas = 790 cm³ = 0.79 L

mol of gas at STP :

\tt \dfrac{0.79}{22.4}=0.035

Use ideal gas :

\tt PV=nRT

P=726 mmHg=0.955 atm

V= 1000 cm³ = 1 L

\tt T=\dfrac{PV}{nR}\\\\T=\dfrac{0.955\times 1}{0.035\times 0.082}\\\\T=332.75~K
