Answer:
If an atom looses all of its electrons then it will become positively charged. It will also turn into an Ion.
Explanation:
Answer:
The answer is option a. The evaporation of water from the skin
Explanation:
An endothermic reaction is any synthetic reaction that retains heat from its environment. The ingested energy gives the enactment energy to the reaction to happen.
No new bonds formed, no bonds broken in this example. water molecules go from liquid to vapour (gas ), intermolecular bond exist between polar (-OH) molecules and energy is required to break these bonds during the change from liquid to gas. So, it is endothermic .
Remaining three above examples are exothermic. combustion of gas releases energy(exothermic). burninig of the candle exothermic because the energy released from the oxygen into carbon dioxide and water.oxidation of iron also exothermic
There are 3 atoms in 1 molecule of Co2.
The answer is A, enzymes allow reactions to proceed at body temperature.
Answer:
concentration of ![[O_2]](https://tex.z-dn.net/?f=%5BO_2%5D)
= 0.0124 = 12.4 ×10⁻³ M
concentration of ![[CO]](https://tex.z-dn.net/?f=%5BCO%5D)
= 0.0248 = 2.48 ×10⁻² M
concentration of ![[CO_2]](https://tex.z-dn.net/?f=%5BCO_2%5D)
= 0.4442 M
Explanation:
Equation for the reaction:
⇄ 
+ 
Concentration of 
= 
= 0.469
For our ICE Table; we have:
⇄ +
Initial 0.469 0 0
Change - 2x +2x +x
Equilibrium (0.469-2x) 2x x
K = ![\frac{[CO]^2[O]}{[CO_2]^2}](https://tex.z-dn.net/?f=%5Cfrac%7B%5BCO%5D%5E2%5BO%5D%7D%7B%5BCO_2%5D%5E2%7D)
K = ![\frac{[2x]^2[x]}{[0.469-2x]^2}](https://tex.z-dn.net/?f=%5Cfrac%7B%5B2x%5D%5E2%5Bx%5D%7D%7B%5B0.469-2x%5D%5E2%7D)
Since the value pf K is very small, only little small of reactant goes into product; so (0.469-2x)² = (0.469)²
![x=\sqrt[3]{1.9929*10^{-6}}](https://tex.z-dn.net/?f=x%3D%5Csqrt%5B3%5D%7B1.9929%2A10%5E%7B-6%7D%7D)
x = 0.0124
∴ at equilibrium; concentration of = 0.0124 = 12.4 ×10⁻³ M
concentration of = 2x = 2 ( 0.0124)
= 0.0248
= 2.48 ×10⁻² M
concentration of = 0.469-2x
= 0.469-2(0.0124)
= 0.469 - 0.0248
= 0.4442 M
