Answer:
es esto OH−
Explanation:
el hidróxido es hidrógeno unido covalentemente al oxígeno. Es un anión y tiene carga negativa.
Answer:
C.) Alpha, beta, and gamma particles
Explanation:
A dense shield of aluminium can protect Cole from all the listed types of radiation produced from the radioactive particles.
A radioactive protector has very unique and specie ability to contain and prevent the movement of radiations of any types from going into the body.
The strongest and most penetrating radiations are the gamma rays. Any material that can prevent the movement of these rays can halt alpha and beta particles too.
An aluminium shield is made up of multiple layers of aluminium stacked together and it provides enough resistance.
Answer:
![K=\frac{[CaO][CH_{4}][H_{2}O ]^{2} }{[CaCO_{2}][H_{2}]^4 }](https://tex.z-dn.net/?f=K%3D%5Cfrac%7B%5BCaO%5D%5BCH_%7B4%7D%5D%5BH_%7B2%7DO%20%5D%5E%7B2%7D%20%20%7D%7B%5BCaCO_%7B2%7D%5D%5BH_%7B2%7D%5D%5E4%20%20%7D)
Explanation:
The equilibrium expression is the K value equal to the product of the concentrations of the products over the product of the concentrations of the reactants. If there is a coefficient in front of the compound, raise the molecule to that power.
Since K is big, more product is expected. This is because of mathematic principles. A large numerator with a small denominator will produce a large number.
