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:
One mole
Explanation:
The balanced chemical equation is
<u>1</u>NaOH + <u>1</u>HNO₃ ⟶ NaNO₃ + H₂O
<u>1</u> mol <u>1</u> mol
The coefficients in front of the formulas tell you the amount of something that reacts with an equivalent amount of something else.
In this reaction, 1 mol NaOH reacts with 1 mol HNO₃.
Answer:
0.86L.
Explanation:
1mol of Zn has mass of 65.39g . The amount of Zn is 2.5g65.39g/mol=0.038mol
