Answer:
precipitation is when water flows into the ground
Explanation:
.................
Answer:
The answer is
<h2>0.59 g/cm³</h2>
Explanation:
To find the density of the sphere we use the formula
<h2>
</h2>
To find the density in g/cm³ first convert the mass into grams and the volume into cm³
For the mass we have
155 lb = 70306.82 g
For the volume
4.2 ft³ = 118930.76 cm³
Substitute the values into the above formula
That's
<h2>
</h2>
We have the final answer as
<h3>Density = 0.59 g/cm³</h3>
Hope this helps you
Answer is D.
Among the given options, the products of equation A, B and C are aqueous solutions. Those are indicated by using (aq).
The balanced equation for the reaction between Li₂CO₃(aq) and FeCl₂(aq) is Li₂CO₃(aq) + FeCl₂(aq) → 2LiCl(aq) + FeCO₃(s)
LiCl is a salt while FeCO₃ is a Grey/green color precipitate. Hence, option D represents a precipitation reaction.
Here we have to point out the necessary character of the substance needed which are used as lightning conductor.
The substance should have the following properties:
High electricity carrying capacity and less resistant.
High melting point
The substance should have high electricity carrying capacity or the resistance is less so that the electricity generated during the lightning easily conducted to the ground
The substance should have high melting point so that during lightning the generated high temperature cannot disrupt the material.
The correct answer is B.
1 mol O2 x 15.999 O2/ 1 mol O2 = 15.999 O2
16 O2 when rounded.
