Answer:

A chemical change occurred, a gas and precipitate was produced

Explanation:

From the question , we are informed of science lab, where Cash mixes two clear liquids together in a beaker. Bubbles are produced, and a white solid forms and settles to the bottom.

In this case the change that took place is chemical change ( is one where new product are formed after two substance react) the bubbles that is produced signify the presence of gas in the product, white solid formed is reffered to as a precipitate( which is reffered to as solid that is been formed from a particular solution).

How many grams are in 2.30 x 10^23 atoms in Na?
aksik [14]

There are 8.786 g

<h3>Further explanation </h3>

The mole is the number of particles contained in a substance

1 mol = 6.02.10²³

2.30 x 10²³ atoms in Na :

\tt mol=\dfrac{2.3\times 10^{23}}{6.02\times 10^{23}}=0.382

mass :

\tt mass=mol\times Ar~Na\\\\mass=0.382\times 23=8.786~g

How many kilograms of NH3 are needed to produce 1.90x10^5 of (NH4)2SO4? Answer in scientific notation
leva [86]
Molar mass :

NH₃ = 17.0 g/mol

(NH₄)₂SO₄ = 132 g/mol

2 NH₃ + H₂SO₄ = (NH₄)₂SO₄

2 x 17 g NH₃ ------------ 132 g <span> (NH</span>₄)₂SO<span>₄
</span>( mass NH₃) ------------ 1.90 x 10⁵ <span> (NH</span>₄)₂SO<span>₄

( mass NH</span>₃) = (1.90 x 10⁵) x 2 x 17 / 132
<span>
( mass NH</span>₃) = 6460000 / 132
<span>
( mass NH</span>₃) = 48939.39 g
<span>
in kg :

48939.39 / 1000 = 48.93 kg = 4.893 x 10</span>¹ kg
<span>
hope this helps!
