23.458 g

<h3>Further explanation</h3>

Given

Reaction

H2SO4 + 2NaNO2 → 2HNO2 + Na2SO4

24.14714 g of Na2SO4

Required

mass of NaNO2

Solution

mol Na2SO4 :

= 24.14714 : 142,04 g/mol

= 0.17

From the equation, mol NaNO2 :

= 2/1 x mol Na2SO4

= 2/1 x 0.17

= 0.34

Mass NaNO2 :

= 0.34 x 68,9953 g/mol

= 23.458 g

A dialysis unit requires 70000 mL of distilled water. How many gallons of water are needed? (1 gal = 4 qt)
Lady bird [3.3K]

Answer: 19.25 gallons

Explanation: 1 ml = 0.0011 quart

Given:  4 quarts = 1 gallon

Thus if 1 ml is equal to 0.0011 quart

70000 ml  is equal to =\frac{0.0011}{1}\times 70000=77quart

Now if 4 quarts is equal to 1 gallon.

77 quarts is is equal to=\frac{1}{4}\times 77=19.25gallons

Which atomic model shows the atom as a positively charged sphere with negatively charged electrons spread throughout
tankabanditka [31]

Answer:

B) Thomson's Model

Explanation:

Dalton's Model simply consisted of small spheres that represented atoms, and Bohr's model had a nucleus in the center with electrons orbiting in strict orbits, not randomly spread throughout. Thomson's plum pudding model, however, had an overall positively charged atom with many electrons spread throughout. If you search up "Plum Pudding Model" you can visually understand this.

For the following reaction, predict whether the equilibrium lies predominantly to the left or to the right. Explain.
Likurg_2 [28]

Answer:

Lies predominantly to the left.

Explanation:

In the reaction:

NH4⁺(aq) + Br-(aq) ⇄ NH3(aq) + HBr(aq)

Conjugate acid + Ion ⇄ weak base + strong acid

HBr is a strong acid whereas NH3/NH4⁺ are the weak base and its conjugate base. A strong acid as HBr dissociates completely in solution as H⁺ and Br⁻. That means in solution you will never have HBr without dissociation doing the reaction:

<h3>lies predominantly to the left.</h3>
