5.5/-38 / 5.5 = 1/-6.9 x 1.3 = 1.3/-8.98
unit volume/temperature x searching amount

i’d say the temperature would be -8.98 C simply - I don’t know what formula youd use for this

1) A box has a mass of 8 kg and a volume of 2 m? What is its density? |
pentagon [3]

\huge\boxed{4\ \text{kg/m$^3$}}

We know that \rho=m\div V, where \rho is density, m is mass, and V is volume.

Substitute in the values we know and solve:

\begin{aligned}\rho&=8\div2\\&=\boxed{4}\end{aligned}

what is the molarity of a solution made by dissolving 18.5 grams of NaCL into enough water to reach 450.0ML​
ValentinkaMS [17]

Answer:

0.702M

Explanation:

Molarity of a solution, which refers to the molar concentration of that solution can be calculated thus;

Molarity = number of moles (n) ÷ volume (V)

Firstly, we convert 18.5 grams of NaCl to moles using the formula; mole = mass/molar mass

molar mass of NaCl = 23 + 35.5 = 58.5g/mol

mole = 18.5/58.5

mole = 0.32moles

Volume of water (V) = 450mL = 450/1000 = 0.450L

Molarity = n/V

Molarity = 0.32/0.450

Molarity = 0.702M

Which equation represents a neutralization reaction?
Law Incorporation [45]

3. Ca(OH)₂ + H₂SO₄ → CaSO₄ + 2 H₂O represents a neutralization reaction.

<u>Explanation:</u>

Neutralization reaction is a reaction in which an acid reacts with a base to form a slat and water.

First reaction is the decomposition reaction in which the reactant is decomposed to form 2 or more products.

Second one is the combustion reaction in which methane is burnt in presence of oxygen.

Third one is the Neutralization reaction, in which calcium hydroxide (base) reacts with sulfuric acid (acid) to form a (salt) calcium sulfate and water.

Fourth reaction is nothing but the double displacement reaction in which the ions exchanged their positions there by forming two new products.
