Answer:

The answer to your question is: False, it is an exothermic reaction.

Explanation:

Endothermic reactions needs energy (heat) to happen. Heat is added to the reactants.

Exothermic reactions releases heat, heat is represented in the products.

2C2H2 + 5O2 → 4CO2 + 2H2O + 310 kcal

In this reaction, we notice that 310 kcal is positive and is in the products so this reaction is exothermic.

Which is a spectator ion involved in the reaction of k2cro4(aq) and ba(no3)2(aq)?

forsale [732]

K₂CrO₄(aq) + Ba(NO₃)₂(aq) = BaCrO₄(s) + 2KNO₃(aq)

2K⁺ + CrO₄²⁻ + Ba²⁺ + 2NO₃⁻ = BaCrO₄ + 2K⁺ + 2NO₃⁻

spectator ions: K⁺, NO₃⁻

At what temperature do kno3 and nacl have the same molar solubility

Veseljchak [2.6K]

We are asked to solve the temperature do Potassium Nitrate KNO3 and Sodium Chloride NaCl has the same molar solubility. The answer is 44.5 degrees Celsius. As per the definition of solubility temperature, the solubility increases when the temperature increases where molecules are allowed to move faster at a higher temperature.

You have two containers at 25°C and 1 atm. One has 22.4 L of hydrogen gas, and the other has 22.4 L of oxygen gas.

olga_2 [115]

Both containers have the same number of molecules= 5.62 x 10²³

<h3>Further explanation</h3>

Given

22.4 L of hydrogen gas

22.4 L of oxygen gas

25°C and 1 atm.

Required

true statement

Solution

Conditions at T 25 ° C and P 1 atm are stated by RTP (Room Temperature and Pressure). Vm in this condition = 24 liters / mol

and from Avogadro's Law :

<em>At the same temperature and pressure, the ratio of gas volume will be equal to the ratio of gas moles </em>

So two gas have the same molecules

1 mol = 6.02 x 10²³ molecules

24 L = 1 mol, so for 22.4 L :

$\tt \dfrac{22.4~L}{24~L}\times 6.02\times 10^{23}~molecules=5.62\times 10^{23}~molecules$
