Answer:

M_{acid}=0.075M

Explanation:

Hello!

In this case, since the reaction between NaOH and HNO3 is:

NaOH+HNO_3\rightarrow NaNO_3+H_2O

Whereas there is a 1:1 mole ratio between the acid and base, thus, we can write:

M_{acid}V_{acid}=M_{base}V_{base}

In such a way, solving for the concentration of the acid, HNO3, we obtain:

M_{acid}=\frac{M_{base}V_{base}}{V_{acid}}

Therefore, by plugging in we obtain:

M_{acid}=\frac{0.12L*0.2M}{0.32L}\\\\ M_{acid}=0.075M

Best regards!

What is the arrhenius definition of an acid
irga5000 [103]
An Arrhenius acid is a substance that dissociates in water to form hydrogen ions (H+). In other words, an acid increases the concentration of H+ ions in an aqueous solution. This protonation of water yields the hydronium ion (H3O+); in modern times, H+ is used as a shorthand for H3O+ because it is now known that a bare proton (H+) does not exist as a free species in aqueous solution.

How many calories of heat are needed to raise the temperature of 33.0 g of diethyl ether from 14.0 ∘C to 25.0 ∘C ?
Xelga [282]

The amount of heat (in calories) needed to raise the temperature is 324.885 calories

<h3>How to determine the temperature change </h3>

We'll begin by obtaining the temperature change. This can be obtained as followed:

  • Initial temperature (T₁) = 14 °C
  • Final temperature (T₂) = 25 °C
  • Change in temperature (ΔT) = ?

ΔT = T₂ - T₁

ΔT = 25 - 14

ΔT = 11 °C

<h3>How to determine the heat (in Calories)</h3>

The amount of heat needed to raise the temperature can bee obtaimedals follow:

  • Mass (M) = 33 g
  • Change in temperature (ΔT) = 11 °C
  • Specific heat capacity (C) of diethyl ether = 0.895 cal/g°C
  • Heat (Q) =?

Q = MCΔT

Q = 33 × 0.895 × 11

Q = 324.885 calories

Thus, the amount of heat needed is 324.885 calories
