Answer:

NCl₃ + 2 H₂O = HNO₂ + 3 HCl

Explanation:

Let's consider the unbalanced equation showing the reaction between nitrogen trichloride and water to form nitrous acid and hydrochloric acid.

NCl₃ + H₂O = HNO₂ + HCl

We start balancing Cl atoms by multiplying HCl by 3.

NCl₃ + H₂O = HNO₂ + 3 HCl

Then, we balance O atoms by multiplying H₂O by 2.

NCl₃ + 2 H₂O = HNO₂ + 3 HCl

The equation is now balanced.

Calculate q (in units of joules) when 1.850 g of water is heated from 22 °C to 33 °C. Report only the numerical portion of your
Minchanka [31]
When q is the heat energy in joules (J)

so, according to this formula, we can get q (in joule unit):

q = M*C*ΔT

when M is the mass of the water sample = 1.85 g

C is the specific heat capacity of water = 4.18 J/g.°C

and Δ T is the difference in temperature (Tf-Ti) = 33 - 22 = 11°C

So, by substitution, we will get the value of q ( in Joule):

∴ q = 1.85 g * 4.18 J/g.°C * 11 °C

      = 85 J

Your solution has a volume of 36 ml and a mass of 970 g. what is the density of your solution
LenaWriter [7]

Answer:

The answer is

<h2>26.94 g/mL</h2>

Explanation:

The density of a substance can be found by using the formula

density =  \frac{mass}{volume}  \\

From the question

mass = 970 g

volume = 36 mL

The density of the object is

density =  \frac{970}{36}  \\ 26.944444...

We have the final answer as

<h3>26.94 g/mL</h3>

Hope this helps you
