What term describes gas that is compressed into a smaller space than it would normally occupy at Earth's surface?
Aloiza [94]

Pressurized gas is the term that is used to describe a gas that is compressed into a smaller space than it would normally occupy at Earth's surface.

Explanation:

The purpose of compressing a gas is to lessen its volume so that it can fit in a small space. Natural gas can be compressed using a compressor and the pressure of a compressed gas is 200 to 250 bars.

Pressurized gases are used in ground processing and space flight operations.  Pressurized gas, also known as compressed gas is also used in fuel production and in gas pipelines.

When stored in a reservoir, care must be taken to avoid leakage as these gases compressed under high pressure are highly flammable.

Zn+HCI = ZnCI2 + H2​
anygoal [31]
<h3>Answer:</h3>

#1. Type of reaction: Single displacement

#2. Balanced equation: Zn + 2HCI → ZnCI₂ + H₂

<h3>Explanation:</h3>

<u>We are given;</u>

  • The equation; Zn+HCI → ZnCI₂ + H₂

Assuming we are required to identify the type of reaction and balance it;​

  • The reaction is a <u>single displacement reaction.</u>
  • Zinc metal displaces hydrogen atom from hydrochloric acid to form a salt, zinc chloride and hydrogen gas.
  • To balance the equation, we put coefficients on the reactants and products for the number of atoms of each element to be equal on both sides of the equation.
  • In this case, the appropriate coefficients are 1, 2, 1 and 1
  • Therefore, the balanced equation will be;

Zn + 2HCI → ZnCI₂ + H₂

Caustic soda is 19.1 M NaOH and is diluted for household use. What is the household concentration if 10 mL of the concentrated s
olga nikolaevna [1]
Hello!

To calculate the household concentration of NaOH we need to use the dilution formula, clearing for M2, as you can see in the equation below:

M1*V1=M2*V2 \\ \\ V2= \frac{M1*V1}{V2}

Now, we input the values from the data we have onto this equation. M1=19,1 M; V1=10 mL; V2=400 mL, and solve the equation to get the result:

V2= \frac{M1*V1}{V2}= \frac{19,1M*10mL}{400 mL}=0,48M

So, the household concentration of NaOH will be 0,48 M

Have a nice day!
