1. The trees' large surface area and porous characteristic pulls in more oxygen that fuels fire. Often, trees are positioned near curtains, presents, furniture, or rugs, which can quickly catch fire too, spreading fire quickly throughout a home.

2. Water is a natural conductor of electricity and if you throw water on an electrical fire, you can get shocked or electrocuted. Also, water may enable to fire to spread by conducting electricity throughout the room and potentially igniting flammable materials.

Explanation:

1. Under the influence of heat, wood produces easily substances that react eagerly with oxygen, leading to the high propensity of wood to ignite and burn.

2. Water is a natural conductor of electricity and if you throw water on an electrical fire, you can get shocked or electrocuted. Also, water may enable to fire to spread by conducting electricity throughout the room and potentially igniting flammable materials.

When 3.00 moles of hydrogen molecules and 1.50 moles of oxygen molecules react, they form 3.00 moles of water according to the r
Lynna [10]

Answer:

54.0 g.

Explanation:

  • From the given data and the balanced reaction:

<em>2H₂ + O₂ → 2H₂O.</em>

<em></em>

When 3.00 moles of hydrogen molecules and 1.50 moles of oxygen molecules react, they form 3.00 moles of water according to the balanced reaction.

<em>∴ The no. of grams in 3.0 moles of water = no. of moles x molar mass </em>= (3.0 mol)(18.0 g/mol) = <em>54.0 g.</em>

Write an equation showing how this buffer neutralizes added base (ba(oh2.
Crank
Ba(OH)2 can be neutralized by adding an acid to the solution. We can add HCl to produce:

Ba(OH)2 + 2HCl ===> BaCl2 + 2H2O ; producing a salt BaCl2 and water. 

or we can add H2SO4 to produce:

Ba(OH)2 + H2SO4 ===> BaSO4 + 2H2O; producing a salt, BaSO4, and water. <span />

Density = Mass over Volume

  • D = m/V
<h3>Explanation:</h3>

<u>Step 1: Define</u>

D = 25 g/cm³

m = 100 g

<u>Step 2: Solve for </u><em><u>V</u></em>

  1. Substitute variables [D]:                    \displaystyle 25 \ g/cm^3 = \frac{100 \ g}{V}
  2. Multiply <em>V</em> on both sides:                  \displaystyle V(25 g/cm^3) = 100 \ g
  3. Isolate <em>V</em>:                                            \displaystyle V = 4 \ cm^3
