How can you minimize a collision summary
ElenaW [278]

One of the ways to minimize a collision is to slow down: When you can't find an escape and you're definitely going to collide with something, you should slow your vehicle down as much as possible.

Hope this helps ^^

Pb(NO3)2+K2CrO4 --&gt; PbCrO4+KNO3 <br> How do you balance this?
belka [17]

Answer:

Pb(NO₃)₂ + K₂CrO₄ ⟶ PbCrO₄ + 2KNO₃

Step-by-step explanation:

The unbalanced equation is

Pb(NO₃)₂ + K₂CrO₄ ⟶ PbCrO₄ + KNO₃

Notice that the complex groups like NO₃ and CrO₄ stay the same on each side of the equation.

One way to simplify the balancing is to replace them with a single letter.

(a) For example, let <em>X = NO₃</em> and <em>Y =CrO₄</em>. Then, the equation becomes

PbX₂ + K₂Y ⟶ PbY + KX

(b) You need 2X on the right, so put a 2 in front of KX.

PbX₂ + K₂Y ⟶ PbY + 2KX

(c) Everything is balanced. Now, replace X and Y with their original meanings.  The balanced equation is

Pb(NO₃)₂ + K₂CrO₄ ⟶ PbCrO₄ + 2KNO₃
