2 h2o ( g) 2 h2 (g) + o2 (g) kp = 7.8 × 10-16 at 930 k. give the value of kp for this reaction, if it is written as: 1/2o2 (g) +
trapecia [35]
When multiplying by a constant, raise Kp to the power of that constant.

When the reaction is reversed, it gives the inverse of Kp.

Kp^(-1/2) = (7.8 x 10^-16)^(-1/2) = 3.6 x 10^7

Balance the following reaction: _Na3PO4+_Ca(NO3)2-->_NaNO3+_Ca3(PO4)2
erica [24]

The balanced equation

2Na₃PO₄+3Ca(NO₃)₂⇒6NaNO₃+Ca₃(PO₄)₂

<h3>Further explanation</h3>

Given

Reaction

_Na3PO4+_Ca(NO3)2-->_NaNO3+_Ca3(PO4)2

Required

Balanced equation

Solution

Give a coefficient

aNa₃PO₄+bCa(NO₃)₂⇒cNaNO₃+Ca₃(PO₄)₂

Ca, left=b, right = 3⇒ b=3

P, left=a, right = 2⇒a=2

Na, left=3a, right=c⇒3a=c⇒3.2=c⇒c=6

The equation becomes :

2Na₃PO₄+3Ca(NO₃)₂⇒6NaNO₃+Ca₃(PO₄)₂

a stock solution has a concentration of 0.30 m clo2 and is diluted to become a 0.20 m solution with a volume of 0.050 l. what wa
Pavlova-9 [17]

The stock solution has a volume of 0.208L. When diluted, a stock solution with a concentration of 0.30 m clo2 becomes a 0.20 m stock solution with a volume of 0.050.

A three-dimensional space's occupied volume is measured. It is frequently measured numerically with SI-derived units (such the cubic metre and litre) or with other imperial units (such as the gallon, quart, cubic inch). Volume and length are related in how they are defined (cubed).

A highly concentrated stock solution, often prepared as a 10x concentrated solution, can be described as a stock solution since it can be diluted to create a working solution. In order to prepare complex solutions with numerous constituents, stock solutions can also be utilized as a component.

0.3M*v = 0.125M*0.50L

V=0.208L
