HC1 solution is mostly water. NaOH solution is mostly water. When 50mL of HC1 is mixed with 50mL of NaOH, what is the final mass
elixir [45]
Since water has a density of about 1g/mL, and we are assuming HCl and NaOH are mostly water, the total mass of the 2 solutions is 100 g.
Due to the conservation of mass, the mass of product must equal the total mass of reactant, therefore the final mass must also be 100 g.

adelina 88 [10]

Answer:

Image result for Based on the traits, which traits were most prevalent in the class? Did you have more traits aligned with the dominant traits or more that were rare? If you have a rare trait, which do you have?

The Big Five personality traits are extraversion (also often spelled extroversion), agreeableness, openness, conscientiousness, and neuroticism. Each trait represents a continuum. Individuals can fall anywhere on the continuum for each trait. The Big Five remain relatively stable throughout most of one's lifetime.

<span>M(NO</span>₃<span>)</span>₂<span> fully separates into M</span>²⁺<span> and NO</span>₃<span> </span>²⁻<span> </span><span>and M(OH)</span>₂<span> partially separates as <span>M</span></span>²⁺<span><span> and 2OH</span></span>⁻

<span>M(NO</span>₃<span>)</span>₂<span><span>     </span>→        M</span>²⁺<span>      +          2NO</span>₃²⁻

<span>0.202 M                 0.202 M</span>

 

<span>     M(OH)</span>₂<span>(s)        ↔        <span>M</span></span>²⁺<span><span> (aq) +          2OH</span></span>⁻<span><span>(aq)</span></span>

<span>I                                         -                            -</span>

<span>C   -X                                +X                        +2X</span>

4.45 * 10∧-12        =          (0.202 + X ) (2X)²

Since X is very small, (0.202 + X ) = 0.202

23+7-2x=8x solve for x​
weqwewe [10]

Answer:

3

Explanation:

23+7-2x=8x

(23+7=8x+2x) = (30 = 10x)

Isolate x:

30/10=10x/10

3 = x
