Answer:
Developer
Explanation:
A <u><em>developer </em></u>is an oxidizing agent that, when mixed with an oxidation hair color, supplies the necessary oxygen gas to develop color molecules and create a change in hair color.
Mostly hair colors are used to dye the gray hairs. Hair colors are mixed with developer which is act as oxidizing agent. The wisely used developer is hydrogen peroxide. The hair color is made of ammonia and oxidative tints.
These tints consist of small precursors of uncolored dye. These combined with hydrogen peroxide and form large tint molecule. These are then diffuse into cortex of hair and can not get off during shampoo.
These are termed as permanent hair colors.
Answer:
5.8 L
Step-by-step explanation:
This looks like a case where we can use the <em>Combined Gas Law</em> to calculate the temperature.
p₁V₁/T₁ = p₂V₂/T₂ Multiply both sides by T₂
p₁V₁T₂/T₁ = p₂V₂ Divide each side by V₂
V₂ = V₁ × p₁/p₂ × T₂/T₁
=====
<em>Data</em>:
p₁ = 5.6 atm
V₁ = 20 L
T₁ = 35 °C = 308.15 K
p₂ = 23 atm
V₂ = ?
T₂ = 95 °C = 368.15 K
=====
<em>Calculation:
</em>
V₂ = 20 × 5.6/23 × 368.15/308.15
V₂ = 20 × 0.243 × 1.19
V₂ = 5.8 L
Answer: c
Explanation : because it make sense the most (srry if im wrong!)
Water is H2O. hydrogen atom is H1 O2
so hydrogen atom is H2
Density = mass/volume
Density = 81g/0.9cm³
Density = 90g/cm³
