Answer:
multiple things.
Explanation:
DNA evidence collected from a crime scene can be linked to a suspect or can eliminate a suspect from suspicion. During a sexual assault, for example, biological evidence such as hair, skin cells, semen, or blood can be left on the victim's body or other parts of the crime scene.
Answer:
He
Explanation:
From Graham's law of diffusion, lighter or less dense gas tends to diffuse faster than denser gas amongst the list, He is the lightest gas and so will diffuse faster
The Ksp of AgOH will be 1.98×10⁻⁸
According to the question,
The chemical reaction is:
AgOH (aq) + HCl (aq) ---> AgCl (s) + H₂O (aq)
Now, acc. to the formula:
C₁V₁ = C₂V₂
(AgOH) (HCl)
By substituting the values, we get:
C₁ x 250 ml = 0.0136 x 2.60 ml
C₁ = 0.000141
Now:
AgOH → Ag⁺(s) + OH⁻(s)
Hence,
Ksp will be:
= s²
= (0.000141)²
= 1.98x10⁻⁸
<h3><u>The value of Ksp(Solubility product constant)</u></h3>
When a chemical substance in the solid form is in chemical equilibrium with a solution of that molecule, a solubility equilibrium is a sort of dynamic equilibrium that develops. The solid may dissolve chemically reacting with another component of the solution, such as acid or alkali, or dissolving unaltered.

Answer:
2.8 × 10² g
Explanation:
Given data
Step 1: Convert 25°C to the absolute scale
When working with gases, we have to convert the temperatures to the Kelvin scale, using the following expression.
K = °C + 273.15 = 25°C + 273.15 = 298 K
Step 2: Calculate the moles of chlorine gas
We will use the ideal gas equation.
Step 3: Calculate the mass of chlorine gas
The molar mass of Cl₂ is 70.91 g/mol. Then,
well if you round to the nearest cent the number 0.332 move the decimal down 2 time so it would be 33 it the the answer would be "a"
im sorry if im wrong im trying my best to answer correctly please don't report my answer cause brainly mighty remove my account again.xd
