Answer:
An atom consists of a positively charged nucleus, surrounded by one or more negatively charged particles called electrons. The positive charges equal the negative charges, so the atom has no overall charge; it is electrically neutral. ... The nucleus of an atom contains protons and neutrons
Explanation:
1. Make sure it isnt something other than a ghost(i.e. something falling)
2. Record what you see and hear
3. See if anyone hears the same thing as you(unless your home alone)
4. Be confident and dont be fearful because ghost sense fear
5. Pray or perform an exorsism( if this is part of your religion)
6. After the ghost leaves, clean up.( like literally mops the floors and stuff. it keeps the ghosts out)
Good Luck ! :]
Answer:
1.02 × 10⁻³ g
Explanation:
Step 1: Given data
Number of moles of titanium (IV) oxide in 1 jelly bean (n): 1.28 × 10⁻⁵ moles
Step 2: Calculate the mass (in grams) corresponding to 1.28 × 10⁻⁵ moles of TiO₂
To convert moles to mass, we need a conversion factor. In this case, it is the molar mass of TiO₂: 79.87 g/mol.
1.28 × 10⁻⁵ mol TiO₂ × 79.87 g TiO₂/1 mol TiO₂ = 1.02 × 10⁻³ g TiO₂
The ionization constant equation is:
=1.0 ×
at 25°C
the option is 1.
Explanation:
Sometimes in pure water one proton of the water molecule(hydrogen ion) will get attracted to the lone pairs present in another water molecule.This causes the hydrogen ion to leave the present water(leaving the
behind) molecule ad gets attached to another water molecule leading to the formation of the hydronium ion(
,hydronium ion).
This process is called auto-ionization of water because the water molecule ionizes into
and
ions.

As such the equilibrium constant,which is measure of concentration of products to concentration of reactants,will be very slow.
∴the ionization constant of water at 25°C is 1.0 ×

Answer:
12.8seconds, 14.6seconds, 16.4seconds
Explanation:
the answers should b right as long as it is increasing in trend.
the reason why is bc of lower vol of hcl, and higher vol of water present. there is amount of hcl molecules present per volume. lesser chance of collisions, lower rate of successful collisions to poduce CO2
